PAINS AND ACHES
1) Headache
Besides eyestrain, long hours in front of a VDT can also lead to headaches. Rest breaks are important as a means of prevention, and some experts recommend that you wear some type of tinted glasses to reduce the risk of headache from staring at a bright VDT screen.
2) Neck Pain
Many people who work with a VDT all day end up with neck spasms and muscle fatigue. That’s usually because the terminal is positioned in such a way that these people have to look up or down all day. Experts recommend that you position your VDT at eye level to avoid the discomfort of neck pain. The height of your desk should also enable you to sit at your keyboard so that your lower arms form a 70 to 90 degree angle to your upper body. The monitor itself should be within a 30 degree viewing angle of your direct line of vision.
3) Backache
Poor posture while working long hours at a computer can contribute to backache. To avoid this problem, you should adjust your chair to suit your height at the desk and to provide adequate support for your lower back. The height of your chair should allow you to sit in a relaxed position with your feet firmly on the floor and your back straight.
