Posture Issues
Your posture while working could have significant health effect according to Australian medical researchers. The time that you spent while holding your hands over the keyboard, but without typing, can post a health problem. ‘We refer to this position as the “action ready” posture when the forearm(s) is in full probation over the keyboard or mouse causing muscle activation of the forearm extensor muscles,’ the researchers wrote.
The Australian medical researcher further explained: ‘This may lead to the development of painful trigger points in the forearm extensor muscles, a common area of complaints by computer users. Activities such as reading, talking, thinking, etc. while using the computer are frequently accompanied by this “action ready” posture.’
Other risks caused by this wrong posture include likelihood of injuries to the neck and shoulder area as a result of muscle overuse. It is because neck and shoulder muscles are put into activity when the use of PC mouse is with the arm and extended away from the body. This occurs when the monitor is very far thus pushing the chin juts forward or when the keyboard is too high while the shoulders are held at hiked positions. Keeping this posture proved detrimental to the upper extremities of the body (with or without keystrokes and mouse clicks).
To counter this problem, there are some suggestions to reduce the risk of muscle and joint problems including:
Eye Strain
Our eyes are structurally endowed to look at objects further than six metres away. So any work performed at close proximity puts extra pressure on eye muscles. Fatigue can result if you focus your gaze at the same distance point for long periods.
The illumination coming off from the PC monitor causes eye fatigue. Users of PCs may experience symptoms like blurriness and acute inability to focus on faraway objects. Not to mention headaches.
Here are some tips to reduce the risk of eyestrain:
