With the improvement of people’s living standard, parents are more and more concerned about their children’s height. Every teenager is also very concerned about their own height, hope to grow in some, scientific research has found that a reasonable lifestyle is beneficial to children and teenagers to grow taller. First, a reasonable dietary structure on the height of a very important role in promoting 1, the diet should be balanced food quantity to be sufficient, cereals, meat, fruit, vegetables should be eaten, food diversification, coarse and fine, meat and vegetables, each other complement each other’s strengths. 2, protein should be enough adolescent development, the demand for protein is much higher than adults, such as the supply will affect the growth of height. Food to animal lean meat, fish and shrimp meat, poultry and eggs, dairy, beans and their products rich in protein. In addition, collagen and mucin is an organic component of the composition of the bone, adolescents should be supplemented in a timely manner, the food in the skin, pig’s trotters, chicken, fish, turtle, etc. are rich in collagen and mucin. 3, calcium should be appropriate, according to the survey, calcium-deficient children calcium supplements than those who do not supplement calcium much higher. 4, iron, zinc can not be less if the food supply of iron is insufficient, will inevitably make the hemoglobin synthesis is blocked, and cause a lot of organs and tissues of the physiological function of the abnormalities of growth, intellectual development, immune function, cell metabolism, etc. will be affected. In daily recipes, animal liver and other internal organs, red meat (refers to beef, lamb, etc.), egg yolk, fish and beans are very high in iron content, and the bioavailability is also high. In addition, zinc is associated with the gonads and the secretion of gonadotropins, which have a great impact on the growth, development and intelligence of adolescents. Therefore, zinc-rich foods such as oysters and animal liver should be supplied regularly. Appropriate aerobic exercise is conducive to growing taller Since exercise is also a way to promote the secretion of growth hormone, appropriate exercise is conducive to growing taller. Aerobic exercise is good for height growth. Aerobic exercise is defined as: ① medium intensity (exercise intensity is too big, too small are not good, just stop when the heartbeat at 120 ~ 150 times / min more appropriate), ② regular, continuous exercise, ③ each time not less than 20 minutes (for those who need to reduce weight, it is best to reach half an hour each time), ④ as much as possible in the outdoors: everything grows by the sun, the growth of human beings is also the same. The reason why the height of people in the northern region is higher than that in the south is due to climatic factors as well as the factor of sunshine time. Exercise in the form of jogging, slow jumping rope, etc. is good. Ball games, swimming, etc. can also be, but need to pay attention to maintain the continuity of exercise . It should be noted that too strenuous exercise is anaerobic exercise, will cause oxygen deficiency, but not conducive to growth. Continuous time too long exercise also exists on the negative side. Third, ensure sufficient sleep is beneficial to growth Growth hormone is the most important hormone of human growth, growth hormone secretion is mainly secreted in deep sleep. Therefore, it is important to ensure adequate sleep. School-age children generally need 8 to 9 hours of sleep a day. It is certainly better to go to bed earlier, not just at what time the growth hormone is secreted as some people understand it, but only in relation to the depth and total duration of sleep. Modern people’s sleep time is later than in the past, but not shorter, but due to improved nutrition, timely and effective control of diseases and so on. Fourth, eliminate the negative factors affecting growth Although appropriate diet, sleep, exercise is conducive to growth, but do not be too superstitious about these aspects and do not go to the treatment of related diseases. If you find that there is obvious shortness, precocious puberty or developmental abnormalities, you need to consult a doctor in a timely manner to find the cause of the disease, and if necessary, treatment is necessary. And note that some drugs such as adrenocorticotropic hormone, quinolone antibacterial drugs, etc. have inhibited height growth, need to avoid the application, and maintain a good psychological state. In conclusion, growth is a complex biological phenomenon, its basic process is regulated by genetic factors, and gene expression is influenced by the internal and external environment. Scientific treatment of children’s growth, pay attention to adjusting children’s eating habits, reduce snacks, increase outdoor activities, especially jumping, stretching class, ensure sleep time, improve sleep quality, will make children grow faster and better.
