For some lucky folks, reading in the car is a go-to road-trip activity. For others, just the thought of picking up a book while riding shotgun sends them running for the bathroom.
This TED-Ed animation narrated by Rose Eveleth attempts to explain why about one-third of the population falls into the unlucky category of people who suffer from motion sickness.
Eveleth makes it clear that doctors and scientists don't know the exact reason for motion sickness. But the theories behind this queasiness offer some neat insight into the goings-on inside our bodies when we experience motion-induced nausea.
Scientists don't know when the day will come that they pinpoint a cure-all for motion sickness. Until then, unfortunately, get used to napping in the backseat all the way home.
