Health & Safety
A number of health problems have been associated with the use of computers, especially if they are used a great deal. Some of the worries have since been disproved, while others can be managed. The following medical problems have been linked to using computers.
- RSI - Repetitive Strain Injury
- Eye Strain
- ELF radiation
- Back Problems
Repetitive Strain Injury is a disorder caused by repeating the same actions over and over again. This is often caused by typing. It leads to tight muscles in the forearms and can even lead to pain in the nerves of the fingers making it difficult to use them.
There are a number of things which can be done to reduce the risk of RSI. Correct posture and supporting the arms using a wrist mat when resting the arms will help reduce RSI. Touching lightly on the keys instead of punching them. Changing task every so often also helps as you probably will not be using the same movements. Keep the mouse close to the keyboard where it is handy. Better still learn the keyboard short cuts and use them instead. Using macros to replay multiple keystrokes is also a benefit. Voice recognition software may also be used to reduce typing and so reduce RSI.
Although there is no evidence to suggest the using a VDU (visual display unit - monitor) damages the eyes, but sitting in front of a computer screen for long periods of time can lead to tired eyes. Making sure…
