Can I Still Be Productive On Only 4 Hours of Sleep?

Get The Sleep You Can

Stay Awake, Stay Alert

Michelangelo, Florence Nightingale, Thomas Edison, Margaret Thatcher and Martha Stewart to name a few, only slept for up to four hours each night. Impressive stuff and it appears to have paid off as we know about their contributions to the advancement of our species.

Edison was particularly critical of sleep and stated publicly that it was a “waste of time”. For better or worse, people have tried to emulate the success of those like Edison and sacrifice their sleep in order to get more done and gain an advantage over the competition.

The need to get ahead can take its toll on individuals and societies which can lead to many unforeseen bad consequences, one of which is being able to clearly think and evaluate situations in a logical manner. Being overworked and stressed seems to be antithetical to being productive and healthy, but there are many examples of people (like those mentioned above), that have overcome these obstacles despite not having the recommended 7-9 hours of sleep per night.

Is it that some of us are naturally endowed with the ability to have much less sleep than others without compromising their health, or is it that something else is at work here and that having less than six hours of sleep per night can have serious health implications?

Productivity vs Sleep

A small group (1 to 3 percent) of the population are among the “sleepless elite “ who are able to get by happily on just a few hours of sleep.

Whether they’re part of this lucky group or have been driven by the pressures of their jobs, we’ve compiled a list of successful executives, political figures, and entertainers who have shunned the 8 hour mantra and managed to rise to the top.

Carolyn Cutrone and Max Nisen, 19 Successful People Who Barely Sleep, Business Insider, Sep 18, 2012, source: Successful People Who Barely Sleep

There have been many articles and online video blogs that follow the current trends of the rich and successful. In many of the posts the focus has been on either how naturally talented their subjects are, how hard they work or both.

The implication is that as a ‘normal’ person watching these elites from the outside, you don’t want success as much as they do or you don’t have the talent to make it to their lofty heights. Your lack of success is down to you not putting in enough time and effort to develop yourself to their level, besides what are the chances of you being in that top 1 to 3 percent like the elites.

Many workers and students also feel that they have to put in the extra time and effort in order to stand a chance of being able to compete with their peers and the broader population in general. A popular approach to this kind of pressure is to work longer hours and shorten the amount of time spent in leisure activities and turning off after work; a practice that can negatively affect the quality and quantity of sleep.

We should also consider that work pressure doesn’t affect everyone the same. And that work and study pressures can be temporary. Even so, care must be taken as volunteering ourselves for sleep deprivation (even for short periods) can have a negative effect on our general health and wellbeing.

 

Self Sleep Deprived

Our leisure time might also be having an effect on our sleep. Many of us spend a lot of time in front of various devices’ screens, the light from which can effect our bodies’ production of melatonin. Melatonin is our bodies’ natural way of regulating how tired we feel and helps us to prepare to sleep. Melatonin production is affected by our exposure to light and therefore too much light in the evenings (especially before going to bed) interferes with our sleep and reduces the quality of the sleep that we get.

This can lead us to being sleep deprived which most certainly reduces our productive ability. Not getting enough sleep can have the following effects:

  • Difficulty paying attention
  • Inability to focus
  • Reduced motivation
  • Reduced problem solving ability
  • Confussion
  • Irritability
  • Memory lapses
  • Slower reaction times
  • Reduced ability to process information
  • Increase in a lack of judgement

A lack of sleep can also increase the risk of suffering from heart attacks, stroke, hypertension, obesity, diabetes and depression.

Increased Sleep Increases Productivity

Given what we know about the effects of lack of sleep on our productivity and health, to combat these effects ultimately we have to get more good quality sleep.

However this is more easily said than done. Below are some tips that you can incorporate into your daily routine to help you get enough sleep and spend less time at work/studying by doing more of the things that will help you to perform at your best.

  • Get to bed between 9pm and 10pm as this will help facilitate you getting enough good quality sleep as your body naturally starts to produce melatonin which helps you sleep better.
  • Don’t use any light emitting gadgets just before you go to bed. Give yourself a couple of hours to wind down and allow your body to start producing melatonin.
  • Organise your work so that you do your most difficult work around 10am (if you are a morning person), or 3pm – 6:30pm (if you’re an afternoon person).
  • Avoid caffeine and alcohol just before going to bed.
  • Take regular breaks rather than one long big break throughout the day. Dividing your task into 25 minute blocks with a five minute break between each block for the day will help keep you focused and help keep fatigue at bay.
  • Include regular exercise in your daily routine (even a 25 minute walk has been proven to positively affect the quality of peoples sleep later in the evening).
  • If you find yourself struggling to stay awake during the day or suffering from brain fog, take a 10-20 minute nap. Studies have found that napping helps with your alertness and focus immediately after.

Review

So, can we be productive with only four hours of sleep? The answer is it depends. Limiting the amount of times that you sleep for under four hours can be helpful if you have a tough work or study load, but it shouldn’t be the norm.

Yes there are some people that can get by with very little sleep, but keep in mind that they are a small percentage of the population. If you can still produce your best quality work with only a few hours sleep regularly, then don’t mess with what works.

Just be mindful that the less hours you get to sleep, the greater the risk to your health.

Afterword

The conclusion from research into polyphasic sleep and short-sleepers is clear. When it comes to sleep, there are no quick fixes. As a result, it is vital that everyone knows how to get a good night’s rest.

Need to get into Sync?

Tune Your Circadian Rhythm

Feel better, be better…

It’s good to be in sync. Things seem to flow effortlessly, work ain’t such a drag and life is good. Being out of sync though, is not great. Doing the most basic of tasks take a lot of effort, work is unbearable, and life feels like you’re going nowhere.

A big challenge for the developed world is balancing our family, work and societal needs with our own needs and well being. Many of the comforts and conveniences that we take for granted depend on someone having to sacrifice their well being so as to maintain what we’ve become used to.

Likewise many of us sacrifice our well being and health by unconsciously doing things in ways that can knock us out of sync with our body’s rhythms which in the long term can be very detrimental to us.

A central component of our well being is for our circadian rhythm to be in sync with our environment. Being out of sync has serious implications for health, well being and productivity as well as be costly for society in general.

Briefly put, our circadian rhythm regulates our responses to a solar day and regulates when we wake up and when we feel tired enough to sleep. It does a lot more and we’ll go into detail later. What’s important to know right now is that our circadian rhythm has taken time to evolve in our species so that we can better regulate our lives according to the amount (or lack thereof) of daylight. It has done a fantastic job up until the industrial age when artificial light sources have extended our waking hours.

