Only if you don't use a keyboard the way it was intended. For example, Ctrl-c should involve both hands. If you press Ctrl-c with only your left hand (there's a reason your keyboard has a right Ctrl), you will gradually hurt your wrists. Emacs can accelerate this, since a lot of things begin with Ctrl-x, assuming that you never use the right side Ctrl.
I have never had carpal tunnel-like symptoms yet, though I just realised I've only used left ctrl for the past 10 years. I'll definitely be more mindful of that. Do you have any more resources on avoiding common typing pitfalls, or specific wrist movements one should avoid while typing? Should capitalising your sentences be a two-hand action as well, considering I normally only use left shift?
