How can we reduce the negative impact of computer on the health & environment?
1.Health
What is ergonomics?
Ergonomics covers the design of the physical environment and equipment to maximize the quality of an employee's well-being. It covers everything from designing computers, computer desks, chairs and even lighting in a room.Take regular breaks, get regular eye exams and get a good desk and chair to maintain good posture.
Repetitive Strain Injury (RSI)
Often referred to as RSI. It is a condition caused by continuous use of keyboard or mouse. You should take regular breaks to help avoid such injuries. You may want to consider using a pad that you can rest your arms on, which will help somewhat.More information: http://www.rsi-center.com
Light problem while using computer
It is important that the right type of lightning is used in conjunction with your computer usage. Many find banks of overhead fluorescent, tube lighting a headache. Natural light is good, but there can be glare reflected from computer screens. Too much light can cause eye strain just like two dim lights. The direction of the light is also a consideration. If you are facing a bright light source while concentrating on your computer screen, it can cause eye strain.Screen and keyboard positions
When sitting at your computer you should have a monitor at eye level that can fit you. Additionally, you may want to consider a footrest. Neck pain and back pain can result from prolonged bad posture.Screen: Your screen should be fully fixed so that your eyes are at the same height as the top of the screen. You can use a filter attached to the screen to reduce glare. If the screen is poorly focused, too bright, or flickering, get a qualified technician to look at it. You should periodically refocus into the distance, as opposed to always looking at the screen a few inches from your eyes.
Keyboard: Use a good keyboard and you can use a wrist pad to reduce the stress on your wrists.
Mouse: Use a mouse mat to make using the mouse easier. Make sure you have enough space to use the mouse comfortably. If your arms or fingers become tired or painful while using the mouse, take a break and do something else.
Problems sitting while using the computer
If you spend a lot of time sitting at your desk using a computer, it's important to pay attention to the type of chair you're sitting on. Your chair should be fully adjustable and move up or down It should have a regular back. If your chair is not easily fixed it can lead to permanent back injury.
Health while using computer:
You should take regular breaks to avoid constantly looking at the screen and straining your eyes. During regular breaks, refocus your eyes between short and long distances as this can reduce eye strain.During your regular breaks, you may wish to practice some stretching exercises. These should be done only after doctor's advice to suit each individual.
You should use the best (ie most expensive) monitor that you or your company can afford. The better the monitor, the better the screen resolution and the higher the refresh rate. For detailed work, you should also consider using a larger screen size. In many countries, your employer has a legal obligation to pay for eye exams for employees when they request them. You can get filters that fit in front of the screen and reduce glare.
★ You can use a footpad to rest your feet while using the computer.
★ Make sure the area where you are using the computer has adequate lighting and good ventilation.
★ Ventilation is especially important if you use a laser printer, which can generate ozone during printing.
Make sure the cables are secured securely
You should always use the power cords supplied with your computer or cables of similar quality. Make sure cables are securely secured behind the desk and you have power points near the desk. If your desk has a cable ducting system, make sure you use it. Avoid long trailing wires as you or other people can easily trip over them and injure yourself or others In addition to personal injury, accidentally pulling a power cord can cause your computer to lose power and result in data loss. Network cables tend to be delicate and easily damaged, and the most common reason for failure to log into a network server is someone accidentally removing or damaging the network cables.Make sure PowerPoint is not overloaded
Overloading a power point is dangerous and a potential fire dangers. If you need more power sockets, have them properly setteled by a qualified electrician.2.Environment
Computer recycling options
★You should have a separate bin for paper that can be sent for recycling (make sure sensitive material is shredded first).★Printer toner cartridges can be sent for recycling; In fact some charities now collect spent toner cartridges and send them for recycling. You can also consider using recycled toner in your printers (but be aware that in some cases this may void the printer's warranty).
★Instead of dumping unwanted computer equipment, see if you can recycle them or even have them collected and used by a charity.
★Using on-screen manuals and help systems instead of printed manuals wherever possible will save on paper. This equates to cutting down fewer trees.
Computer energy saving options
★You may consider turning off computers and monitors when they are not in use.★Many monitors and other peripherals will automatically switch to 'sleep' mode after a period of inactivity. This means that the computer will consume less power even when it is still on.
