Healthy Sitting: A Complete Medical Guide to Proper Posture

Introduction
Modern life requires long hours of sitting—whether at work, study, or home. Because the average person spends a significant part of the day seated, maintaining a healthy sitting posture is essential. Poor posture places excessive stress on the body, especially the muscles, ligaments, and joints. In contrast, proper sitting posture helps the musculoskeletal system function efficiently and prevents unnecessary strain. This is especially important for people who spend long hours at desks or computer stations.

Why Healthy Sitting Matters

Adopting a correct and healthy sitting posture provides several crucial benefits:

1. Supports Bones and Joints

Maintaining proper alignment reduces pressure on joints and allows the muscles to work efficiently.

2. Prevents Muscle Strain

Correct posture decreases the risk of repetitive strain injuries caused by improper muscle use.

3. Reduces Pressure on Spinal Ligaments

Proper sitting posture minimizes stress on the ligaments that support the spine, which helps conserve energy and reduces fatigue.

4. Prevents Back and Muscle Pain

A neutral posture keeps the spine in its natural shape, reducing the likelihood of back pain, shoulder tension, and muscle discomfort.

Complications of Poor Sitting Posture

Sitting incorrectly for prolonged periods can lead to:

• Neck, shoulder, arm, back, thigh, and leg pain

• Reduced flexibility

• Limited joint mobility

• Breathing difficulties

• Persistent or chronic pain

• Numbness in fingers or wrist discomfort

• Eye strain (redness, dryness, headaches)

• Repetitive strain injuries

How to Sit Properly: Step-by-Step Guide

1. Adjust Your Chair

Ensure the chair height allows your keyboard to be used with straight wrists and arms parallel to the floor. This helps prevent strain injuries.

2. Position the Screen at Eye Level

Your monitor should be directly at eye height to avoid bending the neck.

3. Align Arms and Shoulders

Keep your arms parallel to the seat, with relaxed shoulders and elbows close to the body.

4. Support the Back

Sit upright, with the lower back supported. Use a lumbar pillow if available.

5. Adjust Knee Position

Leave a small gap between the back of your knees and the seat edge.

6. Keep Feet Flat on the Floor

Avoid crossing your legs. Keep both feet firmly supported on the floor or a footrest.

7. Distribute Weight Evenly

Your hips and thighs should share your body weight equally, with the torso kept upright.
