7. Cure your toothache without opening your mouth!

Just rub ice on the back of your hand, on the V-shaped webbed area between your thumb and index finger. A Canadian study found that this technique reduces toothache pain by as much as 50 percent compared with using no ice. The nerve pathways at the base of that V stimulate an area of the brain that blocks pain signals from the face and hands.

9. Stop the world from spinning!

One too many drinks left you dizzy? Put your hand on something stable. The part of your ear responsible for balance -- the cupula -- floats in a fluid of the same density as blood. "As alcohol dilutes blood in the cupula, the cupula becomes less dense and rises," says Dr. Schaffer. This confuses your brain. The tactile input from a stable object gives the brain a second opinion, and you feel more in balance. Because the nerves in the hand are so sensitive, this works better than the conventional foot-on-the-floor wisdom.
