Initially, excessive indulgence generally does not damage kidney yin or kidney yang; it damages kidney essence. When kidney essence is impaired in a short period of time, some individuals may experience symptoms such as soreness and weakness in the waist and knees, premature graying of hair, and low energy. If these symptoms appear and one continues without restraint, indulging excessively, they may later develop symptoms like aversion to cold, cold hands and feet, frequent and urgent urination, and premature ejaculation with short duration, which are signs of kidney yang deficiency. In such cases, treatment should focus on warming and tonifying kidney yang.

However, not everyone will damage kidney yang. According to traditional Chinese medicine, kidney essence transforms into kidney qi, which is further divided into yin and yang. Sometimes, depletion of kidney essence can also damage kidney yin. Individuals in this condition do not experience aversion to cold or cold hands and feet. Instead, they may often feel chest tightness, irritability, and a sensation of heat throughout the body. Although they may have strong desires, they may struggle with issues such as short duration when it matters. For such cases, the primary focus of treatment should be on tonifying kidney yin.
