Many studies have suggested that a lack of sunlight is linked to cardiovascular disease. In 2013, scientists in Denmark found that sunlight may actually protect the heart. When they analyzed more than 4 million medical records, they discovered that people who’d been diagnosed with skin cancer were actually less likely to have had a heart attack (or to have died from any cause) over the course of the study.

“As skin cancer is a marker of substantial sun exposure, these results indirectly suggest that sun exposure might have beneficial effects on health,” the study authors wrote. However, they caution that this does not prove a cause-and-effect relationship, and that sunlight’s effects on heart health should be studied more directly.
