Why do we hiccup?

Charles Osborne began hiccupping on June 13, 1913, and didn't stop for 68 years.

Ali Seifi, a neurologist at UT Health San Antonio, thinks it's something you ate lately.

Spicy food, fizzy cola, or a heavy meal of dry items like pasta or bread might stimulate the diaphragm, Seifi added.

The diaphragm helps us breathe in and out. It twitches or spasms occasionally. But that's just half of it.

“Those spasms transmit a message to the brain, which tells our throat to seal our voice cords,” he explained. 

This rapid closure causes hiccups.
