Why does a day of video calls drain you more than in-person meetings? We explore the causes of digital fatigue and practical ways to reduce the cognitive load of constant screen communication.
Video calls are exhausting because they force us to process communication in an unnatural way. Unlike in-person meetings where attention naturally shifts between people and the environment, video platforms require continuous, intense focus on a screen. They create the illusion that all participants are looking directly at you simultaneously, while your physical mobility is strictly limited by the camera's frame. This combination of factors creates a specific type of strain that accumulates throughout the day.
During an in-person meeting, people look at the speaker, take notes, or glance at the window. On a video screen, colleagues' faces are grouped closely together, and everyone appears to be looking straight ahead. This creates the visual illusion that you are under the constant scrutiny of dozens of people at once, which requires extra effort to maintain social engagement.
Seeing your own face in real time during a conversation is an atypical experience. The constant presence of a window showing your own image forces part of your attention to shift to self-monitoring: how you are sitting, what your facial expression is, how the light falls. This doubles the cognitive workload, as you are simultaneously monitoring the other person and yourself.
When talking on the phone or chatting in an office, people often walk around, gesture, or change their posture. A video call ties a person to the narrow field of view of the camera. The need to constantly stay in frame restricts natural movements that usually help us release tension and maintain concentration.
We are used to reading body language, breathing, and micro-expressions without conscious effort. Through a screen, these signals are distorted by connection delays, poor lighting, or the fact that only the head and shoulders are visible. You have to spend more mental energy to figure out if the other person agrees, is listening, or if the internet has simply frozen. You can read more about the differences in communication formats in the article Online Communication vs In-Person: What We Lose in Messaging.
Consider an illustrative example. Anna has four consecutive video calls scheduled. By the third hour, her head feels heavy. When a colleague falls silent after her proposal, Anna becomes anxious, interpreting the silence as disapproval, even though the colleague is actually just reading a document on another monitor. Anna spends energy keeping a "professional face" for the camera, unable to stand up and stretch. By the end of the day, she feels completely drained, even though she hasn't physically left her room. In an office, between these same meetings, she would have walked down the hall, gotten some water, and exchanged a few words with colleagues, giving her time to transition.
People may mistake fatigue from video calls for a loss of interest in their job or laziness. If you are questioning the reasons for your state, the article Am I Just Lazy Or Is It Depression? might be helpful. It is important to understand that "Zoom fatigue" is not a medical diagnosis. It is a descriptive term for a specific stressor. Stress and anxiety can have overlapping symptoms, and fatigue in response to intense cognitive load is an expected reaction. Not all distress should be labeled as a disorder, but it is important to identify the patterns that cause tension so you can manage them.
If your job requires constant connectivity (which often leads to what is known as Digital Burnout), you can adapt your environment:
Sometimes the exhaustion from working in front of a screen can be part of a larger issue. If distress persists for a long time, interferes with your daily life, disrupts your sleep, or causes constant anxiety before the workday begins, it may be helpful to seek professional help. Psychotherapy involves working with a trained professional. For example, in Cognitive Behavioral Therapy (CBT), one can explore the connections among interpretations (e.g., "If I turn off my camera, they will think I'm not working"), feelings, and behavior. When choosing a provider, it is useful to ask about their qualifications, their methods, and how you will track progress.
