The Science Behind Proper Posture: A Comprehensive Guide

Poor posture while working at a computer can lead to various musculoskeletal disorders (MSDs), affecting millions of office workers worldwide. Recent studies have shown that workplace ergonomics can significantly impact both short-term comfort and long-term health outcomes.

Understanding Posture and Its Impact

Research published in the Journal of Occupational Health demonstrates that proper posture is essential for maintaining the natural alignment of your spine and supporting muscles. When sitting for extended periods, maintaining correct posture helps prevent:

• Chronic neck and shoulder pain (reported in 68% of office workers)
• Lower back strain and disc compression
• Carpal tunnel syndrome and repetitive strain injuries
• Decreased workplace productivity and increased healthcare costs

Evidence-Based Posture Recommendations

Based on recent ergonomic studies, the following guidelines have been proven effective:

• Monitor position: 15-20 degrees below horizontal eye level
• Keyboard placement: Elbows at 90-110 degrees
• Chair height: Knees at or slightly below hip level
• Regular movement: 5-minute break every 30 minutes
