If we use a computer for many hours (as people often do at work), there are some health issues that might affect us...
Eye-Strain
One health issue that can occur after using computers for a long time iseye-strain (tiredness of the eyes).
This is caused by looking at a monitor which is a constant distanceaway. The muscles that focus your eyes do not move, and so get tiredand painful. Eye-strain can also cause headaches.

This is caused by looking at a monitor which is a constant distanceaway. The muscles that focus your eyes do not move, and so get tiredand painful. Eye-strain can also cause headaches.
This problem can be solved:
- Look away from the monitor at regular intervals – re-focus on distant or close objects to exercise the muscles in the eye.
- Take regular breaks.
- Use an anti-glare filter in front of the monitor to cut down on screen reflections that can also tire the eyes.
Back and Neck Ache
Many people suffer from back and neck pain after working at a computer for a long time. This is usually due to them having a bad sitting posture.
This problem can be solved:
This problem can be solved:
- Use an adjustable, ergonomic chair, and take the time to set it up properly.
- The computer keyboard and monitor should be at the correct height for the seated person (keyboard lower than the elbow, top of monitor at eye level).
- Take regular breaks: get up, walk around, stretch your muscles
Bad Posture
Good Posture
The science of how we interact with the objects around us is calledergonomics.
An ergonomic chair is one that fits the body well, giving support to areas such as the lower back (lumbar region)

Repetitive Strain Injury (RSI) in Wrists and Hands
Any repetitive movement (same moovement over and over again) can result in a health problem called repetitive strain injury (RSI).
In particular, typing and using a mouse for long periods are common causes of RSI in the wrist (it is often called carpal-tunnel syndrome).
