Hiccups May Be Necessary for Newborn Brain Development, Study Finds

Everyone’s familiar with pesky hiccups. They come on spontaneously, but can be tricky to get rid of - and scientists still aren’t sure why we get them. Now, according to a new study, hiccups may actually help brain development amongst newborns.

The study was conducted by researchers at the University College of London and published in the journal Clinical Neurophysiology. It looked at the brain scans of 13 newborns, born at a range of 30 weeks to 42 weeks. They recorded the infants’ brain activity with electrodes that were placed on their scalps. They also placed movement sensors on the infants’ stomachs to help indicate when the hiccups were occurring.

Researchers found that each hiccup triggered three separate brain waves in all the newborns, the last of which they believe helped the newborn link the sound of a hiccup to a contraction of the diaphragm. They also found that preterm infants were more prone to hiccups and spent approximately 15 minutes a day doing it. Overall, the researchers believe that hiccups may help newborns learn how to control their breath at a cognitive level.

“The activity resulting from a hiccup may be helping the baby’s brain to learn how to monitor the breathing muscles so that eventually breathing can be voluntarily controlled by moving the diaphragm up and down,” said Lorenzo Fabrizi, the study’s senior author, in a news release. “When we are born, the circuits which process body sensations are not fully developed, so the establishment of such networks is a crucial developmental milestone for newborns.”

According to the study, hiccups actually begin in the womb, as early as ten weeks before birth. These scientists may have just worked out why we hiccup, but, of course, more research is needed.

The study’s lead author, Kimberly Whitehead, stated in the release, “Our findings have prompted us to wonder whether hiccups in adults, which appear to be mainly a nuisance, may in fact by a vestigial reflex, leftover from infancy when it had an important function.”
