Mental factors
If a person is depressed for a long time, in a bad mood or highly nervous and overworked, his hair can turn from black to white. For example, during the Spring and Autumn Period and the Warring States Period in China, Wu Zixu, a doctor of the State of Wu, suddenly became white-haired overnight in order to muddle through Zhaoguan. Hugo, a French writer, described in his Les Miserables that when the mayor of Hou Delin decided to admit that he was a prisoner in court after a fierce and painful ideological struggle, "his gray hair turned white after only one hour". Both historical legends and literary descriptions are exaggerated, but after all, it shows that people have long believed that the change of hair from black to white is related to mental factors.
Poor nutritional status
Hair is an appendage of the skin, and it needs adequate nutrition just like other organs and tissues in the body. Different races have different hair colors. White people have blond hair, and brown people have red and black hair. We yellow people are brown and black because the pigment particles in our hair contain copper, cobalt and iron. If you lack inorganic salts such as copper, cobalt and iron in your diet for a long time, it will naturally affect the synthesis of melanin and make your hair turn from black to white. In addition, according to medical clinical observation, if the body lacks protein, vegetable oil, vitamin B 1, vitamin B2 and vitamin B6 for a long time, it will also lead to the hair turning from black to white.
Drug inheritance of diseases
Diseases, drugs and heredity are also factors that cause hair to turn from black to white. Endocrine disorders such as pituitary dysfunction and hyperthyroidism, consumptive diseases such as tuberculosis, typhoid fever and pernicious anemia, and autonomic nervous dysfunction are all diseases that have been found to be related to hair turning from black to white.
Hyperfunction of brain
It is found that mental workers are in a state of high pressure for a long time, with high mental tension and no time to take care of physical exercise. Coupled with unbalanced diet and bad living habits, they are prone to premature gray hair. So how to prevent white hair?
When people reach a certain age, their hair will gradually turn white because their metabolism becomes lower and their functions weaken, which is a normal physiological phenomenon of the elderly. And some people turn white at a young age, which is not consistent with their age. According to experts, stress is an important factor leading to gray hair. Therefore, young patients need to adjust their mental state properly, relax more after work and strengthen physical exercise, which can prevent white hair.
In addition, reasonable and healthy eating habits can also prevent white hair. Usually you need to pay attention to the quality of your diet and eat more substances, vitamins and trace elements rich in protein. In addition, we should try to avoid spicy and irritating foods, and put an end to some foods rich in refined sugar and flour, which is not conducive to hair growth.
Perhaps most young people like to drink soft drinks, alcoholic drinks, cakes and the like. According to experts, such a diet will greatly weaken the strength of the human body, leading to hair loss, wrinkles, skin irritation and premature aging. In view of this, young people should appropriately supplement foods rich in vitamin B, including eggs, fish, beans and dairy products, so as to promote human metabolism and help prevent white hair.
In short, white hair caused by stress is not enough to cause permanent white hair. Only when patients need to supplement quantitative nutrition and adjust their psychological state can they get twice the result with half the effort in prevention and treatment.
