eli5 why do people get carsick/seasick?

Mostly it’s the disconnect between their eyes and inner ear. Your eyes say you’re moving (or not moving) one way and your sense of balance is saying you’re moving in a different way.
One of the things our bodies evolved to do is to recognize the signs of being poisoned and take steps to eliminate the poison from the body. One of those signs are “your senses are screwed up” and one of those responses is “get whatever you just ate out of your stomach NOW.”
Basically, some people’s bodies throw a false positive for being poisoned and they’re trying to remove anything they ingested which might be poisonous, which means nausea and barfing.
