《黄帝内经·灵枢·百病始生》
岐伯答道：忧愁思虑过度，则损伤心脏；在寒饮寒食的基础上又感受风寒之邪，双重的寒邪损伤肺脏；忿恨恼怒过度，则损伤肝脏；酒醉后行房事，或汗出后受风，则损伤脾脏；劳累过度，或行房事而大汗淋漓后洗浴，就容易损伤肾脏，上述就是内外三部发生疾病的一般规律。
岐伯曰：忧思，伤心；重寒，伤肺；忿怒，伤肝；醉以入房，汗出当风，伤脾；用力过度，若入房汗出浴水，则伤肾，此内外三部之所生病者也。
Qi Bo replied: Excessive worry and contemplation can damage the heart. Getting wind and cold after getting cold and damp can cause the cold to damage the lungs. Excessive annoyance and anger can damage the liver. Having sex when drunk or getting wind after sweating can damage the spleen. Overwork or bathing after sweating from sex can easily damage the kidneys. These are the general principles of the occurrence of diseases in the internal and external three parts.
