Nausea while travelling

Your inner ears sense acceleration and turning while your eyes may see a steady page, cabin, or vehicle interior. That mismatch can cause nausea, dizziness, sweating, headache, and vomiting. Winding roads, rough water, looking down, warm air, strong odours, tiredness, and dehydration can make it worse. Fever or diarrhoea points toward an illness such as food poisoning or gastroenteritis rather than motion alone. Symptoms continuing after arrival should not automatically be attributed to travel.

Sit where movement is gentler, face forward, and look at a distant stable point. Support your head, keep fresh air moving, and avoid reading or using a phone. Take small sips of water and choose light food instead of a heavy meal. If you know this happens to you, ask a pharmacist about suitable prevention before departure; some options can cause drowsiness, blurred vision, or a dry mouth.

Get urgent help for severe abdominal pain, fainting, confusion, chest pain, a severe headache, blood in vomit, repeated vomiting, or signs of serious dehydration. Seek advice if symptoms last beyond the journey, recur without movement, or come with fever, jaundice, weakness, or very little urine. Discuss prevention before travel if you are pregnant, have diabetes, or take medicines that affect alertness.

Ask how to prevent motion sickness on your route, whether a medicine is safe with your current treatment, and how to recognise dehydration.
