Question

What causes car sickness?

Answer 1

The most common hypothesis for the cause of motion sickness is that it functions as a defense mechanism against neurotoxins.[7] The area postrema in the brain is responsible for inducing vomiting when poisons are detected, and for resolving conflicts between vision and balance. When feeling motion but not seeing it (for example, in a ship with no windows), the inner ear transmits to the brain that it senses motion, but the eyes tell the brain that everything is still. As a result of the disconcordance, the brain will come to the conclusion that one of them is hallucinating and further conclude that the hallucination is due to poison ingestion. The brain responds by inducing vomiting, to clear the supposed toxin.

Answer 3

Motion sickness is caused by a conflict between your inner ear sensing motion but your eyes not seeing motion. Things like reading books, where you're not looking at motion will cause you to get motion sickness. The best thing to do is simply look at the scenery around you as it goes by (sorry, but it's true). This will eliminate the conflict and will keep you well.
