Getting the hiccups can be a truly unpleasant experience, particularly if they do not go away quickly. Most people have experienced this unpleasant sensation at some point in their lives and, while they often go away on their own, they can last for a surprisingly long time. And, despite how common they are, scientists remain as in the dark about what causes them and what they do (to say nothing of how to cure them), as they have always been.
Of course, science has come up with a number of theories as to why humans hiccup. Some suggest it’s a holdover from an earlier stage of evolution, while others think it might have to do with the need for baby animals to get rid of excess gas. As of yet, there have been surprisingly few systematic studies on the mechanics and causes of hiccups, let alone how to get rid of them.
