Is it enough for people to sleep for five hours, is it enough to sleep only five hours a day?

The length of sleep is the length of time that the human brain inhibits excitement, and the neural activity of the human brain is inhibited, making the person feel tired, which is about to want to sleep, and the length of the inhibition time [sleep time] is determined by age. Newborn babies [within three months] sleep about 20 hours a day, children around three years old, sleep about 12 hours a day, children between eight and twelve years old, sleep about 10 hours a day, teenagers between thirteen and sixteen, sleep about 9 hours a day, adults over 17 years old, sleep about 8 hours a day, and as they grow younger, sleep a little shorter every day, and people over 60 years old, sleep about 6 hours a day, for people over eighty years old, 5 hours of sleep a day is enough. But not for everyone, some people have a big difference, more than 20 years ago, a leader of my unit [the first leader, a department-level cadre] is about forty years old, only sleeps 3 hours a day, and can't sleep at other times, playing cards, watching **, watching TV, for many years, my mother-in-law is nearly 90 years old, and she sleeps more than 8 hours a day, these are special cases.

Sleeping too long or too little beyond the normal hours is harmful to a person's health.

Not enough, even mentally or physically, not less than 7 hours.

The normal work and rest time of people is 7 hours!

It's okay for adults, but it's best for six hours.

It is not enough to sleep only 5 hours a day, normal adults need to ensure 8 hours of sleep a day in order to relax the body, but also to speed up the detoxification of the body, 5 hours a day is a serious lack of sleep.

Lack of sleep may cause brain cell damage, and it will also be accompanied by symptoms of memory loss and immunity, so it is best to develop a regular routine to adjust it to reduce physical damage.

In fact, if it is a few times a few times, and it is a deep sleep, five hours is no problem. As long as it doesn't sleep for five hours for a long time, and the quality is not good, there is no problem at all.

In general, it is best to have 7-8 hours of sleep per day. Getting enough sleep is great for our health.

1) Lack of sleep affects the body's metabolism, our appetite decreases, and the speed of gastrointestinal peristalsis slows down, resulting in constipation, acne, bad breath, irritability and other symptoms.

2) Lack of sleep can also affect our endocrine system, and for women, it can lead to menstrual irregularities.

3) Lack of sleep affects our immune system, and our immunity will decrease, so that the ability to resist harmful substances from the outside world will decrease, which will increase our chance of getting sick.

4) In the long run, we are in a state of exhaustion every day due to lack of sleep, and the efficiency of doing things is not high, and the results are naturally not ideal. In addition, our weight does not become lighter because we look haggard, but rather increases.

5) Of course, there are two sides to everything, and sleeping too much is not too good. Studies have shown that sleeping too much may lead to an earlier age of Alzheimer's disease.

Finally, our so-called daily sleep time cannot be completely rigid according to the regulations, if we sleep 8 hours a day, but the quality of sleep is not high, when we wake up, we are still groggy, then it is meaningless; On the other hand, if I sleep 5 hours a day, but when I wake up, I feel as energetic and energetic as I can, then I am of high quality, which is far better than 8 hours of sleep.
