The secretion of growth hormone in the body is cyclical and pulsatile, and the periodicity is determined by the hypothalamus; for pulsatile, for example, after sleep, the secretion of growth hormone increases significantly during the slow-wave sleep period, especially in adolescents during the 10-20 minutes after slow-wave sleep, the secretion of growth hormone is the most vigorous, and the secretion is the most abundant and can reach a certain peak. In addition, exercise also affects growth hormone secretion. Generally, growth hormone secretion increases significantly after 10-20 minutes after exercise, and exercise intensity, exercise time, and exercise mode also have effects on growth hormone. In addition, food intake also has an effect on growth hormone secretion, for example, high sugar food can inhibit growth hormone secretion, while relatively low blood sugar can stimulate secretion, and high protein diet can inhibit secretion, while relatively lack of nutrition will stimulate secretion. Growth hormone is a hormone of the anterior pituitary gland that promotes growth and metabolism as well as stimulates hematopoiesis and immune regulation. The physiological effects of growth hormone are age dependent, for example, in young individuals, when it mainly promotes growth and regulates metabolism. If you want your growing child to reach the ideal height, you should pay attention to the physiological characteristics of growth hormone secretion.
