Children’s scientific height increase includes the following aspects: (1) reasonable nutrition Ensure and urge children to have a balanced daily nutritional intake, such as protein, zinc, iron and B vitamins that affect height, especially to properly supplement animal protein, because protein deficiency will directly affect height growth; therefore, ensure to drink 250-500 ml of milk, eat 1-2 eggs and an appropriate amount of various meats, cereals and fruits and vegetables. It is better to have a balanced diet, i.e. a reasonable mix of meat and vegetarian dishes, and a balanced intake of coarse and fine grains. (2) Adequate sleep Since growth hormone is the most important hormone for human growth, and the secretion of growth hormone is mainly secreted during deep sleep, it is important to ensure sufficient sleep. Developing children should go to bed early, get up early and have sufficient 8-10 hours of sleep so that growth hormone and other hormones related to growth and development in the body are in the best state of secretion and function. (3) Sunny air and outdoor activities: Since exercise is also a way to promote the secretion of growth hormone, exercise can promote the development and sound function of children’s bones, muscles, joints and ligaments. Supervise your child to have at least 20-40 minutes of effective exercise every day, with your child sweating, warming up and looking rosy. Exercises that can promote height growth include: pull-ups, basketball, volleyball, jumping, rope skipping, shuttlecock and fast running. (4) Reduce mental and psychological stress and keep a happy mood Depression can inhibit growth hormone secretion. (5) No disease Keep healthy, various diseases, especially chronic systemic diseases can cause short stature. (6) Pay attention to your child’s height and measure it regularly to determine whether the development of height and bone age and sexual development are normal. If your child’s growth deviates from normal, you should look for the cause and deal with it in time, so as not to miss the time of treatment.
