Why do we get Hiccups?
Everybody gets hiccups (also sometimes spelt ‘hiccoughs’). Even when babies are still in the womb they hiccup, which can feel very odd to their mother! But why do we get them and how can you stop them?
What are Hiccups?
Hiccups are caused by the diaphragm (pronounced DYE-uh-fram). This is a large, dome-shaped muscle that sits at the bottom of your chest cavity, below your lungs. When we breathe in the diaphragm tightens, helping to pull air into the lungs, and when it relaxes it forces the air back out again. Sometimes the diaphragm becomes irritated and instead of tightening smoothly it does it in a jerky way, which makes air suddenly rush into your throat. This air is stopped when it hits the voice box and makes the opening between the vocal cords close very suddenly. This is what produces the sound of the hiccup.
