Factors That Diminish UV Protection
Even with a high UPF rating, the effectiveness of clothing in shielding against harmful UV rays can be compromised by certain factors. For instance, when garments get wet or stretched, their ability to provide adequate protection diminishes. The stretching of fabric leads to an increase in the distance between fibers, which allows more light to penetrate through the clothes and reach the skin. As a result, loose-fitting clothes tend to offer better UV protection compared to tight-fitting ones.
Is Sunscreen Still Necessary?
While sun-protective clothing can provide a certain level of protection to the areas it covers, it is important to remember that the rest of your body still needs to be shielded from harmful UV rays. This is where sunscreen, along with hats and sunglasses, comes into play. To ensure maximum protection, it is recommended to apply sunscreen not only on exposed skin but also starting from an inch below the ends of your sleeves and pant legs.
