5 Things You Need to Know about Sun Rash

You May Be at Increased Risk if You're of Native American Descent

It's usually assumed that Caucasians are at highest risk for conditions related to sun exposure. That's generally a good rule of thumb. In fact, being fair-skinned is known to put a person in jeopardy of sun rash. But the condition can affect all races. In particular, people of Native American descent can have a hereditary predisposition for developing polymorphous light eruption (PMLE). Unlike general sun rash, which usually only lasts a few days, hereditary PMLE can plague a person throughout the summer.

Hereditary PMLE is also known to affect women twice as often as it does men. In general, women are more susceptible to any kind of sun rash.

Other risk factors for sun rash include being under the age of 30 and living in a northern climate. Because inhabitants of northern areas usually have less overall time in the sun, they're more likely to experience an allergic reaction when they're exposed to intense or prolonged sunlight, such as when they visit a tropical or sub-tropical region.
