Protect Skin From Sun Through Windows: Driving & Home

How can I protect my skin from sun exposure through windows while driving or sitting near glass?

Glass can make sunlight feel less intense, but it doesn’t block all the rays that affect skin. Most standard car and home windows filter much of UVB (the ray that causes sunburn), yet a significant amount of UVA can still pass through. UVA penetrates deeper into the skin, contributes to premature aging, and can play a role in skin cancer risk—so daily protection matters even when you’re indoors or behind the wheel.

Start with the right daily sunscreen

Use a broad-spectrum sunscreen labeled SPF 30 or higher on all exposed areas (face, neck, ears, hands, and forearms). If you’re driving often, don’t forget the left side of the face and arm, which commonly get more exposure in the driver’s seat. Apply about 15 minutes before heading out, and reapply every 2 hours if you’re in prolonged daylight or sweating—more often if you wipe your skin.

Add physical barriers that stay put

Clothing is a reliable layer that doesn’t wear off. Long sleeves or UPF-rated tops, lightweight driving gloves, and a broad-brim hat (when not obstructing your view) can help reduce exposure. Sunglasses labeled UV400 or 100% UV protection protect the delicate skin around the eyes and support eye health.

Upgrade window protection

For driving, consider professional UV-blocking window film where legal. Many quality films are designed to reduce UVA transmission significantly without making the glass overly dark. At home or the office, UV-filtering window film, UV-blocking shades, or curtains can cut the amount of UVA reaching skin during long periods near windows.

Adjust your habits when possible

Small changes help: sit farther from large windows, rotate seating positions during long drives, and try to avoid peak sun hours when practical. These steps reduce cumulative exposure—the kind that adds up over years.

FAQ

Do I need sunscreen indoors if I work next to a window?

If you spend hours near a bright window, daily broad-spectrum sunscreen is a smart precaution because UVA can pass through glass and contribute to long-term skin damage.
