Experiencing nausea during a commute while using your MacBook is a common form of motion sickness. It occurs because your eyes are focused on a static screen, while your body feels the movement of the vehicle. This creates a mismatch in sensory information, leading to nausea.

To alleviate this, try using your MacBook in short intervals and look out the window periodically. You can also use Carsick.app to sync the screen’s movement with the motion of the vehicle, helping to reduce the chances of feeling nauseous.
