The seasons of the year have different effects on children’s growth and development. Spring is the fastest growing season for children’s height, while autumn and winter are dominated by weight gain, but the energy accumulation that works in winter is a strong guarantee for children’s height growth. Generally, in the middle of March, April and May, the value of height gain is equal to 2 – 2.5 times of the height growth in 3 months from September – November. And how to bring this 2 – 2.5 times growth, winter preparation is particularly important. Winter is not conducive to height gain because of low temperatures, less activity and less light, but winter can accelerate the maturation of bone age and weight gain at a significant rate if not properly maintained, which is extremely detrimental to height gain, and without a strong energy reserve, it is not possible to achieve a sudden increase in spring growth. So how should you reserve energy in winter to achieve long height, “should 4 good” advice, that is, sleep well, eat well, exercise well, good body. Muscle relaxation during sleep is good for joint and bone stretching, and also good for the secretion of growth hormone that can promote growth. Therefore, children should sleep more than 9 hours to accumulate internal power. Eat well, not eat well, but 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, etc., in addition to vegetables, fruits, etc. can be supplemented with a variety of vitamins, can not be picky and diet deviation, resulting in endocrine system disorders. The third is good exercise, 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. Appropriate exercise can make normal children’s growth hormone amount reach a peak value. In fact, for patients with short stature, winter is a good time for treatment, because this is the time when the body is most abundant in growth hormone accumulation. However, it is also important to prevent and control various chronic diseases, such as bronchial asthma, congenital heart disease and malnutrition, which can cause growth disorders.
