Can Ultra Violet Penetrate Through Clothing

Can UV Rays Go Through ClothingEveryone knows that UV rays are harmful and dangerous for the skin. It is obvious that when at the beach or pool the skin is exposed to UV radiation. But can UV rays go through clothing too? Are we protected in the sun when wearing regular clothes?

Can a T shirt block UV radiation? In this article we will try and answer some of these questions, and offer solutions for those who understand the threat.

UVA Can Penetrate Most Fabrics

What we call “UV” scientists divide into three groups – UVA, UVB and UVC.

UVC are deadly UV rays which the sun sends and luckily for us do not reach earth. UVB are short rays which do reach the surface of earth, they cause tanning and cancer, but their intensity varies throughout the seasons.

UVA are the longest of the three types of Ultra Violet rays. Their wavelength is very close to visible light. UVA can penetrate most fabrics.

In fact wearing a cotton T shirt will reduce approx 5% of UV, while 95% will reach the skin. UVA can penetrate clouds, glass, plastic and will reflect of surfaces around us, like snow, water, sands, windows, windshields and more.

Ultra Violet Protection Factor For Clothes

Except for arms and face, most of our body is covered by clothes. In order to be protected from UV radiation most people would apply SPF creams. But these cover only the exposed skin… what happens to the rest of the body? It gets loads of UV which reaches underneath the clothes, especially UVA radiation. Is it dangerous? Yes. Is it reversible? No. What ever the skin absorbs at the cells.

The solution?

 UPF clothings. Like SPF is the rating for creams sun protection level, there are ratings for fabrics too. In recent years UV blocking fabrics became more effective and their price deceased as the size of the market grew.

UPF clothing pass unique lab tests, checking how much of the UV is blocked by the fabric. The highest level possible gets the 50+ UPF rating. This means that less than 1/50 of the UV managed to penetrate the fabric. It’s translated to at least 98% blockages of incoming UV.

Wearing UPF clothes, means being UV protected even when out in the sun. UPF fabrics use tight weave, advanced dyes, their manufacturers added UV blocking ingredients to the dye and threads, using technological patents to keep nearly all UV away.

Here are examples for high rated UPF clothings! Unlike regular clothing, these will block and/or reflect 98% of the UV from reaching the skin.
