Seasickness

Motion sickness occurs in connection with travel or movement when an incongruity comes about between visually perceived movement and the vestibular system's sense of bodily movement. Most kinds are considered terrestrial motion sickness, such as being carsick, airsick, seasick, or sick from reality simulation. Symptoms include dizziness, fatigue, vertigo, depressed appetite, nonspecific malaise, gastrointestinal discomfort, (most commonly) nausea, and nausea-caused vomiting (see Sopite syndrome). If the cause of the nausea is not resolved, the sufferer will usually vomit, but vomiting may not relieve the feeling of weakness and nausea, which means the person might continue to vomit until the underlying cause of the nausea is resolved.

A specific type of motion sickness with similar symptoms but a possibly different etiology is space adaptation syndrome (sometimes referred to as space motion sickness). 'Nausea' in Greek means seasickness (naus means ship).
