Why Video Calls Wear People Out Faster Than Meetings

A director I coached described her days accurately without meaning to: she said a six hour day of video calls left her more exhausted than a twelve hour day of theater rehearsal used to, back when she directed on stage. That comparison stuck with me, because rehearsal is physically demanding in a way a video call obviously is not, and yet the fatigue she described was real, measurable, and specific to the screen.

The usual explanation is screen time, but that explanation does not fit the evidence well. People spend hours on screens reading, watching, and working without the same exhaustion a video call produces in the same span. Something about the specific format of a video call, not screens generally, is doing the damage, and understanding what that something is changes how you can actually reduce it, rather than just cutting call time and hoping.

The eye contact problem nobody designed for

In a real conversation, eye contact is intermittent. You look at the other person, then away, then back, dozens of times a minute, without noticing you are doing it. Video calls remove that natural rhythm, because the camera sits above the screen while the other person's face sits in the middle of it, so looking at their eyes on screen means you are not looking at the camera, and looking at the camera means you cannot see their face. Most people resolve this by staring at the screen continuously, producing a level of sustained eye contact that would be unusual and intense in person, held for the entire length of a call.

Sustained eye contact at that duration is cognitively expensive, and it does not register consciously as strange, because everyone on the call is doing the same thing to each other. The body still processes it as an unusually intense social interaction, though, which is a large part of why a string of thirty minute video calls produces a kind of tiredness that a string of thirty minute in person conversations does not.

The extra job nobody notices they are doing

There is a second cost that is easier to overlook. In an in person meeting, you receive information about the room without processing it deliberately, who else is present, their posture, the general mood, all absorbed peripherally. On video, gathering the same information requires active attention, watching a grid of small faces for cues that would be automatic in a shared physical space. That constant low level scanning is genuine cognitive work, and it runs continuously through the entire call, on top of whatever the meeting's actual content requires.

Add to that the awareness of one's own video feed, which most platforms display prominently, and you get a third task running in parallel: monitoring your own appearance and expression in real time, something no in person meeting ever asks of you, because you cannot see your own face while you are in a room with other people.

Where the standard fix falls short

The common advice is to take more breaks or shorten meetings, and both help somewhat, but they treat the symptom rather than the structural cause. A five minute break between two thirty minute video calls does not undo the sustained eye contact cost that accumulated during either call, it just delays the next dose. Shortening a meeting from sixty minutes to thirty helps more, but a day with eight thirty minute calls can still produce as much fatigue as a day with four hour long ones.

What actually reduces the load is turning off self view, which removes the third task entirely, and normalizing camera off or gallery minimized for calls that do not genuinely require reading facial expression, such as a status update or a routine check in. Neither change costs anything, and both are resisted in most organizations because camera off has picked up an unfair reputation for disengagement, even though the evidence for that association is thin.

A camera on a call is not automatically a sign of attention. It is often a sign of performance, and performing attention for six hours a day is exactly what produces the exhaustion in the first place.

The director eventually restructured her week around this, keeping camera on only for the two calls a day that genuinely needed facial read, casting decisions and difficult notes sessions, and defaulting to audio for everything else. She described the change as getting roughly two usable hours back in a day, not from shorter meetings, but from removing tasks that were never necessary in the first place.

If your calendar is full of video calls, try one week with self view off and camera optional for anything that is not a genuinely relational conversation. The savings tend to show up faster than people expect, in the same way that a small structural fix shows up in the email that gets answered in one reply, another case where the format of a message, not its content, was quietly doing most of the damage. Both live under digital communication, where small design choices carry more weight than most people assume.
