I actually had a similar reason for switching to das, a layout optimized for the finnish language. I was starting to get wrist pain while typing, started to take notice of my posture and switched to typing with das. Typing feels more natural and I can notice a huge difference to typing with qwerty (which I can still almost touch type). Again, I can't really say anything definite about the cause and effect but I can recommend giving a better keyboard layout a try.
