Avoid damaging sunburns this summer by using sunscreen properly, covering up when possible, and playing outside during recommended times, according to Kids Health. Even if your children don’t seem to burn easily, damaging UVA and UVB rays from the sun will still take their toll. Sunscreen with an SPF rating of 30 or higher should be applied generously and frequently re-applied. Better than sunscreen, cover up the body with hats, long sleeves, umbrellas, and other accessories that will block the sun’s rays completely. In all cases, try not to stay outside between 10 a.m. and 4 p.m. when the angle of the sun is at its strongest and most direct.
