Prevention of Computer Related Injuries

Following simple tips on exercise and ergonomics can prevent computer related injuries. It is easier to prevent computer related injuries than to cure them.

As with everything else, prevention is better than cure in computer- related injuries too. Faulty workplace habits left uncorrected can rapidly become serious problems. For example Repetitive Stress Injuries stemming from prolonged hours at the keyboard without pauses can seriously hamper work if they are neglected at an early stage. Wrist problems can compound into severe pain and swelling and a person cannot use a keyboard until the swelling goes away. In a worst case scenario the affected person may have to switch to a different kind of job altogether.

Risk for developing some of the RSI, such as Carpel Tunnel syndrome, may be inherent in an individual or may run in families. In such cases there is no single way to prevent the condition. The correct use of computers can go a long way to reduce related traumas.
