When it comes to staying safe under the sun, we need to clear up some myths. Many think the sun’s heat is what hurts us. But it’s really the invisible UV rays that cause damage, not the temperature. So, even on a cloudy day, your skin could be at risk because UV rays go through clouds.
And here’s another important fact: UV rays can hurt you every day of the year, not just in the summer. That’s why using sunscreen is key, no matter what the season is. Skipping sunscreen could lead to skin cancer and other harmful skin problems.

An SPF 30 sunscreen, for example, lets just 1/30th of the UVB rays through to the skin. This means it offers 30 times more protection than not using sunscreen.
What is SPF?
SPF measures how effective a sunscreen is at stopping UVB rays from burning the skin. The higher the SPF, the more protection you get from sunburn. A sunscreen with SPF 30 or higher is best. It can block up to 97% of the UVB rays. But remember, SPF doesn’t tell us about UVA protection, which is also important for avoiding skin damage and cancer.
