Dr. Huberman says, "There's a known phenomenon in the visual system, whereby when we look at things up close, the lens of our eyes has to move in and the pupils dilate. It's a process called accommodation... when we're stressed or even if we just have a heightened state of alertness and attention, the pupils also dilate and that's in order to be able to track whatever it is that's stressing us in our environment and make everything else fade away."
That's a digital concussion...
There is an answer, Dr. Huberman explains, "The remedy is to make sure that you're getting some time each day—ideally, an hour or more—viewing things off in the distance. You can't just spend all day and all night on your screen and then expect your visual system to relax. It's like a muscle that's having to work really, really, really hard."
While we are working from home, we get stuck in these intense, attention-consuming modes. That can have profoundly negative physical and emotional consequences.
So, every day, spend at least an hour looking off into the distance. If you can get outside safely, do it. But even if you only look out the window, make sure you relax and look towards the horizon.
