I'm not sure how talking to coworkers, going for a walk or cleaning your desk could be classified as problem solving but I admit everyone sees things differently. I feel quite relaxed while reading online technical articles, it feels to me nothing like problem solving. If it does cause you stress or mental fatigue then please consider another activity.

The real point is there are many things one can do while in the office that can provide distraction from mental stress while still being valuable. I would argue against a definition of "problem solving" as literally anything that happens while within the walls of an office.
