We know that applying sunscreen during cold or windy weather seems foolish. If you can’t feel the heat on your skin, it’s easy to believe that you can’t burn. But sun damage is caused by ultraviolet radiation (UV), not temperature, and a cold or cloudy day can have UV levels like a warm and sunny day. According to the Skin Cancer Foundation, up to 80% of the sun’s UV radiation reaches the earth on a cloudy day. In addition, research shows that wind can actually cause worse sun damage in some cases.
Many people in the world of skincare recommend applying sunscreen. Windows only filters UVB rays, but UVA rays still enter. Not only that, the blue light emitted from our screens and indoor lighting can also damage the skin. In a 2010 study, researchers showed the amount of blue light we get from the sun on the skin of the lower backs of 20 volunteers. What they found was that the same person’s skin had more pigmentation, redness, and swelling than exposure to the equivalent level of UVA rays.
For this reason, SPF is important in almost any situation.
