Most mice that are used in offices today are not designed with human factors in mind. Some mice, like the Microsoft mouse, are designed to fit the contour of your hand. Although this may seem nice, it does not mean that one will be able to use it for hours on end and not feel any discomfort in the hand. Other mice, that will be mentioned later, are designed for comfortable use for extended periods of time. Try to keep your arms and hands warm.
Cold muscles are more apt to strain and injury than warm ones.
And finally, do not use the computer more than necessary. Your body can handle only so much strain on the neck, shoulders, wrists and fingers. Some people tend to use their break times at work playing video games. This is also a good example of using the computer 'more than necessary'. If a person needs to use a computer for video games, take a break every ten minutes or so, as mentioned above.ii All of these strategies mentioned above are things that can be done to reduce injuries when using a computer for an extended period of time.
