I'll add my own anecdote: I had an RSI "scare" about ten years ago while I was a student and similar things worked for me. I started to wear fingerless gloves or other things to keep my joints warm while typing and I took steps to reduce non-physical stress. I also took more breaks and made an effort to keep my hands aligned better. I did the latter two first and by themselves didn't notice any change but all together, my pain went away. Now I try to not type with cold hands when possible, try to keep my joints neutrally positioned and not type for too long at a time. I also used a mechanical keyboard for a long time (which requires very little pressure to activate the keys) and learned the Colemak keyboard layout. I haven't had any relapses although on busy days I can sometimes feel pressure building in my hands (I then take a break and do some stretches).
