A lot of people keep their hands at the keyboard for long periods of time; excessive use of keyboard shortcuts keeps you in the same position for longer. I find that typing in bursts works better for me; I hold my chin, lean back, etc. while I ponder what to code next. Rather than keeping your wrist in the same position a lot, it gets to flex and move around. I had a lot more pain while coding at home because I would sit at the computer more often, but when working at an office, I have to get up and talk to people more often, and it really makes a difference. As for eye strain, getting a dark color layout for your code editor of choice and keeping most of your GUI dark helps. Black text on a white background is like staring into a lightbulb.
