Motion sickness is an unpleasant condition that occurs when persons are subjected to motion or the perception of motion. It results in the common symptoms of nausea, nonvertiginous dizziness, and malaise. It is generally considered to be of physiological origin. Nearly all individuals experience it if exposed to enough motion stimuli.

Although the motion associated with travel is the most commonly reported form of the syndrome, it has other names with slightly different characteristics. These similar conditions have been called sea sickness, travel sickness, space sickness, and cybersickness.
