Summer Health Myths, Busted: What You Really Need to Know
Summer is the perfect time to get outside, soak up some sunshine, and enjoy the longer days. But along with warm weather comes a handful of health myths that have been passed around for years. Some sound convincing, while others might make you second-guess what’s actually true.
Many of these common beliefs are easy to clear up. Understanding the facts can help you stay safe and enjoy everything summer has to offer without unnecessary worry.
Think SPF 50 gives you way better protection than SPF 30? Let’s bust some of the most common summer health myths with Madison Odom, PA-C and Ofure Harrison, MD.
Myth: SPF 50 Is Way Better Than SPF 30
It’s easy to assume that the higher the number, the stronger the protection. While SPF 50 does block slightly more UV radiation, the difference is smaller than many people think. SPF 30 blocks about 97% of Ultraviolet B (UVB) rays, which are responsible for causing sunburns, while SPF 50 blocks about 98%. The most important factor isn’t the SPF number; it’s how often you reapply it. Sunscreen should be reapplied every two hours, and even sooner if you’re swimming or sweating. Using enough sunscreen and reapplying regularly provides much more protection than choosing a higher SPF.
Myth: You Have to Wait 30 Minutes to Swim After Eating
Many of us grew up hearing that swimming right after eating could cause dangerous cramps. In reality, there’s no medical evidence showing that swimming on a full stomach is harmful.
Your body is capable of digesting food while you’re active, including while swimming. While some people may feel slightly uncomfortable exercising right after a large meal, it doesn’t pose a medical risk. The best approach is simple: listen to your body and get in the water when you feel ready.
Myth: You Don’t Need Sunscreen on a Cloudy Day
Cloud cover might make the sun feel less intense, but it doesn’t eliminate harmful UV exposure.
Up to 80% of UV rays can still pass through clouds, which means your skin can still burn or experience damage even when the sun isn’t visible. If you’re spending time outdoors, sunscreen is an important part of protecting your skin, regardless of whether the sky is clear or overcast.
Myth: Tanning Gives You a “Healthy Glow”
A tan may look like a sign of summer, but it’s actually your skin responding to damage caused by ultraviolet (UV) radiation. When skin darkens, it’s producing extra pigment to try to protect itself from DNA damage caused by UV exposure. This means there’s no such thing as a “healthy tan.”
Tanning beds can also pose serious risks. In many cases, they expose the skin to concentrated UV radiation, which can increase the risk of premature aging and skin cancer. Protecting your skin with sunscreen, protective clothing, and shade is the safest way to enjoy the sunshine.
