Asked by: Matthew Caruana, Malta
Motion sickness in general is caused when your inner ear and your eyes disagree about whether you’re moving. When you read in a car, your visual field stays still but your inner ear detects the twists and turns. This sensory conflict triggers nausea, possibly because the brain thinks you’ve eaten something toxic that’s making you hallucinate. About a third of us are more prone to motion sickness, with children aged 2-12, the elderly, migraine sufferers and pregnant women among the high risk groups.
