(Men's Health) Sense-sharpening brain implants are decades away. Until then, use these simple tricks:
Look at the body part that's doing the touching. A British study found that looking at the body part increase activity in the area of the brain that controls sensation. The reserve works, too. Look away when receiving a shot.
Simply smile. The muscles that turn your frown upside down also tense your middle-ear muscles. In turn, this softens low-frequency noises including the hum of an air conditioner, the din of traffic, or office chatter, by as much as 20 decibels.
Take a good whiff of your food before you eat. "Ninety% of taste is smell," says Alan Hirsch, M.D., a neurologist. "The more odor molecules hit receptors in your nose, the more robust your sense of taste."
Run the hot water. Before odors reach your smell receptors, they first pass through a membrane. Warm, moist air helps odors dissolve into the membrane. But hurry, your heightened sense will last only a few minutes.
Position your computer monitor so you're looking slightly down at it. Your eyes won't be open as wide, so they won't be exposed to as much cornea-drying air. That means less eye strain and blurring and better vision.
