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.

Here's more on how sunlight may be good for your health.
Of course, the sun isn't the only health hazard that presents itself on hot days outdoors. Rising temperatures put people at risk of heat-related illnesses, which include heat exhaustion and deadly heat stroke. Here's what to know about how high temperatures can cause harm.
