Travel dizziness: what to know

A rocking or spinning feeling during a car, boat, or flight may reflect a mismatch between what your eyes see and what your balance organs sense. Lightheadedness after standing can follow heat, dehydration, low food intake, or a drop in blood pressure. Dizziness that continues away from travel may need assessment for anaemia, an inner-ear condition such as benign paroxysmal positional vertigo, an irregular rhythm such as atrial fibrillation, or anxiety.

Sit or lie down when symptoms start and rise slowly once steady. Keep your head supported, look at a stable distant point, and choose fresh air where possible. Drink regularly and eat a small snack if you have gone without food, unless you have been given different instructions for diabetes. Avoid driving, heights, or swimming while dizzy. Note when symptoms begin, how long they last, and whether turning your head, standing, heat, or meals affect them.

Call emergency services for sudden one-sided weakness, facial drooping, trouble speaking, severe chest pain, fainting, a new severe headache, or difficulty walking. Seek prompt care for repeated vomiting, a racing or irregular heartbeat, confusion, or dizziness after heat exposure that does not settle with rest and fluids. Arrange a review when episodes recur or happen without movement.

Ask whether your description suggests motion sickness, lightheadedness, or vertigo; whether blood tests, blood-pressure checks, or an ear assessment are needed; and which travel medicines are safe with your current treatment.
