The seasons of the year have different effects on the growth and development of children, and right now it is winter. What exactly does winter do to a child’s growth and development? In general, it is important to build a good foundation in winter to achieve a faster growth rate. The natural growth of children is reduced in winter compared to other seasons due to external conditions such as low temperatures, less activity and less light. However, if not properly maintained in winter, it will accelerate the maturation of bone age and weight gain at a significant rate, which is extremely detrimental to height gain, and without a strong energy reserve, it will not be possible to achieve a sudden increase in spring growth. So how should you reserve energy in winter to grow taller? Parents may wish to follow the “four good” principle, that is, good sleep, good food, good exercise, good body. 1, sleep well: sleep muscle relaxation, conducive to joint and bone stretching, but also conducive to the secretion of growth hormone that can promote growth. So children should sleep for 9 hours to build up internal power. 2, eat well: not only eat well, but also eat a balanced diet, to ensure the daily intake of protein, fat, carbohydrates and a variety of trace elements such as iron, copper, iodine, chromium, calcium, zinc, in addition to vegetables, fruits, etc. can be supplemented with a variety of vitamins, can not be picky, partial food, resulting in endocrine system disorders. 3, exercise good: exercise is conducive to bone calcium and phosphorus metabolism, accelerating the deposition of minerals in the bone, so that the bone density increases and promote the secretion of growth hormone. Proper exercise can make the amount of normal child growth hormone reaches a peak value. 4. Good health: In fact, for children with short stature, winter is a good time for treatment, because this is the time when the body is most abundant in the accumulation of growth hormone. However, it is also necessary to prevent and control various chronic diseases, such as bronchial asthma, congenital heart disease and malnutrition, all of which can cause growth disorders.
