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

The signs and symptoms of motion sickness usually begin with a feeling of uneasiness followed by cold sweats and dizziness. Some people may exhibit pale skin and increased saliva production along with headache and fatigue. Nausea and vomiting usually occur after these initial symptoms.

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.

Treatment for motion sickness can consist of medical treatment, simple changes in the environment (for example, sitting by the open window of a car), over-the-counter (OTC) medications and for some people, home remedies may be effective. In addition, some patients respond well to biofeedback training and relaxation techniques.
