People with long white hair are not prone to cancer, is there any scientific basis? What is the effect of gray hair?

White hair gives people the feeling of aging. When people reach middle age, they will start to grow gray hair slowly, this is because the various functions of the human body are constantly beginning to decline. However, there is now such a saying on the Internet: "People with long white hair are less likely to get cancer."

Is this true? Is there any scientific basis?

The reason why people say this online is that human hair is part of the human body. White hair grows on the head to protect the body from damage to the cells in the body, so that it can achieve the effect of preventing cancer. However, human gray hair has nothing to do with cancer, and there is no scientific basis for it. For example, when we are in the hospital, we will see some cancer patients, because of the disease and chemotherapy, the head flower will dry up and fall off. This is because the human body is affected by the disease, and the body does not have enough nutrients to nourish the hair. Coupled with chemotherapy, the immune system in the body is destroyed, and the endocrine in the body is disturbed, which can also lead to the appearance of white hair. If the hair can cause some cancer, then shave the hair, will the cancer be cured? Therefore, only when the body is healthy can excess nutrients be supplied to the hair, and the hair quality will be good at this time. Therefore, there is no relationship between gray hair and cancer.

Why do you grow white hair?

First of all, we have to figure out why people grow white hair? Hair is a kind of human hair, and most of the people in our country have black hair. Of course, some people are born with gray hair, which is mainly caused by congenital family history. More people belong to acquired gray hair.

age

As we age, our body's metabolism actually slows down. The hair of normal young people is constantly undergoing metabolism, and the old hair will fall off automatically when its lifespan is up, resulting in hair loss. At the same time, new hair is constantly growing, so when you are young, many of your hair looks dark and thick. However, in middle age, various functions of the body continue to decline, new hair growth slows down, and old hair slowly turns white.

undernutrition

Because hair is a part of the body, its growth also requires the human body to provide him with nutrients. In addition to the fact that people in our country have black hair due to genetic reasons, there is also a point that the pigments in the hair contain copper, iron and other substances. If these elements are lacking in the body, it will naturally affect the color of the hair. Just like when some people are young, because of malnutrition, their hair will appear more dry and yellow, instead of normal black. In addition, if the body lacks nutrients such as protein and vitamins, it will also cause the hair to turn gray.

overuse

In some third-year high school parties, there will be a situation of "juvenile whiteheads". But not because of family inheritance, but because of overuse of the brain. They often need to use their brains for academic reasons. This long-term use of the brain, coupled with nutritional deficiencies and other reasons, will lead to white hair.

mental condition

Another reason for the third party's whiteheads is because of too much pressure. In order to achieve a satisfactory result in the college entrance examination, these students study hard every day and fight at night. Long-term mugwort leaves and mental stress can also cause hair to turn from black to white.

There are also people whose hair turns white because their emotions are too extreme. Just like Wu Zixu, a famous official in the Spring and Autumn Period and the Warring States Period, in order to escape, his hair turned white overnight in a hurry.

Therefore, long white hair has nothing to do with cancer, it is mainly caused by its own reasons.
