In the summer months, we’re all well practised in covering exposed skin with sunscreen to protect against the sun’s harmful rays. Come winter, when we’re bundled up in layers of clothing, it’s easy to forget or disregard this important practice. But can you get sunburn in winter? The answer is a resounding yes.
Sunburn can happen in any season when your skin is overexposed to UV rays from the sun. In the summer, it’s true that there are more UV rays because of the angle of the sun, and that combined with more bare skin on display means we are more susceptible to sunburn. However, even though there are less UV rays when the sun is lower in the sky in winter, you can still get burnt. This usually happens when you forget to put sunscreen on exposed areas of skin, like your face and hands, and also when you’re recreating in areas with lots of snow and ice.
Can you get sunburn when it’s cold?
Yes, temperature has no bearing on the level of UV radiation from the sun. Furthermore, cloud coverage might make the sun feel less intense and the day less hot, but the level of UV rays on a cloudy day can be similar to that of a bright, blue sky day.
Does snow increase sunburn?
In particular, when it comes to winter sports, you might actually be more at risk of sunburn. When you’re cross country skiing or snowshoeing, the snow beneath you reflects up to 80% of the sun’s UV rays, meaning that even though the sun is lower, you may be almost doubling your exposure. To add insult to injury, UV exposure gets greater the higher you go in elevation, so if you’re skiing or hiking at high altitude, you’re at an even higher risk. And now you know why skiers in 1980s ski movies always had a white streak of zinc oxide on their noses.
Do I need sunscreen in winter?
If you’ve only ever had mild sunburn, it may not seem like such a big deal. Just some hot, red, itchy skin for a day or two, right? But a bad sunburn can blister, make you quite ill, and in the long run, damage to your skin caused by UV light can lead to skin cancer, which is the most common type of cancer in the US. Protecting your skin from the sun is an important safety aspect to adventuring outdoors in any season.
Although people with paler skin are at more risk of getting burnt, anyone can get skin damage and cancers. The best approach is to make sure that a good sunscreen is part of your regular outdoor kit. It’s helpful to get dressed in your outdoor gear first so you know what skin is going to be exposed, then apply sunscreen to those areas about 30 minutes before you leave the house. Carry your sunscreen with you as you may need to reapply if you’re outside for more than a couple of hours.
Here are some other helpful tips for protecting your skin against the sun:
- Choose sunscreen with an SPF 30 or higher.
- Look for a sunscreen that protects against both UVB and UVA rays.
- Use water resistant sunscreen since you’ll probably be working up a sweat.
- Reapply sunscreen every two hours.
- Don’t forget your ears and part in your hair.
- On very sunny winter days, avoid being outside in the middle of the day if possible.
- Protect your eyes with UV blocking sunglasses.
- Dress in hiking pants and long sleeved base layers that have UV protection.
- If you're not wearing a helmet or beanie, wear a hiking hat with a brim to offer shade.
