Seasickness is a form of motion sickness characterised by a feeling of nausea and, in extreme cases, vertigo, experienced after spending time on a craft on water.
This condition is caused by the rocking motion of the craft. Most people tend to concentrate on the inner surroundings,or close the eyes and try to sleep. This will cease the worst effect of the disturbance.
The brain receives conflicting signals: while the eyes show a world that is still, our body, and in particular the equilibrium sensors located in our ears, send signals of a moving environment. This discordance 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.
