Sunscreen shopping tips
When you're shopping for sunscreen brand matters less than how you use the product. Look for water-resistant, broad-spectrum coverage with an SPF of at least 30. Check the sunscreen's expiration date. Also, find a sunscreen you like. If you don't care for the sunscreen, you're not as likely to use it consistently.
Sunscreen: One dose doesn't do it
You can't put on sunscreen in the morning and expect to be protected for a full day in the sun. To maximize sun protection, apply generous amounts of sunscreen to dry skin 15 minutes before you go outdoors. Reapply sunscreen every two hours — or more often if you're swimming or sweating.

Time to cut back on caffeine?
That morning cup of coffee or early afternoon soda is probably OK. But more than 400 milligrams of caffeine a day, or more than about four cups of coffee, can cause insomnia, restlessness, headaches and other problems. Start paying attention to how much caffeine you're getting from foods and beverages. Check labels. If you decide to cut back, do it gradually. For example, drink a smaller cup of coffee each day. This will help your body get used to the lower levels of caffeine and lessen potential withdrawal effects.
Time your lotions right
Apply moisturizers immediately after bathing. After washing or bathing, gently pat or blot your skin dry with a towel so that some moisture remains on the skin. Immediately moisturize your skin with an oil or cream to help trap water in the surface cells.
