Your screen freezes. There’s a weird echo. A dozen heads stare at you. There are the work huddles, the one-on-one meetings and then, once you’re done for the day, the hangouts with friends and family.

Since the Covid-19 pandemic hit, we’re on video calls more than ever before – and many are finding it exhausting.

But what, exactly, is tiring us out? BBC Worklife spoke to Gianpiero Petriglieri, an associate professor at Insead, who explores sustainable learning and development in the workplace, and Marissa Shuffler, an associate professor at Clemson University, who studies workplace wellbeing and teamwork effectiveness, to hear their views.

Is video chat harder? What’s different compared to face-to-face communication?

Being on a video call requires more focus than a face-to-face chat, says Petriglieri. Video chats mean we need to work harder to process non-verbal cues like facial expressions, the tone and pitch of the voice, and body language; paying more attention to these consumes a lot of energy. “Our minds are together when our bodies feel we're not. That dissonance, which causes people to have conflicting feelings, is exhausting. You cannot relax into the conversation naturally,” he says.
