Why do we hiccup?
Diaphragm's Tantrum
Why do we hiccup?

You're sitting there, minding your own business, when suddenly — hic — your body does something completely ridiculous. Your chest jumps. A weird squeaky sound comes out. You didn't ask for this. So what's going on?
The culprit is a dome-shaped muscle called your diaphragm, sitting right under your lungs like a trampoline under a bouncy castle. When you breathe normally, it pulls down smoothly to let air in, then relaxes to push air out. Steady, calm, professional.
