18 Health Tricks to Teach Your Body

Eating 10 hot dogs in 6 minutes and belching the national anthem may impress your friends, but neither of those feats will do much for your body—at least not much good.

Instead, why not train yourself to do something that may actually pay off?

We're not talking bench presses and interval training (though those do help). You can teach your body to cure itself from everyday health ailments—side stitches, first-date jitters, even hands that have fallen asleep.

Just study this list, and the next time your friends challenge you to an ice cream eating contest, chow down: You know how to thaw a brain freeze—and 17 other tricks that'll make everyone think you're the next David Blaine. But without all that "hold your breath for 17 minutes" mess.

Cure a Tickling Throat

When you were 9, playing your armpit was a cool trick. Now, as an adult, you can still appreciate a good body-based feat, especially if it serves as a health remedy. Take that tickle in your throat: It's not worth gagging over. Here's a better way to scratch your itch: Scratch your ear. "When the nerves in the ear are stimulated, it creates a reflex in the throat that can cause a muscle spasm," says Scott Schaffer, M.D., president of an ear, nose, and throat specialty center in Gibbsboro, New Jersey. "This spasm relieves the tickle."

Experience Supersonic Hearing

If you're stuck chatting up a mumbler at a cocktail party, lean in with your right ear. It's better than your left at following the rapid rhythms of speech, according to researchers at the UCLA David Geffen School of Medicine. If, on the other hand, you're trying to identify that song playing softly in the elevator, turn your left ear toward the sound. The left ear is better at picking up music tones.

Overcome Your Most Primal Urge

Need to pee? No bathroom nearby? Fantasize about Jessica Simpson. Thinking about sex preoccupies your brain, so you won't feel as much discomfort, says Larry Lipshultz, M.D., chief of male reproductive medicine at the Baylor College of Medicine. For best results, try Simpson's "These Boots Are Made for Walking" video.

Feel No Pain

German researchers have discovered that coughing during an injection can lessen the pain of the needle stick. According to Taras Usichenko, author of a study on the phenomenon, the trick causes a sudden, temporary rise in pressure in the chest and spinal canal, inhibiting the pain-conducting structures of the spinal cord.

Clear Your Stuffed Nose

Forget Sudafed. Here's an easier, quicker, and cheaper remedy to relieve sinus pressure: Alternate thrusting your tongue against the roof of your mouth, then pressing between your eyebrows with one finger. This causes the vomer bone, which runs through the nasal passages to the mouth, to rock back and forth, says Lisa DeStefano, D.O., an assistant professor at the Michigan State University college of osteopathic medicine. The motion loosens congestion; after 20 seconds, you'll feel your sinuses start to drain.

Fight Fire Without Water

Worried those wings will repeat on you tonight? Try this preventive remedy: "Sleep on your left side," says Anthony A. Starpoli, M.D., a New York City gastroenterologist and assistant professor of medicine at New York Medical College. Studies have shown that patients who sleep on their left sides are less likely to suffer from acid reflux. The esophagus and stomach connect at an angle. When you sleep on your right, the stomach is higher than the esophagus, allowing food and stomach acid to slide up your throat. When you're on your left, the stomach is lower than the esophagus, so gravity's in your favor.

Cure Your Toothache

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.

Make Burns Disappear

When you accidentally singe your finger on the stove, clean the skin and apply light pressure with the finger pads of your unmarred hand. Ice will relieve your pain more quickly, Dr. DeStefano says, but since the natual method brings the burned skin back to a normal temperature, the skin is less likely to blister.

Stop the World from Spinning

One too many drinks left you dizzy? Ah, luckily there's a remedy. 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.

Unstitch Your Side

If you're like most people, when you run, you exhale as your right foot hits the ground. This puts downward pressure on your liver (which lives on your right side), which then tugs at the diaphragm and creates a side stitch, according to The Doctors Book of Home Remedies for Men. The fix: Exhale as your left foot strikes the ground.

