Here is a news flash, Wrist Pads and Gel Pads are not proven to prevent Carpal Tunnel Syndrome (CTS). In fact, they may actually make matters worse. To understand this better, one needs to know what Carpal Tunnel Syndrome is. Since I like to get right to the point, I will explain it in one sentence. Carpal Tunnel Syndrome is when constant pressure and repetitive movements or stresses cause the "tunnel" of bones and ligaments in your wrists to narrow, which pinch the nerves that pass through the "tunnel". This pinching of nerves can cause numbness, pain, and damage to your hand.
The carpal tunnel in your wrist is actually quite tight. There is very little room for anything but the tendons and nerves that pass through it, so any additional pressure, from say, a wrist pad for your mouse, will increase the chance that the median nerve in your hand gets pinched and irritated. Repetitive movements and stresses could cause your tendons to swell, which would just make matters worse.
Tips to Prevent Carpal Tunnel Syndrome (CTS)
1. Try not to rest your wrists directly on any surface while typing or using a mouse
2. Take frequent breaks when doing anything repetitive, like working on the computer, typing, playing video games, etc.
3. Try to find a sitting position with your elbows at your sides, and your keyboard straight out, level with your elbows.
4. If you MUST use a wrist pad, do not press into it or put weight on your hand. In fact, try not to touch it at all.

One of the fundamental ways to prevent Carpal Tunnel Syndrome is actually to make sure your computer desk has an elbow-level keyboard tray. The tray should be low enough so that you can adjust your seat height to form a 90 degree angle at your elbows. In this position, you will be able to sit and work longer, with improved comfort. No wrist pad required.
Unfortunately, the Wrist Pad myth is everywhere. If you do a quick search on the Internet, you will find a lot of people peddling Wrist Pads and Gel Pads as something that can improve comfort, relieve stresses, and prevent Carpal Tunnel Syndrome. Do not believe it. Your wrists will thank you!
