Cover your mouth

The next time you get a case of hiccups, try cupping your hands over your nose and mouth, but continue breathing normally. (You can also breathe into a paper bag if you’ve got one handy.) In either case, the extra dose of carbon dioxide should help you get rid of hiccups.

Use your hands to get rid of hiccups

If covering your mouth doesn’t help you get rid of hiccups, try pressing the palm of your hand with the thumb of your other hand – the harder, the better. Alternatively, you can squeeze the ball of your left thumb between the thumb and forefinger of the right. The discomfort is a distraction that affects your nervous system and may get rid of hiccups. (One of the advantages of this home remedy for hiccups? You can do it under the table without anyone staring at you!)
Would you believe the longest case of hiccups lasted for 68 years?
Hold your breath

The next time you’ve got hiccups, take a deep breath and hold it. When there’s a build-up of carbon dioxide in your lungs, your diaphragm relaxes, which should help get rid of hiccups.
