The height of children is related to the secretion of growth hormone as well as to the factors of genetics, nutrition, and physical fitness.
Generally, growth hormone is generated when a person sleeps.
It begins to form most actively an hour or so after you fall into deep sleep and, in general, its secretion is in full vigor from 22:00 to 1:00 next day.
Therefore, regular sleeping is essential for the regular secretion of growth hormone.
Excessive oversleeping can interfere with the growth and development of children.
