Article in English: Motion sickness is likely caused when involuntary movement (as in a car or boat) confuses the brain, which normally senses movement by signals coming from the inner ear, eyes, and surface receptors. It is a common problem. If you are prone to motion sickness and vomiting, one way to avoid a dangerous situation is to avoid driving.
