The Wonderful Reason Babies Hiccup So Much

The video explores the phenomenon of hiccups, which are common and usually harmless. It delves into the physiological mechanism involving the diaphragm and glottis. Hiccups are prevalent in fetuses and newborns, suggesting a developmental role. A study found that baby hiccups might help form neural circuits for sensing internal organs. The purpose of adult hiccups remains unclear, but they may be a leftover reflex from early development.

• At birth

• Nine weeks old

• Twenty-four weeks old

What did the study on newborns reveal about the brain's response to hiccups?
