Sea sickness is a form of motion sickness which is experienced when we go on a long travel on the sea . It is caused because the sensory inputs to our brain are incongruous when we are on a cruise .
The boat on sea would be floating on water with upward and downward motion on water . But only boat is moving . Not the inside things on boat .
Our eyes send signal to brain as we are stationary by looking at surroundings . At the same time , our ears sense motion of boat and likewise they send signal to brain .
Brain is now confused by getting two different signals at the same time . It thinks that we are hallucinating . It thinks that this hallucination is the effect of poison .
So it induces nausea or drowsiness in an attempt to get rid of the poison and it is called SEA SICKNESS .
