I have a sneaky suspicion that relaxing in this way and encouraging that mental wandering grants some sort of benefit, though I can't put my finger on what exactly. When I come home I'm always refreshed, and the next day often eager to get started on some idea I had while out and about. If I take a news feed with me, I miss out on this experience and, over time, seem to find myself drained of energy. Same if I compulsively check that feed the moment I get back home. A proper disconnect once in a while seems to work wonders. It's like... being constantly connected all the time is over stimulating somehow, without realizing it in the moment.

Rather just like we realized people need exercise, you just need to exercise the parts that you no longer need thanks to the internet.
Similarly, the internet has had a lot of externalities we may not have addressed.
