Edit - This question may (understandably) invite knee-jerk reactions, so I'd like to clarify that I'm not talking about 70 hour work weeks. I'm talking about 40 hour work weeks plus 30 hours of leisure at the desk including weekends.
Lately I find myself having to pull myself away from the desk and wait for sleep to heal discomforts in my wrist and other areas. But almost everything I enjoy doing is tied intensely to being on the computer, like coding projects, research, and writing music. So I feel impatient and anxious not being able to do what I want to do.
I'm a software engineer by the way, so my endurance wears out cyclically, typically after a full day of work, a full evening of computer-based leisure, and second full day of work. Then the pain starts, which I can only imagine getting worse through my 30s.
Sure it's not natural, but consider it my life choice. I don't plan on having children anytime soon, so I have a lot of spare energy. What are the most impactful things to do in the short term to relieve the pain? What are the most impactful things to do to be able to keep doing what I like to do?
For the short term my thought was either (more) research into ergonomics or starting yoga. On the ergonomics front, a lot of things I've tried don't seem to help, so maybe I should hire a professional. I'm also reading a book on posture (no affiliation whatsoever). Yoga because I've heard it helps climbers strengthen their wrist, and because maybe stretching between meetings and regular intervals would help me, but I have no evidence for either. That's why I'm here asking.
For the long term I just have the idea to sleep better, eat better, and exercise. But it's vague and I want to know if there are more focused things I can do.
