Why You Get Carsick — Your Brain Thinks It's Been Poisoned

Why do you get carsick? Your body isn't weak and your stomach isn't broken. Your brain has looked at the evidence and reached one conclusion: you've been poisoned. And it's taking action. In this video: what your eyes and your inner ear are telling your brain in the back seat, and why they're telling it two completely different stories... the leading scientific theory for why that disagreement ends with you reaching for a bag, and what it has to do with the poisonous plants and spoiled meat your ancestors sometimes ate... why the driver almost never gets sick in the same car on the same road... why reading in the back seat is the worst thing you can do, why toddlers barely get motion sick but kids get it the worst, and why sailors, astronauts and VR gamers all suffer from the same ancient alarm... and the simple trick that works because it gives your brain back the one thing it's missing. Your ancestors never rode in anything faster than their own legs. The cars are new. The alarm is two million years old. 💬 Driver or passenger?
