I don’t think anyone will be surprised to hear that we now have brain scan research that shows that Zoom fatigue is a real thing:

The brain and heart readings suggested that videoconferencing led to significantly greater signs of fatigue, sadness, drowsiness, and negative feelings, as well as less attention and engagement, than a face-to-face lecture. The questionnaires also showed the volunteers felt significantly more tired, drowsy, and fed up and less lively, happy, and active from videoconferencing than face-to-face sessions.

Just so we don’t make the wrong conclusions based on this… the research does not mean that remote work is bad for you. It does mean that we need more communication to be asynchronous, and rely less on synchronous, office-analogous methods of communication when we work remotely.
