Which reverses the usual advice about shortening meetings.
Tell it apart
| Aspect | Zoom fatigue | Burnout |
|---|---|---|
| Timescale | Hours | Months |
| Cause | One specific load | Multi-causal |
| Recovers overnight | Usually | No |
| Measured by | ZEF Scale | Several instruments |
Burnout is chronic, occupational and multi-causal. Zoom fatigue is acute and traced to specific features of the video call — close-up eye gaze, the work of sending and reading signals, watching yourself, and sitting still. One builds over months; the other arrives by four in the afternoon.
What it doesn't mean
A 2024 study across 489 students and 1,558 working professionals in Singapore and Germany found videoconference LENGTH had no significant relationship with communication overload, while FREQUENCY consistently did. Information overload behaved differently — there, frequency ran the other way or not at all. Fewer calls may beat shorter calls.
The same study found the mechanism differs by country: fatigue in Singapore was more communication-driven, in Germany more information-driven, and individualistic cultures showed stronger frequency-to-fatigue patterns.
What it really means
The standard advice is shorten your meetings. A large 2024 survey study says that is the wrong variable — one study, and a cross-sectional one, rather than a settled result.
A 2024 study across 489 students and 1,558 working professionals in Singapore and Germany found that videoconference length did not significantly influence communication overload in any of its samples — and did nothing consistent to information overload either, running slightly the other way in the German data.
Frequency did.
Which points somewhere awkward for the usual advice: on this evidence, six thirty-minute calls scattered across a day may cost more than one three-hour call. That is an inference rather than a result — the study measured associations at a single moment, never compared the two days directly, and found frequency running the other way for information overload, where more calls went with less of it. The proposed reason is that each call has a cost of entry that duration does not amortise: the switch, the greeting, the arrangement of your face, the recalibration.
The leading explanation for why any of this is tiring is Jeremy Bailenson's nonverbal overload, published in 2021, and it is specific rather than vague. Video calls demand sustained eye contact at a distance that in person would be intimate or hostile. They put a mirror in front of you for eight hours. They immobilise you inside a small frame. And they degrade nonverbal signalling enough that both sending and reading it takes conscious work.
None of that is present in a phone call, which is why phone calls are less exhausting despite carrying less information.
The effect is real enough to have a measurement instrument — a Zoom Exhaustion and Fatigue Scale — which is more than most workplace complaints achieve.
And one finding argues against treating this as a fixed human trait. The mechanism differed by country: fatigue in Singapore was more communication-driven, in Germany more information-driven, with individualistic cultures showing stronger frequency-to-fatigue patterns. Whatever this is, it is partly cultural, which means it is partly arrangeable.

Where it comes from
the platform, used generically
French fatiguer — to tire
The brand name is a genericisation — the phenomenon applies to any videoconferencing tool, which is why researchers prefer 'videoconference fatigue'.
- 2020
The term spreads during lockdowns; an online survey of 1,183 US respondents by the mattress-review site Tuck Sleep, published in May 2020, found 72% reported working from bed.
- 2021
Jeremy Bailenson publishes 'Nonverbal overload: A theoretical argument for the causes of Zoom fatigue', and researchers build a Zoom Exhaustion and Fatigue Scale.
In real life
- After six back-to-back video calls, she closed the laptop at four o'clock feeling more drained than after a full day in the office.
- 'Can we do this one as a phone call? I've got Zoom fatigue and I'd like to walk round the block while we talk.'
- Halfway through the call he realised he had spent more time watching his own face in the corner than looking at anyone else's.
Questions
Q01What causes it?
The most cited account is Jeremy Bailenson's 2021 'nonverbal overload' argument, which he published as a theoretical proposal rather than a tested finding: video calls make nonverbal signalling do work that being in a room together does not demand. Constant eye contact at unnatural distance, watching yourself, reduced mobility, and having to work harder to send and read signals.
Q02Do shorter meetings help?
A 2024 two-country study found call frequency, not length, predicted COMMUNICATION overload. For information overload the results were mixed and sometimes ran the other way. Fewer calls may beat shorter ones, but the evidence is narrower than the advice usually given.
Q03Can it be measured?
Yes, via a Zoom Exhaustion and Fatigue Scale. That is a research instrument, not a diagnosis — this page is educational, and persistent exhaustion is worth raising with a clinician.
