How is it different from deficiency heat?

Excess heat refers to a pattern where the momentum of heat is distinct, whereas deficiency heat refers to heat that arises when the body's fundamental essence is lacking. In actual clinical practice, these are distinguished by the overall condition rather than a single symptom.

Is it the same as having a fever?

No. A fever is a rise in body temperature, while excess heat is a pattern identification in Korean medicine. Sudden high fever requires checking for causes such as infection first.

What is evaluated during the medical consultation?

We check body temperature, the location and intensity of the heat sensation, thirst, sweat, skin color, changes in bowel and bladder movements, and sleep.

Can I just keep everything cold in my daily life?

If you excessively cool your entire body based solely on the term 'excess heat,' you may miss the distribution of symptoms. You must confirm actual fever and inflammation, observe which areas are hot and when, and then determine the appropriate response.

Excess heat is not determined solely by the feeling of intense heat.

In Korean medicine, excess heat describes a pattern where clues of heat appear strongly together, such as a distinct heat sensation, thirst, facial flushing, sweating, and constipation. It is not determined simply by the intensity of symptoms, but by considering physical strength, sleep, digestion, and clinical examination findings.

Commonly confused terms and their differences: A fever is a medical sign of increased body temperature, and inflammation is a biological response confirmed through tests and examination. The pattern identification term 'excess heat' is not the same as either of these. The distinction from deficiency heat is also judged by the overall relationship, including dryness, fatigue, and nighttime patterns, rather than just the intensity of the heat sensation.
Information to record before your visit: Please record the temperature and time measured with the same thermometer, as well as the area of heat sensation, skin color, thirst, and sweat. Recording bowel movements, urination, sleep, relationship with food/alcohol/exercise, chills, cough, pain, rash, and any new medications will help in examining actual fever, lifestyle triggers, and pattern identification clues.
Scope of this material: WHO data was used for the scope of traditional medicine terms for excess and deficiency heat, and MedlinePlus data was used to distinguish medical causes and emergency signals of fever. This page is not a standard for diagnosing excess heat or determining methods and medications to cool the body. High fever accompanied by changes in consciousness, difficulty breathing, neck stiffness, convulsions, or severe dehydration requires immediate medical evaluation.

Heat and Cold ColumnReasons for heat in the feet: Why do they feel burning when test results are normal?

We examine the causes of heat sensations rising to the soles of the feet, palms, and face from a Korean medicine perspective when hospital tests show no particular abnormalities, and provide criteria for self-assessment.

Heat and Cold ColumnBurning soles: Why do they feel hot when tests are normal?

When heat sensations in the soles persist despite no particular abnormalities found in tests, we explain the meaning of the test results, symptoms to re-verify, and what is examined in Korean medicine treatment.

Heat and Cold ColumnReasons for hot hands and feet: Why is there a heat sensation when test results are normal?

We examine the causes of burning sensations and heat felt in the palms and soles, even when hospital tests show no abnormalities, from the perspective of 'heat' (熱) in Korean medicine, and provide criteria for self-checking your condition.

Medical GuideWhat else should I examine when my face feels hot or heat rises to my face?

Facial heat sensations can be divided into facial flushing where redness is visible, upper body heat where only heat is felt, and patterns where sweating and palpitations occur together. Even if there are no abnormalities in tests, sharing the time of occurrence and accompanying symptoms can help find a more specific direction for Korean medicine treatment.

Medical GuideWhat should be checked when the entire body feels excessively hot or cold?

Sensitivity to heat or cold throughout the body can be caused by various factors, including the thyroid, medication, anemia, and menopause. If discomfort persists despite no major abnormalities in tests, we can determine the direction of Korean medicine treatment by analyzing systemic heat/cold tendencies along with sleep, digestion, sweat, and fatigue.

Comparison of similar terms

Korean Medicine ConceptHeat syndrome

Heat syndrome refers to a tendency where various body signals converge toward a 'hot' direction. It is not a disease name referring to fever caused by infection or thyroid disease, so necessary differential diagnosis is required first.

Korean Medicine ConceptHeo-yeol

Deficiency heat (Heoyeol) does not mean having a 'heat-prone constitution'; rather, it describes a pattern where heat sensations appear alongside fatigue, changes in sleep, and dry mouth. You should not confirm this diagnosis on your own based on symptoms alone.

Symptom ExpressionFeeling of heat

A feeling of heat is a symptom where you feel warmth in areas such as the face, chest, palms, or soles, regardless of the reading on a thermometer. The affected area, timing, and accompanying changes, such as redness, sweating, or numbness, serve as clues to categorize the cause.

Medical TerminologyCold-Heat Pattern Identification

Pattern identification (Byeon-jeung) is the process of examining the location and timing of heat or cold sensations, as well as accompanying patterns such as sleep, digestion, and sweating, through medical interviews and physical examinations. It is not a substitute for medical tests or diagnoses.
