  • There are more than one and a half billion people out there using the internet every

  • day, and just like you, they're looking for answers. We here at SciShow are looking for

  • answers too, answers to questions about science and nature and the human body, Earth and the

  • universe! So we're working with Google and YouTube to answer ten of the most popular

  • questions searched for on the internet. This is the World's Most Asked Questions!

  • [Intro]

  • Today’s question is: How can I get rid of hiccups?

  • People have all kinds of hiccup remedies that they swear by, none of which seem to have

  • much to do with each other -- like, swallowing a teaspoon of sugar, or guzzling a glass of

  • water, or just holding your breath.

  • But to figure out how to get rid of hiccups -- and why we get them in the first place

  • -- you gotta start with getting to know your diaphragm.

  • The diaphragm is a sheet of muscle under your lungs that is one of the most important muscles

  • you have, if you enjoy things like breathing.

  • And a hiccup is just an involuntary spasm of the diaphragm that causes it to contract

  • suddenly.

  • When that happens, you take in a gulp of air really quickly, until your vocal folds -- the

  • membranes at the top of your throat -- clamp shut. That’s what causes thehicsound.

  • Most of the time, the spasm stops as quickly as it started, and you can just sayexcuse

  • meand get on with your life.

  • But sometimes, those spasms won’t stop ... which means it’s time to get your diaphragm to

  • relax.

  • To do this, you basically gotta hit the reset button on your nervous system -- or at least

  • the part that controls your diaphragm.

  • You can do that in a couple of different ways.

  • One is to stimulate your vagus nerve -- that's a nerve that runs down your neck from the

  • base of your brain, and it regulates some of your body’s most important functions,

  • including your heartbeat and your breathing.

  • Basically, you need to stimulate this nerve -- distract it, if you will -- so itll

  • stop constantly zapping your diaphragm.

  • So, some people have luck getting rid of hiccups by swallowing a teaspoon of sugar. Sounds

  • delicious, but it’s harder than it sounds. The act of gulping down those dry granules

  • can provide just enough confusing stimulus for your vagus nerve to start focusing on

  • your throat, and leave your diaphragm alone.

  • Another more common approach to kicking the hiccups is to increase the level of carbon

  • dioxide in your bloodstream. That might seem a little weird, but your natural breathing

  • rhythms are regulated by your CO2 levels, and if they get too high, your nervous system

  • will signal your diaphragm and lungs to make sure theyre doing their job.

  • And this is what’s behind most of the hiccup-busting techniques youve probably heard of -- like

  • holding your breath, or breathing into a paper bag, or drinking a tall glass of water. All

  • of that stuff stops your intake of oxygen and ramps up your internal CO2 concentration,

  • which signals your diaphragm to get its head in the game and fix things.

  • If the human body weren't so weird, it wouldn't be so fascinating.

  • And speaking of hiccup cures, of those of you who filled out our SciShow Survey, 54%

  • said that holding your breath was your preferred method for relieving hiccups, while at a close

  • second was drinking water, at 37%.

  • We're loving answering these questions, but of all the questions in the world, what do

  • YOU most want answered? Let us know on Facebook or Twitter or in the comments down below,

  • and we will answer the best questions in a new video at the end of the month. Don’t

  • forget to use the hashtag #WMAQ, for World's Most Asked Questions, and stay tuned for more

  • answers here on SciShow.
