First, don't miss the period of rapid growth. When does the height of children grow fastest during puberty? Studies have confirmed that the height of most Han children in China is about 12 years for girls and 14 years for boys. More than 90% of the girls are between 1 1- 13 years old and the boys are between 13- 15 years old. In order to make children grow taller, parents should pay special attention to their nutrition and exercise during the rapid growth period. Second, we should pay attention to nutrition, which is the key to children's physical growth. The energy, protein and amino acids needed for normal growth of the body must be provided by food, mainly meat, eggs, beans and beans. Bone formation also requires sufficient calcium, phosphorus and trace amounts of manganese and iron. Insufficient calcium intake and vitamin D deficiency will lead to insufficient bone mineralization, vitamin A deficiency will make bones shorter and thicker, and vitamin C deficiency will make bone cells brittle and affect bone growth. At present, the average family should have a comprehensive and adequate nutrition and a balanced diet. Parents should be careful not to let their children develop the habit of partial eclipse, let alone let their children eat too many snacks, which will affect the intake of important nutrients. Third, don't ignore that physical exercise can strengthen the metabolic process of human body, accelerate blood circulation, promote the secretion of growth hormone and accelerate the growth of bone tissue, which is beneficial to human body length. The following kinds of exercises have a certain effect on height growth, so try them. 1. The hanging swing adopts a horizontal bar or a door frame, and the height should be such that the body is hung on the bar and the toes can just leave the ground. Hold the lever with both hands, the distance is slightly larger than the shoulder width, the feet are close together, and then the body swings back and forth, not too much, not too long. It is best to arrange exercise every morning and try to relax and droop for 20 seconds. Young men should do 10 ~ 15 times, and young women should do it 2 ~ 6 times. 2. When jumping up and down, touch the preset object with both hands, which can be branches on the roadside, basketball baskets or ceilings. Jump with your feet and do it 30 times. Take a rest and jump with your left foot and right foot, as above. 3. When playing basketball in ball games, actively strive for rebounds and jump shots to break the ball; Try to jump up when playing volleyball, and do more smash and block; Practice jumping up and hitting the ball on the forehead in football. 4. Jumping exercises can be one-legged jump, frog jump, triple jump, multi-stage jump and vertical jump in situ. Fourth, don't forget to create a good living environment for children. Abnormal mental nervous system will also affect children's physical development. If parents divorce, the relationship between children and guardians is abnormal, children are often abused, or children are seriously stimulated, their growth rate will gradually slow down, making their height lower than the lower limit of normal children of the same age and gender. Being short will aggravate a child's sense of inferiority, which is due to the psychological and social stimulation to the child, which affects the transmission of nerve impulses from the cerebral cortex to the hypothalamus, thus inhibiting the secretion of growth hormone by the pituitary gland. When the child's environment is handled, the growth rate can return to normal. Five, do not forget to actively prevent and treat children and adolescents with chronic diseases should be actively treated. Chronic infection, chronic hepatitis, chronic nephritis, asthma, heart disease, anemia and other long-term diseases will affect growth and development. Genetic diseases of bones, such as osteochondral dysplasia, can also limit the growth of bones. "mom! Because of you, I was born so short. " Jia Xiang, a junior high school student, has been sitting in the front row since elementary school. Seeing that her height was getting worse than that of other students, she complained angrily to her mother. "Who told you not to drink more milk? You don't exercise at ordinary times!" Mother answered him grumpily. When children grow up, parents care not only about their health, but also about whether their children will grow tall and strong in the future. Pediatric clinics and online health consultation websites often see parents anxiously asking, "Doctor, why is my child not tall?" "Drink more milk to help? Some impatient parents even inquire about the prescription of "increasing height" everywhere, hoping that their children will grow a few centimeters taller. However, some people think that people's height is determined by genes, and nutrition and exercise have little effect. How tall a person can grow is born, or do you have to work hard the day after tomorrow What can a developing child do to have a chance to get ahead? Judging from the growth rate of bone age, people gradually grow taller in the process of growth, which is the result of bone growth and development, mainly in the growth of lower limb bones and vertebrae. The growth of lower limb bone is formed by the growth plates of femur and tibia. Growth plates are located at both ends of the bone. Stimulated by the growth hormone secreted by pituitary gland, they will constantly proliferate cartilage, and the new cartilage will become hard bone after calcification, so the bone will become longer and wider. From birth to 1 year-old, the child grows fastest in his life, and then the speed gradually slows down. Until adolescence, sex hormones begin to interact with growth hormone, and the child's height and weight begin to increase sharply. Wang Zhihong, an attending physician in orthopedics at National Taiwan University Hospital, pointed out that the progress of a person's height should be evaluated together with the "bone age" (the age of bone growth and development), not just by the average age. Some precocious children, the progress of bone age is faster than the actual age, and their height is more prominent than that of their peers at the beginning, but it is not necessarily that adults will grow taller later. How long our height can grow depends on the closure of the whole body growth plate. If the growth plate is closed, it means that the bone has matured, the bone no longer grows, and the height will not increase. What factors will affect a person's height? Heredity determines your height. The most important determinant of a child's height is heredity.
