Can You Get Skin Cancer from Driving? Yes—Here's How to Protect Yourself

This is off-topic from my usual menpause content. I have a friend (ages 79) who has recently had some cases of skin cancer on her hands and arms. Her Dr. said it could be from the UV rays while driving. I did some research and here's what I found:

Most of us don’t think twice about the time we spend in the car. Whether it’s running errands, commuting to work, or going on road trips, driving is part of daily life. But did you know your car could be exposing you to harmful UV rays—even when the windows are closed?

This hidden risk has become a serious issue, especially for older adults. In fact, dermatologists are seeing more cases of skin cancer—especially on the left side of the body, like the face, hands, and arms—directly linked to long-term sun exposure while driving.

☀️ How UV Rays Penetrate Car Windows

Here’s what you need to know:

• Front windshields are typically treated to block most UVA and UVB rays.

• Side and rear windows, however, often do not have the same level of UV protection.

• UVA rays, which penetrate deeper into the skin, can pass through untreated glass and cause premature aging, sunspots, and skin cancer over time.

This is especially concerning for frequent drivers or older adults who have accumulated years of driving exposure—just like your friend.

🚗 Why the Left Side Is at Higher Risk

In countries where the driver’s seat is on the left, the left arm, hand, and side of the face receive significantly more sun exposure. That’s why doctors often notice a pattern of skin damage or cancer on that side first.

🛡️ How to Protect Yourself While Driving

Thankfully, there are simple and effective steps you can take to lower your risk:

1. Use a Broad-Spectrum Sunscreen

Apply SPF 30 or higher on your face, neck, arms, and hands—even on cloudy days or quick trips. Look for a sunscreen labeled “broad-spectrum” and reapply every 2 hours if you’re driving long distances.

2. Wear Protective Clothing

Lightweight, long-sleeved shirts, UV-protective gloves, and wide-brimmed hats can block direct sunlight from reaching your skin while driving.

3. Install UV-Blocking Window Film

Consider adding clear UV-filtering film to your car windows. These are transparent, affordable, and block up to 99% of UVA and UVB rays without darkening your windows.

4. Drive During Low Sun Hours

Whenever possible, avoid driving during peak sunlight hours (10 a.m. to 4 p.m.). Early morning or late afternoon driving minimizes UV exposure.

5. Use Sun Shades

Use removable sun shades on side windows, especially if you're parked or waiting in your vehicle. They can dramatically reduce UV penetration and heat.

Final Thoughts

Your car may feel like a safe, enclosed space—but sunlight doesn’t care about the glass barrier. Long-term UV exposure while driving is real and can lead to skin damage or cancer, especially on vulnerable areas like the hands and arms.

The good news? With a few mindful habits and inexpensive upgrades, you can drastically cut down your risk.
