True. Placing a support under your wrists (towel, or gel pad) so that you dont have to hold them up while you type will also help.

An "ergonomic" injury is one caused by the nature of your work. Strains in lifting things and industrial accidents would be examples. The most common "ergonomic" injuries these days are due to working with computers but remaining for too long in a position of poor posture or repetitive strain injuries. For example, excessive use of a mouse or keyboard can cause strains and discomfort in the hands and wrists. One classic example is "carpal tunnel syndrome". Carpal Tunnel Syndrome is caused by typing with your wrists bent UP. You can eliminate this risk by elevating the front edge of your keyboard, and typing with your wrists bent DOWN just a little. I'll warn you; if you do this, your typing speed will go to #@^%$# for the first week or two. But once you're accustomed to this, you'll get back up to speed and your wrists and hands will thank you.
