How Much Sun Is Beneficial?
When you think of the sun, your first thought might be about the damage it can do. And too much can cause several kinds of serious health issues. But small amounts, especially early in the day before it’s at its brightest, can be good for you in some ways. This answer is different for everyone. It depends on your skin tone, age, health history, diet, and where you live. In general, scientists think 5 to 15 minutes — up to 30 if you’re dark-skinned — is about right to get the most out of it without causing any health problems. You can stay out longer and get the same effect if you use sunscreen. Talk to your doctor about what’s right for you.
