Sugar to cure hiccups
It seems a spoonful of sugar does more than just help the medicine go down. Taking a teaspoon gets rid of hiccups by stimulating the vagus nerve, which makes the body forget to hiccup. The vagus nerve is a cranial nerve that conveys sensory information about the organs to the brain. When it's distracted by something else — like swallowing sugar — it tells the brain that something more important than hiccuping has come up so the diaphragm spasms stop.
