What time is best for children to go to bed at night?

Nowadays, many young parents are prone to late sleeping syndrome. If this situation is not handled in time, it will indirectly affect the baby's rest. Only with sufficient sleep can the baby develop and grow healthily. Otherwise, it will bring serious harm to the child, such as affecting the child's cardiovascular health, brain and learning, etc. So what time is the best time for children to go to bed at night?

First, what time is best for children to go to bed at night? Studies have shown that 70% of a child's height is determined by his parents' genes, and 30% is determined by acquired factors. Among these 30% external factors, sleep ranks first in its impact on height, surpassing exercise and diet. This is because growth hormone is secreted during sleep. Growth hormone is secreted by the pituitary gland. However, the pituitary gland has a heavy workload every day. In addition to secreting growth hormone, it also secretes sex hormones, adrenocorticotropic hormone and other hormones needed by the human body. Because it is "too busy", it does not secrete growth hormone 24 hours a day. The pituitary gland secretes growth hormone mainly at night. The more it secretes, the more it helps growth. The two periods when growth hormone is secreted the most are 21:00-1:00 and 5:00-7:00.

Second, growth hormone does not begin to be secreted in large quantities on time at 9 o'clock in the evening. Its large-scale secretion must have a prerequisite: it only occurs during deep sleep. People usually enter deep sleep half an hour to one hour after falling asleep. Therefore, if the child has not gone to bed at 9 o'clock, or has gone to bed but has not fallen asleep, or has fallen asleep but has not entered deep sleep, the secretion of growth hormone will be greatly reduced, thus affecting the maintenance of his height.

What time is best for children to go to bed at night? Children of different ages require different amounts of sleep, and the American Academy of Pediatrics has corresponding recommendations. Generally, American parents pay great attention to their children's sleep time and help them develop good sleeping habits from an early age, which is very beneficial to their physical development and future study and life. ”
