How do junior high school students grow taller and shorter quickly, and how to counterattack?
After junior high school students enter adolescence, the average height of boys increases by 7- 10 cm every year, and the average height of girls increases by 6-8 cm every year. So how can we grow taller scientifically?

The method of junior high school students' rapid growth is indispensable for bone growth.

Teenagers can't grow up without proper exercise. Exercise itself can promote the secretion of puberty growth hormone.

If you are a 3- 1 1 year-old child, at this stage, bone growth is in a rapid growth period, and it is necessary to supplement trace elements such as calcium, iron and zinc. protein is also indispensable. You must eat milk and eggs in the morning.

get enough sleep

Growth hormone will peak after sleep. If the sleep time is insufficient or the sleep quality is not good, it will lead to the decrease of growth hormone secretion, which will lead to short stature.
