Scientists have explained the cause behind a phenomenon known as Zoom Fatigue. Using video or moving backgrounds during Zoom calls can increase mental and physical tiredness during virtual meetings, research suggests. Unlike still images or blurred backdrops, video backgrounds continuously present new information that demand a person’s attention and brainpower. This, in turn, can add to a worker’s “Zoom fatigue” – a form of physical and mental exhaustion that comes from frequently participating in video conference calls.
Findings published in the journal Frontiers in Psychology suggest that people who use nature-themed or light-hearted backgrounds report having lower levels of fatigue after online meetings compared with those using other types of virtual backdrops or not using any. Lead author Heng Zhang, a researcher at the Nanyang Technological University Wee Kim Wee School of Communication and Information in Singapore, explained that image backgrounds initially present new information, but users may gradually shift their attention elsewhere. Blurred backgrounds don’t introduce new information, but occasionally present glimpses of the real environment, which also demands attention. Video backgrounds, on the other hand, continuously introduce new information, constantly interrupting users’ attention and cognitive resources.
Previous research has shown that people on video calls spend a lot of time looking at themselves and analysing how they come across during the meetings, leading to mental exhaustion. In a recent study, researchers carried out a survey with over 600 workers aged between 22 and 76 who worked from home around three days a week. They were asked about their use of virtual backgrounds – static image, blurred image, or video backdrops – and their fatigue levels were measured on a five-point scale in various aspects.
The majority of people used virtual backgrounds during video calls, with still images being the most favoured choice. Among those using still images, nature-themed ones were popular, followed by interior spaces and workplace photos. A minority opted for abstract images and light-hearted backgrounds, with those using “funny” backgrounds reporting lower video call fatigue. The researchers suggest that funny backgrounds may reduce stress about self-presentation, leading to lower fatigue compared to more serious virtual backdrops.
Mr Zhang added that backgrounds such as office settings or public spaces can increase pressure to self-present, causing increased fatigue. In work settings, a nature-themed image background might be the ideal choice for reducing video call fatigue. This research sheds light on the impact of virtual backgrounds on mental and physical exhaustion during video calls, providing insights for improving online meeting experiences and reducing Zoom fatigue.
These findings could help workers and organisations better understand the effects of video call settings on fatigue levels, potentially leading to improvements in virtual meeting practices for enhanced productivity and well-being.
