Seeing your own image during video conferencing calls leads to mental fatigue, according to a study of brain activity.
Academics at the University of Galway found that people who take part in meetings on apps like Zoom or Teams become more fatigued when they can see themselves on screen.
The research also revealed that men and women become equally fatigued when viewing their own image, contradicting previous findings which suggested women experience more fatigue from self-view video conferencing than men.
The researchers said EEG non-invasively records spontaneous electrical activity in the brain using electrodes placed on the head and can detect the onset of mental fatigue.
The monitoring confirmed that fatigue levels were significantly greater during the times participants could view their own image.
Previous research, which largely relies on self-reported data gathered through surveys and interviews, has suggested that women experience more Zoom fatigue than men.
Theories previously offered for this gender difference centre on a supposed increased self-awareness women have of their appearance when they view themselves in a mirror.
However, the University of Galway study, which measured fatigue at a neurophysiological level, questioned whether gender differences actually exist for video conferencing fatigue.
Professor Eoin Whelan, of the University of Galway, said: “The use of video conferencing platforms exploded during the lockdown.
“They continue to be heavily used in work and education today and offer some advantages over in-person meetings. But people often report feeling exhausted by video conference meetings.
“Our study shows that those feelings of fatigue you get during video calls are real, and seeing your own reflection makes it even more tiring. Simply turning off the mirror image can help offset fatigue in virtual meetings.”
