Ergonomics at the computer workplace

In short: A good workplace spares back, eyes and wrists. Screen at eye level, arms relaxed, regular breaks and movement.

In more detail: Long sitting and poor posture lead to tension and headaches. Small adjustments and breaks often help more than expensive furniture.

In Depth

• Screen: Top edge about at eye level, distance one arm’s length.
• Chair: Feet flat on the floor, knees about 90°, back supported.
• Keyboard and mouse: Forearms horizontal, wrists straight.
• 20-20-20 rule: Every 20 minutes look at something about 6 metres away for 20 seconds.
• Breaks: Stand up every hour, stretch, drink water.
• Light: No glare, no reflections on the screen.
• Laptop: External keyboard and mouse plus a stand for eye level.
