Are you spending a lot of time learning, teaching, or meeting online these days? And do you find it puzzlingly exhausting?
There are things about video conferencing that we have not yet understood – or if we understand them, we haven’t incorporated them into the way we manage our days.
Our brains are deeply impressive, and really rather sneaky. They spend a lot of time processing things that we are completely unaware of. They are constantly scanning the world – for unexpected movement, for danger, for chocolate (or maybe that’s just mine), for the way people are behaving and reacting to us.
A whole lot of that scanning is never brought to our attention unless it really needs to be. My brain doesn’t need to tell me that there’s a room with no chocolate in it at all. But it absolutely does need to point out unexpected chocolate cake.
So for the most part we are unaware of all of the extra work that’s going on in our subconscious. We often even have emotional reactions to things we are not consciously aware of – a tightening in someone’s voice, a minute change in their posture, or an unexpected noise in the distance.
When I am in the same room as someone, I am absorbing a lot of information about them without knowing that I am. From their body language to really subtle things like all of the different frequencies in their voice. Someone’s whole body, taken head to toe, can tell me a lot, much of which I’m not even aware of processing, about how they are feeling and responding to me.
“Who said I was worried?” Glenda snapped.
“You did. Your expression, your stance, the set of your body, your…reactions, your tone of voice. Everything.”
“You have no business to be looking at my everything!”

Every aspect of your body language and voice is another piece of information. Unfortunately we lose a huge number of those pieces when we connect via video conferencing.
The quality of a video conferencing call means that we get, at best 30 frames per second. Think of video as a really good stop motion animation. It’s actually a series of still images – photos, really – that are taken so quickly and stitched together so well that it looks seamless. Like a flip book animation where the flipping is done perfectly evenly and at just the right speed. But the human eye can process a lot more frames than that – some evidence says up to 500, or even 1000 frames per second. Which means that, face to face, we’re getting a much more detailed impression of what’s going on. We’re seeing minuscule changes in facial expression, voice quality, and posture, that give us a massive amount of information about the person we’re dealing with.
In video conferencing we get less than a tenth of that detail (and that’s just the visual, never mind the audio quality). That’s assuming the network is coping and there’s no glitching.
So when you’re watching a video, or sitting through a zoom call, your brain is actually working fiercely hard, trying to make sense of what, to it, is an incredibly glitchy image, even if it seems smooth to you. It’s trying to fill in the gaps from frame to frame, work out what is missing, and understand information that simply isn’t there. It presents you, where possible, with a smooth and seamless experience, but it has to work incredibly hard to do so.
Sounds exhausting, doesn’t it? And that doesn’t take into account the fact that you can generally only see the head and shoulders, at most, of the people you’re meeting with (a whole lot more pieces of information gone missing), and there are network glitches, background noise, and interference that lower the video quality even further.
Most of what our brains do is outside our conscious control, or even our awareness. And right now, we have a huge amount of work to do that we’re not used to, and that we don’t even know we’re doing, just to try to relate to the people “around” us, and maintain our connections, relationships, and workflow. The duck that’s our brain appears to be swimming along happily, but it’s paddling so fast under the water that its little legs might just fall off.
There are so many reasons why what we’re experiencing is wearing us down, but online calls are more challenging than they seem. So cut yourself some slack. Schedule breaks in between your online meetings. And look away from the computer as often as you can. Knowing how hard your brain is working to make sense of the world seems a good reason to give it a rest!
