Motion sickness happens when your eyes, inner ear and body send your brain conflicting signals about movement. Reading in a car, for example, tells your eyes you’re still while your inner ear feels every bump. The result can be nausea, dizziness, cold sweats and vomiting. It’s common in cars, boats, planes, trains and even VR headsets, and children aged 2 to 12 are especially prone to it.
Prevention tips that work
- Pick the steadiest seat. Front seat in a car, over the wing on a plane, the middle of a boat near the waterline, or a forward-facing seat on a train.
- Look at the horizon. Fixing your eyes on a stable, distant point helps your eyes and inner ear agree.
- Avoid screens and reading while moving.
- Get fresh air. Open a window or point an air vent at your face.
- Eat light. Have a small, bland meal before travelling. Avoid heavy, greasy or spicy food and alcohol.
- Stay hydrated with small sips of water.
- Take breaks on long car journeys.
Medicines for motion sickness
Over-the-counter antihistamines like dimenhydrinate (Dramamine) are the most common treatment. They work best when taken before symptoms start:
- Take the first dose 30 to 60 minutes before you set off.
- Adults and children 12+: 1 to 2 tablets (50 to 100 mg) every 4 to 6 hours, no more than 8 tablets in 24 hours.
- Children 6 to 11: ½ to 1 tablet every 6 to 8 hours, no more than 3 tablets in 24 hours.
Dramamine causes drowsiness. Don’t take it if you’re the one driving, and avoid alcohol while using it. Ask a doctor first if you have glaucoma, breathing problems, or trouble urinating due to an enlarged prostate.
If you already feel sick
- Stop reading or using your phone, and close your eyes or look at the horizon.
- Recline your seat and keep your head still.
- Sip cold water or nibble a plain cracker.
- If possible, stop and get out for a few minutes of fresh air.
When to see a doctor
See a doctor if you have dizziness or vertigo when you’re not travelling, symptoms that continue for long after the journey ends, or if you’re pregnant and need motion sickness treatment.