Stanch Blood with One Finger

Pinching your nose and leaning back is a great way to stop a nosebleed—if you don't mind choking on your own O positive. A more civil approach: Put some cotton on your upper gums—just behind that small dent below your nose—and press against it, hard. "Most bleeds come from the front of the septum, the cartilage wall that divides the nose," says Peter Desmarais, M.D., an ear, nose, and throat specialist at Entabeni Hospital, in Durban, South Africa. "Pressing here helps stop them."

Make Your Heart Stand Still

Trying to quell first-date jitters? Blow on your thumb. The vagus nerve, which governs heart rate, can be controlled through breathing, says Ben Abo, an emergency medical-services specialist at the University of Pittsburgh. It'll get your heart rate back to normal.

Thaw Your Brain

Too much Chipwich too fast will freeze the brains of lesser men. As for you, press your tongue flat against the roof of your mouth, covering as much as you can. "Since the nerves in the roof of your mouth get extremely cold, your body thinks your brain is freezing, too," says Abo. "In compensating, it overheats, causing an ice-cream headache." The more pressure you apply to the roof of your mouth, the faster your headache will subside.

Prevent Near-Sightedness

Poor distance vision is rarely caused by genetics, says Anne Barber, O.D., an optometrist in Tacoma, Washington. "It's usually caused by near-point stress." In other words, staring at your computer screen for too long. So flex your way to 20/20 vision. Every few hours during the day, close your eyes, tense your body, take a deep breath, and, after a few seconds, release your breath and muscles at the same time. Tightening and releasing muscles such as the biceps and glutes can trick involuntary muscles—like the eyes—into relaxing as well.

Wake the Dead

If your hand falls asleep while you're driving or sitting in an odd position, rock your head from side to side. It'll painlessly banish your pins and needles in less than a minute, says Dr. DeStefano. A tingly hand or arm is often the result of compression in the bundle of nerves in your neck; loosening your neck muscles releases the pressure. Compressed nerves lower in the body govern the feet, so don't let your sleeping dogs lie. Stand up and walk around.

Impress Your Friends

Next time you're at a party, try this trick: Have a person hold one arm straight out to the side, palm down, and instruct him to maintain this position. Then place two fingers on his wrist and push down. He'll resist. Now have him put one foot on a surface that's a half inch higher (a few magazines) and repeat. This time his arm will cave like the French. By misaligning his hips, you've offset his spine, says Rachel Cosgrove, C.S.C.S., co-owner of Results Fitness, in Santa Clarita, California. Your brain senses that the spine is vulnerable, so it shuts down the body's ability to resist.

Breathe Underwater

If you're dying to retrieve that quarter from the bottom of the pool, take several short breaths first—essentially, hyperventilate. When you're underwater, it's not a lack of oxygen that makes you desperate for a breath; it's the buildup of carbon dioxide, which makes your blood acidic, which signals your brain that somethin' ain't right. "When you hyperventilate, the influx of oxygen lowers blood acidity," says Jonathan Armbruster, Ph.D., an associate professor of biology at Auburn University. "This tricks your brain into thinking it has more oxygen." It'll buy you up to 10 seconds.

Read Minds

Your own! "If you're giving a speech the next day, review it before falling asleep," says Candi Heimgartner, an instructor of biological sciences at the University of Idaho. Since most memory consolidation happens during sleep, anything you read right before bed is more likely to be encoded as long-term memory.

8 Home Remedies That Actually Work for Diseases

Duct Tape to Remove Warts

In 2002, a group of doctors compared duct tape’s effectiveness with liquid nitrogen in removing warts. After two months of wearing duct tape on a daily basis and using a pumice stone about once a week to exfoliate the dead skin, 85 percent of patients' warts were gone, whereas freezing only removed 60 percent. “The question is whether there is something in the chemical adhesive itself, or if the occlusion (suffocation) causes the destruction of the wart,” says New York City–based dermatologist, Robin Blum, MD. “The other thinking is that the duct tape causes irritation, which stimulates our body’s immune cells to attack the wart.”

