Whether uncomfortable, embarrassing or just plain weird,

there are some pretty funky things that our bodies do.

Curious about the causes of such reactions as hiccups,

goose bumps and eye twitches, we spoke with Eric Plasker,

DC, author of The 100 Year Lifestyle, to get the real scoop.

Read on to discover the common

reasons for 14 peculiar bodily functions .

Yawns

If your body is low on oxygen, your mouth opens wide and

tries to suck more in. Yawning is a way to regulate the amount

of carbon dioxide and oxygen in your blood. Unfortunately,

yawns are nearly impossible to stifle.

Eye Twitches

Serious eye twitches can be a symptom of neurological disorders,

but often there is a more mundane explanation. Common causes

for eye twitches include stress, lack of sleep extended staring

or eye strain. Before you get frantic, try reducing your stress level,

cutting back on caffeine and catching up on sleep.

Itches

According to Dr. Plasker, our skin most often gets itchy because of

dryness associated with the environment or over-washingâ€"

water and soap can strip skin of its natural oils, thus sapping

moisture. Face or body lotion should be able to keep these types

of itches under control; also look for body washes and soaps

labeled â€œmoisturizing. If you still have itchy patches,

you may be experiencing an allergic reaction to a chemical,

plant, food, animal or drug.

See an allergist if the itching is persistent.

Hiccups

If youâ€™ve frequently got a case of the hiccups, try slowing

down when you eat and drink, suggests Dr. Plasker. Doing

either too quickly causes your stomach to swell; this irritates

your diaphragm, which contracts and causes hiccups.

You may also get hiccups in emotional situations or if

your body experiences a sudden temperature change.

In both of these cases, the hiccups are a result of a glitch in

your nerve pathways, which is why a sudden scareâ€"which

might shake up and reset your nervesâ€"can

sometimes end an episode.

Goose Bumps

Those tiny bumps that cover your skin when youâ€™re cold or

scared are actually a defense mechanism. Goose bumps occur

when the arrector pili, a tiny muscle that connects the hair follicle

with skin, contracts and makes the hair stand on end. If you

had more hairâ€"like cavemen didâ€"the upright hair would

trap air to keep you warm or make you look bushier and

therefore more threatening to predators

Sneezes

Sneezes happen when your body is trying to expel an irritant

from the nasal cavity. If you have allergies, pollen or pet dander

is usually to blame. If you have a cold, your body makes mucus to

trap the virus, and sneezing helps force it (and the sickness) out

of your body. An over-the-counter allergy or cold medicine helps

suppress your reaction to allergens or reduce mucus production,

which should prevent sneezing fits.

Cough

A cough is another mechanism your body uses to get rid of irritants.

There are special cells along your air passage, says Dr. Plasker,

that recognize irritants and force them out. Common colds,

sinus infections and pneumonia all increase your bodyâ€™s

mucus production, which triggers coughing. Smoking and asthma

also tend to irritate the cells. To help cut down on chronic

coughing, exercise regularly and practice good posture to

keep your air passage open.

Charley Horses

These sudden, super-painful muscle spasms can be blamed on

several things, including dehydration or electrolyte imbalancesâ€"

often from strenuous exercise. After a demanding workout or an

extra-long run, sip a sports drink to keep your system running

smoothly. If you experience this type of cramping,

walk around to help relieve the pain.

Shivers

Shivering, says Dr. Plasker, is full-body muscle twitching.

When your temperature drops too low, your body shakes all

over in an attempt to generate heat. The only way to cure these

kind of shivers is to get your temperature back to 98.6°F.

Ear Ringing

Ear ringing, or tinnitus, can happen for two reasons. If you have

fluid or an infection in your middle ear, you may hear a constant

buzz. However, the more common cause is damage to the

microscopic ends of your hearing nerves, which often happens

when youâ€™re exposed to loud noises. To prevent permanent

damage (and preserve your hearing), wear earplugs at

concerts and sporting eventsâ€"or even

when you mow the lawn.

Stomach Rumbles

As food, liquid and gas move through your digestive tract, your

stomach muscles and intestines contract and cause rumbling

noisesâ€"borborygmi is the scientific name. Everyoneâ€™s stomach

makes noise during digestion, but if you have extra-loud

rumbles, a teaspoon of olive oil or a cup of herbal tea with

lemon may help ease them, says Dr. Plasker.

Limbs Falling Asleep

When thereâ€™s consistent pressure on part of a limbâ€"like

when you sit on your feet or rest your head on an armâ€"the

pressure squeezes your nerve pathways and scrambles messages

sent to your brain. The mixed messages make you lose feeling

in the squished body part because your brain has trouble telling

it what to do. To prevent a case of pins and needles, avoid

sitting or lying in positions that compress your nerves.

Seeing Stars

If you stand too quickly, suffer a blow to the head or are

stricken by a migraine, thereâ€™s a good chance youâ€™ll

see stars as blood surges to different parts of your body.

Generally these tiny flashes of light will fade in a few seconds.

If you see stars for more than a few moments, you could have

a tear or tiny clot in your retina, and you should consult

a physician immediately.

Ear Popping

The Eustachian tube in your inner ear is responsible for

maintaining equal pressure on both sides of your eardrum.

When you experience a rapid change in altitudeâ€"during

takeoff in an airplane or when riding an elevator in an extra-tall

buildingâ€"the Eustachian tube opens to release pressure,

and you hear a pop. To force the tube open

(and â€œpop your ears),

squeeze your nostrils closed while exhaling forcefully

through your nose.
