Poor posture is a major contributing factor to the development of Repetitive Stress Injuries, as well as spending long periods without a break, sitting on an uncomfortable seat, at a poorly arranged workstation, etc. Doing your daily activities while assuming a bad posture will make your muscles shorten and become denser, which leads to a decrease in circulation to the misused area.
When poor posture is kept over a long period of time (months or years) it interferes with the natural movement of the body. The muscles which are affected in turn affect blood vessels and nerves. Once one has developed RSI, improving posture is a must in order to overcome the disorder.
You can reduce your risk of RSI by warming up and cooling down the muscles used, taking regular breaks throughout the day, having an appropriate workstation and seating position, and practicing relaxation.
