Sunlight is crucial for vitamin D production and overall health, yet too much UV exposure poses risks of skin cancer and eye cataracts. Protective measures such as wearing shirts, applying sunscreen, and using hats and sunglasses are recommended during peak UV hours. UV levels do not correspond directly with temperature; therefore, skin can burn at any temperature, including on sunny, breezy days. Additionally, UV rays can penetrate clouds, making sun protection necessary even on overcast days.
"UV is important for getting Vitamin D and keeping us healthy, but too much of it can cause skin cancer or eye cataracts," says Dr Michaela Hegglin.
"So slip into a shirt, slop on some sun cream, and slap on a hat and sunglasses during the hottest hours of the day."
"Your skin can burn just as quickly whether it's 30C or 20C," says BBC Weather's Helen Willetts.
"And don't be caught out on cloudy days. UV will still penetrate thin clouds - so even if you don't think it's that sunny, you can still burn."
