Sitting in the shiny, warm sunlight peeking through the window is quite common. People often think that prolonged exposure to sunlight can give a perfect glowing tan.

But if you want to get the maximum sunlight to get tan then, you should follow an active and outdoor lifestyle.

People often wonder if is it possible to get tan through a window. In this article, we will let you know how long it takes to tan through an open window.

Can Window Glass Provide Sun Protection?

All the window glasses are not the same so, the degree of protection from harmful UVA rays depends on the type of glass and how many rays are passing through them.

Excessive exposure to hazardous rays can cause wrinkles, skin cancer, and skin aging.

A double-glazed window glass will not let the harmful UVA and UVB rays penetrate inside as it acts like an ozone layer. So you do not get tan sitting beside the double-glazed windows.

Ordinary glass can protect your office and house from UVA and UVB rays for some time. But it cannot provide sun protection for a longer period of time.

10 Best Tanning Lotions Without Bronzer

Here I will share with you my personal opinion on some best indoor tanning lotions without bronzer.

How Do Windows Prevent Tanning?

As mentioned earlier the double-glazed glass will only allow some UVA and UVB light in very small quantities. So, it is not very harmful to your skin.


But ordinary glass can let in ultraviolet rays in a larger quantity which can burn that part of your body that is exposed to the window glass.

Is It Possible to Absorb Vitamin D Through Windows?

Besides tanning the UVA rays also promote the production of vitamin D which is necessary for bone growth.

But sitting beside a window cannot help you to get enough vitamin D as most glass windows block this frequency.

So, if you want to get enough sunlight from the ultraviolet rays then, going out in the sun is the best option.

In summer dark-skinned people will take 20 minutes to absorb the proper amount of vitamin D and a fair person will take only 5 minutes to do the same.

Exposure to the sun depends on which part of the world you are in, your skin type, and the time of the year.

Can You Tan Through a Window and How Long Does It Take?

The overall health of your body is reflected in your skin. So, you need to apply sunscreen even if you are tanning yourself by spending time behind the window glasses.

Though it is possible to get tan through an open window, you can get an uneven tan. Tanning your body through window glasses can take a lot of time as well.

But some of the glasses like the double-blazed glass do not allow the ultraviolet rays to penetrate. so, getting tanning through a window sometimes becomes a little tough.

To get a healthy and even tanned look it is better to expose your body completely out in the sun rather than sitting beside a window.

But excessive exposure to sun rays can also harm your skin and you may notice sunburn and reddish patches.
