What is motion sickness?
By Dr Ananya Mandal, MD
Motion sickness, also termed kinetosis, is a generalized term that is used to describe an unpleasant set of symptoms like nausea, vomiting and dizziness that occurs when a person is travelling.
As the travel course progresses the symptoms may improve while the body adapts to the conditions leading to the sickness.
