Car sickness is caused by mental confusion
Do you feel nausea or stomach discomfort while riding a car or a bus? Believe me, it's more common than it looks. According to neuroscientist Dean Burnett, this nausea is due to a confusion in the brain, which does not know whether you are moving or standing - and believes that you may be poisoned.
Burnett explains that, because the muscles are relaxed as the eyes see the movement, the inner ear liquids indicate to the part of the brain, the thalamus, that you are in locomotion. This causes mental confusion and the brain believes that such an effect is due to neurotoxins or poisoning.
This perception causes the brain to send signals so that the stomach eliminates possible substances, consequently causing nausea. According to Burnett, looking through the window would relieve the symptoms by balancing the opposing stimuli that the body receives, and would be more appropriate than reading during travel, for example.
Hypochondriac is the one who has medicine mania, right? Wrong.
