Question

Why do you get motion sickness while travelling in a car?

Answer 1

Motion sickness occurs while travelling in a car due to the movement and continuous disturbance of the fluid present within the semicircular canals and vestibule of the inner ear. As the vehicle turns, accelerates, or navigates uneven terrain, the moving fluid stimulates sensory hair cells to send balance impulses to the brain; when these signals conflict with visual sensations or persist erratically, the brain experiences sensory disorientation, producing dizziness and nausea.
