I have been teaching online for a long time now and am therefore continuously on the laptop from 7:30 a.m. To 1:00 p.m. In the afternoon I'm not even on the cell phone because that's too much for me. Lately I always feel dizzy when I sit in front of the screen, could that be due to too much screen time?
Yes it could.
Can happen, so you have to create a balance and go out and get some fresh air.
Yes. In between going out or doing something else. Clean up rooms or walk around the block. Occasionally ventilate.
An ergonomic workplace is also important. See "Ergonomics in the workplace" regular ventilation and movement do the rest. Get well
Yes, that can happen.
My school has therefore set a time limit of one hour for the video conferences, after which or before you have 30 minutes for preparation and follow-up work.
