When the colder months roll in, many people assume they no longer need to worry about sun protection. However, this couldn’t be further from the truth. Ultraviolet (UV) rays can still damage your skin in the winter, increasing your risk of skin cancer, premature aging, and sunburn. Whether it’s cloudy, snowy, or chilly, protecting your skin from the sun’s harmful rays should be a priority all year long.
In this guide, let's explore why sun protection is essential in winter and offer practical tips for shielding your skin from UV damage beyond just wearing sunscreen.
Do You Need Sun Protection in Winter?
Absolutely! Even though it’s colder, UV rays are still present and can harm your skin. UVA rays, in particular, are present year-round and can penetrate clouds and glass, reaching your skin regardless of the temperature. While UVB rays, which cause sunburn, may be weaker during winter, UVA rays are the culprits behind premature aging, wrinkles, sunspots, and skin damage that can lead to skin cancer.
Here are key reasons why sun protection is essential during winter:
UV Rays Penetrate Clouds and Windows
Clouds may cover the sun, but they don’t fully block UV rays. In fact, up to 90% of UV rays can penetrate through clouds and reach your skin. Similarly, if you’re spending time indoors near windows, UVA rays can still come through the glass. Whether you’re outside on a gloomy day or sitting near a window, you’re still exposed to UV radiation.
Snow Reflects UV Rays
Snow can significantly increase your exposure to UV radiation. Fresh snow reflects up to 80% of UV rays, meaning that even though the sun might feel less intense, the rays bounce off the snow and back onto your skin. This makes skiing, snowboarding, or even walking in the snow a potential source of UV damage. In these environments, sun protection is even more critical to prevent burns and long-term skin damage.
UV Exposure Increases at Higher Altitudes
If you’re hitting the slopes or spending time at higher elevations, your UV exposure will be higher than at sea level. The higher the altitude, the thinner the atmosphere, which allows more UV rays to reach your skin. In fact, UV radiation increases by approximately 4-5% for every 1,000 feet you ascend, and this effect can be even greater depending on your location in the world. This makes it essential to layer your sun protection if you’re at high altitudes in the winter.
UVA Rays Contribute to Premature Aging Year-Round
While UVB rays are responsible for sunburns, UVA rays penetrate deeper into the skin and are a leading cause of premature aging. These rays cause fine lines, wrinkles, loss of elasticity, and hyperpigmentation. Even in winter, cumulative UVA exposure can speed up the aging process and increase your risk of skin cancer, making year-round sun protection critical.
Skin Cancer Doesn’t Take a Break in Winter
The risk of skin cancer isn’t limited to summer. UV damage builds up over time, meaning that every exposure adds to the cumulative risk of developing skin cancer. Whether you’re hiking in the winter, driving with the sunroof open, or even just running errands on a cloudy day, you’re still at risk. By staying diligent with sun protection in the winter, you help reduce your overall exposure and long-term skin damage.
How to Protect Your Skin from UV Rays in Winter
Beyond sunscreen, there are many effective ways to protect your skin from UV rays during the colder months. Here are some essential tips for maintaining sun safety all year round:
Wear UPF Clothing
UPF (Ultraviolet Protection Factor) clothing offers continuous protection against UV rays without needing to reapply like sunscreen. Whether it’s a UPF-rated jacket, long-sleeve shirts, or scarves, sun-protective clothing blocks both UVA and UVB rays, making it a smart choice for year-round use.
UPF 50+ clothing blocks at least 98% of UV radiation, making it a reliable choice for outdoor winter activities like hiking or snow sports.
Use Broad-Spectrum Sunscreen
Sunscreen is still important in the winter, but you need to make sure you’re using a broad-spectrum sunscreen that protects against both UVA and UVB rays. Look for an SPF of at least 30 to provide adequate protection.
Apply sunscreen generously to any exposed skin, such as your face, neck, and hands. Remember to reapply every two hours, especially if you’re skiing, sledding, or spending time outdoors.
Protect Your Lips and Hands
The cold weather can dry out your lips, and they’re especially vulnerable to UV damage. Use a lip balm with SPF to protect them from both the sun and the elements. The skin on your hands is also delicate and often exposed in the winter, so make sure to apply sunscreen to your hands as well or wear gloves with UV protection.
Wear Sunglasses with UV Protection
Snow and ice reflect UV rays, which can harm your eyes. Sunglasses with UV protection are a must to shield your eyes from the damaging effects of UV radiation. Choose sunglasses that block 100% of UVA and UVB rays, and consider wraparound styles for extra coverage.
Wear a Wide-Brimmed Hat
Even in winter, the sun can still reach your scalp, neck, and face. Wearing a wide-brimmed hat can help protect these vulnerable areas from direct sun exposure. For added protection, look for hats made with UPF-rated fabric.
Check the UV Index Daily
Just because it’s cold doesn’t mean the UV Index is low. The UV Index measures the strength of the sun’s UV rays on a scale of 1 to 11+. Make it a habit to check the UV Index each day, as it will guide how much sun protection you need. Even on cloudy days, the UV Index may still be moderate or high, depending on where you live.
The Bottom Line: Why Sun Protection Is Essential, Even in Winter
Just because the weather is colder doesn’t mean your skin is safe from the sun’s harmful rays. UV rays are present year-round, and winter conditions can even increase your exposure to damaging radiation. Wearing UPF clothing, sunscreen, and sunglasses, and checking the UV Index regularly, are essential steps to protect your skin from sunburn, premature aging, and skin cancer.
Don’t forget: Sun protection isn’t just for summer. By keeping your skin protected all year long, you’ll enjoy healthier, more resilient skin no matter the season.
