If you've ever been sick
to your stomach on a rocking boat or a bumpy airplane ride, you know the
motion sickness. Although it doesn't cause long-term
problems, motion sickness can make life miserable, especially for people who
travel a lot.
People can feel sick from the motion in cars,
airplanes, trains, amusement park rides, or on boats or ships. Motion sickness
is sometimes called airsickness or seasickness. Video games, flight simulators,
and looking through a microscope also can cause motion sickness. In these
cases, the eyes see motion, but the body does not sense it.
Children from 5 to 12 years old, women, and the elderly seem to be more
susceptible to motion sickness, while it is rare in children younger than age
Common symptoms of motion
sickness are a general sense of not feeling well (malaise), nausea, vomiting,
headache, and sweating.
occurs when the
inner ear , the eyes, and other areas of the body that detect motion send
unexpected or conflicting messages to the brain. One part of your
balance-sensing system (your inner ear, vision, and sensory nerves that help
you keep your balance) may sense that your body is moving, while the other
parts do not sense motion. For example, if you are in the cabin of a moving
ship, your inner ear may sense the motion of big waves, but your eyes don't see
any movement. This leads to a conflict between the senses and results in motion
best to try to prevent motion sickness, because symptoms are hard to stop after
they start. After motion sickness has started, relief comes only after the
motion has stopped. If you can't stop the motion, you may be able to reduce the
feeling of queasiness by sitting or lying down in an area that appears to move
the least. In an airplane, sit near the wings. On a boat or ship, stay on the
deck, looking at the horizon. Or try to sit or lie down in a cabin near the
center of the ship.
