Seeing yourself on video calls leads to mental tiredness, Irish study finds

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 such as 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 study team carried out an experiment using electroencephalography (EEG) monitoring of 32 volunteers – 16 men and 16 women – all of whom participated in a live Zoom meeting, with the self-view mode both on and off at different times.

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 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.

Researchers said the findings not only contribute to the understanding of fatigue experienced as a result of the dramatically increased use of video conferencing, but also offer practical insights for organisations aiming to protect employee well-being.

“The use of video-conferencing platforms exploded during the lockdown,” Professor Eoin Whelan, of the University of Galway, said. “They continue to be heavily used 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.”
