Seasons do have a strong relationship with growth and development, both in terms of height or weight to varying degrees. Height growth is generally fastest in the spring, while weight gain is fastest in the fall. Height gains are rapid during the 3 months from March to May. Seize the growth season – feed your kids well In addition to protein, fat and carbohydrates, pay attention to micronutrients and vitamin supplements. Zinc is involved in the synthesis of many enzymes and plays an important role in nucleic acid metabolism and protein synthesis. Zinc deficiency can cause growth retardation and anorexia. Calcium, phosphorus and trace amounts of magnesium and manganese are especially needed for bone growth. Iodine is necessary for the synthesis of thyroxine. And thyroxine is essential for height and development. Vitamin A Deficiency of vitamin A can cause short and thick bones. Vitamin C Deficiency of vitamin C can lead to insufficient intercellular matrix and increased fragility of bone. Vitamin D Vitamin D regulates the metabolism of calcium and phosphorus, and its deficiency can cause the bones to soften and bend, resulting in short stature. Seize the growth season – let your child sleep well Hormones that promote human growth: the amount of growth hormone secreted during sleep is about three times that secreted during wakefulness, so getting enough sleep is good for growth. During sleep, muscles are relaxed, which is conducive to joint and bone stretching. “Spring sleep is the best time for us to sleep, so try to let children sleep early, sufficiently and well to ensure the secretion of growth hormone. Seize the season of growth – let children fully exercise Exercise can stimulate the secretion of growth hormone, and about 20 minutes of effective exercise can make the secretion of growth hormone in normal children reach a peak value. Children often exercise to promote long bone growth. In spring, when the climate is suitable for exercise, parents should let their children fully exercise in nature, enjoy the fresh air and sunshine, and promote their physical and mental development.