In now days with computers, smartphones and gadgets that all emit light we may have accidentally broken our circadian rhythm and be out of sync with ourselves and environment.

The Drift

Before the invention of the electronic light bulb most people followed regular waking and sleep cycles that were seldom disrupted. The majority of the world lived an agrarian lifestyle and as such their daily routines were closely aligned to the rising and setting of the sun.

As the industrial age took hold a large amount of the working populations in Europe and America migrated from the farmlands to the industrialised cities hoping to improve their and their families’ prospects. In return workers and their families had to conform to new working practices which were increasingly at odds with the old agricultural regime.

Work hours didn’t necessarily correspond to the old sunrise to sunset model and people found themselves working longer hours and working night shifts. This situation worsened with the invention of the electric light bulb. Due to production demands and the eager adoption of electronic lighting, people were now able to work longer hours and shift work became widespread.

Workers soon began to feel pressured to work longer hours and do more shifts as the competition was stiff and people wanted to succeed. There was a perception that feeling tired wasn’t manly and that you were somehow lazy and not ambitious enough to make it big.

Thomas Edison created much of this bright new world. With regard to the changing relations of work to sleep, the inventor of practical incandescent lighting was not only the father of the night shift. He also took a prominent part in criticizing and even ridiculing sleep as an inefficient and immoral indulgence.

Edison was perhaps the most famous and widely admired American of the late nineteenth and early twentieth centuries, a hybrid celebrity renowned for his imaginative genius and his entrepreneurial acumen.

A tireless self promoter whose greatest invention was himself, Edison spent considerable amounts of his own and his staff’s energy in publicising the idea that success depended in no small part on staying awake to stay ahed of the technological and economic competition.

Derickson, Alan. Dangerously Sleepy (pp. 4-5). University of Pennsylvania Press, Inc.

Out of Line

It wasn’t long before the effects of overworking and under sleeping started to take their toll on the working population. Although workers and their advocates were successful in getting legislation passed to limit the number of hours they worked, it wasn’t an easy battle. For the rest of the twentieth century there would be various efforts taken across the world to address the issue of working long hours and its effects on society.

Unfortunately, just as workers have started to win some hard fought concessions with regards to the amount of time that they spend working, we are unconsciously volunteering ourselves to potentially dangerous outcomes due to the amount of night time light pollution we expose ourselves to.

Flat screen tvs, smartphones, electronic tablets, computers and bright lighting are all having similar effects on our circadian rhythm as working night shifts or long hours due to the amount of light that we expose ourselves to. This is important as our circadian rhythm uses light to determine the appropriate responses to take for any given time of day.

Using light as a cue our circadian rhythm helps regulate our tiredness and quality of sleep. In a well aligned day:

  • 07:00 – Our bodies stop producing melatonin and this helps us to wake up
  • 10:00 – By this time our body has fully woken up and we are at our most alert time of the day (approximately).
  • 12:00 – 14:00 We experience our mid afternoon crash
  • 18:30 We experience our peak energy for the day
  • 21:00 – 22:00 our body starts producing melatonin
  • 02:00 Our deepest part of the sleep cycle

Exposing ourselves to the light emitted by our electronic devices is detrimental to our sleep and circadian rhythm as light can affect our body’s ability to accurately respond to what time of day it is. The result is poor sleep and daytime fatigue. If you’ve ever woken up and felt like you didn’t get enough sleep, the chances are that your circadian rhythm is out of sync.

Pervasiveness and intensity of nighttime light exposure is unprecedented in our history.
When exposure to light is mistimed or nearly constant, biological and behavioural rhythms can become desynchronised, leading to negative consequences for health. The relationship among mood disorders , light, and circadian rhythms have long been recognised.
Many mood disorders are either characterised by sleep and circadian rhythm disruption or precipitated by an irregular light-dark cycle.

Walker, W., Walton, J., DeVries, A., & Nelson, R. (2020). Circadian rhythm disruption and mental health. Translational Psychiatry, 10(1),

Studies have highlighted that when our sleep cycle is out of sync with our circadian rhythm, the risk of suffering from any of the following conditions is increased greatly:

  • Lower glucose metabolism
  • Cardiovascular problems
  • Impaired attention
  • Dysphoric mood
  • Difficulty learning and thinking

Getting In Sync

Thankfully there are a few things that you can do to help yourself get back on track, which require a little bit of effort and can be quite enjoyable once you embrace them.

Sleep Routine

  • Get to bed between 9pm and 10pm as this will help facilitate you getting enough good quality sleep as your body naturally starts to produce melatonin which helps you sleep better.
  • As your body stops producing melatonin around 7am, set this as your regular wake up time (even on weekends).
  • Don’t get overly warm or cold when you go to bed.
  • Don’t use any light emitting gadgets just before you go to bed. Give yourself a couple of hours to wind down and allow your body to start producing melatonin.

Daytime Routine

  • Organise your work so that you do your most difficult work around 10am (if you are a morning person), or 3pm – 6:30pm (if you’re an afternoon person).
  • If you are going to consume caffeine don’t do it past midday. If you suffer from a mid afternoon crash then have your last caffeine intake between 12pm and 2pm.
  • Take regular breaks rather than one long big break throughout the day. Dividing your task into 25 minute blocks with a five minute break between each block for the day will help keep you focused and help keep fatigue at bay.
  • Include regular exercise in your daily routine (even a 25 minute walk has been proven to positively affect the quality of peoples sleep later in the evening).
  • If you find yourself struggling to stay awake during the day or suffering from brain fog, take a 10-20 minute nap. Studies have found that napping helps with your alertness and focus immediately after.

Review

Keeping your circadian rhythm in sync is just as important to your health as regular exercise. Going to bed at regular times and not using light emitting devices close to the time that you go to bed will help keep you in sync.

You also get the benefit of an increase in your ability to focus and a feeling of increased energy just by simply following the steps outlined in this post.

Afterword

Rather than celebrate the night, sleep and dreaming are now treated as annoying interruptions to our all-important lives. Living in a world that hasn’t had a good night’s rest for years has finally taken its toll. The vast majority of school children and students now arrive for their classes severely sleep deprived, adult sleep debt is at a record high, the demand for sleeping pills is rising year on year, and millions of people go about their daily business in a zombie-like state that is ruining their relationships, health and productivity. Perhaps more than at any other point in history, there is now an urgent need to change our attitudes towards the night. I believe that this will require nothing short of a revolution.

