When I think of August, sunburn and hot days come to mind. Along those lines, most of us do not apply sufficient sunscreen nor hydrate enough. Get out and be active while you are enjoying summer---but protect your body inside and out!
From the American Academy of Dermatology:
Q: When should sunscreen be used?
A: Sunscreen should be applied every day to exposed skin, and not just if you are going to be in the sun. UVB rays cannot penetrate glass windows, but UVA rays can, leaving you prone to these damaging effects if unprotected.
For days when you are going to be indoors, apply sunscreen on the areas not covered by clothing, such as the face and hands. Sunscreens can be applied under makeup, or alternatively, there are many cosmetic products available that contain sunscreens for daily use. Sun protection is the principal means of preventing premature aging and skin cancer. It's never too late to protect yourself from the sun and minimize your future risk of skin cancer.
Don't reserve the use of sunscreen only for sunny days. Even on a cloudy day, up to 80 percent of the sun's ultraviolet rays can pass through the clouds. In addition, sand reflects 25 percent of the sun's rays and snow reflects 80 percent of the sun's rays.
Q: How much sunscreen should be used, and how often should it be applied?
A: Sunscreens should be applied to dry skin 15 to 30 minutes BEFORE going outdoors. When using sunscreen, be sure to apply it to all exposed areas and pay particular attention to the face, ears, hands, and arms. Coat the skin liberally and rub it in thoroughly — most people apply only 25 to 50 percent of the recommended amount of sunscreen.7 One ounce, enough to fill a shot glass, is considered the amount needed to cover the exposed areas of the body properly. Don't forget that lips get sunburned, too, so apply a lip balm that contains sunscreen with an SPF of 30 or higher.
Sunscreens should be reapplied approximately every two hours or after swimming or perspiring heavily. Even so-called "water-resistant" sunscreens may lose their effectiveness after 40 minutes in the water. Sunscreens rub off as well as wash off, so if you've towel-dried, reapply sunscreen for continued protection.
Also, there are a number of combination cosmetic products, such as moisturizers that contain sunscreen, but it is important to remember that these products also need to be reapplied to achieve continued UV protection.
