Motion Sickness

Back

Motion sickness is a sensation of wooziness. It usually occurs when you’re traveling by car, boat, plane, or train. Your body's sensory organs send mixed messages to your brain, causing dizziness, lightheadedness, or nausea. Some people learn early in their lives that they’re prone to the condition.

SYMPTOMS

Motion sickness usually causes an upset stomach. Other symptoms include a cold sweat and dizziness. A person with motion sickness may become pale or complain of a headache. It’s also common to experience the following symptoms as a result of motion sickness:

nausea
vomiting
loss of or trouble maintaining your balance

CAUSES

You maintain balance with the help of signals sent by many parts of the body — for instance, your eyes and inner ears. Other sensory receptors in your legs and feet let your nervous system know what parts of your body are touching the ground.
Conflicting signals can cause motion sickness. For example, when you’re on an airplane you can’t see turbulence, but your body can feel it. The resulting confusion can cause nausea or even vomiting.
