Motion sickness on a bus happens when your brain gets confused by conflicting information from your senses. The bus's movement is registered by your inner ear, but your eyes focus on a still MacBook screen. This sensory conflict often leads to nausea and dizziness.

To alleviate these symptoms, position yourself near the front of the bus and look out the window regularly. Carsick.app is also a helpful tool, designed to sync your MacBook’s screen with the bus’s motion, thereby reducing the visual-vestibular mismatch that causes motion sickness.
