Have you ever seen the following topic:

Going to bed late can affect a child's growth because growth hormone is one of the important factors affecting height.

The two time periods of 21:00-01:00 in the evening and 5:00-7:00 in the morning are the peak periods for growth hormone secretion.

If you miss these two peak periods, your child won't grow taller.

In this regard, a parent on Weibo asked about the soul: Is growth hormone secreted by pinching?

As a result, there have been some controversies over the secretion of growth hormone, and different doctors have different opinions.

Some people think that growth hormone secretion has nothing to do with the time to fall asleep, and some believe that the peak of growth hormone is in the above two golden stages.

In fact, before I saw this topic, I also thought that the peak of growth hormone secretion was in a fixed period of time.

In addition, my son has never slept late, no matter how or when growth hormone is secreted, he will definitely not miss it, so I haven't looked into this issue carefully.

But now that I find that there may be errors in my knowledge points, as an infant sleep consultant, I naturally have to figure this matter out.

About the secretion of growth hormone, listen to what the popular science doctors have to say

I consulted several articles and videos of popular science doctors who are familiar to everyone to see how they explain the law of growth hormone secretion.

1. Australian Maternal and Child Dr. Han

Original: There is no high-quality evidence to support the claim that there are two periods of the most growth hormone secretion, and it is true that some very preliminary studies have found that growth hormone is secreted more at certain times after falling asleep, and relatively less secretion at other times.

However, the findings of these preliminary studies can only stay in the study sample, and should not be directly extended and applied to all children and all populations, and it is directly believed that sleeping during the peak phase of growth hormone secretion can grow taller.

2. Pediatrician Kong Lingkai

Original text: Most of the growth hormone is secreted after falling asleep, and it generally reaches its peak about 1-2 hours after falling asleep, and the secretion amount is about 3 times that of the day.

3. Pediatrician Cui Yutao

Original text: The amount of growth hormone secretion is mainly related to sleep quality (deep sleep) and sleep duration, and it is not directly related to the time of falling asleep.

4. Pediatrician Pei Honggang

Original text: The secretion of strong pulses of growth hormone is related to sleep, and the pattern of strong pulse secretion is indeed related to the way of day and night, but it is not secreted at the pinching point, and no matter how it is secreted, the total amount of secretion in a day is unchanged, we should encourage the daily routine to work and rest, and ensure sufficient sleep time, but there is no need to worry about affecting the growth of height because the child sleeps a little later.

The above celebrities all believe that the secretion of growth hormone is not such a golden period as 21:00-01:00 and 05:00-07:00.

The time to fall asleep does not directly affect the secretion of growth hormone and the growth of height, but the key factors are adequate sleep and sleep quality.

5. Pan Hui, Peking Union Medical College Hospital

This doctor is the attending doctor of the short clinic of an authoritative hospital, and his area of expertise is the management of children's height.

I also purchased his video course "Compulsory Courses for Children Aged 3-7 to Grow Taller".

In the course, Pan Hui believes that there are two peaks in growth hormone:

The highest peak is between 21:00-01:00, and the small peak is between 05:00-07:00.

Make sure your child falls into deep sleep during these two times.

Seeing this, I was a little confused, who should I listen to?

I suddenly remembered my friend who was far away in Xinjiang and in the sixth eastern region.

If it is divided according to this time period, the children in her family who fall asleep between 23:00 and 00:00 every day will never be able to catch up with the first golden time of growth hormone secretion?

Is Dr. Pan Hui's division reasonable? I think it's reasonable to look at it from another angle.

Because according to the development chart of children's sleep stages, children who fall asleep around 20:00 are in the deep sleep stage during the two time periods of 21:00-01:00 and 05:00-07:00.

Growth hormone can only reach its highest secretion in the deep sleep stage, which is actually what other doctors call "reaching the peak secretion period 1-2 hours after falling asleep", which is not in essence conflicting.

In addition, growth hormone is affected by circadian rhythm, and the child's work and rest time should conform to the circadian rhythm, normal and regular, from this point of view, the above stage division is also reasonable.

For a child who falls asleep at 23:00, his entire sleep cycle is postponed, and the first peak of growth hormone occurs after 00:00.

As long as he can get enough sleep and sleep enough for his age, the peak period will not be missed.

To sum up, sufficient total sleep, high quality of deep sleep, and regular work and rest are important factors affecting the secretion of growth hormone, rather than simply the morning and evening of falling asleep.

In this case, don't we need to interfere with the matter of children going to bed late?

Not.

There are 2 consequences of sleeping that night, which will still affect the child's height

Although experts have refuted the rumors, the time to fall asleep does not directly affect the secretion of growth hormone, and there is no such thing as pinching it during its peak.

It seems to be a burden on children who go to bed late, but if sleeping late brings the following two consequences, it will still affect the secretion of growth hormone.

1. Children who sleep late are prone to be in a state of excessive tiredness and wake up frequently at night, resulting in low sleep quality

The peak of growth hormone secretion is in the high-quality deep sleep stage, what if the deep sleep stage is not of high quality?

Children who are excessively tired are prone to night terrors and crying 1-2 hours after bedtime.

When you wake up crying when you should be in a deep sleep, the quality of sleep is not high, which will naturally affect the secretion of growth hormone.

This condition is very easy to appear in children before the age of 3, if the child does not nap enough during the day, and then drags on until late at night, the accumulated sleep balance pressure is too large, and there will be a situation of not sleeping well at night and waking up frequently.

Even if you give your child a drink at five or six o'clock in the morning and let him sleep in the cage, try to sleep long enough.

But the time is enough, but the quality is not high.

Therefore, from the perspective of sleep quality, going to bed late will cause some drawbacks, which in turn will directly affect the secretion of growth hormone.

Of course, if your child goes to bed late, but has enough sleep duration and good sleep quality, as long as the parents can stay up, there is really no need to be anxious.

2. Children who sleep late are prone to lack of sleep duration

Before going to school, whether children go to bed late and wake up early, go to bed late and wake up late, parents always have a way to let their children make up for a full day's sleep.

But what about after school? The time for children to get up early is fixed, that is the point, and it is impossible to get a good night's sleep.

Under the premise that the time to wake up in the morning is limited, going to bed late will inevitably lead to insufficient sleep duration.

Adequate sleep duration is an important condition that affects the secretion of growth hormone.

The figure below is the recommended sleep duration for children of all ages published by the American Sleep Foundation, and we take the age group of 3-5 years old as an example.

The recommended optimal amount of sleep in a day for this age group is 10-13 hours, with a maximum of 14 hours and a minimum of 8 hours.

Suppose a kindergarten child wakes up at 7 a.m. but falls asleep at 11 p.m., and the night's sleep is only 8 hours.

The nap time in kindergarten is generally 2 hours, but children cannot fall asleep as soon as they go to bed, and 1.5 hours of sleep is considered good, so the total day's sleep may not be enough.

Therefore, from the perspective of sleep duration, the disadvantages of going to bed late are also obvious.

To sum up, sleeping late affects the child's height, not because of growth hormone pinching secretion.

Rather, it will shorten the total duration of sleep and reduce the quality of sleep, thereby affecting the normal secretion of growth hormone.

Parents who are struggling with whether their children who go to bed late will miss the peak of growth hormone may be disappointed if they find a reasonable explanation for their children to sleep late.

How tall a child can grow, it can be said that "seven points of heaven is destined, three points depend on hard work", genetic height is important, but the acquired "three points of effort" should not be underestimated.

These three efforts are: getting enough quality sleep, eating a nutritious and well-rounded diet, and exercising consistently.

Grasp these three points, height counterattack is not a dream.
