The secretion of growth hormone in babies usually occurs in two time periods, between 21:00 and 1:00, and between 5:00 and 7:00 in the morning.
Most of the growth hormone secretion is pulsatile, and most of them will peak every 2~3 hours. The secretion will increase after sleep, and there is also a greater correlation with deep sleep, which peaks relatively in stage III or IV sleep.
Newborn babies serum GH level is high, the secretion of the rhythm is not mature, 2 ~ 3 weeks after birth serum GH concentration began to decline, two months after birth will form the secretion of the rhythm of GH daily secretion in childhood than adults, with puberty development secretion will be more obvious.
Usually babies at night at 21:00 will become a gradual secretion of the state, usually in the evening around 21:00 began to secrete growth hormone, in the deep sleep, 11:00 to 1:00 will enter the peak of growth hormone secretion. The secretion of growth hormone is usually accompanied by growth hormone in the morning after 5:00 a.m. It is necessary to avoid waking up the baby before 7:00 a.m. to avoid the secretion of growth hormone being affected.
Growth hormone for growth and development can achieve the role of promotion, if frequently disturbed during sleep, affecting the secretion of growth hormone, so that the body lack of growth hormone secretion, will generally lead to growth retardation, so you need to provide a good night’s sleep, to promote growth and development.
