Excessive sweating during sleep at night refers to night sweats. Under normal circumstances, night sweats may occur in individuals with kidney yin deficiency.

Kidney yin deficiency is a constitutional condition in traditional Chinese medicine, primarily characterized by insufficient body yin fluids, resulting in weakened nourishing and moisturizing functions. In such cases, the balance between yin and yang in the body is disrupted, with relatively excessive yang energy that is not effectively restrained by yin fluids. Consequently, during nighttime rest, the overactive yang energy causes excessive perspiration, leading to night sweats.

In addition to night sweats, individuals with kidney yin deficiency may also experience a range of other symptoms, such as soreness and weakness in the lower back and knees, dizziness, tinnitus, insomnia, and vivid dreams. It is recommended that patients seek timely medical attention and follow medical advice for treatment with medications that nourish kidney yin. Additionally, patients can appropriately consume foods that have functions of nourishing yin and benefiting the kidneys, such as black beans, black sesame seeds, and yam, to help improve the condition of kidney yin deficiency.

In daily life, it is also advisable to maintain healthy lifestyle habits, such as regular sleep patterns, moderate exercise, and balanced diet, which can help improve the condition of kidney yin deficiency.
