Vitamin D deficiency is an epidemic nearly everywhere that doesn’t get year-round sunlight and especially with people who work indoors. Many people get seasonal affective disorder during the winter months, but now there’s a new risk. Researchers say that low vitamin D levels may increase the risk for bladder cancer. Since cells activate and respond to vitamin D, this can stimulate an immune response, which can identify and destroy abnormal cells. According to Rosemary Bland, honorary associate professor at the University of Warwick, "More clinical studies are required to test this association, but our work suggests that low levels of vitamin D in the blood may prevent the cells within the bladder from stimulating an adequate response to abnormal cells.”
