Motion sickness is a normal response to real, perceived, or even anticipated movement. People tend to get motion sickness on a moving boat, train, airplane, car, or amusement park rides. Although this condition is fairly common and often only a minor nuisance, it may be incapacitating for people who travel frequently -- although the more you travel, the more you get used to the motion.



The most common signs and symptoms of motion sickness include:



鈥ausea

鈥aleness of the skin

鈥old sweats

鈥omiting

鈥izziness

鈥eadache

鈥ncreased salivation

鈥atigue



Motion sickness occurs when the body, the inner ear, and the eyes send conflicting signals to the brain. This most often happens when a person is in a moving vehicle such as a car, boat, or airplane, but it may also happen on flight simulators or amusement park rides. From inside a ship's cabin, the inner ear may sense rolling motions that the eyes cannot see, and, conversely, the eyes may see movement on a "virtual reality" simulation ride that the body does not feel. Interestingly, once a person gets used to the movement and the motion stops, symptoms may return (although usually only briefly). Sometimes just anticipating movement can cause anxiety and symptoms of motion sickness. For example, a person who had previously had motion sickness might become nauseous on an airplane before take-off.



The following are the most common risk factors for motion sickness:



鈥iding in a car, boat, airplane, or space shuttle

鈥oung age -- children ages 2 - 12 are most likely to get motion sickness.

鈥usceptibility to nausea or vomiting

鈥eightened level of fear or anxiety

鈥oor ventilation in the vehicle

鈥itting in the back seat or where you cannot see out the window



Most people who have had motion sickness in the past ask their health care provider how to prevent it next time. Your doctor will ask about your symptoms and find out what usually causes the problem (such as riding in a boat, flying in a plane, or driving in car). Laboratory tests are generally not necessary to establish a diagnosis of motion sickness.



There are several ways you can try to prevent motion sickness:



鈥it in the front seat in a car.

鈥eep your eyes on the horizon. Don't read.

鈥est your head against the seat back, to keep it still.

鈥urn the air vents toward your face.

鈥on't smoke.

If you have motion sickness on a plane, try these tips:



鈥void big, greasy meals and alcohol the night before air travel.

鈥at light meals or snacks that are low in calories in the 24 hours before air travel.

鈥void salty foods and dairy products before air travel.

鈥it toward the front of the aircraft or in a seat by the wing.

鈥urn the air vent flow toward your face.

If you have motion sickness on a boat, try these preventive measures:



鈥sk for a cabin on the upper deck or toward the front of the ship.

鈥hen on deck, keep your eyes fixed on the horizon or visible land.



You can use medication to control your symptoms, but people who travel often will want to learn to control -- and eventually prevent -- these symptoms. Mind-body practices, such as cognitive-behavioral therapy and biofeedback, may help. Other alternatives to medication include homeopathy, acupuncture, dietary supplements, dietary changes, and physical exercise.



Medications

Medications for motion sickness may cause drowsiness and impair judgment. Pilots, ship crew members, or anyone operating heavy equipment or driving a car should not take them. The following medications may be helpful to people who experience motion sickness motion sickness occasionally:



鈥ollowing these nutritional tips may help reduce symptoms and improve overall health:



鈥void spicy, greasy, or fatty meals.

鈥on't overeat.

鈥rink plenty of water.

鈥ry crackers and carbonated drink (such as ginger ale) help some people avoid nausea.Fluid in your inner ear is sloshing around upsetting your balance. Google "inner ear balance" for a full explanation.
