Eye-Opening Stats & Facts About Sleep (Infographic)

General Sleep Stats

1. You spend about a third of your life sleeping.

This is simple math if you assume that every person sleeps 8 hours a day on average.

(American Sleep Apnea Association)

2. Most healthy adults need at least 7 hours of sleep a night to feel rested.

Most people can’t perform at their peak without at least seven hours of sleep. However, more and more people are not getting the recommended minimum. Check out this infographic to find out how much sleep some of the famous people usually get.

(National Sleep Foundation)

3. 65% of Americans believe that adequate sleep boosts their effectiveness.

According to sleep statistics from 2018, people with higher incomes and college degrees often claim that they are more effective if they get adequate sleep.

(National Sleep Foundation)

4. 45% of Americans report that inadequate sleep affects their daily activities.

It’s no wonder that people with sleep problems can’t perform at their peak since lack of sleep impairs their ability to concentrate, leaving them feeling tired and unfocused.

(National Sleep Foundation)

5. Sleep is a top priority to only 1 in 10 Americans.

According to American sleep statistics, most people place physical fitness and nutrition in first place when prioritizing their personal activities and health needs.

(National Sleep Foundation)

6. Our sleep consists of 25% REM and 75% NREM sleep.

Our brains are most active during REM (rapid eye movement) sleep, and this is when we dream the most vividly.

(National Sleep Foundation)

7. 56% of vigorous exercisers report having a good night’s sleep almost every night.

Conversely, according to sleeping statistics, 47% of non-exercisers claim they rarely have a good night’s sleep. Therefore, we can conclude that exercising greatly improves our sleep.

(National Sleep Foundation)

8. Our body temperature decreases by 1°–2° during sleep.

A lower body temperature promotes sleep and helps us stay asleep. It increases a few hours before we wake up, preparing our body for a new day.

Sleep Disorders and the Statistics About Them

9. Between 50 and 70 million people in the US suffer from a chronic sleep disorder.

Considering the serious consequences sleep disorders can cause, this is something we should worry about. To list just some of them: they can lead to accidents and injuries, impair quality of life, reduce productivity, and increase healthcare costs.

(National Center for Biotechnology Information)

10. There are about 90 different sleep disorders.

Insomnia, disrupted breathing, and narcolepsy are among the most common ones. The most prevalent sleep disorder symptoms include problems with falling or remaining asleep, abnormal behaviors during sleep, and excessive drowsiness.

(National Center for Biotechnology Information)

Men are more likely to have this chronic disease than women. Sleep apnea may lead to some serious medical conditions, including Type 2 diabetes, high blood pressure, and stroke.

This makes insomnia the most prevalent sleep disorder. It’s followed by sleep apnea and narcolepsy.

14. Sleep Deprivation Statistics

It’s estimated that 68% of Americans, or 164 million, have sleep problems at least once a week.

This fact is based on a Consumer Reports survey that included 4,023 participants. According to this article, the major reason for having less sleep is that Americans work longer hours: 44 hours a week on average.

(Consumer Reports)

15. Approximately 35% of US adults get less than the recommended 7 hours of sleep per night.

If you sleep less than 7 hours a night, you have a higher risk of obesity. Besides the correlation between obesity and sleep, an inadequate night’s rest can also lead to diabetes, high blood pressure, and coronary heart disease, among other things. That’s why you should develop healthy sleep habits.

(Centers for Disease Control and Prevention)

16. 97% of surveyed teenagers reported sleeping less than what’s recommended.

Experts recommend that teens should sleep 8–10 hours each night.

(Scientific American)

17. As for college students, sleep statistics show that about 8 in 10 students believe that a lack of sleep affects their academic performance.

Some of the reasons college students don’t sleep enough include binge drinking, caffeine and energy drink consumption, and the use of technology before going to bed.

(National Center for Biotechnology Information)

18. 70% of college students don’t get enough sleep.

According to some confirmed lack of sleep statistics, sleep-deprived college students are more likely to have lower grade point averages. In addition, inadequate sleep and daytime sleepiness negatively affect their learning capabilities and mood.

(National Center for Biotechnology Information)

19. About 4% of surveyed adults fell asleep while driving in a single month.

Since drowsy driving can be extremely dangerous, it’s of immense importance to get enough sleep before taking the wheel. If you have a sleep disorder, you should get adequate treatment and not take any medications before driving that make you sleepy.

(Centers for Disease Control and Prevention)

20. In 2017, drowsy driving was responsible for 795 fatalities.

Based on the NHTSA sleep statistics, drowsy drivers participated in 90,000 car crashes in 2015. Therefore, you should follow some useful tips on staying alert while driving, such as getting a good night’s sleep before starting a trip and avoiding drinking alcohol prior to driving.

(National Highway Traffic Safety Administration)

Sleep Market Stats

21. Approximately 4% of Americans used prescription sleeping pills in a one-month period.

(Centers for Disease Control and Prevention)

22. The US “sleep market” was valued at $28.6 billion in 2017.

Considering how many people have sleep disorders, it’s no surprise there’s a great demand for medications and other sleep-related products that alleviate these problems. It’s expected that this market will have an average annual growth rate of 4.7% over the next few years.

(MarketResearch.com)

23. The CPAP device market is worth $4.3 billion.

Since obstructive sleep apnea is becoming more and more prevalent, this segment of the sleep market is also growing every year. However, its huge potential has yet to be tapped in the US.

(MarketResearch.com)

(Statista)

26. 62% of adolescents who participated in the NCBI study took their phones to bed.

A considerable number of them also used their phones for texting after “lights out.” This explains why so many adolescents have sleep problems, since the use of technology at bedtime has a negative effect on the quality and quantity of sleep. In fact, one of the most unhealthy sleeping habits is using a smartphone before sleep.

(National Center for Biotechnology Information)

27. 89% of surveyed parents have at least one electronic device in their bedroom.

According to this poll from a few years ago, most of them had a TV (62%), which was followed by a tablet or smartphone (45%).

(Loughborough University)

35. About 2% of Brits are satisfied with their sleep quality, waking up well-rested every morning.

It’s shocking that 26% of Brits never feel refreshed and well-rested in the morning, and about 50% of them only occasionally feel refreshed when they wake up. It’s interesting that the results varied greatly across the country: 85% of people from Sheffield don’t feel well-rested in the morning, while 31% of people from Bristol wake up refreshed.

(Loughborough University)

Fun Sleep Facts

36. People on average have 3–5 dreams each night.

Some people have up to seven dreams a night. Usually, we don’t remember most of our dreams, because we can only recall them if we wake up during the REM phase of sleep.

Let’s Sum Up

Juggling so many things at the same time—private life, career, family responsibilities—we tend to overlook the importance of sleep. More often than not, we sacrifice an hour or two of our precious night’s rest so we can fit all our daytime activities in.

However, inadequate sleep can have a number of serious negative effects on our health, mind, productivity, and focus. We hope that these sleep statistics compiled from a number of reliable sources will help you understand that having enough ZZZs is vital to your well-being.

Just one thing I need to clarify: Sleeping on your back can cause your tongue to fall into your throat. That is the mechanism of sleep apnea. Even IF the tongue becomes paralysed in this position, it falls forward, out of the throat. I always and can only sleep prone and have excellent quality of sleep. Why is the literature so persistently insistent about sleeping on your back? Look at your cats and dogs and horses and all sleep prone or at least semi prone.
