Yes, I do it every day. It's been 3 years.

People who sleep 4 hours a day have the possibility of sudden death. Because sleep is very important to people's health, the sleep time of normal people is 6-8 hours, if there is less sleep, long-term lack of sleep will cause the body's biological clock disorder, the decline of resistance, endocrine disorders, metabolic disorders, and also prone to cardiovascular and cerebrovascular diseases, and sudden death may occur. In addition, long-term staying up late and lack of sleep can also cause memory loss, neurasthenia, indigestion, and progeria.

Therefore, people who are sleep deprived should adjust the time of work and rest, maintain enough sleep, and if they do not sleep well, they can take appropriate drugs to calm and sleep. For the age of 19, it is far from enough to sleep only 4 hours a day, for this age group, the sleep time is at least 7 hours or more, generally 7-9 hours, your current judgment and other preliminary considerations may be caused by lack of sleep, so first of all, it is recommended that you maintain enough sleep to see. Normally, you should sleep enough for about eight hours a day, if you sleep four hours a day, severe lack of sleep, there will be physical exhaustion, fatigue, dizziness and headache, and in severe cases, it will also lead to damage to other organs of the body, first of all, you must pay attention to rest, it is best to sleep for eight hours, and you can cooperate with acupuncture to improve the current symptoms, and you can also do hyperbaric oxygen.

From a health point of view, sleeping four hours a day is definitely not a no-go. This sleep time is a bit too little. And it is also necessary to determine the amount of sleep according to the age of the person.

I think young people should sleep at least about eight hours. And the elderly over 60 years old. It should also be around six hours.

Sleep for. For anyone, I think it's a good way to stay healthy. Let all the organs of the body and the brain get a certain rest.

If always sleep only four hours a day. For a long time, it may be detrimental to the health of the body.

In reality, everyone's situation may be different. Well, it is true that some people may sleep less, and he can accept it. There will be no health problems in the body.

But I think for most people. Sleep should still be around six to eight hours. Only the body and brain are well rested.

In this way, I think that the next day's work may also be affected.

I'm not sleep-deprived. I have a deep understanding. That's when I got hooked on games.

Playing games every day is basically played all night. Sleep on your stomach in an internet café for a while. Get up and keep fighting.

Played for a while, later. I really feel like I'm gone. Groomy all day.

The mind is not clear. The idea of playing the game is messed up. The next day's work.

Don't mention it. It's even more difficult to do. Because I have to work during the day and play games at night.

The amount of sleep is very small, that is, a few hours. It lasts for about a month. It feels like the whole person has no energy.

Return to your normal schedule. You'll be better after a while, so anyway, I think? Four hours of sleep a day is really not good.

A little too little. For the sake of health, we still need to ensure that we get enough sleep.

It is said that there is such a person in the world who can be full of energy, move normally and have an active brain after only 4 hours of sleep a day, and I really envy my real name!

It is said that most people in the world need 6-8 hours of sleep a day, and if you can't get enough sleep, it will have a big impact on your attention and memory.

So you can try to sleep only 4 hours to see if you feel uncomfortable, if you don't and feel very necessary to sleep only 4 hours a day, ......Let's consult a doctor, this touches on my blind spot

If you feel unwell, it is recommended to maintain your daily routine, after all, life is still important. If you have to spend more time doing other things, you can try to be more efficient A study of nearly one million people over the age of 30 found that people who regularly slept less than four hours a day were three times more likely to die within six years than those who slept seven or eight hours a day.

2. A 1983 study conducted by the Naval College of Health Sciences in San Diego found that people who slept 5 to 7 hours a day performed worse in all performance evaluation measures than those who slept more than 7 hours a day. Overall, people who don't sleep well get fewer promotions in their careers, lower pay grades, are less likely to be recommended to work longer periods, have higher turnover rates, and are more likely to be hospitalized in the course of work.

One study found that women who slept an average of five hours a night were 39 percent more likely to develop heart disease than those who slept eight hours a night.

Another study found that men who slept only four hours a night in two chains had changes in their hormone levels, especially a decrease in leptin and an increase in ghrelin, which made them feel hungry and want to eat carbohydrate-rich foods such as cakes, candy, ice cream and pizza. Researchers believe that frequent sleep deprivation is associated with obesity. One final thing I would like to say:

It is true that a small number of people only need 4-5 hours a day, but most people feel this way, which is embarrassing. And there's no way to train our body to reduce its own sleep needs. I think you should shorten your sleep time because you want to have more time to work or study, but Einstein should sleep at least 10 hours a day, which means that your work achievements or academic performance may not have anything to do with the length of sleep, but after enough sleep, your attention and willpower will be better, and you can better complete the tasks you want to accomplish.
