You start your day with OJ
Some sour news for citrus lovers: People who consumed citrus, like orange juice or a grapefruit, at least once a day had a 36 percent higher skin cancer risk compared with those who consumed citrus fewer than two times a week, according to a study in the Journal of Clinical Oncology, which followed more than 100,000 adults for 25 years. Citrus foods contain compounds that make skin more photosensitive. But there’s no need to reduce your intake, says lead researcher Abrar Qureshi, MD, MPH, chair of the department of dermatology at the Warren Alpert Medical School of Brown University—just reduce your sun exposure, especially in the few hours after eating citrus. These are strange reasons you got sunburned without realizing it.
You take Viagra
Men who used the drug were 84 percent more likely to develop melanoma over a period of ten years in one JAMA Internal Medicine study. More research is needed to prove a connection, but men over 50 are more than twice as likely as women to develop and die from skin cancer whether they use Viagra or not—so they need to be especially vigilant about sun protection.
