Sure, everyone says to pack sunscreen when you travel.

But how aware are you of the real risks of UV radiation in your destination?

Here’s what you need to know…

UV radiation is a concern wherever, and whenever you travel. But there are circumstances when the risk is even greater.

The higher the sun is in the sky, the greater the exposure. That’s why it’s extra important to protect yourself between 11 a.m. and 4 p.m., especially in the summer.

The closer you are the the equator, the higher the UV radiation levels.

And of course, exposure is still a risk even if it’s cloudy out.

It’s probably common sense that UV rays are more intense when you’re in the water, where the sun is being reflected.

But fresh snow can reflect with even more intensity. That’s why it’s so crucial to wear sunglasses and sunscreen when you’re on the slopes.

And here’s one you may not have known: when you’re at higher altitudes the thinner atmosphere absorbs less UV radiation.

In fact, according to the World Health Organization, for every 3,000 feet increase in altitude, UV levels increase by at least 10 percent.
