What motion sickness means for travellers

Cars, aircraft, boats and amusement rides can all produce changing movement signals. The brain receives information from the eyes, inner ear and body position sensors that does not fully agree. Nausea may come with cold sweating, pale skin, salivation, headache, dizziness or vomiting. Symptoms commonly improve when the motion ends.

Choose a position with a steady view and less movement, face forwards, support your head and avoid reading. Fresh air, slow breathing, light food and small sips of water may help. Plan breaks on road trips and keep supplies nearby so you can respond at the first sign of nausea.

A pharmacist or doctor can advise whether preventive medicine is suitable, including for children, pregnancy and people with other medical conditions. Some medicines cause sleepiness or blurred vision; check the label and avoid driving until you know how you respond.

Seek urgent care for fainting, confusion, severe headache, chest pain, weakness, trouble speaking, new hearing or vision changes, or vomiting that prevents fluid intake. A clinician should assess dizziness that persists after travel, occurs without motion, or keeps returning unexpectedly.

Ask which seat or position may suit your route, whether medicine is safe with your current treatment, how far in advance to take it, and what warning signs should change your travel plans.
