Even though many people are pretty indoorsy today, the outside world can still have a huge impact on your health. For instance, the things that happen to your body after only 10 minutes in the sun are a bit surprising. The closest star to the Earth can affect you in some very real ways.
Before diving in, it's helpful to know a little more about the sun and its rays. For starters, the sun produces ultraviolet (UV) light, which falls outside the spectrum visible to the human eye, according to NASA. Even though people can't see this shorter wavelength of light, it can still affect the body in some real ways. For instance, exposure to UV radiation is a risk factor for skin cancer, and the sun is the main source of these UV rays, according to the American Cancer Society. To help people avoid this risk, the UV Index Scale indicates how potentially dangerous the sun's UV rays are on a given day, according to the United States Environmental Protection Agency. For instance, a day with a low UV index may present a low risk for the average person, whereas a very high UV index reading means unprotected sun exposure could be dangerous. For the most part, the body needs protection from UV rays.
But this isn't to say that everything about the sun is so negative for the human body. Read on to see how catching some rays may affect your health in both positive (and not-so-positive) ways.
