Can You Get Skin Cancer in the Snow?
When temperatures drop and snow covers the landscape, most people stop worrying about sunburn, let alone skin cancer. But is winter really a time when you can relax about sun safety? Whether you're a skier, snowboarder, winter hiker, or someone who walks to work on chilly mornings, this post unpacks everything you need to know about skin cancer risk in the snow—and how to stay protected.
Why Winter Doesn't Mean UV Safety
Most of us associate sunburn and skin damage with sweltering, sunny days at the beach or pool. Cold weather and winter clouds seem like natural barriers against UV rays, but the truth is more complicated.
Understanding UV Radiation
Ultraviolet (UV) rays are the main environmental cause of skin cancer, and they're present every single day—even when the weather is cold or cloudy. UV radiation can penetrate clouds and even some clothing, putting outdoor enthusiasts at risk year-round.
Dr. Susan Chon, M.D., associate professor at MD Anderson’s Department of Dermatology, notes that "if you’re outside, any uncovered areas of your body are exposed to UV rays." The American Cancer Society reports that over two million Americans are diagnosed with skin cancer each year, making it the most common cancer in the U.S.
Snow Reflection Amplifies UV Rays
Here's where winter gets tricky. Fresh, white snow can reflect up to 80% of UV rays, effectively doubling your exposure. That means UV can hit your skin from above and below, increasing the likelihood of sunburn (and long-term skin damage). A day on the ski slopes can cause just as much skin damage as a day at the beach.
At higher altitudes, the air is thinner and the protective atmosphere blocks less radiation. For every 1,000 feet above sea level, UV exposure jumps by about 4–5%. The combination of reflection and altitude means that winter athletes, mountain hikers, and even commuters in snowy cities face significant risk.
Who Is Most at Risk in Snowy Settings?
Certain groups should be extra cautious when outdoors in snowy or high-altitude conditions:
- Skiers and Snowboarders: Prolonged exposure at altitude, compounded by reflection from snow.
- Children Walking to School: Kids often spend time outside during peak UV hours and may not practice sun safety.
- Outdoor Workers: Snow removal crews, construction workers, and others who work outside daily.
- Hikers and Snowshoers: Even short hikes can lead to major exposure.
- Winter Commuters: Anyone who spends time outdoors, especially during midday.
People with fair skin, a history of sunburns, or family history of skin cancer are especially vulnerable, but everyone can be affected.
How to Protect Yourself from UV Exposure in Snow
Worried yet? The good news is that skin cancer is one of the most preventable cancers. Here are practical ways to defend your skin—even when snowflakes are falling.
Use Sunscreen, No Matter the Temperature
- Opt for broad-spectrum (UVA/UVB) sunscreen with SPF 30 or higher.
- Apply liberally to clean, dry skin at least 30 minutes before going outside.
- Pay special attention to overlooked spots like your nose, cheeks, ears, neck, and even under your chin (reflection hits here, too).
- Use sunscreen with zinc oxide for sensitive areas.
- Reapply every two hours, or immediately after sweating or wiping your face.
- Don’t forget a SPF 30+ lip balm for your lips.
Dress for Defense
- Choose UPF 50+ clothing to cover arms, legs, and neck. Many jackets, pants, and even face masks now come with built-in sun protection.
- Wear a wide-brimmed hat or a helmet with a visor.
- Use gloves, and consider a face mask or balaclava for extra snowy days.
- Sunglasses or goggles with 100% UV protection will safeguard sensitive eye areas and reduce the risk of snow blindness.
Time Your Exposure
- Seek shade between 10 a.m. and 4 p.m., when UV rays are most powerful—even in winter.
- If possible, schedule outdoor activities for early morning or late afternoon.
Get to Know Your Skin
- Check your skin monthly for new or changing moles using the ABCDEs of melanoma:
-
- Asymmetry
- Border irregularity
- Color variation
- Diameter (>6mm)
- Evolving size, shape, or color
- If you’re at higher risk, see a dermatologist annually.
Debunking Common Myths About Winter Sun
Myth 1: “If it’s cloudy or snowing, there’s no risk.”
Fact: Up to 80% of UV rays can pass through clouds. Some studies show that thin cloud cover can actually increase UV levels by reflecting sunlight within the cloud itself.
Myth 2: “You don’t need sunscreen if you have darker skin.”
Fact: While darker skin has more melanin (which offers some protection), skin cancer can and does occur in people of all skin tones.
Myth 3: “It’s too cold to get sunburned.”
Fact: Temperature has no effect on UV levels. You can get burnt on a freezing day, especially with reflection from snow.
Myth 4: “I’ve never been sunburned in winter, so I won’t get skin cancer.”
Fact: Cumulative UV exposure is a major risk factor for all types of skin cancer. Sun damage isn’t always visible as a burn.
Why Sun Safety Matters Every Day
When the temperature dips and days are gray, it’s tempting to skip the sunscreen or leave skin exposed. But winter is not a time to relax your sun safety habits. Even if you only spend short periods outdoors, unprotected skin accumulates sun damage over time.
Malignant melanoma, the deadliest form of skin cancer, is linked to both occasional severe sunburns and day-to-day UV exposure. Other common types, like basal or squamous cell carcinoma, are also influenced by chronic sun exposure.
Regular use of sunscreen and protective clothing can dramatically reduce your risk—not just of cancer, but also of premature aging, sun spots, and eye damage.
Stay Protected and Enjoy Winter Outdoors
Enjoying snow sports, brisk walks, or just running errands in winter doesn’t have to put your skin at risk. Follow these practical steps:
- Make sunscreen and UPF clothing a routine—not an exception.
- Protect your lips and eyes.
- Be vigilant about skin checks.
- Educate friends and kids about year-round sun safety.
A few simple changes to your winter routine can keep your skin healthy, so you can enjoy the outdoors for years to come.
