- Take short breaks every 20 minutes. - Don't use keyboard on weekends (Your body needs time to recover) - Have a decent setup. Desk and chair height, arm rest position, keyboard and good size mouse. - Invest on a good keyboard. I use Kinesis-Advantage-2. You can also go extra miles with Dvorak. - Use vim key bindings. (You can use it on any editor even on your web-browser) - At least 15 mins daily exercise for your hands, neck, and shoulders. - Do physical activities to maintain muscle health. - Do sport but not too hard. For hangnails, use a normal hand cream every morning and every night before going to bed. The first few days is annoying to have greasy hands if you are not used to it. After some minutes it vaporizes or absorbs into the skin. It took me less than a month to get rid of hangnails. After that I only apply a little bit before going to sleep.