Time, Technology and Your Tiredness

Know When to Stop

Stay Alert, Stay Focused

To me, one of the weirdest things that we experience is time. Whenever I’m bored or doing something that I don’t want to (like being in a pointless meeting, or stuck in an uninteresting class at school), time seems to move extremely slow, and I’m amazed how five minutes can feel like thirty.

In contrast, when I’m really engaged in what I’m doing time flies. I lose track of time and feel disappointed when it’s time to stop, and again find myself amazed that two hours have past when they only felt like twenty minutes!

I’ve read lots of books and endless online videos about this phenomena, and ultimately they all tend to agree that time is subjective, fair enough. But what about how we are affected by our subjective experiences of time passing?

Something that I’ve noticed in myself, is that the feeling of tiredness is always there, it’s just felt at different stages. When I’m bored I usually feel sleepy and find it difficult to focus on what is being said or the task that needs to be completed. When I’m fully engrossed in a task or presentation, I feel full of energy and feel like I can keep going without stopping, but soon after I finish it feels like everything is moving in slow motion and I suddenly notice how drained I feel.

So what is going on?

No Time

People want to get something out of their time and their lives. It is all about getting a lot done, and to be done with it so that one can move on to something else…
The constant reorganisation of workplaces (now an unquestioned norm of a modern organisation) implies that we are in a state of change all the time. The goal of efficiency means, without exception, an increase of intensity at work. In short, more has to be done in less time.

Widerberg, K. (2006). Embodying Modern Times. Time & Society, 15(1), 105-120.

It is an unfortunate fact of life these days that there is an increasing expectation for us to perform at ever increasing levels of productivity. Very few of us have a standard work or study week. This unpredictability makes it difficult for us to effectively plan the amount of time that we spend working or studying.

Even with having the ability to work from home, we may find that we actually spend more time working than we would have if we were in the office (although, I prefer working from home). Wherever we work or study, many of us can find that we are unable to switch off completely and as a result find it difficult to relax and be fully engaged in our own lives.

Whether our professions allow us to work remotely or not, our work loads are increasing and we can feel that we don’t have enough time to get things done. The pressure to perform can keep us fully engaged whilst working or studying without us realising that we are wearing ourselves down.

The early signs of our increasing tiredness include feeling irritated and finding it increasingly difficult to concentrate whilst at work, and feeling burnt out but unable to get adequate rest when at home.

 

Unable to Stop

“I like the job, it is self-developing and the technical development has its way. Everybody has mobile phones, home computers, and Internet, and that goes for me as well. This increased activity is what we live for, it is our daily bread and it has its costs. When I come home my work day is not over. I do notice that it wears you down, especially when you have not had a holiday for some time”.

Widerberg, K. (2006). Embodying Modern Times. /Time & Society,/ /15(1),/ 105-120.

Our inability to switch off after working or studying is worrying. Without being able to completely switch off we set ourselves at more risk of suffering from various health issues, one of which is inadequate sleep.

Unfortunately, it is difficult for us to notice when we are worn down, a situation which is made increasingly difficult to acknowledge due to the normalisation of overworking.

When it is normal to have too much to do, it is likely that it is also normal to be tired and worn out, and to have bodily symptoms. Aches in the back, neck, head, stomach, and joints, and sleeping problems seem to have become too common to be worth talking about. That is just the way it is, it seems, for all of us.

Widerberg, K. (2006). Embodying Modern Times. Time & Society, 15(1), 105-120.

This is a worrying situation to be in as most of us don’t realise the dangers that we are volunteering ourselves for. Jagdish Khubchandani and James H. Price in their article “Short Sleep Duration in Working American Adults, 2010 – 2018” highlight that sleep problems aren’t acknowledged as a major health concern and explain the associated mental and physical illnesses that we can expect if this issue isn’t addressed (see below):

  • Loss of productivity
  • Premature mortality
  • Increased risk of type-2 diabetes
  • Strokes
  • Hypertension risks
  • Increased risk of coronary heart disease
  • Anxiety
  • Alcohol abuse
  • Workplace absenteeism
  • Presenteeism (low work performance)
  • Unstable moods
  • And suicidal ideation

Time and Technology

Knowing that it so easy to lose track of time and have a sense of how tired we actually are is easy, but what can we do about it?

Improving sleep hygiene goes a long way to help correct a lot of the issues, and some of the steps that you can take to help yourself are:

  • Go to bed and wake up at the same time daily. This helps your body’s circadian rhythm adjust to your sleeping routine.
  • Get between seven to eight hours of good quality sleep. Both quality and quantity are important to help you feel refreshed and rested when you wake up.
  • Exercise regularly. It helps with improving your health and helps improve the quality of your sleep.
  • Get outside more and get plenty of bright daylight.
  • Avoid caffeine, alcohol and tobacco as they reduce the quality of your sleep.

The things that you can do to help yourself whilst working/studying are:

  • Take regular breaks whilst working. Use the Pomodoro technique (or any other productivity process) to help set specific blocks of time for you to work. Once the block is complete, take a five to ten minute break, then start again. Working this way helps to keep you focused and reduces the risk of you working whilst tired.
  • Work no more than forty hours a week. Organise your work so that you can have enough rest when you’ve finished working for the day without having to continuously work long hours.
  • Use technology to help you keep alert. Our Apple Watch app, V-CAF Stay Awake Stay Alert, helps you keep track of your tiredness by notifying you when your tiredness increases. Using it whilst working will help to let you know when your body says it needs to take a break, helping you to be more efficient and productive.
  • After finishing work, go for a walk before coming home. It can help to de-stress you and help you relax and switch off from thinking about what you did that day, and how you’re going to deal with tomorrow.

Decide what your priorities are. If your health is important to you then take the necessary measures that you need to, to protect yourself. Same goes for your family and work life. Make a list of what is important to your quality of life and stick to it as best you can.

Review

Ultimately what I’m saying in this post is to make time for yourself. It’s easy for me to tell you not to obsess over work/studying and to take it in your stride, but I know it isn’t easy to do at all.

Whether you find yourself getting bored and that makes you tired, or you overwork and don’t realise how tired you are, be aware of what your body is telling you and step back when you need to.

Afterword

“If someone asks you how to write your name, would you bark out each letter? And if they get angry, would you then return the anger? Wouldn’t you rather gently spell out each letter for them? So then, remember in life that your duties are the sum of individual acts. Pay attention to each of these as you do your duty . . . just methodically complete your task.”

No Time For Sleep!?

