Which of the following is a symptom of Heat syndromes?

In Traditional Chinese Medicine (TCM), Heat syndromes are characterized by symptoms that indicate an excess of heat in the body. One of the hallmark symptoms of Heat conditions is a strong thirst for cold drinks. This thirst arises from the body's attempt to regulate and cool itself in response to internal heat. Patients often express a desire for coolness as a way to alleviate the discomfort associated with the heat, such as dryness and irritability.

Aversion to cold is typically associated with Cold syndromes, where the body feels chilled and seeks warmth. Fatigue and weakness are symptoms more aligned with Qi deficiency or Blood deficiency rather than an excess heat condition. Cold extremities often point towards Cold syndromes or Yang deficiency, where the body lacks warmth and energy.

Thus, the symptom of thirst for cold drinks aligns well with the defining characteristics of Heat syndromes in TCM, confirming it as the appropriate choice.
