How to Protect Your Skin from UV Rays Year-Round

It's easy to think about sun safety during the summer, but ultraviolet (UV) rays can affect your skin every day of the year. Whether you're spending time outdoors, driving to work or enjoying a cloudy afternoon, protecting your skin is an important part of staying healthy.
This guide explains how UV rays affect your skin, offers simple ways to protect yourself year-round and outlines warning signs that shouldn't be ignored.

Understanding UV Rays: UVA vs. UVB

Sunlight produces two types of ultraviolet radiation, each affecting the skin differently:

UVA: These rays penetrate deep into the skin and cause premature aging, wrinkles and sunspots. UVA rays are present all year and can pass through glass.
UVB: This type of radiation affects the outer layer of the skin and can lead to sunburn. UVB intensity peaks in summer and at midday.

Both types increase the risk of skin cancer, which is why broad-spectrum sun protection is a must. It’s helpful to check the UV index, a 0 to 11+ scale included in most weather apps that measures the strength of UV radiation based on time of day and location. You should wear sun protection whenever the index reaches three or higher. Checking it each morning takes seconds and allows you to plan for outdoor activities.

Why UV Protection Isn't Just for Summer

Many people put away the sunscreen after Labor Day, but UV exposure is a year-round threat. Here’s where it may sneak up on you:

Cloudy days: Up to 80% of UV rays can pass through cloud cover, so an overcast sky doesn’t necessarily offer protection.
Winter sun and snow glare: Snow can reflect UV rays, nearly doubling exposure on bright winter days.
Driving and windows: UVA rays pass through most glass, unless treated with UV-blocking film, which means long commutes or sitting at a desk by a sunny window could contribute to skin damage.
High altitudes: UV intensity increases with elevation, so skiing, hiking and mountain travel bring stronger exposure than the same conditions at sea level.

Everyday Sun Protection Tips to Remember

Choose the right sunscreen: Look for a broad-spectrum formula with SPF 30 or higher. Apply it generously about 15 minutes before heading outside and reapply every two hours, or more often if you’re swimming or sweating.
Dress for protection: Long sleeves, pants and tightly woven fabrics shield the skin better than thin or loosely knit materials. Some clothing carries a UPF rating for added protection.
Wear a hat and sunglasses: A wide-brimmed hat shades the face, ears and neck, which are common locations where skin cancer develops. Sunglasses with UV protection help guard the eyes and delicate skin around them.
Avoid peak UV hours: UV radiation is strongest between 10 a.m. and 4 p.m. Plan outdoor activities for earlier or later in the day when possible.
Find shade: Trees, umbrellas and covered areas reduce direct exposure. If your shadow is shorter than you are, the sun is strong enough to damage the skin quickly.

Sun Protection for Kids

Children need extra care in the sun. Their skin is more sensitive than an adult's, and research suggests that blistering sunburns in childhood may significantly increase the risk of skin cancer later in life.

Keep babies under six months out of direct sunlight and protected with shade, lightweight clothing and brimmed hats rather than sunscreen. For babies 6 months and older and children, a broad-spectrum SPF 30+ sunscreen is appropriate. Mineral formulas containing zinc oxide or titanium dioxide are also gentler on sensitive skin.

Know the Signs of Sun Damage

Catching skin changes early can make treatment easier and more effective, so it pays to know what to look for. Dermatologists recommend the ABCDE method for evaluating moles:

Asymmetry: One half doesn't match the other
Border: Edges are irregular or blurred
Color: Shades vary within the same mole
Diameter: Larger than a pencil eraser
Evolving: Changes in size, shape or color

A monthly skin check is easy to do at home. Using full-length and hand mirrors in a well-lit room, examine your entire body, including your scalp, ears, toes and soles of your feet, and note any new or changing developments.

When to See Your Doctor About Skin Issues

Don't wait to get checked if you notice any of the following:

A mole that has changed in size, shape or color
A spot or sore that doesn't heal
A new growth on the skin
An itchy or bleeding patch that crusts over

A professional skin check is quick and painless, and it may catch problems long before they become serious. Even without specific concerns, a baseline exam gives your doctor a reference point for spotting changes at future visits.
