A good friend of mine had carpal tunnel surgery in both hands (the doctor checked the other one just in case and went "eh, might as well do that one too") and one thing he was told to watch out for is to not have the wrists lay parallel to the desk for too long - so basically the default keyboard position. The reason is that in this position the bones in the arms are in a twist and that puts pressure on the tissues - most notably the nerves. Interestingly holding a gamepad or a phone in both hands is much closer to the ideal position. Personally I avoided most problems due to the fact that I've been playing the guitar since I was a teenager and this community is particularly interested in wrist and arm health, so I learned to watch out for early signs of strain and how to not overdo it early on.
