Why Do We Get Seasick?
Seasickness is a disagreeable illness that is caused by the pitching and rolling motion of a ship at sea. It is a form of motion sickness characterized by a feeling of nausea and, in extreme cases, vertigo.
In our normal activities, three fluid-filled semi-circular canals in the inner ear enable us to keep our balance as we walk, run or ride a bicycle.
But the unfamiliar pitching and rolling of a ship’s deck disturb the little balance canals in the ear with too much movement, and we may soon begin to feel dizzy and sick to our stomach.
This disturbance causes the mind to send to the whole body a general alarm signal, in order to stop all activities, in particular the most complex of all, the digestion process.
The illness is much like carsickness, airsickness and train sickness – all of which are examples of the same motion sickness.
