• Zoom calls can be mentally exhausting due to the constant need to maintain eye contact, stay focused, and process nonverbal cues. According to a study by researchers at Yale University, the cognitive load of video conferencing is significantly higher than in-person interactions, leading to increased feelings of fatigue and stress.

• The study found that the brain has to work harder during Zoom calls to process the limited visual and auditory information available, as well as the lack of physical cues that are present in face-to-face interactions. This can lead to a phenomenon known as "Zoom fatigue," where individuals experience a sense of depletion and decreased productivity after prolonged video conferencing.

• To mitigate the negative effects of Zoom calls, the researchers suggest taking regular breaks, limiting the number of video meetings, and incorporating physical activity into the workday. Additionally, they recommend optimizing the video conferencing setup, such as adjusting the camera angle and lighting, to create a more natural and comfortable environment for participants.
