What is Motion Sickness?

Motion sickness happens when there's a mismatch between what your eyes see and what your inner ear senses about movement, commonly occurring during travel by car, boat, plane, or train. It typically causes nausea, dizziness, and sometimes vomiting, and can affect anyone, though some people are more prone to it than others.

Motion sickness is uncomfortable but not dangerous, and a range of simple measures and, if needed, medication can help prevent or reduce symptoms, making travel more comfortable.