You’d Better Get Yourself Some

Boost your sleep, boost your productivity…

There are times in our life when we find that we have too much to do and something has to give. Until a few years ago, that something that gave was my sleep!

Play hard, work hard was my mantra, and I certainly did that! So whenever I had a tight deadline or too much to get done, I would just stay up and work late and then wake up early and continue where I left off.

This worked out great for a short while but came back to bite me in a big way later on. And I’m not unique it this respect. According to a number of studies, an increasing amount of us are getting less sleep now than we did 10 years ago.

Nobody knows why this is the case but we do know that the medium to short term effects on our lives personally, and the cost to society as a whole, are too high a price to pay.

Duration and Quality Decrease

Compared to 2010, the odds of short sleep duration were statistically significantly higher in 2018 despite adjusting for demographic characteristics (25% higher) and occupational characteristics (22% higher). In 2018, the highest levels of short sleep duration were found for the following categories of jobs: protective service and military (50%), healthcare support occupations (45%), transport and material moving (41%), and production occupations (41%).

Khubchandani, J., & Price, J. (2020). Short Sleep Duration in Working American Adults, 2010–2018. /Journal of Community Health,/ /45(2),/ 219-227.

There’s no getting around it, we need enough good quality sleep; but the pressures of life, work and/or studying may all be contributing to us not getting the sleep that we need.

Research has found that there may be a link between stress and a decrease in the amount of hours that we spend sleeping. People suffering from stress often find it difficult to get to sleep, or discover that they often wake up during the night and by the time it gets to the morning, still feel tired.

Then there are those of us who, due to economic reasons, work late or night shifts. This is extremely difficult to do as we have to fighting against our own body clock, which is telling us to go to sleep. Once the night shift is finished, sleeping through the day may help catch up on some of our sleep, but the quality and quantity is often reduced, which often means returning to work not fully rested.

Risking Your Health

Almost a third of working adults in the U.S. get inadequate quantities of sleep. Most likely, those who work long hours, engage in changing shifts, or those in high stress professions that have minimal control over their work and life schedules are at risk of short sleep duration and the subsequent social, physical and mental health consequences of sleep problems.

Khubchandani, J., & Price, J. (2020). Short Sleep Duration in Working American Adults, 2010–2018. /Journal of Community Health,/ /45(2),/ 219-227.

By not getting enough sleep, you are putting your health and well being at risk. I know it’s difficult, and I used to just push through the tiredness to meet my deadlines, and because I did it often I thought I was doing well. It was only when colleagues pointed out that some of my work wasn’t up to my usual standard that I took a step back to see what was going on.

When you are stressed, tired and under pressure, it is easy to miss the tell tale signs that your body is giving you, trying to warn you that you need to stop and take a break.

Continuing to work when you’re not fully rested makes working more difficult and can be dangerous to you and potentially others. Tiredness often makes things worse as it impairs our ability to think clearly and slows down our cognitive abilities.

It’s logical to assume that if we can’t think as clearly as we can when we are fully awake, then our productivity will also suffer when we are tired. Tiredness also increases the likelihood that we will make more errors at work, which can be costly for our business or employer as well as to you.

The cost to your health cannot be overlooked. Just by not getting more than 7 hours of good quality sleep you are more likely to suffer from the following chronic diseases than those who sleep 7 hours or more (per 24 hour period):

What You Can Do

The simple answer, get more good quality sleep; but I know from personal experience that it’s not so straight forward. Work, study or life pressures make it difficult for us to do what we know is best for us.

So, what to do?

  • Sleep
    • Go to sleep and wake up at regular times
    • Don’t work past 9pm if you can
    • Avoid consuming caffeine past midday (or better yet, give it up)
    • Make your bedroom as dark as possible
    • Don’t read, watch tv or take gadgets to bed
    • Keep your bedroom as quiet as possible
    • Make sure you are cool in bed
  • Whilst Awake (during the day, usually)
    • Take regular nap breaks (but no more than 20 mins max)
    • Do more exercise during the day, (use at least two breaks a day for walking outside or stretching – even a 10 minute walk can help improve your sleep at night)
    • Keep yourself mentally active throughout the day (keep your mind busy and stimulated)
    • Eat healthier foods (fruits, vegetables, non processed meats, eggs, butter, etc) rather than processed foods with lots of sugar and salt added to them
    • Know when you are tired (it helps to head to bed when you are actually tired, rather than just because of a schedule. Also knowing when your tired throughout the day can help you time your nap breaks strategically, which in turn helps your focus and productivity – see what we say about this topic in the review)
  • Shift workers
    • Where possible, explain to your employer the benefits of a well rested employee and ask for more considerate shift planning (for example no back to back shift working – one week late shift, the next week early shift)
    • Have regular health checks to make sure that you’re not stressing your body to its limits and risking a chronic illness.

Review

It’s easy to overlook when we are tired and as a result put ourselves at risk from chronic diseases and mental health issues. Our health is primarily our responsibility and as a result, it would be wise for us to prioritise our sleep and exercise before our work (but this is easier said than done).

Which brings me to the issue of knowing when you are tired. We developed V-CAF Stay Awake Stay Alert(an Apple Watch app) to help you know when your tiredness levels are increasing so that you can take the appropriate actions necessary to either wake yourself up, or to take a break. V-CAF also links to your iPhone and iMac or Apple Laptop so that you can be notified when your alertness levels are dropping.

I hope that the points that have been highlighted in this post will be useful to you in your personal and professional life, if so, please comment below.

Thanks 🙂

Combating Tiredness In A World That Never Sleeps

How do you feel?

Change the way you play the game…

Tiredness whilst working affects us all at some point, and it affects some more than others. When talking with colleagues the quick solution tends to be to consume more caffeine.

Although this works in the immediate short term, over longer periods the efficacy of caffeine to keep us feeling awake starts to reduce, and so typically we consume more.

When it comes to sleep hygiene (especially at the work or study place), there seems to be a high level of ignorance as to the long and short term effects of tiredness on our health and productivity.

In recent years there has been a push by corporations to help employees and students deal with the increasing demands of work loads and performance targets, but not much on actioning strategies that address sleep related issues.

So what can you do as an individual to address these issues?

Work vs Sleep

Increased work and study loads, as well as an increase in online activity (games, social media, news sites and special interest sites, to name a few), as well as pressure to spend time with family and/or friends have made it difficult to maintain healthy sleep practices over a long period of time.

