We already told you about the importance of wearing sunscreen in our first health of the day tip, but we want to re-emphasize the importance of sunscreen by addressing one of the common misconceptions about it which is the higher the SPF the more protection it’s providing. While there is some truth to this, it becomes a myth over SPF 50. Dermatologists recommend SPF 30 which will protect you from 97% of UVB rays. SPF 45 will protect you from 98% of UVB rays, and anything over this SPF is just a gimmick to get you to purchase the more expensive product. Whatever SPF you’re wearing, be sure to reapply it every 2 hours for maximum protection.
