Why do we hiccup?

Hiccups occur due to sudden, involuntary contractions of the diaphragm, the muscle that helps us breathe. This forces a quick intake of air, causing the vocal cords to close abruptly, producing the "hic" sound. Common triggers include eating too fast, drinking carbonated beverages, swallowing air, sudden temperature changes, and stress. Most hiccups are harmless and stop within minutes. However, if hiccups last more than 48 hours, they may be linked to nerve irritation, acid reflux, neurological issues, or medication side effects. Simple remedies like holding your breath, drinking water, or swallowing sugar often help. Though common, hiccups remain a reflex with no clear purpose.
