why do some people get 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
and/or. This is usually quickly followed by and/or. Although women and children are more susceptible to motion sickness, almost anyone that is traveling is at risk for motion sickness.


For those people who travel on boats, seasickness can be considered a form of motion sickness. Other risk factors include the person's fear or about traveling, the mode of travel, poor ventilation in the traveling vehicle, and the inability to see out of a window to aid orientation. 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.


The signs and symptoms of motion sickness usually begin with a feeling of uneasiness followed by sweats and. Some people may exhibit pale skin and increased saliva production along with and. and usually occur after these initial symptoms. In most cases, a doctor doesn't need to be called for motion sickness unless the person starts to develop from persistent and intractable vomiting.


In most people, once the motion has stopped, the symptoms slowly decrease and then disappear. In general, motion sickness is diagnosed by the patient's history and physical examination. The individual's description of symptoms and the context in which they occur is most often sufficient to make the diagnosis. Laboratory testing is not generally required. 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. I think it's more genetic than related to age. None of the people on my mom's side of the family (myself included, unfortunately) can read in cars or be on moored boats for any length of time. I haven't been able to concentrate on something inside a car since cI cna remember.


My dad's side doesn't have this problem. I have noticed that it's gotten worse as I get older but I think that's more due with lack of exposure to motion sickness causing activities than age. When I was a child I was always the passenger in a car and often had to ride in the rear. I also had more opportunites for outdoor boat related activites and amusement park rides. As an adult, I am almost always the driver and spend less time on the water so I'm less accomstomed to the motion.
