How long do you sleep in a day, and the scientific amount of sleep is how many hours

Generally speaking, the best sleep time for people of different ages is different, newborns need to sleep 20 hours a day, babies sleep 14 hours to 15 hours, preschool children sleep 12 hours a day, primary school students need to sleep 10 hours, middle school students need to sleep 9 hours, college students only need to sleep 8 hours, adults need to sleep 8 hours, and the elderly need to sleep 6 to 7 hours a day. Sleeping too long or too little is bad, so you should pay attention to the best time to sleep.

Everyone's sleep time is different, the average person is 8 hours, it is best to sleep in different days, compared to 7 hours at night and 1 hour at noon. It is related to the fact that if a person is very happy, his sleep quality is high, even if he sleeps a little less, he will not be sleepy, on the contrary, if a person is in a bad mood, very troubled, and sometimes sleepy for a few more hours and still sleepy, please keep a happy mood.

6-10 hours of sleep a day is appropriate, and the exact time needs to vary from person to person.

Sleep is an indispensable physiological phenomenon of the human body, about 1 3 times in a person's life in the state of sleep, sleep quality and human health have a close relationship. Adequate and high-quality sleep helps to restore mental and physical strength, can relieve visual fatigue, prevent the occurrence of vision loss, and also help to enhance the body's immunity.

Because each person's sleeping habits and sleeping environment are different, there are individual differences in the amount of sleep time per day, and the daily sleep time of minors is usually controlled at about 8 to 10 hours; Young and middle-aged people usually sleep 7 to 8 hours a day; The sleep time of the elderly will be relatively reduced, and the sleep time will also decrease, generally about 6 hours. Usually, if you wake up after sleep, if you feel comfortable, energetic, energetic, focused, etc., it means that the body and brain have been fully rested, then the sleep time is generally more appropriate.

From a health point of view, sleeping for four hours is not good for your health. The latest research has found that adults should sleep a little more than 7 hours, which is the most suitable for the human body and is beneficial for longevity. It is generally believed that more than 80% of adults sleep for about hours a day, teenagers need more, teenagers need about 8-9 hours, and children need more, children need 10 hours of sleep.

But this is only for most people, there are individual differences. Some people take short sleeps and only need 4-5 hours of sleep every night. These 4-5 hours of sleep will not cause any physical discomfort to these people, so there is no need to force 6-7 hours, or 7-8 hours of sleep, so that they will feel uncomfortable.

Some adults may need to sleep for a longer period of time, perhaps 9-10 hours. This is a long sleeper, accounting for about 1%-3% of the population. So how long you sleep depends mainly on whether you can sleep well, and you can be clear during the day, and you don't feel tired or sleepy, so you don't have to worry too much about how long you have to sleep.

Normal sleep time is different for different ages. Newborns sleep 20-22 hours, 2-20 hours for babies around 2 months, 15 hours at 1 year old, 14 hours at 2 years old, 13 hours at 3-4 years old, 12 hours at 5-7 years old, 10 hours at 8-12 years old, and 9 hours at 12-18 years old. It takes 7-8 hours for adults, 9 hours for 60-70 years and 10 hours for 70-90 years.

The most reasonable sleep time every day is generally about seven or eight hours, which can fully give us a relaxing time and can also allow us to have the effect of prolonging life. But if we sleep for more than seven or eight hours, it will affect our physical health, and it will also cause our body to become particularly decadent.

Generally speaking, people's normal sleep time is 7 and a half hours, with a minimum of 6 and a half hours, but there are exceptions, as long as they feel that they have slept enough and have enough energy.

Human sleep is related to the secretion of melatonin and the body's core body temperature. Generally speaking, the body temperature reaches its highest at 7 o'clock in the evening, and then it begins to fall, at 9 o'clock melatonin begins to secrete, and at 10 o'clock half the intestinal peristalsis is inhibited, in other words, the period from melatonin secretion to intestinal peristalsis inhibition is the time to start sleeping. Between 2 and 4 a.m. is the deepest sleep, and this is also the time when you are most likely to doze off.
