In our Minnesota lifestyle, where outdoor activities are cherished and sun-kissed skin is often celebrated, it’s easy to overlook the potential risks associated with sun exposure and UV radiation. It’s important to understand the impact of sun exposure on our health and the importance of sun safety measures.
Sun exposure and UV radiation pose significant risks to our health, particularly for those who work outdoors. Prolonged exposure to UV rays can lead to various skin issues, including an increased risk of skin cancer.
Patients with skin-related issues are among the most common reasons people seek medical attention. Regular skin checks by healthcare providers, at least annually, for thorough examinations, can catch some issues before they spread.
There are several misconceptions surrounding sun safety:
- You’re safe in the shade. UV rays reflect off other surfaces, so you can get sunburn in the shade if you’re not otherwise protected.
- You need a “base tan.” All changes in skin tone are a result of damage already done; your skin cells change color as a defense mechanism from sun exposure, but it’s not protective.
- Sunscreen only needs to be applied once. Sunscreen needs to be reapplied often to stay effective.
- You don’t need sunscreen on cloudy days. UVA rays penetrate the clouds; you don’t necessarily feel the heat, but the invisible rays are still causing damage.
- Products exist to “reverse sun damage.” Damage made to skin cells during sun exposure is irreversible. The mutations occur to the cells at a DNA level. The only thing you can do is prevent further damage.
- All sunscreens are created equal. It is important to choose a sunscreen with broad-spectrum protection against UVA and UVB rays, with a higher SPF rating being preferable. Reputable sources like the Environmental Working Group (EWG) should be referenced for guidance on sunscreen ingredients to avoid.
Different skin types react differently to UV radiation, with fair to light skin being at a higher risk of damage. Know your individual skin type and take appropriate precautions to minimize sun-related risks for your type.
Sunburn and UV-related skin damage can manifest as age spots, pain, or blistering. You should seek medical attention for prolonged or severe symptoms to prevent further complications.
The best way to mitigate UV radiation risks is avoiding peak sun hours (10am-4pm), covering up with clothing, wearing hats and sunglasses, and using broad-spectrum sunscreen on exposed skin.
UV exposure can have detrimental effects beyond skin issues, including eye damage and overall health implications. Use wraparound sunglasses to protect the eyes and stay hydrated when spending time in the sun.
While enjoying outdoor activities, it’s essential to prioritize protection against the sun’s harmful rays to safeguard our health and well-being. The more sunburn you have had, the greater your risk. The effects compound. Skin Cancer Foundation says one blistering sunburn can double your risk for cancer later in life. SMSC medical providers are available to do skin exams and offer advice—it’s never too late to prevent more sun damage from occurring.
