What are the benefits of sunbathing?

　　It is now known that maintaining high levels of vitamin D in the body reduces the risk of aggressive tumor formation. It has also been found in other epidemiological surveys that elderly people living in high northern latitudes male , many die from prostate cancer. This situation is also related to the relatively low content of vitamin D in their bodies.

　　UV rays help prevent prostate cancer

　　The incidence of prostate cancer is much higher among black men in the United States than among men of other ethnic groups. One of the main reasons is that they skin It contains a lot of melanin. This pigment effectively blocks ultraviolet rays in the sun from being absorbed by the body. The production of vitamin D in the body requires the induction of ultraviolet rays.

　　On the other hand, vitamin D also inhibits cell growth. The formation of many tumors is due to the excessive growth of epithelial cells or endothelial cells in the body and becomes "crazy growth".

　　How to supplement vitamin D

　　In the past, many people advocated drinking more milk in order to obtain more vitamin D, because milk usually contains vitamin D additives. But this method is not enough. The reason is that the calcium content in milk is also very high. Excessive accumulation of calcium in the body will also increase the possibility of prostate cancer.

　　Experts believe that the normal level of vitamin D in the body should be maintained at around 400 international units per day. But if we only rely on food intake, most people may not be able to meet this standard. Therefore, it is best to have 15 minutes every day to allow the body to receive sunlight to help the body naturally produce enough vitamin D, so that prostate cancer is less likely to occur. Of course, too high levels of vitamin D in the body can be harmful, just as excessive sun exposure can induce skin cancer.
