Nothing spoils a nice drive like the creeping feeling of car sickness, but don't get too mad - this queasiness could actually be an indication that your brain is working as it should be... sort of.

Recent research has found that car sickness could be the result of your brain responding to what it thinks is a sudden bout of poisoning.

No, the guy in the passenger seat didn't put something in your coffee - scientists have suggested that when you're in a car, your brain is getting conflicting messages about your immediate environment, similar to when you've been poisoned. And we all know that throwing up is the easiest way to flush any neurotoxins or poisons out of your system.

So what's going on here, and why are our brains so confused? 

Experts think that car sickness (or any kind of similar motion sickness) is brought on because humans have only recently started travelling in things like cars, buses, and boats, and our brains haven't fully adapted yet.
