Would You Rather Have Hiccups Forever or Always Be About To Sneeze?

Read each section, then decide!

HICCUPS FOR LIFE

HICCUP! You suck in a sharp gulp of air. A few moments later, it happens again. HICCUP! Oh no . . . you have the hiccups!

“Hiccups are sudden, involuntary spasms of the diaphragm, the muscle that sits under our lungs and helps us breathe,” explains Dr. Ali Seifi, a physician who treats patients with injuries to the brain and spinal cord at the University of Texas Health in San Antonio. “These spasms cause a quick intake of breath that is suddenly stopped by the closure of the vocal cords.” These bands of muscle in your throat vibrate to produce your voice. When your vocal cords snap shut, it creates a “hiccup” sound.

There are multiple reasons why someone might develop hiccups. “One is that something irritates the diaphragm, like eating spicy food, drinking soda, eating too quickly, or drinking very cold liquids,” says Seifi. Some medical conditions that affect the brain—like stroke or cancer—can also trigger hiccups.

You’re probably familiar with a couple of methods to cure hiccups, like drinking a tall glass of water, getting scared, or holding your breath. “Common remedies for stopping hiccups aren’t just random tricks,” says Seifi. These cures work by activating the nerves that control the diaphragm and other breathing muscles. This distracts the brain, causing the muscles to relax. Most of the time, hiccups go away anywhere from a few minutes to 48 hours after they start—but not always. One man’s hiccups lasted 68 years! Can you imagine having hiccups for the rest of your life?

THE NEED TO SNEEZE

You feel a tickle in your nose. It gets stronger and stronger until, finally . . . AHCHOO! You let out a satisfying sneeze.

“A sneeze is our body’s response to something in our nose that shouldn’t be there,” says Theresa Larkin, an anatomist, or scientist who studies the human body, at the University of Wollongong in Australia. This reflex—or automatic response—is triggered by irritants, like pollen, dust, or germs, entering the nose. Our body reacts by squeezing the diaphragm to take a big breath in. Then muscles in our abdomen contract, forcefully pushing air from our lungs and out through our nose. That expels the pesky particles at speeds of up to 160 kilometers (100 miles) per hour.

In a few seconds, this fast-moving cloud of hot, moist air can travel as far as 7.6 meters (25 feet). It’s full of droplets that could be carrying germs. If another person inhales them, they may become sick. That’s why sneezers should always cover their nose and mouth.

Right before a sneeze, we feel a tingling sensation in our nose. “That feeling of being ‘about to sneeze’ is the brain detecting messages that there is something annoying the inside of your nose,” says Larkin. Sometimes simply rubbing your nose can cause the tickling to stop. This might be because you’ve knocked out the irritant or because pressing on the area blocked the nerves carrying the message to your brain. But what if this didn’t work? How would you feel if that itchy, tickling feeling NEVER went away?
