A person’s height is most influenced by parental genetic factors, but the development of good habits, can promote genetic potential to achieve maximum play, and even more than genetic height, which should try to do the following four points: 1, to ensure adequate and balanced supply of nutrients Adequate nutrition refers to the daily intake of sufficient calories and a variety of nutrients, including protein, fat, carbohydrates, dietary fiber, vitamins, organic salts and water. Vitamins, inorganic salts and water, etc. Protein is particularly important and should be mainly animal protein, such as pork, beef, fish, etc.; carbohydrates and fat are also essential nutrients for human growth and development, carbohydrates are mainly derived from rice and flour grains, so we should ensure the appropriate amount of meals every day; adequate intake of calcium and vitamin D is beneficial to the growth of human bones. In addition to ensuring the quantity of diet, we should also pay attention to the reasonable combination and diversification of diet, i.e., coarse and fine, meat and vegetables, not picky and not partial food. Do not eat too many snacks, thus affecting the intake of important nutrients. 2, adhere to physical exercise, pay attention to the combination of work and rest Some studies have confirmed that children who exercise are on average 2 to 3 cm taller than children who do not exercise. Exercise can stimulate growth hormone secretion, promote metabolism and enhance appetite. Children and adolescents often engage in sports, can promote the growth of bones, so that the bones become longer and thicker, and bone density increases. At the same time, regular exercise can improve muscle strength, speed and endurance. It can also consume excess fat and can effectively prevent obesity. Supervise the child 20 to 40 minutes of effective exercise time every day. The so-called effective exercise means that after exercise to make the child’s heart rate of 120 to 140 times / min, and appear sweating, fever, rosy face. 3, to ensure adequate sleep and a happy mood Promote the growth of the human body growth hormone in the night in a pulse-like secretion, one hour after bedtime secretion reached a peak, every 3 to 4 hours secretion, secretion is more than half of the total amount of the day, so to ensure adequate sleep is conducive to growth; at the same time sleep muscle relaxation, conducive to joint and bone stretching. The length of sleep varies from age to age and varies greatly from individual to individual. The required sleep time for one day and night is 16-20 hours for newborns, 12-14 hours for 1 to 3 years old, 11-12 hours for 4 to 6 years old, 10 hours on average for 7 to 10 years old, 9 hours for 10 to 14 years old, and about 7-8 hours for adults in general. And to ensure that the child carefree mood, the growth and development of children also has a great role in promoting. 4, prevention and control of disease Various acute and chronic diseases that cause physiological disorders can have a direct impact on the growth and development of children. Generally, the effect of acute diseases on growth is temporary, especially in the case of good nutritional status, can be quickly recovered. However, recurrent respiratory infections and diarrhea can significantly impede growth and development in children, so it is important to actively prevent and treat diarrhea and recurrent respiratory infections in infants. In addition, diseases such as chromosomal abnormalities, endocrine disorders, bone and cartilage development disorders, severe congenital heart disease, and chronic renal insufficiency can have a significant impact on growth and development and are medically known as pathological dwarfism. Some of them can be fully or partially recovered through early diagnosis and treatment, such as clinical treatment with growth hormone for children with growth hormone deficiency is very effective; thyroxine for children with thyroid hormone deficiency is also very effective, all of which can significantly improve height and promote growth. Therefore, if a child is short in stature, he or she should seek medical consultation in time to avoid delaying the best time for treatment.
