Height is the length of the longitudinal part of the human body, which originates from the longitudinal growth of the human body and is greatly influenced by genetic factors. The height development of girls is earlier than that of boys, growing rapidly at the age of 12- 13, and stopping at the age of 19-23, while the height development of boys is later, growing rapidly at the age of 15- 16 and stopping at the age of 20-25.
There are many factors that affect height, such as heredity, nutrition, exercise, environment, living habits, nationality, endocrine, sexual maturity (menarche age 18 ratio1height 5 cm), distant marriage, medical progress and so on.
Matters needing attention in expanding data to ensure normal growth and height of children;
1, supplemented by protein. Protein is the foundation of life, and the proliferation of bone cells and the development of muscles and organs are inseparable from protein. The faster the human body grows, the more it needs to supplement protein. Fish, shrimp, lean meat, eggs, peanuts and bean products are rich in high-quality protein, so we should pay more attention to supplement them.
2. Supply vitamins and cellulose. Vitamins are vital elements, among which vitamins A, B and C are the most important and necessary for human growth and development. Animals' livers, kidneys and eggs, especially vegetables, contain many vitamins, cellulose and minerals, so we should eat more fresh vegetables.
3. increase minerals. The height of human body depends on the growth and development of bones, among which the growth of long bones of lower limbs is most closely related to height. In other words, only the growth of epiphyseal chondrocytes in long bones can make the human body grow taller. Calcium and phosphorus are the main components of bones, so their absorption can be guaranteed, thus ensuring the healthy growth of bones.
4. Ensure adequate sleep. Sleep is also a "nutrient" that makes the human body grow taller. As the saying goes: people grow up in sleep. Because sleep can not only eliminate fatigue, but also after the human body falls asleep, the secretion of growth hormone is stronger and lasts longer than usual, which is conducive to growth and height. Therefore, develop regular living habits and ensure adequate sleep.
5. Take part in physical exercise. Regular physical exercise suitable for growing tall and strengthening the brain can promote blood circulation, ensure adequate nutrition of skeletal muscle and brain cells, promote bone thickening and bone density thickening, and strengthen the ability to resist compression and bending. Exercise can promote the secretion of growth hormone and make bones, muscles and brains develop better.
