Don’t Let Driving Age Your Skin: Defending Your Skin Against UV Rays While Driving

Have you ever noticed the stark contrast in aging between the left and right side of a truck driver’s face? It’s a dramatic example of the impact of UV exposure. Today, we’re going to delve into the topic of UV rays inside your car and why it’s important to protect your skin even when you’re behind the wheel.

UV Rays and Skin Damage:

UV rays come in two forms: UVA and UVB, both of which can be harmful to your skin. Many people assume that being inside their vehicle shields them from these damaging rays. However, even with the windows up, your skin remains vulnerable to sun damage. Both basal cell carcinomas and melanomas are associated with intermittent exposure to UV rays, whereas squamous cell carcinomas are associated with chronic (or “long term”) exposure

Different Types of Glass:

Let’s take a closer look at the glass used in vehicles. There are two common types: tempered glass and laminated glass. Tempered glass is strengthened through a process of heating and rapid cooling, causing it to break into tiny pieces when shattered. It is primarily used for side windows.

On the other hand, laminated glass consists of a layer of polyvinyl butyral (PVB) sandwiched between two or more layers of glass. This type of glass is used for windshields due to safety regulations. Laminated glass offers decreased UV transmission and is safer in the event of shattering.

UV Protection of Window Glass:

Both tempered and laminated glass block UVB radiation effectively. However, the level of UVA protection differs. Windshields, made of laminated glass, block the majority of UVA radiation. In contrast, side and back windows, typically composed of tempered glass, only block around 21% of UVA radiation.

The Role of Window Films:

Research studies have confirmed that applying window films to tempered glass significantly reduces the transmission of UV rays. In fact, such films can result in up to a 99% reduction in UV ray transmission.

Take-Home Points:

To ensure your skin is protected from UV radiation while driving, remember these key points:

  1. UV rays can still reach your skin inside the car, so take precautions.
  2. Tempered glass in side windows does not provide sufficient protection against UVA rays.
  3. Apply high-quality sunscreen before getting behind the wheel.

Conclusion:

Don’t underestimate the potential harm of UV rays while driving. Even though you may be enclosed in your vehicle, your skin remains vulnerable to UVA and UVB radiation. Take steps to protect yourself by wearing sunscreen and considering the use of window films for added UV protection. Stay safe and keep your skin healthy during your time on the road.
