UV Safety Month: Protecting Your Skin Under the Sun
July is UV Safety Month, reminding us to be mindful of the sun’s powerful rays and how to protect our skin while enjoying the outdoors. Ultraviolet (UV) radiation from the sun can lead to skin damage, premature aging, and skin cancer. Understanding UV radiation is key to maintaining healthy skin. We’ve partnered with Dartmouth Health Children’s on this important topic. Take a look at their Tiny Tips video below for some essential tips on how to protect yourself and your family from the sun.
What Is UV Radiation?
UV radiation is an invisible form of energy emitted by the sun, penetrating the skin and causing damage. There are three types of UV rays:
- UVA: Penetrates deeply, causing aging and wrinkles.
- UVB: Affects the outer skin layers, causing sunburns.
- UVC: Mostly absorbed by the Earth's atmosphere and does not reach the surface.
While some UV exposure is necessary for vitamin D production, excessive exposure can be harmful, making sun safety crucial, especially in summer.
How to Protect Yourself in the Sun
Here are five essential tips:
- Apply Sunscreen Regularly: Use broad-spectrum sunscreen with at least SPF 30, applying it 15 minutes before sun exposure and reapplying every two hours.
- Seek Shade: Stay in the shade during peak UV hours from 10 a.m. to 4 p.m. to minimize exposure.
- Wear Protective Clothing: Use long-sleeved shirts, wide-brimmed hats, and sunglasses that block 99-100% of UV rays.
- Be Aware of Reflections: Surfaces like sand, water, and snow can reflect UV rays, increasing exposure.
- Stay Informed: Watch educational videos like "Tiny Tips" featuring Dr. Katherine Su on recommended sun protection practices.
