The Tianzhu acupoint is an important point that can effectively relieve the neck and shoulder stiffness and stress headaches caused by prolonged use of electronic devices. Through precise location and a three-minute self-massage, it can relax neck muscles, improve blood circulation, reduce nerve compression, and enhance physical and mental comfort. Combining its massage with the Fengchi and Jianjing points can further enhance the soothing effect, improving shoulder and neck stress and mobility.
