Staying up late to work overtime may also "simmer" out of cancer! According to reports, the World Health Organization has recently included overnight work in the "possible carcinogenic factors". With ultraviolet rays, car exhaust, smoking, etc., overnight work has become one of the risks of cancer, which also means that cancer has become an occupational disease.

　　"Overnight work may indeed be one of the causes of cancer." Zuo Wenshu, executive member of the China Anti-Cancer Association and chief physician of Shandong Cancer Prevention and Control Institute, told Life Times that "working at sunrise and resting at sunset" is a law formed by the human body to adapt to the natural environment, and staying up late for a long time will affect the higher nerve center, disrupt the endocrine system, and affect the immune mechanism, which will make it easier for people to suffer from cancer. Researchers also believe that the night light impedes the generation of melatonin, which can inhibit the growth of a variety of cancer cells.

　　"For people in certain occupations, the risk of cancer is higher than for the general population." Zuo Wenshu said that this is mainly closely related to the bad environment they are exposed to at work. A report released by the World Health Organization shows that 15 out of 18 Class I carcinogens mainly come from occupational environments; as many as 13 out of 18 Class II substances also come from occupational environments. Experts pointed out that the following types of cancer are closely related to work: people engaged in asbestos, arsenic processing, cadmium, coal tar and other related industries are susceptible to lung cancer; people engaged in tanning, aluminum, magenta manufacturing and other industries are susceptible to bladder cancer; practitioners exposed to formaldehyde, asbestos powder are more susceptible to nasopharyngeal carcinoma; and people exposed to benzene, vinyl chloride, X-rays and other industries may suffer from blood tumors.

　　Zuo Wenshu pointed out that "the formation of cancer is the result of a combination of factors." In addition to the environment, bad working and living habits are also important factors in causing cancer. In addition to staying up late, prolonged sedentary behavior at work, excessive stress, fast pace, drinking coffee, strong tea, as well as smoking and drinking, will increase the risk of cancer.

　　So, is it possible to avoid occupational factors that induce cancer? Zuo Wen stated that it is entirely possible. First of all, develop good working habits, less late at night, for those who are often in contact with carcinogens, it is necessary to be diligent in hand washing, bathing, clothing, work with a good mask and other protective gear. Secondly, pay attention to exercise and reasonable diet to improve body resistance. Finally, regular medical checkups.
