Humans spend an average of 25 years of their lives asleep; this is one-third of our lives. That’s why you need to know more about sleep.
Sleep rate in developed countries
Research shows that adults need at least 7 hours of sleep a night to function effectively during the day, while only 21% of Americans sleep 7 to 8 hours a night, compared to the French population. They sleep an average of 8.83 hours a day and are the best country to sleep in developed countries. However, some people last less than possible; in fact, 1 to 3% of people are called “sleep-deprived” because they need less than six hours of sleep a night.
During the night, we go through five different stages of sleep. The first four eye movement stages are not fast when the body begins to rest and is ready to relax. Stages 3 and 4 seem to be the deepest stages of sleep as the body starts to recover. The fifth stage of sleep is rapid eye movement when the brain is active and is often asleep.
REM sleep is thought to occur every 90 minutes during the night.
You spend about 75% of the night in NREM sleep.
During sleep, the chemical elements in REM sleep paralyze the brain and muscles and wake you up.
Newborns have twice as much REM sleep as adults. However, children do not become paralyzed like adults because this part of the brain is not yet fully developed, so children often make irregular sleep movements.
Interesting secrets and facts about sleep:
