Even though winter may still be lingering, warmer days are on the way. As the weather improves, many people naturally spend more time outdoors. What is often overlooked, however, is how the sun’s ultraviolet (UV) rays affect the skin each time it is exposed. Whether you get a tan or a sunburn, UV radiation can have a cumulative impact on skin health. Here is a closer look at what happens when the skin is exposed to the sun and why protective habits matter.
Sunburns and UV Exposure
Many people have experienced a sunburn at some point. A sunburn occurs when the skin is exposed to more UV radiation than it can safely handle, affecting the outer layers of the skin. More intense exposure can lead to deeper irritation and damage within the skin’s layers.
Over time, repeated or severe sunburns may contribute to long-term changes in the skin. These changes can vary from person to person and may include dryness, uneven pigmentation or areas of roughness. The skin also becomes less efficient at repairing itself as we age, which can make it more vulnerable to ongoing UV exposure.
Why Sun Protection Matters
Your lifetime pattern of sun exposure—including how often you burn and how intense those burns are—can influence how your skin responds to UV radiation over time. Because the skin has a limited ability to recover from repeated injury, adopting daily sun protection habits can help support healthy skin as you age.
Ways to Help Protect Your Skin
Simple measures can make a meaningful difference in reducing UV exposure:
- Apply a broad-spectrum sunscreen with SPF 30 or higher before going outdoors
- Reapply sunscreen regularly, especially after swimming or sweating
- Wear UPF-rated clothing, hats and sunglasses for added protection
- Seek shade during peak UV hours
- Be mindful of how long you spend in direct sunlight
As warmer months approach, planning ahead—such as checking your sunscreen supply and setting aside protective clothing—can help you stay consistent with sun-safe habits. If you have concerns about sun damage or notice changes in your skin, a healthcare professional can provide guidance specific to your needs.
