Sunburns: What to Know
The risks of getting too much sun are as clear as day. The sun's ultraviolet (UV) rays not only damage skin cells and cause sunburns, but they also are a proven human carcinogen, meaning they cause cancer, according to the World Health Organization. Indeed, the vast majority of cancer cases come from exposure to UV rays, the Skin Cancer Foundation says. Here's a look at how the sun does its damage, and why sunburns are a problem.

When it comes to sun safety, sunscreen is one of your most important lines of defense. But the labeling on sunscreen bottles has changed in recent years, so it's important to make sure your sunscreen knowledge is up-to-date before slathering your skin with lotion. For example, grabbing the first bottle you find in your cabinet may not provide the best protection, as sunscreens do expire. And the language on the labels does matter, so make sure you know what to look for to ensure you stay safe in the sun.

It's not just sunscreen…
Although sunscreen is essential for blocking the sun's harmful rays, it's not the only way to boost your protection. Your clothes and sunglasses can also help keep you safe from the sun. And simple steps like avoiding the sun during the middle of the day are beneficial as well. Here's a look at other ways to protect yourself from the sun.

But the sun isn't all bad…
When it comes to the sun, it can be difficult to balance the good and the bad. But there are health benefits associated with the sun's rays — indeed, completely avoiding the sun at all costs can be harmful. Sunlight is the best source of vitamin D, and it's difficult to get enough of this vitamin through food sources alone. Vitamin D is produced when UV rays hit the skin, causing a chemical reaction. Here's more on how sunlight may be good for your health.
