Motion sickness is characterized by the symptoms of nausea and vomiting. Nausea and vomiting can be caused by motion itself or simply from feeling the sensation of motion, as when watching a movie or playing a video game.
Balance and equilibrium are maintained by an interaction among the inner ears, the eyes, pressure receptors on the skin, and motion receptors in the muscles and joints.
Motion sickness results when conflicting messages regarding spatial orientation and motion of the body are sent to the central nervous system. For example, reading a book while riding in a car may cause your eyes to send different messages than your inner ears do regarding motion.
