TCM attributes illness to what it calls the Seven Emotions: joy, anger, anxiety, pensiveness, grief, fear, and alarm. While these are all normal adaptive responses to the external environment, TCM holds that powerful emotional stimuli can create imbalances in yin-yang energy.
中醫有「七情致病論」的說法，認為喜、怒、憂、思、悲、恐、驚等 7 種情緒，雖是人類適應外在環境的正常反應，但劇烈的精神刺激，也可能導致體內陰陽氣血的失調。