Vapor Rub to Cure Nail Fungus

While there are no studies to prove coating infected toenails with vapor rub once or twice a day is an effective treatment for nail fungus, a basic Internet search results in a number of personal testaments to the medicinal ointment's fungus-killing powers. “I’ve heard many patients say that vapor rub does help, but I’m not exactly sure why,” Dr. Blum admits. While some argue it's the menthol in the balm that kills the fungus and others say it’s the smothering effect of the thick gel, if used consistently, vapor rub has been shown to get rid of not just the fungus, but the infected toenail, too, which will turn black and eventually fall off. When the new nail grows in, it should be fungus-free.

Oatmeal to Soothe Eczema

“This is absolutely true, as oats have anti-inflammatory properties,” Dr. Blum says. Whether it’s used as a paste or poured into a bath, most experts recommend choosing colloidal (finely ground) oatmeal and soaking the affected area for at least 15 minutes. In addition to reducing inflammation, oats are thought to have an antihistamine effect, Dr. Blum says. By lowering levels of histamine, which triggers inflammation as part of the immune system’s recovery response, she explains, oats prevent or reduce the redness.

Yogurt to Cure Bad Breath

Bad breath comes from a number of places, the two most common being the mouth and the stomach. The neutralizing powers of yogurt and other probiotics treat the latter cause. “Yogurt shouldn’t have any effect at all on the bacteria that live on the tongue because it’s not there long enough,” says Robert Meltzer, MD, a New York City–based gastroenterologist and attending physician at Lenox Hill Hospital. However, it likely has a neutralizing effect on the acid that resides anywhere between the mouth and the stomach, including the back of the throat and the esophagus, he explains. “I think almost any milk product or food that contains live cultures would have the same effect." While yogurt can get rid of bad breath that results from gastrological conditions, like acid reflux, it won't have any real effect on bad breath that is the product of gum, liver or lung disease, says Ohio-based dentist Matthew Messina, DDS.

A Spoonful of Sugar to Cure Hiccups

In 1971, Edgar Engelman, MD, conducted a study to find out if a spoonful of sugar really is an effective cure for hiccups. He assembled a group of 20 patients who had been experiencing intractable hiccups for more than six hours, eight of whom had had them anywhere from a full day to six weeks. Each of the test subjects was given one teaspoon of white granulated sugar to swallow dry, and for 19 of the 20 hiccup patients, the cure was immediate. André Dubois, MD, a gastroenterologist in Bethesda, Maryland, noted in The Doctors Book of Home Remedies that “the sugar is probably acting in the mouth to modify the nervous impulses that would otherwise tell the muscles in the diaphragm to contract spasmodically."

Bite a Pencil to Cure a Headache

While doctors aren’t sure why we do it, clenching our teeth is a common side effect of stress. According to Fred Sheftell, MD, director of the New England Center for Headache in Stamford, Connecticut, when we clench up, we strain the muscle that connects the jaw to the temples, which can trigger a tension headache. By placing a pencil between our teeth—but not biting down—we relax our jaw muscles, which eradicates tension and reduces pain. Just remember, the remedy really only applies to tension headaches—not migraines or headaches caused by sinus pressure, etc.

Olives for Motion Sickness

According to the National Library of Medicine, there are a number of symptoms that present themselves as a result of motion sickness, including increased salivation, which is the body’s way of protecting the teeth from the high doses of acid accompanied by vomit. Enter olives, which contain tannins that, when released in the mouth, work to dry saliva—first eliminating the symptom and then the body’s instinct to follow suit. However, the treatment is only effective during the early stages of nausea, when the salivation changes first appear. Photo: Thinkstock

Gargle Salt Water for a Sore Throat

When you were a kid and had a sore throat, your mom likely made you gargle warm water with salt in it...and she was definitely on to something. According to Douglas Hoffman MD, PhD, author of the website The Medical Consumer's Advocate, a sore throat is an inflammatory response of the infected tissues, and the salt helps draw out the excess fluid to temporarily decrease swelling and the pain it causes. Most remedies call for a ratio of 1 tablespoon salt to 8 ounces of water, but it's always better to opt for more salt rather than less. Just keep in mind that you are treating the symptoms—not the illness. As Dr. Hoffman notes on his website: “The relief is very real, but also tends to be short-lived, since the gargle has done nothing to remove the cause of the sore throat.”
