How many hours of sleep a day How many hours a day do you sleep at least?

It varies from person to person, but unless you are really an extraordinary person, it is recommended not less than 8 hours, no less than 6 hours, this is the bottom money... There are classmates above who say that young people love to play.,So 8 hours is unrealistic.,I think it's a very irresponsible attitude to yourself.,I suggest you don't study.。。。

8 hours, 23 24 1 o'clock sleep must be guaranteed, this time seems to be bone marrow hematopoietic liver cell growth.

7 hours, I remember reading it on the Internet, saying that it is a scientific study that says that 7 hours of sleep is the longest life.

In my opinion, at least 6 hours a day, 8 hours is unrealistic for young people nowadays, because they all love to play, but I don't feel good for my body if I don't have 6 hours less, so I have to have at least 6!

7-8 hours, best before 11 p.m.

Adults sleep 8 hours a day, and children aged 6-13 years sleep 8-10 hours appropriately. As we age, we get less sleepy, and many older people get enough sleep for 6 hours. Sleep time varies from person to person, so it's better to stay energized during the day.

In addition, the daily sleep time of adults varies greatly due to work and lifestyle habits, which fluctuates around 5-8 hours. While most people may get 7-8 hours of sleep, some people need 8-9 hours or more of sleep to feel sufficient, while others get comparatively less sleep and 4-5 hours of sleep feel sufficient. At this time, it should be judged according to the situation of waking up the next day, if you feel full of energy after waking up, no longer sleepy, and can concentrate on your work and life during the day, it proves that your brain and body have been rested enough at night, and the sleep time of the previous night can meet your needs.

If you wake up with headaches, sore eyes, and low energy, it means that you haven't rested well. If you feel dizzy after thinking about it, although you are not sleepy but you are not motivated, it means that you have slept too much, and you can get up early appropriately.

In general, more than 8 hours is best.

Generally, adults can maintain a sleep time of about 8 hours, but there is no mandatory requirement for sleep time every day, and it is generally based on their own situation. As long as you are in a good state of mind the next day, you will get enough sleep according to your needs.

People of all ages need different amounts of sleep. Generally, newborns sleep for about 18 hours; Babies are about 12 hours; Preschoolers sleep for about 10 hours; Adolescents sleep for 8-9 hours; 7-8 hours for adults; Older people may have their sleep reduced to about 6 hours due to various functional declines.

People with sleep disorders can drink a glass of warm milk before going to bed, and do appropriate physical exercise during the day to help them fall asleep, improve sleep quality, and ensure that the brain is fully rested.

With enough sleep, nerve cells and memory cells are likely to play their best role. If you don't get enough sleep for a long time and have poor sleep quality, it is easy to cause various health problems, such as mental weakness, sleepiness, malnutrition, etc. Therefore, in order to ensure good health and maintain high efficiency in daily work and study, adequate sleep time should be ensured.

Recently, Mr. Zhang Chaoyang, CEO of Sohu, publicly said that ordinary people do not need to sleep for a long time every day, and it is enough to sleep 4 hours a day.

This sleep pattern varies from person to person and is not desirable for everyone!

Some people at the expense of sleep time, lack of energy, the efficiency of the whole day will be very low, sleep more and sleep less need to conform to the human body's sleep rules, only sleep well, energy, the efficiency is naturally high, no need to compress time to complete things.

Moreover, people have different needs for sleep duration at different ages, from the need for a longer sleep time when they are young to a shorter sleep time as they get older. But even for the elderly, 2-5 hours of sleep is clearly insufficient. When you sleep less than 6 hours, the risk of cognitive impairment is significantly increased.

Nowadays, young people have high work pressure, many entertainment projects, and lack of time has become the norm, which may also be the reason why various short sleep methods on the Internet have attracted attention. Reducing sleep time comes at the cost of health damage, and saving time really doesn't outweigh the cost.

On top of that, while we often see some well-known business people, historical figures, and other celebrities claiming to sleep only 4 hours a night, these claims are often unsubstantiated, and if you look closely, you will find them untrue.

Chances are, many people who say they don't need a lot of sleep will take naps during the day to compensate for the short nights.

So, we don't have to follow the trend and compress our sleep time!

As long as the average adult ensures that he goes to bed before 11 o'clock and gets 7-9 hours of sleep a day, he or she can achieve the best state of sensory and physical function.
