Sunbathing helps prevent colorectal cancer

At present, colorectal cancer has jumped to the second place in the cancer rankings. The incidence of colorectal cancer in my country is also increasing, which makes people panic and take various preventive measures to prevent it. Studies have shown that proper sun exposure can effectively prevent colorectal cancer.

Sunbathing can prevent colorectal cancer

A study in the United States reminds us that sunlight is closely related to the incidence of colorectal cancer. The southern United States has long sunshine hours and a low incidence of colorectal cancer. This shows that vitamin D has a certain positive effect on the prevention of colorectal cancer. White-collar workers who do not see sunlight all day in the office and go out by car must have limited vitamin D content in their bodies. Since there is a lack of vitamin D synthesized by sunlight, some people may wonder: Is it effective to take enough vitamin D from the diet? There is an opinion that vitamin D in the diet works in the body; but another opinion is that no matter how vitamin D is taken in the diet, it must be accompanied by vitamin D in the sun to play its due biochemical role. Many bedridden elderly people use oral vitamin D to prevent osteoporosis, but the effect is not ideal. Because research results show that vitamin D is not absorbed without the participation of ultraviolet rays and the stimulation of exercise.

White-collar workers should get more sun

This result is a wake-up call for white-collar workers who do not exercise often and often stay at home in office buildings. Many white-collar workers do not care about not defecating for one or two days, thinking it is no big deal. However, if the stool is stuck in the intestine for a long time, it will become increasingly dry and difficult, which will damage the intestinal wall over time, leading to toxin accumulation and cell degeneration. Therefore, white-collar workers should go out and get more sun after work, which can not only exercise the body, but also absorb ultraviolet rays, promote the absorption of vitamin D, and achieve the purpose of preventing rectal cancer.
