Ergonomics and Computers
Its amazing how many people use computers in the wrong way. Simple things like having your monitor sitting at the right height play a huge role in how comfortable you are, especially over the long period. For example, your monitor should sit with the top of the monitor at about eye level. Any lower or higher and you risk doing damage to your neck. So many people have the monitors lower, but if you think about when you stand normally the most comfortable position to look is straight forward, not bent down like that would promote.
Having the right height desk, chairs and back rest are also very important. Generally though I have found that it is your wrists and fingers that suffer first, before your back. To counter this, you need to ensure that you are working ergonomically. Get a mouse pad that is customized in a way that is comfortable. Your wrist pads should support not only the wrist and arm, but also the side of your hand that rests all of the time.
A good quality pad will make a world of difference, but you should still be taking regular breaks as well. Nothing is better than a short break every 30 minutes to stretch your fingers, shake your hands and look away from the screen. If you sit there for 8 hours every day glued to the screen then you will have issues later in life, especially if you use a computer at home as well. Look after yourself when you are using a computer and you wont ever have to research about RSI.
