The research of modern medical science has proved that there are the following factors affecting height.
1. Genetic factors
According to statistics, 79% and 92% of the height of men and women belong to genetic factors respectively. Foreign scholars have listed two formulas for the relationship between children and parents: son's height = (father's height + mother's height) × 1.08 ÷ 2, daughter's height = (father's height) × 0.923 + female height) ÷ 2.
2. Category of race
There is a dwarf tribe in the Talon region of Myanmar, which is less than 1.1 meters tall; The "Yucca" in the Columbia forest in South America are all under 1 meter. Europeans and Americans are generally taller than Asians.
3. Hormone secretion
Height depends on the secretion of human growth hormone. The growth hormone secreted by pituitary gland in patients with dwarfism is obviously insufficient; The height of women with gonadal hypoplasia is less than 1.4 meters.
4. Physical exercise
Sports activities help to speed up blood circulation and promote bone growth. According to statistics, teenagers of the same age and sex who often exercise are 4 ~ 10cm higher than those who don't exercise.
5. Trace elements
The study found that if the body is short of calcium, the bone will stop growing and get osteomalacia; Zinc deficient children not only lose appetite, but also have lower height and weight than children of the same age.
6. Sexual maturity
Generally speaking, those with late sexual maturity have a high body; Those with earlier sexual maturity are shorter.
7. Sunlight
Proper sunlight will increase the synthesis of vitamins in the body, which is very important for the gastrointestinal tract to absorb calcium and phosphorus and ensure the normal growth of bones.
Among the above seven factors affecting height, genetic factors and ethnic factors are relatively stable, while factors such as physical exercise and sunlight exposure can be controlled through efforts. Therefore, if you want to grow taller, it is a good way to actively participate in physical exercise.
