Travel headache: what to know

A changed sleep schedule, long screen use, neck strain, or skipped meals can trigger a tension-type headache. Dry cabin air, hot weather, and inadequate drinking can contribute to dehydration. Pressure changes may cause forehead or facial discomfort, especially with a blocked nose or sinus inflammation. Headache with fever, cough, or loss of smell may occur with a common cold or COVID-19; in a dengue-risk area, fever and marked body aches require prompt local medical advice.

Drink water regularly, eat at usual intervals, and take breaks from screens. Rest your neck, reduce glare and strong smells, and seek a cooler, quieter space. Saline nasal care may ease congestion for some people. If you normally use a pain reliever, follow its label and check with a pharmacist if you have kidney disease, stomach ulcers, are pregnant, or take blood thinners. Avoid taking pain medicine repeatedly without advice because frequent use can maintain headaches.

Get emergency help for a sudden explosive headache, new weakness, confusion, fainting, seizure, stiff neck with fever, vision loss, or trouble speaking. Seek prompt advice for headache after a head injury, persistent vomiting, severe heat-related symptoms, or fever after travel to a region where dengue occurs. Arrange a review if headaches are new, recurrent, or progressively different from your usual pattern.

Ask whether your pattern fits tension, sinus pressure, migraine, or another cause; which pain relief is safe for you; and what symptoms should stop you travelling or prompt urgent care.
