What causes car sickness and who gets it?

The exact answer to these questions is unknown. There is more than one theory. It is however most widely accepted to occur when there is sensory conflict during motion. The sensory conflict arises when the detection of motion by the different sensory organs namely the inner ears, the eyes and the input from the skin and muscles conflict with one another. An example of this is when a child is seated in the back seat, facing the parent’s seat, reading a book or watching a movie. During this period the inner ear will detect motion but the eyes that are not following the surroundings outside the vehicle not. This conflict in sensory input, confuses the brain leading to car sickness. Car sickness may represent an early form of migraine. It may also occur more commonly when the child is excited or anxious.
