First, strictly speaking, fitness can not stimulate the increase of androgen, but should be called maintaining androgen level, or let androgen level slowly decline. For example, when people are in the best physical condition in their twenties, the androgen is the highest, such as 800ng/DL. By the age of 30, due to the pressure of work and family, improper entertainment and diet, the androgen has dropped to 500ng/DL. If proper exercise is carried out, the androgen may recover to above 600, 700, or even close to 800ng/DL.
Fitness is impossible to make your androgen level exceed the original maximum androgen level! For example, your maximum androgen is 800ng/DL, and your fitness can't exceed 800ng/DL.
Being depressed will reduce your androgen by 30%, and being happy will restore your androgen by 30% in a few days, because the secretion of androgen is instructed by the brain.
The regulating effect of fitness on androgen may be mainly to regulate mood. Relaxation, good circulation and good sleep are the keys to maintaining androgen. Stress, poor sleep, improper diet, smoking and drinking are the main reasons for the decline of androgen in many people.
If you exercise too much, it will be counterproductive. Studies have shown that long-term long-distance running or long-term heavy fitness will reduce androgen in the body. People with big muscles may not have much androgen in their bodies. A person who runs occasionally, has a scientific diet, gets enough sleep, and feels faster, the androgen may be 750ng/DL, while a person who is physically fit for a long time may only be more than 500 ng/DL.
Second, hair loss is caused by androgen. This outdated statement has long been a popular science and is very wrong. Clinical trials show that the proportion of male alopecia in human body is not high, and some people are still in a state of low or high estrogen. Hair loss is mainly genetic. People with genetic predisposition, once the body appears sub-health and the hormones in the body are out of balance (high estrogen), may lead to hair loss.
Therefore, fitness will not only aggravate hair loss, but also improve your sub-health and balance your hormones, thus delaying the occurrence of hair loss.
