What is Motion Sickness?

   
If you sometimes feel nauseous, dizzy, or even feel like vomiting when riding in a car, plane, or boat, you may suffer from motion sickness. Motion sickness is related to your sense of balance, which is maintained by the complex interaction of signals from your inner ear and various senses (sight, touch, smell, etc). Together, they tell your brain where your body is in space—in what direction you’re heading, whether you’re turning or standing still. These signals sometimes get confused. For instance, if you’re reading in the back seat of a car, your inner ear and skin receptors feel the motion of the car, but your eyes are focused on the page. The result may be motion sickness.
