Vitamin D has many health benefits and various studies have proved that it can prevent diseases like heart disease IBS and sleep apnea. And now a new study has said that lower exposure to sunlight and thereby a fall in vitamin D levels in the body can increase one's risk of cancer including leukemia. The researchers analyzed data on the incidence of leukemia in 172 countries and found that people who lived in higher latitudes are two times more likely to develop leukemia than people living near the equator.
