What time does the human body secrete growth hormone?

Human growth hormone is secreted in a pulsatile manner 24 hours a day.
The pituitary gland secretes growth hormone to help us regulate protein, sugar and fat metabolism and promote growth and development. Growth hormone is secreted from the pituitary gland in a pulsatile manner 24 hours a day, with a peak every 3-5 hours. In addition, the amount of growth hormone secreted during the daytime is relatively small, while the amount secreted during the nighttime is high, and the secretion peaks one hour after entering into a deep sleep, and the amount secreted is more than half of the total amount of growth hormone secreted during the day.
Many endocrine hormones in the human body show circadian secretion rhythm, growth hormone is mainly secreted at night, daytime secretion is less, the night secretion of growth hormone is about 2 to 3 times the daytime. The secretion of growth hormone increases gradually after 9:00 p.m. to 1:00 a.m., which is the peak of growth hormone secretion.
Sleep also affects the secretion of growth hormone, the secretion of growth hormone in 1 hour of deep sleep is about half of the total amount of the day. Therefore, children or teenagers should go to sleep before 9 o’clock to promote growth and development, long-term stay up late may affect the growth and development of children, height and so on may be affected. Usually you can also eat more food to promote bone development, such as milk, eggs and so on.
For more information about growth hormone, you can consult an endocrinologist and go to the hospital for further treatment if you have growth hormone abnormalities.
