Everybody knows that without sleep, we get cranky, a little crazy, and then we die. Unfortunately, the science was a little ignorant; although we understood the negative effects associated with lack of sleep, no one really knew why these things happened. Now, finally, we have an insight into what sleep face for our bodies.
- - 2/3 of adults in developed countries do not sleep the 8 hours per night recommended by the World Health Organization.
- - an adult who sleeps 6.75 hours a night is likely to live to age 60 if he does not have medical intervention.
- - men who sleep poorly reduced sperm quality by up to 29%.
- - If you drive and have slept less than 5 hours, you have a chance of an accident of 4.3, and if you have slept only 4 hours, your chances are up to 11.5.
- - a warm bath helps you sleep not because you get warmer, but because your blood vessels dilate and give off inner heat as your body temperature drops. To sleep well, the basic body temperature should drop to 1 degree.
- - 40% of the population wakes up in the morning, while 30% prefer to sleep late and wake up late. The remaining 30% are somewhere in the middle.
