What should you know about motion sickness after flying?

During a flight, your inner ear detects acceleration, turns, and turbulence while your eyes may see the steady interior of the aircraft. This mismatch can cause nausea, dizziness, sweating, headache, and vomiting. Anxiety, dehydration, missed meals, or another illness can intensify the feeling. Symptoms that begin after landing may also reflect a problem unrelated to motion, especially when fever, diarrhoea, or severe pain is present.

Sit somewhere safe, keep your head steady, and breathe slowly in fresh or cool air. Sip fluids regularly and eat a small light meal when able. Avoid driving until dizziness has cleared. For another flight, choose a seat with less movement when possible, look toward the horizon or a distant fixed point, and ask a clinician or pharmacist about prevention before travel.

Get urgent help for fainting, confusion, chest pain, breathing difficulty, a severe headache, weakness on one side, blood in vomit, or inability to keep fluids down. Seek medical advice if symptoms last beyond the expected settling period, repeatedly return at rest, or are accompanied by fever, persistent abdominal pain, or severe dehydration.

Ask whether the episode sounds like motion sickness, dehydration, migraine, or another condition. Discuss prevention medicines, possible drowsiness, interactions with your current treatment, and what symptoms should stop you from driving or flying again.
