The Fengmen acupoint is an important point on the back known as the "Gate of Defense," which helps to fend off wind-cold, soothe shoulder and neck pain, enhance immunity, and improve respiratory health. Through precise location and proper massage techniques, it can effectively relieve stress, improve blood circulation, and enhance mind-body balance. For daily self-care, one should pay attention to safety, avoid over-stimulation or application under unsuitable conditions, and integrate it into one's life to promote overall health.
