It’s known that sneezing is a reflex to prevent dust or nose hairs or whatever from getting down into the lungs, but why do people and animals sometimes get hiccups? What function does that serve, and what causes them?...
From my understanding, that’s actually what causes mammals to yawn. No idea why it seems ‘contagious’ though, obviously yawning is more of a voluntary reflex. So why is it that if you see someone else yawn, you’re likely to also yawn? 🤷♂️
Do hiccups serve any actual useful biological function?
