The sun has been the source of sunburn, but a recent study suggests there’s no need to apply sunscreen after spending the night outdoors.
Researchers from the University of Southern California surveyed the health of 1,852 college students about their sunscreen use, and found the average sunscreen user only used it on the day they bought their sunscreen.
The study found only 10% of the students said they spent the night with sunscreen on, with only one student saying they used it at least once a day.
Instead, the students were asked to apply their sunscreen only the next day, and the majority of them said they applied sunscreen every day.
The researchers said it’s likely this is because sunscreen helps to protect the skin from the sun’s harmful rays.
“We see sunscreen as a way to protect ourselves from harmful UV rays and that’s why we recommend that people apply it only once a week,” Dr. Andrew Hochberg, an associate professor of dermatology and ophthalmology, said in a statement.
“Sunscreens may not be effective for everyone, but for those who can afford to spend the extra time and money to get their sunscreen, they can expect to benefit from the protective properties.”
The study found that students who used sunscreen at least weekly were significantly less likely to have sunburn.
The results are published in the journal PLOS One.
