Motion sickness - Movement sickness or travel sickness

Generality

Motion sickness is a general term for a combination of unpleasant symptoms - such as dizziness, nausea, and vomiting - that occur as a result of repetitive or irregular movements of the body. It is a neurological disorder that derives from the contrasting interpretation of the signals coming from the vestibular (inner ear), visual and proprioceptive systems.

Motion sickness often occurs during a trip, in fact it is also known as seasickness, car sickness or air sickness (induced by air travel). In most cases, symptoms improve as the body adjusts to the conditions causing the problem. For example, if motion sickness occurs during a stay on a cruise ship, malaise can improve within a couple of days. However, some people may find it more difficult to adapt and experience a persistent sense of discomfort until the stimuli stop. Any type of transport can cause motion sickness and everyone can potentially suffer from the disorder, but some people are more susceptible than others. While motion sickness is often a minor nuisance, it can be a problem for people who frequently have to travel.
