When winter arrives, many people stash away their sunscreen, thinking the cold weather and cloudy skies protect them from the sun’s harmful rays.
But here’s a surprising fact: your skin needs sun protection all year round, including during the chilly winter months.
1. UV rays are still active in winter
Sunlight contains ultraviolet (UV) rays, which come in two main forms — UVA and UVB. While UVB rays, which cause sunburn, are stronger during the summer, UVA rays penetrate the skin every day of the year, regardless of the season or weather. These rays contribute to premature aging and increase the risk of skin cancer.
2. Snow and altitude make winter sun more intense
If you love outdoor winter sports or live in snowy or mountainous regions, you should be especially cautious. Snow reflects up to 80% of UV radiation, which means your skin gets hit by both direct and reflected rays — effectively doubling your sun exposure. Similarly, higher altitudes increase UV intensity, making sun protection crucial even when temperatures drop.
3. Protect your skin from premature aging
UVA rays penetrate deep into the skin, breaking down collagen and elastin, which leads to wrinkles, fine lines, and sagging skin — a process called photoaging. Wearing sunscreen daily is one of the best ways to preserve your skin’s youthful look.
4. Sunscreen helps prevent skin cancer
Cumulative exposure to UV rays is the leading cause of skin cancer. Regular use of broad-spectrum sunscreen reduces your risk by shielding your skin from harmful radiation.
5. Don’t forget indoor exposure
UVA rays can pass through glass windows, so if you spend a lot of time near windows at home, work, or in your car, your skin is still vulnerable. Applying sunscreen daily provides an extra layer of protection.
