What is motion sickness?

Motion sickness is the feeling you get when the motion you sense with your inner ear is different from the motion you visualize. It is a common condition that occurs in some people who travel by car, train, airplane or boat. Many people suffer from this condition if they ride on a roller coaster or other similar amusement park rides. Motion sickness progresses from a feeling of uneasiness to sweating and/or dizziness. This is usually quickly followed by nausea and/or vomiting.

Who is at risk for motion sickness?

Although pregnant women and children are more susceptible to motion sickness, almost anyone that is traveling is at risk for motion sickness. For those people who travel on boats, seasickness can be considered a form of motion sickness. Other risk factors include the person's fear or anxiety about traveling, the mode of travel, poor ventilation in the traveling vehicle, and the inability to see out of a window to aid orientation.

What are causes of motion sickness?

Motion sickness is caused by the mixed signals sent to the brain by the eyes and the inner ear (semicircular canals). If you cannot see the motion your body's feeling, or conversely, if you cannot feel the motion your eyes see, then it is likely that the brain will get mixed signals and the person will develop some aspect or symptom of motion sickness.
