Motion sickness occurs when your brain receives conflicting signals from your eyes, inner ear, and body. While using a MacBook in a moving car, your eyes focus on a stable screen, but your inner ear senses motion. This mismatch confuses the brain, leading to nausea, dizziness, and discomfort.

To reduce these symptoms, try positioning yourself where you can see outside the vehicle to help synchronize your visual and inner ear cues. Additionally, using an app like Carsick.app can adjust your MacBook’s visuals to align with the vehicle’s motion, reducing the conflict that causes motion sickness.
