For a lot of us, sun protection feels tied to very specific moments: beach vacations, pool days, summer heat waves, maybe that one time we remembered sunscreen because we knew we’d be outside all afternoon. But skin cancer prevention is often shaped by something much less dramatic: the ordinary moments we barely think about at all.
Walking the dog. Driving to work. Sitting near a sunny window. Watching your child’s soccer game. Running errands on a cloudy afternoon. Spending a few extra minutes outside every day may not feel significant in the moment, but over time, those small exposures can add up.
According to the Centers for Disease Control and Prevention (CDC), ultraviolet (UV) radiation from the sun is one of the most preventable risk factors for skin cancer, which remains the most common cancer in the United States. While a sunburn may fade after a few uncomfortable days, cumulative UV damage can build over years and contribute not only to premature skin aging, but also to several forms of skin cancer. That is part of why dermatologists emphasize consistency over perfection.

The conversation around sunscreen has traditionally centered on vacations and long summer days outdoors, but experts say sun protection is about everyday habits. The American Academy of Dermatology (AAD) recommends using broad-spectrum sunscreen that protects against UVA and UVB rays, along with additional protective measures like sunglasses, hats, and protective clothing.
Both UVA and UVB rays can damage the skin, though they affect it differently. UVB rays are mostly associated with sunburns, whereas UVA rays penetrate deeper into the skin and are linked to premature aging. Importantly, UVA rays can still pass through clouds and glass, meaning exposure can happen even during overcast weather or while indoors near windows.
One of the most persistent misconceptions surrounding sunscreen is the belief that people with darker skin tones do not need it. While melanin does offer some natural protection against UV radiation, dermatologists stress that people of all skin tones can experience sun damage and develop skin cancer. In some cases, skin cancers in darker-skinned individuals are diagnosed later because warning signs may be overlooked or dismissed.
Another common myth is that sunscreen only matters on sunny days. UV rays can still penetrate cloud cover, which means cloudy weather does not eliminate exposure risk. Health organizations like the CDC and FDA continue to recommend regular sun protection practices even when temperatures are cooler or the sky looks overcast.

At the same time, public health experts continue to address growing online misinformation surrounding sunscreen safety. The ADA maintains that sunscreen remains an important part of skin cancer prevention and encourages anyone with questions about ingredients or sensitivities to speak with a board-certified dermatologist.
For most adults, experts recommend:
- Using a broad-spectrum sunscreen with SPF 30 or higher
- Reapplying sunscreen every 2 hours when outdoors
- Wearing sunglasses and wide-brimmed hats
- Seeking shade during peak UV hours
- Avoiding indoor tanning beds
- Remembering commonly missed areas (eg, ears, scalp, neck, hands, and tops of the feet)
Importantly, sun protection does not need to be all-or-nothing to be worthwhile.
Keeping sunscreen in your bag. Applying it before your morning commute. Throwing on a hat before an afternoon walk. These are small habits, but they can help reduce cumulative UV exposure over time.
And when it comes to skin cancer prevention, those ordinary everyday choices matter more than many people realize.
