Taking the right steps to limit your sun exposure is one of the most effective ways to protect your skin and lower your lifetime risk of developing skin cancer. The sun’s ultraviolet (UV) rays can cause serious long-term damage, but with a few simple precautions, you can safely enjoy time outdoors.

For children, exposure should be especially minimized between 12:00 PM and 2:00 PM, as their skin is more sensitive to UV damage.
Shade Is Your Friend
Planning outdoor activities in the shade is a simple and effective way to reduce your UV exposure. Look for tree cover, awnings, or use a wide-brimmed hat or umbrella when natural shade isn’t available.

The daily UV Index reflects the maximum expected UV intensity for that day, usually peaking around midday. You can check it in your weather app or online to plan your activities accordingly.
Your Skin, Your Responsibility
Limiting UV exposure now helps prevent premature aging, sunburns, and skin cancer down the road.
Think of sun safety as a daily habit—like brushing your teeth or wearing your seatbelt.
When we don't protect ourselves, we increase the risk of developing skin cancer. Learn more about skin cancer and what to watch for.
