(FILES) Priscila Almiron, daughter of Covid-19 survivor Raul Almiron, shows an image of a family videocall on her mobile phone while her father was hospitalized, at their house in Florencio Varela, Buenos Aires province, Argentina, on April 13, 2021. Feeling drained after a video conference? Your fatigue could be partly linked to the background you choose to appear on the screen, according to a study published September 19, 2024, which recommends using nature landscapes. "Video" meetings at work, distance learning at university, virtual aperitifs with friends and Sunday video calls with grandparents... video conferences are now part of our daily lives. These new communication tools, the use of which has increased sharply since the Covid-19 pandemic, have given rise to a phenomenon known as "video conference fatigue" (VF) which manifests itself physically, emotionally, cognitively and socially.
