Who doesn’t love a sunny day? Whether you’re heading to the beach, going for a hike, or just enjoying a walk outside, the sun can feel amazing. But before you soak up those rays, it’s important to remember that too much sun exposure can be harmful to your skin—and even increase your risk of skin cancer.
Our team of 600+ doctors and scientists at the Masonic Cancer Center (MCC), University of Minnesota wants to help you enjoy the sunshine while keeping your skin safe. Here’s what you need to know about sun protection and why it’s so important.
Why does sun safety matter?
Skin cancer is the most common type of cancer in the U.S., and anyone—no matter their age or skin color—can get it. The biggest risk factor? Exposure to the sun’s ultraviolet (UV) rays. These rays damage skin cells, which can lead to changes that turn into cancer over time.
Some signs of skin cancer include:
- Moles or spots that change in size, shape, or color
- Sores that don’t heal
- Raised, red patches or fast-growing bumps
- Dark patches on the palms of hands, soles of feet, or under nails
If you notice anything unusual on your skin, it’s important to see a dermatologist or your primary care provider as soon as possible. Check out this guide for more details on the risk factors, signs and symptoms, and top ways to prevent skin cancer.
How can you protect your skin?
The good news? Skin cancer is one of the most preventable cancers. By taking a few simple steps, you can enjoy the sun while keeping your skin safe.
1.Wear sunscreen—every day!
A good sunscreen is your skin’s best friend—no matter what your skin tone is. And while some experts have preferences between a mineral or a chemical-based sunscreen, the best sunscreen is the one you will actually use! Choose a sunscreen with at least SPF 30, and apply it 15 minutes before going outside. Reapply the sunscreen every two hours, especially if you’re sweating or swimming.
2. Limit your time in the sun
The sun’s rays are strongest between 10 a.m. and 4 p.m. If you’re outside during these hours, try to find shade whenever possible. A tree, an umbrella, or a wide-brimmed hat can help block UV rays.
3. Cover up
Wearing protective clothing can help keep your skin safe. Lightweight, long-sleeved shirts, pants, and wide-brimmed hats provide extra protection. And don’t forget your sunglasses—your eyes need protection too!
4. Skip the tanning bed
Indoor tanning beds expose your skin to harmful UV radiation, increasing your risk of skin cancer. A natural glow is always the safest option!
5. Know your skin
Perform regular skin checks to look for any changes. If you notice a new spot or a mole that’s changing, growing, or bleeding, don’t wait—schedule a skin check with your doctor.