Whether studying or working, the default strategy for most is to increase the amount of time they spend working. At first glance it seems intuitive and seems to be corroborated in studies such as “Just do it! Study time increases mathematical achievement scores for grade 4-10 students in a large longitudinal cross-country study”:

These results support the idea that students, in particular low-performing students, can boost their academic abilities to upper levels when increasing their study time.

Spitzer, M. (2021). Just do it! Study time increases mathematical achievement scores for grade 4-10 students in a large longitudinal cross-country study.European Journal of Psychology of Education,OnlineFirst,1-15.

However, as we shall see later, quantity doesn’t always out do quality, and a little deeper reading into the above study alludes to the fact that “seeking out the right answer is the first step to get it right”. But most take it on the surface level and equate time spent doing something as equal to time spent doing the right thing.

Unfortunately if spending more time to solve a problem is the only tool that we have to solve our work and study load problems, we soon find that we never have enough time to get things done, whilst at the same time increasing the stress levels we expose ourselves to.

The need for 24-hour a day operations in developed countries has increased the likelihood that workers will experience fatigue, sleepiness, and decreased performance sills as part of their daily lives. Evidence also suggest that the more one works, the less time the person sleeps, even on days off.

Pilcher, J., & Morris, D. (2020). Sleep and Organizational Behavior: Implications for Workplace Productivity and Safety.Frontiers in Psychology,11,

 

Is It Worth It?

Fatigue affects our basic cognitive functions which decreases our job and safety performance. In the long-term, fatigue has both health and economic consequences.

National Safety Council

Working more when we are tired will usually not get us the results that we want and can increase the risk of us suffering from any of the following:

  • Obesity
  • Sleep apnea
  • Cardiovascular disease
  • Irritability
  • Reduced immune defence reaction

Further research suggests that our cognitive abilities decline when working whilst we are tired, making it harder to complete simple tasks and to focus. We become slower, make more errors and the quality of our work reduces, which implies that we’ll have to spend more time to correct the mistakes that we made when were tired (or in other words, spend more time working).

What You Can Do

Knowing this, the best thing that you can do is take action. One of the first things to do is to learn what you can and then implement what you know. The article and research paper that helped me to write this article is excellent and has a wealth of information for individuals as well as companies and can be found here:

Sleep and Organizational Behavior: Implications for Workplace Productivity and Safety

And here are few more tips to help get you started:

  • Sleep
    Make your sleep your priority. Don’t sacrifice your sleep for productivity gains or family/social reasons (where you can). Quantity and quality are equally important so try to get between 7-9 hours of quality sleep (by avoiding alcohol, and not consuming caffeine past midday). Exercising (even a 20 minute walk counts), also helps improve the quality of your sleep. Also, go to bed and wake up at the same times regularly, so that your circadian rhythm can adjust accordingly, which also helps improve the quality of your sleep.
  • Working hours
    Generally speaking working more than 50 hours a week, or 10 hours a day can be very taxing and tiring, so where possible adjust your work schedule to reduce the amount of tiredness that you experience. Avoid early starts and late finishes as you’ll be working against your body’s natural waking and sleeping cycle, which in turn increases the likelihood that you’ll exhaust yourself. Shift workers should try not to work too many late shifts in a row and should speak to their employers about arranging their work schedules so that they have enough time to recover after completing a series of night shifts, early morning shifts, rotating shifts or irregular shifts.
  • Rest Breaks
    Take regular work breaks and try to formalise them where you can. Breaks are excellent because they give you a chance to step away and where possible take a nap, which reduces the chances of you micro sleeping on the job. Scheduling in just a 10 minute break every 50 minutes can make a world of difference. In Sleep and Organizational Behavior: Implications for Workplace Productivity and Safety, June J. Pilcher and Drew M. Morris highlight that wearables, (smart electronic devices such as a smart watch or fitness tracker), may play an important role in health promotion programs, whereby teams can be set up to help monitor and encourage participants to move more whilst at work. Apps such as V-CAF (an Apple Watch app) take this step further by notifying users when their alertness levels are dropping, thereby informing them of the need to take a break automatically.
  • Long commutes
    Workers that have a long commute to work also increase the likelihood of tiredness and fatigue as the time spent traveling is time that they don’t spend resting, but at the same time adds to the length of their already long day. Where possible, cut your commute times down by arranging to work from home or changing location. If you travel by public transport, when you can take a quick snooze. It’s far from ideal but it’s better than nothing.
  • Stressful and/or monotonous jobs
    Physically and mentally demanding jobs are the most difficult to fix. Unless you can find alternative employment, there isn’t much room for you to change things. This is where all of the above stated points come into their own as you will have to incorporate them all into your daily routines to help mitigate the risks to your health. If you are an employee, you can talk to your employer or HR department to see what steps they can take to help you whilst you’re at work. If you’re self employed, then you’ll have to organise your work process around what’s best for your health, which can be quite challenging, but well worth the effort. Use the suggestions above (and throughout this blog) to help you.

Review

In a world where it appears as though there is never ending increasing competition with decreasing alternative opportunities, it is easy to fall into the cycle of working for longer hours per day, whilst cutting the amount of time you get to recover and sleep.

Although not perfect, by trying some of the above strategies and finding out more about how a lack of sleep can effect the quality of your health, study, work and family life, you can take some positive action to help yourself cope better.

  • Sleep – more quality and quantity
  • Working hours – no more than 50 hours a week, 10 hours a day, and not starting too early, or working too late
  • Rest breaks – take at least a 10 minute break for every 50 minutes at work. If possible have a nap
  • Long commutes – avoid them where possible
  • Demanding jobs – restructure your work process where possible

Afterword

“Do each day all that can be done that day. You don’t need to overwork or to rush blindly into your work trying to do the greatest possible number of things in the shortest possible time. Don’t try to do tomorrow’s or next week’s work today. It’s not the number of things you do, but the quality, the efficiency of each separate action that count. To achieve this “habit of success,” you need only to focus on the most important tasks and succeed in each small task of each day.”

Does Alcohol Help You Sleep Better?

Nightcaps

Avoiding the gin and juice

Depending on how much I used to drink, I thought that in some cases alcohol helped me to have a deeper level of sleep. No problem if I had a hangover the next day, all I needed was a few shots of coffee and loads of water and I’d be good.

However I made the mistake of drinking too close to a test once and thought that I could pull through with just coffee and water, but as you can guess things didn’t go according to plan.

As I have a few friends that drink heavily and always seem to bounce back unphased I wanted to figure out what I was doing wrong and what they did right. But, what I found out, with regards to productivity at least, changed my view of alcohol.

