Core Viewpoint - The article discusses the correct sitting posture and debunks the myth that sitting with legs crossed is the healthiest position, emphasizing that maintaining the spine's alignment with the vertical plane is more crucial for spinal health [2][5]. Summary by Sections Correct Sitting Posture - The key to correct sitting posture is to keep the spine vertical relative to the horizontal plane, rather than focusing on whether the legs are crossed [5][11]. - A study involving 544 Greek physical therapists found that 97.5% preferred postures that align with the natural curves of the spine, particularly posture 2, which maintains a slight lumbar curve and aligns the pelvis, head, and shoulders [5]. Steps to Achieve Healthy Sitting Posture 1. **Find the Sit Bones**: Identify the sit bones to ensure even weight distribution while sitting [5]. 2. **Position of Hip and Knee Joints**: Maintain a 90-degree angle at the knees and hips, with feet flat on the ground [5]. 3. **Maintain Spinal Curvature**: Keep the natural curves of the spine by adjusting the upper body and screen position to avoid poor postures [6]. 4. **Alignment Check**: Ensure the head, shoulders, and hips are aligned vertically to alleviate tension in the shoulders and back [9]. Common Poor Sitting Postures - **Crossing Legs**: This can lead to pelvic tilt and uneven pressure on the lumbar spine, potentially causing spinal curvature issues and circulatory problems [11]. - **Hanging Waist**: This posture increases the load on the lumbar region and can lead to muscle strain and disc issues [12]. - **Leaning Forward**: This position can cause muscle tension and pain in the lower back due to prolonged contraction [13]. - **Reclining (Ge You Style)**: This comfortable position can lead to spinal imbalance and increase the risk of cervical and lumbar issues [14]. - **Overly Puffing Chest**: Excessive chest puffing can reduce the natural spinal curvature, leading to discomfort [15]. General Advice - Regardless of sitting posture, prolonged sitting is detrimental; it is recommended to stand and move for 5-10 minutes after every hour of sitting [17].
