Applying sunscreen is important, but you don’t always have it on hand. How harmful is it to sit down on a terrace at the end of the day without having applied sunscreen?
Actually, you should always apply sunscreen, especially when the sun is shining. The UV index is more important than the time of day, although it is often highest between 12:00 PM and 3:00 PM. “The higher the UV index, the greater the consequences for our health,” says Cynthia van Amerongen of The Skin Cancer Foundation.
UV index is independent of the temperature. The higher the sun is in the sky, the less cloud cover and the cleaner the air: the higher the UV index.
Van Amerongen advises you to protect yourself well from UV index 3. “There are several apps where you can find the UV index of the day.”
