Is sensitivity related to kidney deficiency?
Generally, certain manifestations of sensitivity may be associated with kidney deficiency in traditional Chinese medicine (TCM), but not all sensitivity is caused by kidney deficiency. If concerned, it is advisable to consult a healthcare professional early. Detailed analysis is as follows:

In TCM theory, the kidneys are responsible for storing essence and governing reproduction. Deficiency of kidney essence may reduce the body's tolerance to external stimuli, leading to emotional sensitivity, anxiety, or increased sensitivity in the reproductive system. Such conditions are often accompanied by typical symptoms of kidney deficiency, such as soreness and weakness in the lower back and knees, dizziness, tinnitus, and fatigue, indicating a certain causal relationship.
However, sensitivity essentially reflects an excessive response of the body or emotions to external stimuli and may also be related to other constitutional imbalances, such as liver qi stagnation or deficiency of both the heart and spleen. For example, individuals with liver qi stagnation may experience emotional sensitivity and irritability, while those with heart-spleen deficiency may develop sensory hypersensitivity, insomnia, and vivid dreams. These conditions are not directly linked to kidney deficiency, and attempting to treat them solely as kidney deficiency is unlikely to bring improvement.
When sensitivity occurs, it is important to evaluate overall symptoms to determine whether kidney deficiency is involved, avoiding oversimplification. Emphasis should be placed on maintaining regular作息 (daily routines), managing emotional well-being, and seeking professional syndrome differentiation if symptoms persist. Targeted regulation based on individual patterns is essential for effective management.
