温熱 (on'net) refers to the concept of warmth or heat in traditional Japanese medicine. It emphasizes the importance of maintaining a balanced body temperature for overall health. Practitioners believe that warmth can help improve circulation, boost immunity, and promote relaxation. In various therapies, such as 温熱療法 (on'net ryōhō), heat is applied to specific areas of the body to alleviate pain and enhance healing. This approach is often used in conjunction with other treatments, like 鍼灸 (shinkyu), to create a holistic healing experience that supports both physical and mental well-being.
