The connection between MacBook screen use and motion sickness lies in sensory conflict. When your eyes are locked on a still screen, but your body senses the movement of the vehicle, your brain struggles to reconcile the difference, leading to motion sickness symptoms.

Taking breaks, looking out the window, and adjusting your position may help reduce symptoms. You can also use Carsick.app, which aligns your MacBook’s visuals with the motion of the vehicle, reducing the mismatch and lessening the effects of motion sickness.
