Height generally depends on genetic factors, but why are most children taller than their parents now?

Now that the conditions are good, children have good nutrition and a lot of exercise since childhood. The height will naturally go up. Now research shows that 70% of children's height is influenced by genetic factors and 30% by acquired factors. So does this mean that if the child's parents are low in height, the basic child's height will not be much higher? Of course not. Although genetic factors have a great influence on children's height, acquired factors are also very important, and children now eat better than before, unlike their parents when they were young, so parents' height is not a hard standard to measure children's height.

Comprehensive nutrition, children's physical development and comprehensive nutrition absorption are inseparable, nutrition can not keep up with the needs of bone growth, of course, will slow down the height development. Therefore, it is closely related to height from breastfeeding after birth, to adding complementary food to a 6-month-old baby, and then to developing regular eating habits, diet matching and nutritional balance after the baby grows up.

Reasonable exercise, to ensure adequate nutrition, but also with reasonable exercise, can make the body better absorb nutrition. Moreover, scientific and reasonable exercise can also promote the secretion of growth hormone and squeeze the maximum potential of genetic factors. Adequate sleep produces less growth hormone during the day, while night is the main time for growth hormone secretion. It takes about 2 hours to get a high score, so a high-quality sleep and good sleep habits are very helpful for height growth.

Scientific research has found that genetic factors are the main factors that determine the height of children. If both parents are relatively low in height, there is a high probability that the child's height will not be very high, and this factor is uncontrollable. But genetic factors are also very accidental, because there are dominant genes and recessive genes, depending on whether recessive genes or dominant genes control height traits, and also combined with acquired nutrition and development, so the height inheritance of children does not depend entirely on the height that parents can see.
