Recently, I have been completely fascinated by a book. Day and night, I finally finished it.
The title of the book is “Why We Sleep”.
It seems very boring and dull to read the title of the book, but once you open it, you will never let it go.
Today, I would like to introduce you to the wonderful science in the book.
The author of “Why We Sleep” is a sleep expert named Matthew Waler, a former professor at Harvard Medical School and now a Berkeley professor. University professor of psychology and neuroscience.
The beginning of the book is as follows:
Scientists have discovered a revolutionary new secret that could allow you to extend your life.

You will feel happier, less depressed, less nervous. Are you interested?
Professor Walker said: This can cure all diseases, not Hermes, but “sleep”.
Speaking of sleep, there is no one around me and I who is not bothered by it.
Moreover, in today’s society, almost 200% of the people do not sleep well at night and are very tired during the day (including the legend that every night President Obama who only slept 4 hours).
After reading this book, I realized that the problems caused by poor sleep at night are definitely not just being tired during the day, but also It is a very, very scary variety of mental retardation, physical disease, psychological disorder, character defect, and even life-threatening.
The key point is that these conclusions are not made out of thin air, but are drawn through countless scientific experiments for more than 20 years.
Let’s share some views and share with you – —
01, The most important thing in sleep is NREM (deep without blinking) Sleep, the main function is to improve physical fitness and immunity) and REM (rapid eye movement dreaming sleep, the main function is to improve brain function), these two determine the quality of sleep. It can also be said that children who sleep and love to dream are smart!
02、As long as you sleep less than 5 hours a night, the immune Natural Killer cells in the body that specifically deal with cancer cells will be reduced by 70%!

If a person is deprived of sleep, or food, or 24 hours of exercise, sleep damage the most.
05, people over 5 years old sleep less than 6 hours per night , 200% more likely than people who slept 7-8 hours to get myocardial infarction and cerebral infarction.
06, lack of sleep will make you stupid ( Because REM deficiency affects the health of brain cells), it is easy to get Alzheimer’s disease.
Margaret Thatcher and President Reagan are both known Those who sleep only 4-5 hours a day have Alzheimer’s disease. Walker predicts that the next dementia patient may be President Trump.
07, If you don’t sleep for 19 consecutive hours, your brain will lose Same with physical state and drunkenness.

08, Drinking coffee is equivalent to taking it to sleep Insufficient drugs.
If you are addicted and must drink coffee, then only Can drink before 1pm.
09, Alcohol not only does not Helps sleep, and affects sleep.
Alcohol (even a little) kills REM Sleep keeps us from dreaming.
10, Part of the reason for our poor sleep at night is the central heating And the constant temperature environment of the central air conditioner goes against the natural law of sleep needs.
11, Alarm clocks affect heart health, especially It is the kind of Snooze function alarm clock that will be called every five minutes, which puts the heart under 3-4 pressures in a short period of time, and has a great impact on the cardiovascular system for a long time.
12, summer time (time adjustment an hour earlier) is a very stupid system. Myocardial infarctions, car accidents, etc. all increased dramatically on the day the summer holiday started, because people slept an hour less.
13, Lack of sleep affects sexual function.
Men who sleep less than 5 hours per night, Compared with men who slept for more than 8 hours, the testicles are significantly smaller, and the concentration of testosterone in the blood drops to the level after ten years. Women who lack sleep are prone to infertility or miscarriage.
