3 Reasons to Wear Sunscreen on Cloudy and Rainy Days
UV rays penetrate cloud cover Up to 80% of UV radiation still reaches your skin on overcast days. Clouds do not block UV.
Rain does not stop UV Water droplets scatter UV rays rather than blocking them. You are still exposed when it is raining.
Visible light is a reliable indicator If there is enough light to see, there is enough UV to damage your skin. Apply sunscreen whenever you are outside during daylight.
