Han-jeung (Cold Syndrome)

Related terms: Cold tendency, 寒證

Cold syndrome (Han-jeung) refers to a tendency where various body signals lean toward a cold state. It is not a term used to describe diseases such as anemia, hypothyroidism, or vascular and nerve problems.

Is it simply a matter of having a constitution that is sensitive to cold?

Cold Syndrome is not diagnosed based on cold sensitivity alone. We examine the specific areas that feel cold, digestion, fatigue, changes in skin color, menstruation, current medications, and test results.

Which distinction comes first?

Since systemic coldness can be related to anemia or thyroid issues, skin color changes in the hands and feet to Raynaud's phenomenon, and numbness to peripheral nerve issues, necessary medical tests take priority.

Is it the same as Yang Deficiency (Yang-heo)?

Cold Syndrome refers to a general trend of symptoms leaning toward coldness, while Yang Deficiency is a more specific category describing a lack of function to warm and move the body. Not everyone with Cold Syndrome is viewed as having Yang Deficiency.

What questions are asked during the medical evaluation?

We check the affected cold areas and timing, changes when warmed, thirst, sweating, digestion, bowel movements, urination, fatigue, and sleep. These clues are reviewed alongside existing test results to determine the actual direction of treatment.

Cold Syndrome (Han-jeung) is determined not by a single feeling of coldness, but by observing a cluster of accompanying symptoms.

Cold Syndrome describes a pattern where cold sensitivity, coldness in the hands, feet, or abdomen, and clues such as skin color, digestion, bowel movements, urination, and fatigue all align toward a 'cold' direction, including how the body responds to warmth. It is not determined by a simple preference for avoiding cold or a temporary seasonal reaction.

Commonly confused terms and their differences
Cold hands and feet and the sensation of cold are symptoms felt by the patient, whereas Cold Syndrome is a category of pattern identification (Byeon-jeung) that groups various pieces of information. Yang Deficiency specifically describes clues of functional decline and difficulty maintaining warmth within Cold Syndrome, and is distinct from anemia, hypothyroidism, Raynaud's, or nerve issues.
Information to record before your visit
Please note the areas and times you feel cold, the ambient temperature, the recovery time and skin color after warming. Also record your appetite, bloating, bowel movements, urination, menstruation, fatigue, weight changes, numbness, and any medications you are taking. If you have blood test or thyroid test results, please prepare the dates and values.
Scope of this material
WHO data was used to define the traditional medicine scope of Cold Syndrome and Yang Deficiency, and MedlinePlus data was used to distinguish the medical causes of cold sensitivity and Raynaud's phenomenon. This explanation of Cold Syndrome does not diagnose a disease or guarantee the efficacy of warming treatments or Korean herbal medicine. Sudden color changes, severe pain, or wounds in one hand or foot must be evaluated immediately.
