By Akei Wong (Hong Kong) 文:王嘉琪(香港) In this digital age, we sit for long periods using our computers or mobile phones. The fatigue can cause us to develop bad sitting posture, bringing about conditions such as herniated vertebral disks, rounded shoulders, and cervical spondylosis. Herniated disks cause discomfort while sitting and pains in the lower back. Rounded shoulders lead to neck soreness, affect one’s appearance, and in serious cases, cause poor blood circulation to the brain, resulting in symptoms like dizziness and numbness in the arms. For good sitting posture, keep the waist and shoulders straight, forearms and thighs level with the chair and desk, calves vertically straight, and feet flat on the ground. The seat back cushion should conform to the curvature of the lumbar spine to provide sufficient support for the waist. Arm rests should be at an appropriate height to support the elbow, and ample seat area ensures even distribution of the weight of the body on the hips and the thighs. The Importance of Stretching If you sit for long periods regularly, relax the muscles and joints with stretching exercises. However, take note of your physical condition and avoid over-exertion. In case of any discomfort, stop the exercise immediately. Should the discomfort worsen or spread to other areas of the body, seek professional medical advice immediately. The spine supports the weight of the whole body. Injury can affect one’s general health, so take good care of it and sit up straight!
