"Body Oddity"

Have you ever wondered why your eye suddenly starts twitching uncontrollably or why you sometimes start sneezing and can't stop? Here are the answers to a few “body oddity” questions.

First, it’s not sneezing, it’s “sternutation” and experts say it’s designed to remove irritants from your nose. Basically, dust particles lodged in your nose trigger the production of histamine – which causes your brain to produce a sneeze. Your brain won’t give up until it thinks the invader has been blown out.

What about that eye twitch? It’s usually a spontaneous spasm of muscles caused by fatigue, stress, or too much caffeine. Twitches can last from a few seconds to a few hours. The fix: Relax, get some rest, and put down the cappuccino!

Hiccups. They’re caused by a contraction in your diaphragm, which causes your lungs to inhale suddenly, and sets off a chain reaction of hiccups. Your airway opens and closes quickly, halting the flow of air and snapping your vocal cords shut, creating the characteristic “hic.” That’s why holding your breath or drinking a glass of water can break the chain of events.

What causes “brain freeze?” That killer headache you get from eating ice cream. Basically, the roof of your mouth gets too cold, so your body sends a burst of warming blood toward your mouth, and the nerves transmit that as pain. The fix: Press your tongue against the roof of your mouth to heat the area up fast.
