Health experts have issued new guidelines in an attempt to reduce the number of injuries suffered each year by computer users.
Poorly arranged keyboards and monitors are blamed for causing repetitive strain injury (RSI) which can result in crippling pains in a sufferer's hands and arms as well as pains in the back and chest.
Government watchdog the Health and Safety Executive (HSE) said RSI causes misery for 400,000 people in the UK each year. The knock-on effect for business is a loss of four million working days a year.
Factors such as posture and repetition of tasks can increase the risk of RSI and how long it lasts.
The HSE's two new booklets to counter RSI-related problems tell users how to cut their risk and inform businesses of their responsibilities.
"By following the guidance, preventative action can been taken quite easily and need not be costly," said Owen Tudor, HSE commissioner.
The guides were produced in response to a tightening of health and safety laws last year, and are available from the HSE and bookstores for £8.95.
