20 minutes, not more than half an hour, this is appropriate.

The need for sleep varies at different stages of a person's life, with primary school students needing about 10 hours. In short, as we age, we need less time to sleep.

If a child does not get enough sleep, the more reliable measure is whether he is full of energy after waking up the next day, whether he can maintain strong energy in class during the day, and whether the annual growth rate reaches more than 5 cm. If your child meets all of the above criteria, even if he sleeps less than a few hours a day, it is not a big problem. On the contrary, children who sleep for more than 10 hours a day but are still groggy should investigate the causes that affect the quality of sleep, to see if there are sleep disorders, or whether there are obvious external environmental disturbances, such as whether the father who likes to stay up late will affect the child's unstable sleep.

In order to recover physical strength and exertion and promote the physical and mental growth and development of children, it is necessary to ensure sleep time.

As we all know, students staying up late at night and not getting enough sleep will affect the next day's learning and affect the growth and development of teenagers, so if teenagers want to develop well and grow taller, they must get enough sleep.

Elementary school students between the ages of 10 and 13 should sleep for about 10 hours, middle school students between the ages of 14 and 17 should sleep for about 9 hours, and adults over the age of 18 should sleep for about 8 hours.

As for the sleep time recommendation for primary school students: primary school students should sleep no less than 10 hours a day.

The sleep time required for the above different ages is not absolute, such as patients or people who have not recovered soon, the sleep time needs to be longer, and the higher the quality of sleep, the better than the effect of long-term light sleep.

For example, some people sleep more than ten hours a day, but they still feel low energy and work efficiency; And some people sleep only 4 to 5 hours a day and are still energetic and working well.
