How is this different from body temperature?

Body temperature is a measured value, whereas cold-heat refers to the overall tendency of symptoms. You may feel hot even without an actual fever, or your hands and feet may be cold while your face feels hot.

What other factors are examined?

We examine the affected areas, timing, and changes such as sweating, thirst, digestion, sleep, and bowel movements. A diagnosis is not determined by cold-heat alone; necessary medical tests are checked first.

Can a person experience both cold and heat simultaneously?

Symptoms can be mixed; for example, the face and chest may feel flushed while the abdomen and feet are cold, or one may feel cold during the day but experience burning sensations in the palms and soles at night. These differences in distribution and timing serve as clues to distinguish mixed patterns, such as heat in the upper body and cold in the lower body.

Is cold-heat a fixed constitution?

Rather than a lifelong label, cold-heat is closer to a criterion for observing the current direction of symptoms. It can change depending on the season, sleep, stress, illnesses, and medications, so your current state is re-evaluated at the time of consultation.

Cold-heat is a criterion for observing the direction and combination of symptoms rather than body temperature

Cold-heat is a basic classification in Korean medicine that examines whether various signals, not just chills or heat sensations, but also thirst, sweating, skin color, digestion, urination, bowel movements, and sleep, cluster toward a cold or hot direction. Within one person, clues for cold and heat may conflict depending on the body part and time.

Commonly confused terms and their differences: Body temperature is a value measured at a specific site, while cold-heat is a result interpreted by combining medical interviews and physical examinations. Issues such as fever, hypothermia, thyroid, vascular, or neurological problems must be confirmed through medical diagnosis and testing; the term cold-heat does not replace these nor does it correspond one-to-one with low or high body temperature.
Information to record before your visit: Mark the cold and hot areas on the body diagram and record the timing of each symptom, body temperature, skin color, sweating, and thirst. By recording the relationship with meals, sleep, menstruation, and activity, as well as changes in bowel movements, urination, and medications on the same date, you can see how current symptoms move together rather than as a fixed constitution.
Scope of this material: WHO data was used for the standard terminology of cold-heat and pattern identification, and MedlinePlus data was used to distinguish between temperature regulation and the medical differential diagnosis process. This page is not a criterion for self-diagnosing cold-heat types or determining food and medicine. Persistent high fever, changes in consciousness, difficulty breathing, or abnormal blood flow on one side of the body require immediate medical evaluation over pattern identification.

Heat and Cold ColumnReasons for feeling hot: Korean medicine treatment for when you cannot tolerate heat despite a normal body temperature

If your body always feels hot and you sweat a lot despite a normal body temperature, we categorize issues related to the thyroid, menopause, medication, and recovery capacity, and examine Korean herbal medicine and acupuncture treatments tailored to heat sensitivity and accompanying symptoms.

Heat and Cold ColumnReasons why the body feels cold, and Korean medicine treatment when coldness in the hands, feet, and abdomen is accompanied by fatigue

This explains how to distinguish the reasons for a cold body from thyroid issues, anemia, and Raynaud's phenomenon, and describes how Korean herbal medicine and acupuncture treatments vary when coldness in the hands, feet, and abdomen is accompanied by poor digestion, fatigue, or edema.

Medical GuideWhere should I start checking when sensations of heat and cold recur?

Even if there are no clear abnormalities in tests, recurring sensations of heat and cold are a definite discomfort. By gathering information on the area, time of day, duration, and accompanying changes such as sleep, sweat, and digestion, we can examine the branches of symptoms more precisely from the perspective of heat and cold and determine the direction of Korean medicine treatment.

Comparison of similar terms
