When an aircraft encounters turbulence, the bouncing and shaking that results can cause passengers to experience some unwelcome familiar feelings: dizziness and an upset stomach, followed by a wave of nausea. (A)Unpleasant as it may be, motion sickness is a normal bodily reaction experienced by millions of people. Common symptoms of motion sickness include pale skin, cold sweats, and dizziness, usually followed by drowsiness, a flooding of salivainto the mouth, nausea, and even vomiting. It generally occurs in situations that involve movement—including traveling by car, boat, airplane, or train—and has even occurred among astronauts traveling through outer space, where it is known as microgravity nausea. Motion sickness can also be caused by other factors, such as anxiety, unpleasant odors, or a lack of fresh air. Although no one is completely immune, some people can resist the symptoms better. Individuals strongly affected by motion sickness sometimes take antihistamines before they travel, which seem to obstruct the confused signals the inner ear is trying to send to the brain. Others rely on home remedies, such as chewing on ginger. Once motion sickness has begun, however, there is little that can be done to alleviate the symptoms. The most effective measures seem to be keeping one's head still, staring at the horizon, and attempting to relax. Reducing the disparity of the sensory information the brain is receiving speeds the body's natural adjustments, effectively hastening the end of a bout of motion sickness.
