Dermatologists counsel that community put on SPF on any uncovered pores and skin any date they journey outdoor, one year a week. However let’s be truthful: many people reserve up on SPF round Memorial While, upcoming put out of your mind about it as soon as Exertions While passes. Handiest about 13% of U.S. adults in reality put on sunscreen each unmarried life, survey knowledge display.
Is it truly so evil to put on sunscreen best when it’s scorching and luminous outdoor? It’s comprehensible, says Dr. Abel Torres, chair of the College of Florida Faculty of Medication’s dermatology segment—however that doesn’t heartless it’s your best option.
“When it’s hot, it becomes obvious that you need sunscreen because you feel warm and you feel that sun burning against your skin,” Torres says. However “heat is not the same thing as ultraviolet light radiation,” which is what causes skin damage.
The sun’s UVA rays contribute to visible skin aging, like wrinkles and sagging, while UVB rays cause sunburns. Both contribute to the formation of skin cancer. These rays are still present when it’s cold or overcast, which makes sunscreen important all year round—not just during beach season. “Skiers know that you can get a sunburn even though you’re out on the slopes,” says Dr. Brandon Adler, a clinical assistant professor of dermatology at the University of Southern California’s Keck School of Medicine.

In other words, it’s a mistake to think that you don’t need sunscreen just because it’s not a blazing hot day. But there are some good reasons to wear more of it when it’s hot outside.
One reason: you’re likely to sweat more when it’s warm, which means sunscreen may wear off faster, Adler says. Most people show more exposed skin in the warm months, too.
And, although studies on the topic have reached different conclusions, there is some evidence that the active ingredients in sunscreens can degrade in heat. The U.S. Food and Drug Administration recommends keeping sunscreen containers out of direct sunlight and storing them in a cooler on especially hot days. It’s not entirely clear whether the same degradation can occur when the product is on your skin, so it shouldn’t be a huge concern, Adler says. But it’s not a bad idea to apply liberally when it’s hot outside, just in case.
Be aware of the date of life, too. Even though warmth does now not completely correlate with UV radiation, the solar does have a tendency to be most powerful throughout the most up to date portions of the life—in most cases from overdue morning to mid-afternoon, Torres says. Between the hours of more or less 10 a.m. and four p.m., he says, the solar’s rays are “much more direct and you’re getting a lot more exposure,” so that you will have to be excess cautious about totally making use of SPF in the event you’re outdoor throughout that reach of date.