A Drink Helps Me Sleep

It’s understandable. You’ve had a long, stressful day and want to unwind. It feels like too much effort to get up and do some exercise. A glass of wine or a can of beer helps you to relax.

Soon after you find yourself feeling less tense but drowsy, and you may even fall asleep on the sofa. Or perhaps for the past few days you’ve been finding it difficult to get to sleep, but after a drink, you seem to fall asleep faster.

So how can this be bad for my sleep? When talking with friends about this it seems that we all tend to agree that a light drink actually helps your sleep and doesn’t affect your productivity the next day.

But then I found a study on the effects of alcohol on sleep, which I found surprisingly interesting, not just because it was an interesting read, but also because it challenged some of my assumptions about sleep and alcohol.

 

The Productivity Disruptor

According to the study, there have been many studies documenting the negative effects of even low dosages of alcohol on sleep quality and next day productivity.

Not surprisingly the heavier the drinking session, the worse the hangover effects, but also the worse the quality of sleep and next day productivity levels.

Relative to their habitual night of sleep, Sleep Quality was significantly worse after the drinking session that produced the hangover. On the hangover day, daytime sleepiness was significantly elevated.
…Sleep quality and daytime sleepiness were significantly associated with the presence and severity of various individual hangover symptoms.

Schrojenstein Lantman, M., Roth, T., Roehrs, T., & Verster, J. (2017). Alcohol Hangover, Sleep Quality, and Daytime Sleepiness. /Sleep and Vigilance,/ /1(1),/ 37-41.

The top reported hangover symptoms included but weren’t limited to:

  • Dry Mouth
  • Thirst
  • Sleepiness
  • Weakness
  • Drowsiness
  • Headache
  • Reduced reaction speed
  • Nausea
  • Concentration problems

What I found fascinating was the similarities between hangover symptoms and caffeine withdrawal symptoms. It may be the reason why I thought that drinking lots of water and having a few shots of coffee was a legitimate cure for hangovers, as when you have caffeine withdrawal symptoms, drinking a coffee helps get rid of those symptoms very quickly!

Sleep Quality

So although alcohol may make you feel drowsy and fall asleep quicker, it actually can have a detrimental effect on the quality of your sleep. Ok, so what should you do about it?

The easy answer, don’t drink close to bedtime (or give up alcohol completely) and get more sleep.

The more nuanced answer (for those that may suffer regularly from hangovers) is to:

  • Reduce the amount of alcohol that you consume when you have a busy schedule and don’t drink so close to bed time.
  • If you have a hangover whilst working, if possible take regular breaks and sneak a nap when you can.
  • Drink lots of water to rehydrate yourself.
  • It may be best to take the day off work to get yourself back to your normal productive self.

Review

Sleep is important, you don’t need me to tell you that. If you have a heavy workload or study schedule, it may be best to skip the drinks until things get a bit less hectic.

If you find that you have a hangover or just a bit fuzzy from the night before, be kind to yourself (and others) and take it easy until you are back to your normal self.

Afterword

If you are having difficulty focussing whilst giving up caffeine and/or alcohol, or in general, our app V-CAF can help. It’s an Apple Watch app that notifies you when your alertness levels drop so that you can take the appropriate steps to boost your alertness.

It’s available now on the App Store, download it today.

Feeling Sleepy?

Pay Down Your Sleep Debt

It pays better terms of interest…

Over the last few weeks I’d been feeling rather sleepy and put it down to the weather and it being the towards the end of the year. Work wasn’t particularly busy and hadn’t been out on the town for a while.

I then tried experimenting with my daily processes such as my nap lengths, when and what I ate and my exercise routines but I didn’t notice any change in my general feeling of being tired and sleepy.

Reluctantly, I thought I’d better make an appointment to see the doctor to see if there was anything interfering with my health, but before I did, luckily I stumbled upon a solution that worked, and was so simple I felt like “Duh! Why didn’t you try that sooner!”

Sleepy

Sleep Debt

I’m not the only one guilty of this. During busy and/or stressful times something has to give, and one of the easier things to lose track of is the amount and quality of your sleep.

As usual before this recent down time I was extremely busy in my personal and professional life, and going all in to sort things out and get things done.

Even though I stuck to my pattern of working until my alertness levels dropped and took short nap breaks, I missed the most obvious thing, that the quality and quantity of my sleep was slipping.

What Gives

Although I thought that I was on top of things, all my energy and focus was being spent on things outside of my being, at the expense of my health.

With hindsight it’s easy to look back and say what you should’ve done, but in the moment you can miss that the actions you take at that moment can directly affect your future, either positively or negatively.

Within a few days of finishing that last round of busyness I found myself feeling restless and needing something to do. This was the point where I should have kicked back and got my sleep back in check.

Instead I decided to catch up on things that I felt I missed out on and the not so fun things that had been neglected. As a result I found myself not only not catching up on my sleep, but also cutting into it as well!

My sleep debt was at all time highs! How could I tell? Simply by noticing how tired I was.

Sleep Strategies

As soon as I realised that I’d overlooked the obvious I got to work on finding ways to solve this problem.

I didn’t want this to be too complicated and take lots of effort, so I decided to keep things as simple as possible.

Funnily enough this was so simple and enjoyable I’ve made it part of my “debriefing” process after a hard stint.

  • Going to Bed When I’m tired
    Elsewhere in the blog I’ve stressed the point about going to bed at a regular time so that your body naturally starts to prepare for sleep without any conscious effort on your part. Apps like Pillow and Apple’s Sleep remind you to get to bed at a particular time. But sometimes I ain’t tired at a specific time so it becomes a bit of a chore.
    By going to bed when I’m really tired, I let my body and not the clock dictate when I should go to bed.
  • Waking Up After a Full Nights Sleep
    I like most have a morning routine that doesn’t allow for this one so much, but I’ve found that if I go to bed when I’m tired I naturally get roughly 7-8 hours sleep. So if I’m feeling tired between 10pm – 11pm I would wake up naturally between 6am and 8am.
    This has helped me get back into the flow quicker and I’ve felt that I’ve fell back into my usual sleep routine and feel much more alert faster than I’ve done in the past.
  • Cut Back on Napping
    Napping has been my latest productivity hack, so I was a bit reluctant to give it up in any way. But by reducing my napping to 10 minutes and only having a maximum of two a day whilst I was in recharging mode, helped me to feel naturally more tired earlier in the evening, which helped me to spend more time asleep and paying down my sleep debt.

