Is kidney deficiency caused by masturbation categorized as yang deficiency or yin deficiency?
Generally, kidney deficiency caused by masturbation may manifest as either kidney yang deficiency or kidney yin deficiency, and the specific type should be determined based on symptoms. The analysis is as follows:

When masturbation leads to kidney yang deficiency, individuals often experience cold intolerance, particularly noticeable in cold hands and feet. Other possible symptoms include low energy, pale complexion, soreness and weakness in the lower back and knees that worsens with cold exposure, increased nighttime urination, and loose stools. This occurs because excessive activity depletes the body's yang energy, resulting in insufficient kidney yang that fails to warm and nourish internal organs and tissues, thereby triggering a series of deficiency-cold symptoms.
When masturbation leads to kidney yin deficiency, common manifestations include tidal fever, night sweats (excessive sweating during sleep that stops upon waking), dry mouth and throat, heat sensations in the palms and soles, insomnia with vivid dreams, and soreness or weakness in the lower back and knees. This primarily results from excessive depletion of the body's yin fluids, leading to insufficient kidney yin that fails to moisten and nourish the organs. At the same time, deficient fire (false heat) arises internally, causing various deficiency-heat symptoms.
Once symptoms of kidney deficiency appear, it is important to promptly adjust lifestyle habits to avoid further depletion. During recovery, one should differentiate between yang deficiency and yin deficiency based on individual symptoms and avoid blind supplementation. If symptoms persist or worsen, professional medical help should be sought. Scientific approaches to调理 (regulation), along with maintaining regular作息 (daily routines) and a balanced diet, will support the body’s recovery.
