Rumor: the child can grow taller if he sleeps more? The key is that growth hormone does not look at the length of time

Regarding the growth of children, every parent is very attentive. Moreover, almost every parent will say a word to their children, that is: "Go to bed early at night, sleep more to grow taller." Then in order to let the children sleep more and go to bed early, parents are telling stories, singing children's songs, and Some of them simply help their children with their homework, and it's a frustrating heart. However, looking at many of our staying up late homework assignments, children of average height will also grow taller. Why is this?

It turned out that we misunderstood the relationship between sleep and growth hormone secretion, the key is that the growth hormone does not watch the length of sleep.

The amount of growth hormone secreted by the human body is higher at night than when awake

Many parents will notice that babies are particularly fond of sleeping when they are born. People around them, including doctors, will say "more babies sleep faster" and also say that babies "grow in sleep". Therefore, many people also associate "sleep" and "growth" in their cognition, thinking that children can grow taller if they sleep more.

In fact, the growth hormone secreted by children growing up 24 hours a day is different. Studies have shown that when people sleep at night, they secrete more than when they are awake. Because when sleeping at night, the child's spine, leg joints, etc. are in a relaxed state and can stretch freely, which is beneficial to the development of bones. Therefore, many parents will say that let the children sleep more to grow taller. But is this really the case?

Growth hormone is secreted more in deep sleep, no matter how much time you sleep

In fact, it is not that as long as the child sleeps for a long time, the secretion of growth hormone will definitely rise. According to a scientist observing changes in children's EEG during the 1950s, many experts have found that human sleep can be roughly divided into two states: one is light sleep; the other is deep sleep or deep sleep.

Studies have shown that the peak period of growth hormone secretion in the human body occurs during the deep sleep stage at night. If you fall asleep at 9 o'clock in the evening, you start to enter deep sleep at about 9:30 to 10 o'clock, and the peak of growth hormone secretion is from 10 o'clock to 2 o'clock in the morning. In other words, the premise for a child to grow taller is to enter deep sleep at a fixed time in the evening. Therefore, sleeping too much, sleeping during the day and sleeping at night, or even sleeping all day on weekends, is not helpful for increasing the amount of growth hormone.

Therefore, too much sleep does not necessarily make the child grow taller, it is possible to sleep well

After understanding that "children sleep more and grow taller" is a pseudo-proposition, we also have to figure out what sleep really means to grow taller. In fact, no matter whether you go to bed early or go to bed late, you must ensure the quality of your child's sleep so that she can smoothly enter deep sleep and not miss the peak period of growth hormone secretion. The quality of sleep is high, not intermittent sleep when pretending to sleep, light sleep, or insomnia. For example, some parents force their children to go to bed at 8 o'clock at night, but the children are very excited, and the quality of sleep is not high. As a result, it is awkward that they have not really fallen asleep in the middle of the night. If they miss the peak period of growth hormone secretion, this will be considered " "Sleeping more" does not necessarily make the child grow taller.

Therefore, only by improving the quality of sleep and letting the child sleep well can he effectively use the peak period of growth hormone to grow up. But remember, it's just possible. After all, the height of the child is also related to heredity, and the secretion of each child's own growth hormone may not be able to fully meet the needs of growth. Therefore, parents should not put their child's high hopes on sleep.
