Is it the same as having a fever?

Fever refers to a rise in body temperature, while a heat sensation is a feeling of warmth experienced by the patient. It is possible for a specific area to feel flushing even when the body temperature is normal.

How is it viewed if there are no abnormalities in the tests?

By examining the affected area, time of day, and patterns of change alongside sleep, sweat, thirst, and digestion, the direction of Korean medicine treatment can be determined from the perspective of heat-cold balance and pattern identification (Byeonjeung).

How is it different from a flushing sensation or a burning sensation?

A heat sensation is a broad term for symptoms of feeling hot. Flushing refers to a feeling of heat repeatedly surging up, while a burning sensation emphasizes a painful, searing sensation. If numbness and decreased sensation are present, nerve-related causes must be distinguished.

What kind of records are helpful in finding the cause?

Record the time body temperature was measured, the hot area, duration, skin redness and sweat, and the relationship with food, exercise, sleep, and menstruation. If there is swelling and redness on only one side or severe pain, inflammation and vascular issues are checked first.

Heat sensations are recorded separately by body temperature, skin changes, and feelings

A heat sensation is a symptom where the whole body or a specific area feels hot. An actual rise in body temperature (fever), local changes where the skin is red and warm, and a flushing sensation inside despite similar skin temperature are different phenomena; therefore, the cause is not determined by grouping them under one term.

Commonly confused terms and their differences: Heat intolerance is a systemic reaction where it is harder to endure hot environments than others, whereas a burning sensation is a sensation where searing pain or stinging is prominent. Heat syndrome is a category in Korean medicine that groups several symptoms, so it is not confirmed by a heat sensation alone; thyroid issues, menopause, medication, nerves, and skin causes are considered together.
Information to record before your visit: Record the area that feels hot, the start time, thermometer readings, skin color, sweat, and pain at the same time. Noting the indoor temperature, relationship with exercise, meals, menstruation, and sleep, changes in pulse and weight, numbness, decreased sensation, and new medications helps distinguish between fever, vascular reactions, and sensory changes.
Scope of this material: MedlinePlus data was used to explain the symptoms, medications, and necessary tests associated with heat sensitivity. A normal body temperature does not rule out all causes, nor is heat syndrome diagnosed based on a heat sensation alone. You must seek medical attention immediately if there are changes in consciousness, difficulty breathing, persistent high fever, one-sided paralysis, or an area that swells and reddens rapidly.

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 ColumnMy face feels hot; the cause varies depending on redness, sweating, and palpitations

When the face feels hot, we distinguish between actual skin temperature and the sensation of burning, and provide guidance on the causes and directions for Korean herbal medicine treatment based on redness, sweating, palpitations, and coldness in the hands and feet.

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 GuideHow do I distinguish between different types of heat and burning sensations in the soles of the feet or palms of the hands?

Heat in the palms and soles may be centered on a burning sensation rather than actual skin temperature. We first distinguish whether there is numbness or decreased sensation; if the cause is not clear from tests, we determine the direction of Korean medicine treatment by examining whether it worsens at night and its relation to sleep, dry mouth, 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 ConceptThermoregulation

Temperature regulation is a process where the brain, autonomic nervous system, blood vessels, sweat, and metabolism work together to produce and release heat. If your face feels hot while your feet and lower abdomen feel cold, it is easier to identify the cause and determine the direction of medical evaluation if you record the thermometer readings separately from the affected areas and times.

Korean Medicine ConceptHan-yeol

Cold-Heat (Han-yeol) is a criterion for dividing the body's current tendency by looking not only at feelings of cold or heat, but also accompanying patterns such as thirst, sweating, digestion, and sleep. It does not mean the same thing as a single thermometer reading.
