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.

Clinical context
Looking at the horizon helps realign visual and inner ear signals
Focusing on a distant, stable point like the horizon helps bring what your eyes see back in line with what your inner ear is sensing about movement, which is why this is one of the most consistently helpful tips for reducing motion sickness.

Practical steps
Take Anti-Sickness Medication Before Symptoms Start, Not After
Motion sickness medication is generally much more effective when taken before a journey begins, as a preventive measure, rather than waiting until symptoms have already started.
- 1Look at a fixed point on the horizon.This helps realign visual and inner ear signals about movement.
- 2Sit in a position with the least movement.For example, the front seat of a car, over the wing of a plane, or on deck rather than below on a boat.
- 3Avoid reading or looking at screens while travelling.This can worsen the mismatch between visual and inner ear signals.
- 4Get fresh air if possible.This can help ease symptoms for some people.
- 5Take anti-sickness medication before travelling if needed.This works best when taken preventively, before symptoms start.
