Most people are aware that exposure to ultraviolet (UV) radiation from the sun is the leading cause of skin cancer. Basal cell carcinoma, squamous cell carcinoma, and melanoma are the most common types of cancer in the United States, yet they are often preventable.
You’ve likely developed the healthy habit of applying sunscreen before heading outside in the summer. However, you might not be as consistent during cooler months, on cloudy days, or as the seasons change. This oversight could put your skin health at risk.
Can the Winter Sun Cause Skin Cancer?
Yes, it can. The sun emits harmful UV rays year-round, even during cold or cloudy weather. In fact, some studies highlight a phenomenon known as cloud enhancement of UV radiation, where sunlight reflects off clouds and becomes amplified, increasing the risk of skin damage.
Winter activities like skiing or snowboarding can further increase UV exposure. At high altitudes, UV radiation is more intense because the thinner atmosphere is less effective at blocking harmful rays. Additionally, snow reflects and magnifies UV rays, intensifying their impact. These factors make winter a potentially high-risk season for developing skin cancer.
How to Protect Yourself from Skin Cancer Year-Round
Skin cancer prevention should be a daily priority, regardless of the weather or season. Here are some effective ways to safeguard your skin:
- Use Broad-Spectrum Sunscreen: Choose a water-resistant sunscreen with a sun protection factor (SPF) of 30 or higher to block both UVA and UVB rays.
- Apply Sunscreen Generously: Cover all exposed skin at least 30 minutes before going outside.
- Reapply Frequently: Reapply sunscreen every two hours, and immediately after swimming or sweating.
- Protect Vulnerable Areas: Pay special attention to sensitive areas like your face, ears, and hands. Consider wearing a wide-brimmed hat and using zinc oxide for extra protection.
- By staying vigilant about sun protection, even in the winter, you can significantly reduce your risk of developing skin cancer and keep your skin healthy year-round.
