How much is a child's height genetic?

In addition to facial features, height also occupies a very important part of human appearance. People who are too short often have inferiority complex, which affects their children's interpersonal communication. Therefore, most parents hope that their children can grow tall and strong. In fact, human height is not only related to acquired growth factors, but also innate genetics will affect the child's height. So for a child's height, how much does genetics account for?

How much is a child's height genetic?

Many people believe that if parents are tall, their children will definitely be tall. In fact, genetic factors account for 70% of height, and it is very common for children's height to "betray" their parents.

The genetic height of the child is calculated by the following medical formula:

Son's adult height (cm) = (father's height + mother's height) ÷ 2 + 6.5

Daughter's adult height (cm) = (father's height + mother's height) ÷ 2-6.5

How do children grow taller?

1. Eat: One cup of dairy products per day

First of all, we should pay attention to nutrition in our daily life. Protein is very important in the growth and development of children. Fish, shrimp, lean meat, eggs, peanuts, soy products, etc. are rich in high-quality protein. Drinking a cup of dairy products a day is the secret to growing taller. Zinc is a key factor in height growth. Eating more related foods can prevent short stature caused by zinc deficiency. Easily absorbed zinc-containing foods are animal foods, such as pork, beef, lamb, animal liver, etc.

2. Movement: Stretching exercises help to grow taller

Secondly, exercise is an effective way to stimulate height growth. Teenagers should participate in more light and stretching exercises, such as skipping rope, hanging on the horizontal bar, swimming and various ball games. Each exercise should be no less than 30 minutes and should not be less than 3 times a week, but "weight-bearing" exercises such as weightlifting are not suitable.

3. Get enough quality sleep

In addition, there has been a saying since ancient times that "babies who can sleep well grow taller." This rule summarized by the public does have a scientific basis, because the peak secretion of growth hormone is during deep sleep, and the secretion of growth hormone at night is three times that of the day. After the child falls asleep, the secretion of growth hormone gradually increases from 9 pm, reaches a peak at around 12 midnight, and gradually decreases after 5 am. Children nowadays have many entertainment activities. If they often go to bed late due to reasons such as surfing the Internet, the secretion of growth hormone will be affected. After one or two years, their height will be significantly lower than that of children who go to bed early. Liang Liyang suggested that children should avoid light stimulation before going to bed. For example, watching TV or using computer for more than 2 hours will make the brain very excited and inhibit the secretion of growth hormone.

How much of a child's height is due to genetics? A large part of a child's height is inherited from his parents. Generally, if the parents are tall, the child born will not be short. Parents who have short children don’t have to worry, as they can make their children taller through acquired supplements. However, you cannot supplement blindly. You must supplement nutrition reasonably and scientifically to avoid overnutrition.
