Why Do I Get Travel Sick?

Motion sickness occurs when there's a conflict between sensory inputs to the brain. The brain relies on the inner ear, eyes, skin receptors, and muscles to determine movement. When these inputs disagree, such as when reading in a moving car, the brain becomes confused, leading to dizziness and nausea. Once the sensory inputs align, the symptoms subside.