Just remember that I did this during my down time from being busy. It’s a lot harder to do when you’re busy, so to get the best results plan accordingly.

Recap

So there you have it. Simple and effective and actually quite enjoyable once you get into the flow.

Since trying out this protocol my mood has picked up and I feel human again ?

The only hard thing about this is to use it during the relatively calmer periods of your life after you’ve had a very hectic prolonged schedule.

  • Go to bed when tired (our app V-CAF can help with that, it notifies you when you are tired and losing focus)
  • Waking Up After a Full Nights Sleep
  • Cut Back on Napping

Afterword

“A good laugh and a long sleep are the best cures in the doctor’s book.”

Are You Getting Enough?

Make Time For A Nap

The original power booster…

Tim was fed up. He’d been working long intense hours to meet his departments’ end of year deadlines. He also had been putting in extra time on his side hustle as a “gig” driver with an online company to help make ends meet.

Nothing seemed clear to him anymore. Whatever he tried to do to earn a little extra cash didn’t seem to be working. It seemed the harder he tried, the less things worked out for him.

“I just can’t think straight!”, said Tim. Each hour of each day for every week since March just seemed to blur into a weird blob of fuzzy consciousness.

Deprived

The fast pace of modern life is causing an ever increasing amount of people to not get enough sleep. Pulling all nighters to complete work or study deadlines as well as worries about their financial situation is causing many to feel stressed and fatigued.

As Tim was finding, being stressed and tired makes it more difficult to think clear enough to find solutions that work, which tends to imply that people are actually making things worse for themselves without realising.

The cost of the frantic pace of modern life is less productivity, a reduction in economic activity, and ultimately your health.

The Health Risks

Tim was displaying the classic early symptoms of sleep deprivation. These include:

  • Constant yawning.
  • A likelihood to fall asleep when inactive (for example falling asleep in a meeting or nodding off whilst driving).
  • Feeling fatigued all day.
  • Irritability.
  • And poor concentration.

More advanced sleep deprivation leads to more advanced symptoms :

  • Uncontrolled bursts of sleep.
  • A weakened immune system.
  • An increased possibility of being obese.
  • Tired drivers are 5 times more likely to have a crash.

Getting Enough

Like most people, Tim knew that he needed to get more sleep. But that wasn’t the problem. He needed a plan to be able to get the sleep that was healthy for him whilst being able to work and get things done.

I gave him some of the articles that I’ve written in the past as well as some one to one advice, but the key is to find what works for you and commit yourself to stick to it.

  • Sleep
    Create a sleep timetable for yourself. Make sure that you set realistic goals, for example most people need from between 6 to 10 hours of sleep (depending on age, weight and other factors), so make sure you take all the factors of your life into account. And make sure that you plan and actually go to bed at the same time every day, and wake up at the same time too.
  • Caffeine
    Again, each person is different. I gave up caffeine completely for a few years, but now use it in passing. If you are going to consume caffeine make sure you don’t have any between 4 to 8 hours before you go to bed. Caffeine can stay in your system for up to 15 hours, so again experiment and see what works for you.
  • Breaks
    Where possible, take regular breaks, especially if you are driving or operating heavy machinery. During your breaks try to have at least one 10 – 20 min nap to help refocus your mind. Our Apple Watch app V-CAF, is ideal for letting you know when your alertness is decreasing so that you can optimise your work and breaks to when your body really needs them.
  • Exercise
    Establish a regular exercise routine. Exercise is good for relieving stress and helps boost the quality of your sleep in the evening. It doesn’t have to involve joining a gym. A 20 minute brisk walk is good enough to help improve your blood circulation and the benefits to your sleep are immediate.

Recap

I benefited greatly from the above tips that I’ve outlined for you above, which is why whenever I get the chance to share that information (like I did with Tim), I leap at it.

But, it’s up to you to use them as just reading about them won’t change anything.

To recap:

  • Establish a regular sleep routine and stick to it
  • Reduce or cut out caffeine consumption
  • Take regular breaks whilst working
  • Exercise daily (even if it’s a 20 minute walk)

Afterword

“Fatigue will continue to impact productivity and the number of accidents at home and in the workplace. Sleep deprivation may be the next emerging health issue for both individuals and business.”

Power Napper?

Fast Recharge

Super Booster

You may have noticed that we are living in an age of abundance. Never before has it been so easy for people to pass information between each other at such great distances and across multiple timezones.

Depending on where you live there is an abundance of choices on the types of food, clothing and entertainment that you can consume. Even the choices that we can make regarding what we do to make a living have increased (although this too is also changing, but that’s another topic).

But this abundance comes at the cost of something that we humans have been taking for granted since the industrial revolution. Something that is so fundamental to our health and wellbeing that not getting enough of it can be disastrous to ourselves and those around us.

Devalued

Sleeps importance has been downplayed for a while now. Popular culture praises those that are willing to sacrifice their sleep in order to make it to the top.

Do a search in your favourite search engine to find “famous people who claim that they only sleep for four hours or less” to find endless results of people that “…all have one thing in common. They sleep less and are all successful in life.”, (an actual quote from one of the results I got back)!

The countless lists of CEOs of the biggest corporations that appear to devalue sleep is also reflected in books and articles detailing how they got to the top with little to no sleep.

Even CEOs of companies that apparently allow for their staff to be able to take a nap at work, don’t do that themselves.

 

Looking the Part

Not surprisingly those that do take a nap at work or nod off whilst working are seen as being lazy or not up to the task. Add to the fact that no one wants to be seen as the slacker, so will happily point to those that appear to be slacking off so as to look more favourable to the boss.

This attitude to tiredness is dangerous and especially so for those that operate heavy machinery or drive for long hours. In an attempt to make deadlines or quotas, people are putting their life and the lives of others at risk.

If you’re feeling tired at work or whilst studying and someone notices, you may have been offered a coffee or told to have a coffee break. Coffee, or caffeine may make you feel more alert in the short term, but you body is actually telling you that you need to stop.

Many of us feel tired in the afternoon, and that’s not just because we’ve had a big lunch. Our circadian cycle typically alerts us that we are starting to slow down and so sleepiness increases. But instead of listening to the warning we reach for a coffee or caffeinated beverages (or caffeine pills, chocolate), to perk ourselves up.

Reclaiming Ourselves

But there is an alternative; having a 10 to 20 minute nap. Instead of taking a coffee break, if possible, find somewhere quiet and take a nap. In the past I’ve used libraries, quiet coffee shops, or during the summer, a green space in a park, to take a nap.

