Multiple Postures on Office Chairs
There are mainly the following correct postures on office chairs:
The first is the standard office posture: Raise the computer screen to a position parallel to your line of sight. This prevents excessive forward or backward extension of the neck due to a screen that is too low or too high. Tilt your chin slightly upward to prevent lowering your head and extending your neck forward, reducing tension and fatigue in the neck muscles. Keep your chest slightly raised for smoother breathing and to help maintain good posture. Keep your waist naturally straight, using a bit of waist strength to maintain the normal physiological curvature of the spine and reduce pressure on the lumbar region. This posture is suitable for long hours of computer-based office work and can effectively prevent neck and back pain caused by poor posture.
The second is the posture of sitting on the edge of the chair: Adjust the chair height so that your knees and hips are at the same level, with your feet flat on the ground. This position allows the leg muscles to be in a naturally relaxed state, avoiding poor blood circulation due to the legs being suspended or overly bent. At the same time, keep your back straight to strengthen the back muscles and maintain spinal stability. This posture is suitable for short breaks or simple leg movements, such as moving your legs to promote blood circulation after sitting for a long time.
The third is the posture adjusted through small movements: Slowly twist your upper body to the right or left, place your hands on both sides of the chair back, inhale deeply while puffing out your abdomen, hold for 10 seconds, and then exhale slowly. This small movement can exercise the muscles in the waist and back, relieving muscle stiffness caused by maintaining the same posture for a long time. Taking such movement breaks at regular intervals during long hours of office work helps relax the body, improve work efficiency, and prevent physical discomfort caused by prolonged fixed postures.
