Video calls have become a new normal in the era of remote work, but recent research indicates that using video or moving backgrounds during virtual meetings may lead to increased mental and physical exhaustion. Scientists have identified that video backgrounds, unlike still or blurred images, continuously introduce new information that demands attention and cognitive resources, contributing to what is known as “Zoom fatigue.” This form of exhaustion results from frequent participation in video conference calls.
In a study published in the journal Frontiers in Psychology, researchers found that individuals using nature-themed or light-hearted backgrounds reported lower levels of fatigue post online meetings compared to those using other types of virtual backdrops or none at all. Lead author Heng Zhang from the Nanyang Technological University Wee Kim Wee School of Communication and Information in Singapore explained that while still images and blurred backgrounds may shift attention gradually, video backgrounds constantly interrupt users’ focus by presenting new information.
Past studies have shown that individuals on video calls often spend time scrutinising their own image, leading to mental tiredness. The recent research surveyed over 600 workers aged 22 to 76 who worked from home around three days a week. Participants were asked about their use of virtual backgrounds, including static images, blurred images, or video backdrops, and rated their levels of general, visual, social, motivational, and emotional fatigue on a five-point scale.
The findings revealed that over 70% of respondents used virtual backgrounds during video calls, with nature-themed still images being the most popular choice. Those using light-hearted or abstract backgrounds reported lower video call fatigue than those with office or public space settings, as the former may reduce the stress associated with self-presentation in a work environment. Mr Zhang suggested that nature-themed backgrounds could be the most suitable choice for virtual meetings in a professional setting.
The researchers emphasised the impact of virtual backgrounds on cognitive resources and highlighted the importance of selecting backgrounds that minimise interruptions and maintain focus during video calls. These findings shed light on the factors contributing to ‘Zoom fatigue’ and provide insights into ways to mitigate the physical and mental exhaustion associated with virtual meetings.
