We spend a lot of time on the computer without knowing that is is seriously effecting our health, the most serious issues are repetitive stress injury (RSI) and eye strain. Repetitive strain injury (RSI) is an injury of the musculoskeletal and nervous systems that may be caused by repetitive tasks, vibrations, mechanical compression, or sustained or awkward positions. Since in the long term use of computer we are exposing our musculoskeletal and nervous systems to many repetitive tasks therefore we are prone to repetitive stress injury. There is a simple rule commonly known as 20- 20-20. By adopting this rule we can avoid computer caused RSI and eye strain. 20-20-20 rule suggest that after every 20 minutes, one must take a break for at least 20 seconds and look at objects which are 20 feet away. In this way your wrist and your eyes both will get some break. It seems to be a very simple rule to follow but in actual practice it is very difficult because when we are interacting with your friends on the social media like Facebook etc. These days most of us are internet savvy and social media edicts and we always forgot when the 20 minutes have passed. While writing a blog post we are tempted to finish it in one sitting. Similarly browsing the internet and other tasks on the computer have their own addition. Let us adopt this simple 20-20-20 rule from today to maintain a better health from now onward and avoid RSI. In my next posts I will discuss different forms of RSI which are known carpal tunnel syndrome and ulnar tunnel syndrome. I have personally suffered ulnar tunnel RSI which had severely affected my productivity on the computer.
