Common sunscreen myths, debunked

Vox: “Despite the extremely well-established science linking sun exposure to skin cancer, bad sun safety advice on social media simply will not stop — and a lot of people are buying it. In several recent surveys, between one and three out of every 10 adults believed a range of falsehoods about sunscreen and sun exposure; a few days ago, the Cleveland Clinic felt compelled to plead with people not to do something called “beer tanning.” Young people are especially likely to believe misleading messages about sun exposure, although they don’t have a monopoly on misunderstanding — or miscommunicating — the science; middle-aged podcast hosts (and frequent peddlers of pseudoscience) Joe Rogan and Andrew Huberman have also done their share of spreading inaccurate information. Many experts also point to TikTok as the source of the wildest rumors and speculation about sunscreen. Sun safety fallacies have been around for decades, but they got a boost five years ago after a flurry of confusing actions and statements on sunscreen by the Food and Drug Administration. Then, last year, multiple aerosol products, including a few sunscreens, were found to be contaminated by benzene — a known carcinogen — leading to widespread recalls. Additionally, a growing body of science suggests there are benefits to getting a little sun, although not all countries’ public health authorities embrace that science equally. A recent article in the Atlantic highlighted evidence suggesting a range of benefits associated with UV radiation. While a consortium of Australian public health groups recommends a modest amount of sun exposure to residents on the basis of some of that evidence, American public health authorities don’t. It’s no wonder so many people are confused about what’s true and what’s not about sunscreen. Understanding what’s behind some of the more common misleading statements about sun safety — and why people fall for them — can help.”
