Normal breathing happens in a regular, repeated pattern. Sometimes, though, there’s a different kind of breath, such as a cough, sneeze, or hiccup.
Sneezing
When something irritating gets inside the nose, the brain’s response is to trigger a sneeze to clear the air passages. After a sharp breath, muscles in the chest and abdomen contract to force the air back out, carrying the intruding particles with it.
Snoring
Sometimes, the breaths we take while asleep can be heard – in fact, the sound can be loud enough to wake the sleeper. Snoring is caused by relaxed tissues vibrating as air passes over them.
Hiccups
Hiccups happen when nerves around the diaphragm get irritated, for example by eating quickly. The diaphragm jerks, making the lungs suddenly suck in air. This makes the vocal cords snap shut, making a “hic!” sound.
Coughing
Coughing occurs when the body tries to clear something irritating, such as smoke, from the airways. The vocal cords close, so that no air can get though. Then the lungs push air against the cords so they suddenly open, releasing an explosive breath.
Yawning
A yawn is a deep breath with the mouth wide open, stretching the eardrums and muscles around the throat. Though we often yawn when we’re tired, no one knows exactly what yawning is for. It may help to cool the brain, or help to keep you awake and alert.
