This guide introduces a method for relieving stress and improving sleep through foot reflexology, emphasizing the connection between specific zones on the sole of the foot and the nervous system. It describes in detail the method for locating the reflex zones and a three-step massage technique, including the thumb-walking method, the stationary deep pressing method, and the neck/spine pinch-and-pull method. It also explains how this process activates the vagus nerve to reduce stress hormones and promote serotonin secretion, thereby improving sleep quality, alleviating anxiety, and enhancing brain health.
