Which part of the human body ages first?

I believe that when talking about aging, everyone is familiar with it. Everyone has elderly people in their family. People will always age, so there is a way to avoid aging. You just need to take care of the parts that age first. Well, some people will ask, what is the first part of the human body to age so we can be on guard. Let me reveal the answer to you below, please watch.

Facial skin: Women begin to develop their first wrinkles at the age of 19 and a half; men's facial skin begins to become dry, rough, and loose at the age of 35, and the facial contours become less clear.

Lungs: Start to age at age 20. Lung capacity begins to decline slowly at age 20, and by age 40, some people begin to experience breathlessness. At age 30, men inhale 946 ml of air with each breath, but by age 70, this number drops to 473 ml.

Brain and nervous system: Start to age at age 22. The number of nerve cells in the brain will gradually decrease. After the age of 40, the number of nerve cells will decrease at a rate of 10,000 per day, which will affect memory and brain function.

Hair: Men's hair starts to turn gray after age 30, while women's hair starts to turn gray around age 35. After 60, the number of hair follicles decreases and the hair becomes thinner. Hair is black because it contains a pigment called melanin. The human body does not have a unified gland that secretes melanin. Melanin is produced separately in each hair, so hair always turns white one by one.

Breasts: Start to age at age 35. As the levels of estrogen and progesterone in women's bodies decrease, their breasts gradually age and sag. After the age of 40, the areola will shrink dramatically.

Muscles: Start to age at age 30. Muscles are constantly growing and depleting; growing again and depleting again. After the age of 30, muscle loss outpaces growth. After the age of 40, people's muscle mass begins to decrease at a rate of 0.5% to 2% per year.

The word aging, when heard, makes people feel very scared. Although aging cannot be stopped by humans, it can certainly be slowed down. In our daily life, we should pay attention to ensuring that our mood is happy and we can do some appropriate recreational activities. Dancing is a good choice, and square dancing is very popular nowadays. You should also pay attention to a reasonable diet.
