Why get car sickness?

Car sickness, a type of motion sickness, occurs when there is a disconnect between what your inner ear senses and what your eyes see. When you're in a moving vehicle, your inner ear detects motion, but if you're reading or looking at something inside the car, your eyes may not perceive the same motion. This sensory mismatch can lead to symptoms like nausea, dizziness, and sweating. Factors such as anxiety, poor ventilation, and predisposition to motion sickness can exacerbate these symptoms.