Many researchers are now finding the benefits of a 10 to 20 minute nap may help boost productivity and possibly increase companies revenues.

“During an average work afternoon, a disproportion of the circadian alerting signal to the rising homeostatic sleep pressure occurs, resulting in increased sleepiness and reduced alertness. These factors, along with other impacted cognitive and emotional performance metrics, result in decreased productivity. There is a wealth of evidence that brief daytime naps of 10-20 minutes decrease subjective sleepiness, increase objective alertness, and improve cognitive performance. Daytime napping facilitates creative problem solving and logical reasoning, boosts the capacity for future learning, and consolidates memories. These benefits are not restricted to those experiencing sleep deprivation. Even in well-rested individuals, napping can enhance alertness, performance, and productivity for several hours. Daytime naps also allow for the regulation of emotions, relieve stress, and strengthen immune system function, reducing levels of the stress hormone norepinephrine and normalising levels of interleukin-6 an immune-regulating molecule. Taken together, allowing time to nap during the workday and reap the collective benefits will result in greater productivity and quality output rather than simply pushing through the fatigue, producing sub-standard work.”

Alger, S., Brager, A., Capaldi, V., & , (2019). Challenging the stigma of workplace napping. /SLEEP,/ /42(8),/

Review

I know it’s difficult to take a nap during the day whilst at work or studying, but there are ways around it. Like me, you can find places outside of work to take a nap. If not, then unfortunately it will have to be your car, or book a meeting room for 15 mins and put your head down on the desk.

If you want to boost your productivity then an afternoon nap is well worth it! Napping:

  • Decreases subjective sleepiness
  • Increases objective alertness
  • Improves cognitive performance
  • Facilitates creative problem solving and logical reasoning
  • Boosts the capacity for future learning
  • And enhances productivity for several hours

Afterword

Life is not all about productivity and study. You have to look after your health. Napping is valuable and a great protector of your health:

  • Daytime naps allow for the regulation of emotions
  • Relieve stress
  • Strengthens immune system functioning
  • Reduces levels of the stress hormone norepinephrine
  • And normalises levels of interleukin-6 an immune-regulating molecule

So Tired You Can’t Stay Awake?

Stay Awake, Stay Alert, Stay Focused

The V-CAF app Can Help…

A lot of people that I speak to complain about not having enough time to get things done. Work or study loads are excessive, home life is hectic and there is always something more to do.

“There just isn’t enough hours in a day to get everything done” is a common phrase around these parts. So what do we do? We lengthen the day by cramming more stuff into whatever time is left usually by staying up later and waking up earlier.

Sure in the short term it appears to work, but for many people this has become the norm, and there seems to be more people complaining about feeling tired and lethargic during the day.

Drowsiness

You don’t do it on purpose, but it sneaks up on you. Being so focussed on the overwhelming amount of tasks that you have to take care of, you get to work on completing what you can to the best of your ability.

More and more time is spent on doing “what needs to be done”, but you start to skip breaks. Perhaps you start eating at your desk or start increasing the amount of coffee and caffeinated sodas that you drink.

Longer hours become the norm. You have less time to switch off after finishing for the day and find it difficult to get to sleep, and when you wake up the next morning, you feel that you could sleep for another couple of hours easily.

Your days become a blur. You are becoming increasingly mentally and / or physically tired. It’s harder to think straight and your work tasks seems to be impossible to do.

 

The True Cost

Unwittingly you have been steadily increasing your sleep debt. It is difficult to notice and as a result very easy to make yourself very tired. Just loosing a couple of hours a sleep per night can have detrimental effects on your brain’s ability to accurately complete tasks and keep focussed.

The cost to your health isn’t good either. Building up a sleep deficiency over time can lead to:

  • An increase in obesity
  • Heart disease
  • High blood pressure
  • And negative affects on the quality of your life and relationships

And our collective tiredness costs the economy too.

“ Insomnia may be responsible for over $63 billion in absenteeism and presenteeism, and accidents and errors by people suffering from insomnia may result in an additional $31 billion lost annually. A recent report estimates that undiagnosed sleep apnea in the U.S. costs society $150 billion each year. The RAND Corporation has estimated that collectively, costs attributable to sleep deficiency in the U.S. exceeded $410 billion dollars in 2015, equivalent to 2.28% of gross domestic product.”

Calculating the Cost of Poor Sleep – Methodology, Nation Safety Council

Reducing the Debt

Fortunately, the fixes are relatively simple to implement, but they will take discipline to keep up so that you reap the full benefits of being alert and not feeling drowsy during the day.

  • Reduce or Avoid Caffeine
    Caffeine is a stimulant. If used correctly, it can help boost your alertness. But the problem is that it is addictive and people tend to drink too much caffeine. Too much caffeine inhibits your brain’s capability to know when you are tired, and as a result lead to a decrease in the quality of sleep that you get, which in the medium to long term will make you feel worse.
  • Get Enough Sleep and Take Naps
    Everyone is different so it’s difficult to stay exactly how much sleep you need. As a result, most health experts say between 7 to 9 hours sleep is what is needed for the typical adult.
    If possible, take a nap during the day (10-20 mins). Usually after lunch good. Taking a nap has been proven to be beneficial in helping people to concentrate.
  • Take Regular Breaks
    Schedule in breaks to give yourself time rest. The problem is that we can be so focussed on our work that we forget. Speaking for myself, I tend to get tunnel vision whilst working to the exclusion of everything else and as a result miss my breaks. But, since we created V-CAF, which I use daily, my Apple Watch and iPhone notify me as my alertness levels drop, which i then use as a signal to get up and away from my desk for a few minutes.
  • Daily Physical Activity
    A little exercise goes a long way. Just a 15 minute walk during the day helps to improve sleep quality when it’s time for bed. If possible, include exercise in your daily routine. But be sure not to exercise too close to bedtime.

Key Points

Drowsiness affects us all from time to time, but there are things that we can do to reduce it and keep it at a minimum. Try incorporating these tips into your daily routine to help you feel more alert.

  • Reduce or Avoid Caffeine
  • Get Enough Sleep and Take Naps
  • Take Regular Breaks
  • Daily Physical Activity

Afterword

Right now, we are all living through stressful times. Please take the time to look after yourself and try not to worry about what is going on out there in the world.

Focus on the things that you can control. Getting enough quality sleep alone helps to reduce bad moods and can make you feel better. Exercise can also help lift your mood and is good for your heart.

Control these things and you’ll be in a much better position to take on whatever the world throws your way.
