We all know that too much sun exposure can lead to sunburn, but what about when you’re indoors? Can you get sunburned through a window? This question might surprise you, but the truth is even more shocking. In this article, we’ll explore how UV rays work, the role windows play in blocking or letting in sunlight, and the potential risks to your skin even when you’re inside.
Can you get sunburned through a window? What Causes Sunburn?
Before we discuss whether or not you can get sunburned through a window, it’s important to understand what actually causes sunburn. Sunburn occurs when your skin is exposed to excessive UV radiation from the sun. Two types of UV rays—UVA and UVB—affect the skin.
- UVA Rays: Deep skin penetration by this radiation might result in long-term damage like wrinkles and aging.
- UVB Rays: These shorter rays cause most sunburns. They directly affect the top layer of the skin, leading to redness, pain, and peeling.
But what role does glass play in this? Does a window protect us from harmful rays?
Can you get sunburned through a window? Can You Get Sunburned Through a Window?
Now to the big question: Can you get sunburned through a window? The answer is both yes and no. It depends on the type of glass and how much sunlight you’re exposed to.
The Science Behind UV Rays and Windows
Most windows block UVB rays, which are the primary cause of sunburn. Standard glass windows, however, are unable to completely prevent UVA rays, which can cause long-term harm by penetrating deeply into your skin. So, while you may not get a traditional sunburn from UVA rays, you are still exposing your skin to risks.
Different Types of Glass
Windows are not made equally. Let’s examine the different kinds of glass and how well they block UV light:
- Standard Glass Windows: Block most UVB rays but let in a large portion of UVA rays. This means you won’t get sunburn, but your skin can still suffer damage over time.
- Tempered or Laminated Glass: These types of glass offer better protection, blocking more of the UVA rays and offering a higher level of UV protection.
- Tinted Windows: These are commonly used in cars and some buildings. They reduce both UVA and UVB rays, offering the best protection from harmful UV rays.
Does Sun Exposure Through Windows Increase Skin Cancer Risk?
While you may not experience a classic sunburn from UVA exposure through a window, the cumulative damage can still contribute to skin cancer. Long-term exposure to UVA rays is linked to melanoma and other skin cancers. So, while you might feel safe sitting by a sunny window, you could still be risking your skin’s health in the long run.
Can you get sunburned through a window? How to Protect Yourself Indoors
Now that you know you can get sunburned through a window or at least damage your skin, what can you do to protect yourself?
Apply Sunscreen Indoors
Yes, you heard that right—sunscreen isn’t just for the beach. If you spend a lot of time sitting near windows, it’s a good idea to wear sunscreen, especially on your face, hands, and arms. Select a sunscreen that provides broad-spectrum protection, meaning it can shield the skin from UVA and UVB radiation.
Use UV-Protective Window Films
Another great way to protect yourself is by installing UV-blocking window film. These films can be applied to standard windows and are highly effective at reducing both UVA and UVB radiation.
Wear Protective Clothing
If applying sunscreen indoors seems like too much effort, wearing light, long-sleeved clothing can offer a layer of protection. UV-blocking clothes are another excellent option, providing a shield from harmful rays even when you’re inside.
Consider Using Curtains or Blinds
If you spend most of your time next to a sunny window, consider drawing the blinds or curtains during the peak UV hours, which are between 10 AM and 4 PM. This simple step can greatly reduce your UV exposure.
Common Myths About Sunburn and Windows
There are plenty of myths surrounding sunburns, especially when it comes to indoor exposure. Let’s debunk a few common misconceptions:
You Can’t Get Sunburned Indoors
As we’ve already discussed, while it’s unlikely you’ll get sunburned in the traditional sense, UVA rays can still penetrate windows and damage your skin. So, even though you may not see the immediate effects, the risk of long-term damage is real.
Cloudy Days Mean No UV Rays
It’s easy to think that clouds block UV rays, but that’s not the case. Up to 80% of UV rays can pass through clouds, meaning you’re still at risk whether you’re outside or sitting by a window on a cloudy day.
Car Windows Offer Full Protection
Car windows are often tinted to provide some UV protection, but many don’t fully block UVA rays. This means you could still be exposed to harmful radiation while driving.
Can You Get Sunburned Through a Window at Work?
Many people wonder if sitting near a sunny window at work can expose them to harmful UV rays. The answer, as you’ve learned, is yes—you can get sunburned through a window, or more accurately, you can suffer skin damage from UVA exposure. If your desk is near a window, consider taking steps to protect yourself. Wear sunscreen or position yourself away from direct sunlight to reduce the risk.

Protect Your Skin Indoors and Out
While you can get sunburned through a window, which is not entirely true in the traditional sense, UVA rays can still penetrate glass and cause long-term skin damage. So, whether you’re driving, sitting at home, or working near a sunny window, it’s critical to take precautions to protect your skin from damaging UV rays.
