In 2026, skin cancer is the most common cancer in the U.S. and 1 in 5 Americans develop skin cancer before the age of 70. Most skin cancers are linked to ultraviolet (UV) rays which come predominately from sun exposure.
How can Polk County residents combat the dangers of sun exposure while living in a state where the sun is not easily avoided?
The key is to prevent sun damage to the skin, and one of the best prevention strategies is sunscreen. Wearing sunscreen is one of the most widely recommended tips for preventing sun damage. Sunscreen acts as a protective barrier between your skin and the sun’s UV rays, which are the driving force behind most skin cancers. Over time, steady exposure builds into the kind of cumulative damage that can lead to both visible aging and cancer.
Choosing a sunscreen is easier than it sounds. Dermatologists recommend using a broad-spectrum formula with an SPF of at least 30, which shields the skin from both types of UV rays: UVB, which burns the surface, and UVA, which penetrates more deeply and accelerates aging while also contributing to cancer risk. Sunscreen comes in many forms such as lotions, sprays, sticks, and gels, and the best one is the one you’ll use consistently.
Once you have the right sunscreen, the next step is applying enough of it. Most people underestimate how much they actually need, which cuts the level of protection significantly. A good rule of thumb for the body is about two tablespoons total. The face and neck alone need the amount it takes to lightly cover two fingertips. Sunscreen should be applied 15 to 30 minutes before going into the sun, giving it time to bind properly to the skin. Because sunscreen naturally wears off, breaks down, or rubs away, reapplying every two hours is important, especially if you’re sweating or swimming.
Sunscreen isn’t just for beach days or long outdoor outings. In Florida, daily UV exposure adds up whether you intend to spend time outside or not. Many people don’t realize just how much time they accidentally spend in the sun driving with the windows down, walking pets, gardening, or simply sitting near bright windows.
Sun protection is for everyone. Skin damage happens silently and gradually, and preventing it is far easier than treating the effects later. Sunscreen, paired with simple habits like seeking shade when possible and wearing protective clothing during peak sunlight hours, forms a strong defense against skin cancer.
Making wearing sunscreen a daily habit is one of the simplest and most effective ways to safeguard your skin health while still enjoying the Florida sunshine.
