Self-tanners: Are they safe?
Sunless tanning products, also called self-tanners, can give your skin a tanned look without exposing you to harmful ultraviolet (UV) rays. The active ingredient in most sunless tanners is the color additive dihydroxyacetone (DHA). DHA reacts with dead cells in the skin's surface layer to temporarily darken your skin. The coloring gradually fades within a few days. Caution: Most self-tanners don't contain sunscreen. If you spend time outdoors, sunscreen is essential.
Bad breath? Drink more water
If your morning breath seems to last all day, you may not be drinking enough water. Keeping your mouth moist helps wash away food particles and bacteria, which helps keep bad breath at bay. Chewing gum (preferably sugarless) or sucking on candy (again, sugarless) can help, too. If you have chronic dry mouth, your dentist or doctor may recommend an artificial saliva preparation or an oral medication that stimulates the flow of saliva.
Shopping for shades?
Ultraviolet (UV) radiation from the sun can damage your eyes, not just your skin. Choose sunglasses that block 99% to 100% of both UVA and UVB rays. Opt for wraparound sunglasses or closefitting sunglasses with wide lenses that protect your eyes from every angle. Keep in mind that the color of the lenses and the degree of darkness the sunglasses provide have nothing to do with the sunglasses' ability to block UV rays.
Skip booze for better sleep
Alcohol depresses the central nervous system and acts as a sedative. It may help you fall asleep, but it prevents deeper stages of sleep and often causes you to wake up in the middle of the night. If you have trouble falling or staying asleep, say no thanks to the after-dinner drinks.

Applying sunscreen? Don't be stingy
Most people use sunscreen too sparingly. If you use sunscreen generously and frequently, a bottle of sunscreen shouldn't last long. Generally, a liberal application is 1 ounce (30 milliliters) — the amount in a shot glass — to cover exposed parts of the body. You might need to apply more, depending on your body size. If you have a 4-ounce (118-milliliter) bottle, you'll use about one-fourth of it during one application.
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.
Have brown or Black skin? Use sunscreen
If you have brown or Black skin, you still need sunscreen. It's a myth that people with skin that doesn't burn easily can skip the sunscreen. Regardless of skin color, the sun's energy penetrates deeply into the skin. This causes damage that may ultimately lead to skin cancer. If you spend time outdoors during daylight hours, you need to use sunscreen.
