WHY does motion sickness occur?
It is caused by a malfunction of the vestibular apparatus, responsible for keeping us firmly on feet.
It reacts to changes in the position of the head and body in space, as well as to acceleration.
When a person's body moves and sways in a car or on a boat, the brain receives conflicting information from the different senses, which causes nausea, dizziness, and headaches.
