A lot of what we know about sleep today has only been investigated in the last 30 years or so, and much of this research has proven that a good night’s sleep isn’t a luxury; it’s a necessity. As demonstrated by devastating events caused or influenced by sleep deprivation, like the Challenger explosion in 1986 or the Exxon-Valdez spill in 1989, not getting enough sleep can have serious consequences, both for individuals and for societies.
So, because sleep is so important for our health and wellbeing – it’s one of the four pillars of healthy living, together with exercise, good nutrition, and relaxation – we have compiled a list of the 30 most fascinating, intriguing, and insightful research-backed facts and statistics about this fantastic nighttime habit of ours.
Sleep Facts and Statistics
- Humans spend one-third of their lives sleeping.
- Americans sleep 6.8 hours daily on average.
- 35 percent of Americans don’t get the recommended seven hours of sleep each night.
- Lack of sleep is linked to several chronic conditions, like type 2 diabetes, depression, obesity, and heart disease.
- Falling asleep should take you 10 to 20 minutes. If it takes you less than five minutes to fall asleep, chances are you are sleep deprived.

- In a nation-wide sleep survey, nearly 38 percent of respondents reported unintentionally falling asleep during the day at least once during the previous month.
- Driving while sleepy or drowsy is similar to driving under the influence of alcohol. In fact, going 16 hours without sleep is the equivalent (reaction times, ability to sustain attention, awareness of hazards) of driving with a blood alcohol concentration of 0.08%, the US legal limit.
- According to the National Highway Traffic Safety Administration, there are about 100,000 police-reported car crashes every year that involve drowsy driving.
- People are three times more likely to be involved in a traffic accident if they are fatigued.
- Disrupted sleep is the most common sleep problem, with short-term sleepless issues reported by about 30 percent of US adults.

- The percentage of disrupted sleep instances increases with age, with 50 to 70 percent of older adults reporting difficulties sleeping at night.
