Height depends on genetic factors and early nutrient absorption. The height of human beings mainly depends on the length of long bones. When people are born, the epiphyses at both ends of long bones are mostly cartilage. With the increase of age, the ossification center of epiphysis appears, and it increases year by year, and bone tissue replaces cartilage tissue. But there is still a section of cartilage between the spine and epiphysis, called epiphyseal plate cartilage. This section of chondrocytes continues to divide and reproduce vertically in adolescence, growing new cartilage, and the part near the spine continues to bone, and the long bones grow out bit by bit, and people gradually grow taller. Until 18 ~ 20 years old, the epiphysis closed and the growth basically stopped. But there is still hope to increase before the age of 20.

Increase exercise

As long as a person is human, his back is more or less abnormally bent, and even his sleeping posture will directly affect the increase of his height. If this (abnormal bending) is corrected, all joints will become longer, thus increasing your height. You should not underestimate the time from bending to straightening of joints. There are so many joints in the human body that every little makes a mickle, of course, it is considerable. Regular physical exercise suitable for growing tall and strengthening the brain can promote blood circulation of the whole body, ensure adequate nutrition of skeletal muscles and brain cells, promote bone thickening and bone density thickening, and strengthen the ability of compression and bending. By jumping: running, skipping, aerobics, all kinds of ball games; Stretching: yoga, gymnastics, etc. Promote cell division and proliferation of epiphyseal cartilage.

Stretching action:

(1) Stand with your feet together and bend your upper body forward so that your fingers touch the ground. Do not bend your knees, and do 15~20 times continuously.

(2) Stand with your feet shoulder width apart and twist your upper body so that your fingertips touch your toes on the other side. Continue to do 10~ 15 times in all directions.

(3) Stand with your feet shoulder width apart, raise your arms to shoulder height, and then twist your waist to swing your arms back horizontally. Continue to do 10~ 15 times in all directions.

(4) Stand facing the wall, with the distance of 30 cm, toes inward, hands holding the wall and chest out, legs bent together, and hips protruding backwards. Do it 20 to 50 times in a row.

(5) Sit on the calf, open your shoulders backwards, and straighten your arms upwards. In this posture, your upper body leans forward as close as possible to the floor. Do it 20~40 times in a row.

(6) Sit down, straighten your legs, bend your body, and wrap your hands around your calves so that your chin touches your knees for 20 to 30 times in a row.

Jumping rope action:

The speed of skipping rope is self-regulated. Too fast or too slow is not appropriate. It should be adjusted according to the target rate of aerobic exercise, (220- age) ×60%~80%. After adaptation, you can gradually add a lot of intensity, and stick to it for a long time, which can enhance heart and lung function, exercise endurance and keep a good figure.

Jump method:

1. When feet jump together, there is a rebound action: every time you jump over the rope, your feet will be on the ground together;

2. Jump with your feet together without bouncing: that is, jump over the rope continuously;

3. One-legged jump: that is, two feet jump in turn, much like running;

4. Leg lifting and jumping: Lifting and jumping with both feet in turn can significantly improve thigh muscles.

Nutrition increase

First of all, add 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 and bean products are rich in high-quality protein, so we should pay more attention to supplement them.

Second, supplement 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.

Third, 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 epiphyseal chondrocytes in long bones keep growing can the human body grow taller. Calcium and phosphorus are the main components of bones. Therefore, milk, shrimp skin, bean products, ribs, bone soup, kelp, seaweed and other foods rich in calcium and phosphorus should be supplemented in May and June. In addition, we should go outdoors to bask in the sun and increase the chances of ultraviolet radiation, so as to facilitate the synthesis of vitamin D in the body and promote the absorption of calcium and phosphorus in the gastrointestinal tract, thus ensuring the healthy growth of bones.

Fourth, to 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.
