The importance of suncare during winter

Suncare during winter

Have you ever wondered whether you need sunscreen in winter? Suncare is associated with summer and vacations, but contrary to popular belief, sun protection is just as crucial in winter as it is in summer. Understanding the importance of suncare in winter is essential for protecting your skin from the sun’s harmful rays and maintaining healthy skin all year round. Here’s why you should not pack away that sunscreen in winter.

UV rays don’t take a break

There are two types of UV rays that exist – UVA and UVB rays. In winter, UVB rays are less intense compared to summer, but UVA rays remain consistent throughout the year. These rays can penetrate clouds and windows, meaning that even on overcast days or when you’re indoors near a window, your skin is still exposed to potential harm.

Low moisture levels and wind are tough on skin

You may have noticed that your skin becomes drier and more sensitive in cold weather. During winter, the air has less humidity and wind speeds often increase, which continuously strips moisture from your skin. This dryness accentuates every wrinkle and fine line, making your skin more prone to cracking or tearing, which can increase the risk of infection. Using sunscreen in winter can help replenish some of your skin’s lost moisture.

Intense UVA/UVB rays

In winter UVA/UVB rays from the sun raise your risk for skin damage. If you plan to be outdoors, applying sunscreen is essential. Choose a broad-spectrum sunscreen with an SPF of at least 30 and apply it to all exposed skin areas for effective protection – even if you plan to spend most of your time indoors.

The ozone layer is thinnest in winter

The stratosphere is a layer of protective gases surrounding the planet, named for its stratified (layered) structure. Near the top of the stratosphere, furthest from Earth, lies the ozone layer, which absorbs and reflects UV rays from the sun. Ozone production occurs more rapidly in warm temperatures and more slowly in cold ones. Consequently, the ozone layer is thinner at the Earth's poles, where temperatures are extremely low, and it is thinnest elsewhere during the cold winter months. This means that even though the sun doesn’t feel as hot in winter, you are actually exposed to more intense UV rays.

Winter conditions can strip sunscreen more quickly

During summer at the beach or swimming pool, you can feel your sunscreen melting away due to the heat and sweating. In winter, even though you're not sweating, harsh conditions can erode your sunscreen even faster. Strong winds can wear away sunscreen and reduce its effectiveness. Therefore, applying one layer of sunscreen in the morning isn't always sufficient. It's recommended to reapply your sunscreen every two hours when you're outdoors and immediately after sweating.

Conclusion

Despite common misconceptions, the winter months pose significant risks to your skin due to consistent UVA rays and the thinner ozone layer. Additionally, winter's harsh conditions can deplete moisture and strip away sunscreen, necessitating regular reapplication. By understanding and implementing proper suncare practices during winter, you can protect your skin from the sun's harmful rays and maintain its health and vitality throughout the year. So, make your sunscreen a daily essential, no matter the season.
