Touching your head won't make you grow taller. This is just the statement of the older generation, and there is no scientific basis. Main factors affecting height:

(1) Genetic factors from parents have great influence on growth and development, but they are not static.

(2) The effects of diseases, such as liver and renal insufficiency, will affect the transformation of growth hormone into growth hormone medium and the regrowth of height.

(3) Children's own physical condition leads to malnutrition and affects their development. The function of endocrine glands is particularly important, such as growth hormone and thyroxine.

(4) Psychological factors, such as some kind of fright, excessive psychological pressure and anxiety, will affect the function of the anterior pituitary gland and reduce the secretion of growth hormone.

In order to promote physical growth, we need to pay attention to the following aspects:

(1) Adequate and balanced nutrition, especially appropriate supplementation of animal protein, can promote the absorption of trace elements such as zinc, iron and B vitamins, and it is very beneficial to give children a glass of milk before going to bed every night.

(2) Insisting on physical exercise, paying attention to the combination of work and rest, and being happy are the catalysts for height growth. Specific physical exercises, such as pull-ups, playing basketball, volleyball, skipping rope, etc.

(3) ensure adequate sleep and should not cause excessive fatigue of the body.
