“汗” (hàn) is the Chinese word for "sweat." It is a clear, salty liquid produced by sweat glands in the skin. Sweating helps regulate body temperature by cooling the skin as the sweat evaporates. It is a natural response to heat, exercise, or stress. In traditional Chinese medicine, excessive sweating can indicate an imbalance in the body. Maintaining a healthy lifestyle, including proper hydration and nutrition, can help manage sweat production. Understanding the role of “汗” is important for overall health and well-being, especially during physical activities or hot weather.
