• Adjust the ambient lighting around you (such as overhead lights, desk lamps, and the curtains or blinds on nearby windows) to minimize reflections and glare on the monitor screen. • Use a chair that provides good lower-back support. • Keep your forearms horizontal with your wrists in a neutral, comfortable position while using the keyboard or mouse. • Always leave space to rest your hands while using the keyboard or mouse. • Let your upper arms rest naturally on both sides. • Ensure that your feet are resting flat on the floor. • When sitting, make sure that the weight of your legs is on your feet and not on the front portion of your seat. Adjust your chair's height or use a footrest if necessary to maintain a proper posture. • Vary your work activities. Try to organize your work so that you do not have to sit and work for extended periods of time. Try to stand or get up and walk around at regular intervals. • Keep the area under your desk clear of obstructions and cables or power cords that may interfere with comfortable seating or present a potential trip hazard. monitor screen at or below eye level wrists relaxed and at monitor and keyboard positioned directly in front of the user feet at on the oor About Your Monitor | 31
