I would argue it certainly does — heat/cold is comfort vs injury. Pressure is massage vs. crush injury. Trauma, I suppose, is definitionally bad. Repetitive motion is muscle mass and strength increase vs RSI. Exertion is cardiovascular health vs exhaustion. Posture, I'll give you — I don't think there's such a thing as posture that is /too/ good as long as you're staying mobile/stretching/taking breaks. Perhaps a more intuitive way of stating it is, "Some classically bad things can be good in small or optimized doses. Some classically good things can be bad when taken to excess."
