Hiccups are incredibly irritating and they don't seem to serve ANY purpose. So why do we get them?
Scientists at University College London just finished up a study . . . and they may've FINALLY figured out why we get hiccups.
They found that when newborn babies get the hiccups, it triggers a huge wave of brain signals . . . and they teach the babies' brains about how to regulate breathing.
And as we grow up, the hiccups stick with us, even though they don't serve a purpose anymore. The researchers say they're a, quote, "hangover from early periods of our life that persists into later life."
