Is 10 hours and 30 mins estimated screen time too much considering I’m having my online classes?

I was becoming way more unhealthy than I already was because I didn't have time to. I would spend the remaining 6 hours in the day (after taking out 8 to sleep) by taking breaks from the work, going to the bathroom, eating, and drinking water.

I had a world history course over a summer and it had me being online a minimum of 10 hours (at some points it was 14+) everyday for 5 weeks with only an occasional Saturday or Sunday off.

With that type of schedule my anxiety and stress went way up and I was becoming way more unhealthy than I already was because I didn't have time to. I would spend the remaining 6 hours in the day (after taking out 8 to sleep) by taking breaks from the work, going to the bathroom, eating, and drinking water.

And any extra time I had, I didn't have enough energy to do anything really. And this was only 5 weeks…i can't imagine doing a school uears worth.

So moral of the story is: If you don't want to be completely suffering DO NOT take classes that will have you online for 10+ hours.
