Motion Sickness Causes
The cause of motion sickness is complex and not fully understood, but most experts believe that it arises due to conflicts in sensory input to the brain. The brain senses motion through different signaling pathways from the inner ear (sensing motion, acceleration, and gravity), the eyes (vision), and the deeper tissues of the body (proprioceptors). When the body moves involuntarily, such as when riding in a vehicle, there may be conflict among these different types of sensory input to the brain. The sensory apparatus in the inner ear seems to be most critical in the development of motion sickness.
Studies have shown that some people are more likely than others to experience motion sickness.
