If my palms and soles feel hot but my tests are normal, could it be due to deficiency heat?

Why are test results normal even though my palms and soles feel burning?

The reason your palms and soles may feel burning even when test results are normal is likely because the heat you are experiencing is not 'inflammatory fever' caused by external bacteria or viruses, but rather a 'relative sensation of heat' caused by an internal energy imbalance.

General hospital tests check for inflammatory markers in the blood or absolute temperature measured by a thermometer. However, the heat we feel is often a subjective sensation that appears when the body's ability to regulate and distribute heat is declined, rather than simply because the temperature is high.

Why there is a difference between numerical values and actual sensation

Our body must always maintain a constant temperature and distribute heat evenly. However, if the ability to regulate heat is lost due to specific causes, heat may stagnate in certain areas or surge upward, even if the actual body temperature remains within the normal range.

This is similar to a situation where the total power supply is sufficient, but heat is generated because a specific wire is overloaded.

To understand this state, please look at the following differences.

• Inflammatory fever: Body temperature itself rises due to bacteria, viruses, or tissue damage, and is measurable by numerical values
• Relative sensation of heat (Deficiency heat): An increase in perceived temperature that occurs because the body cannot cool down due to a deficiency of internal fluids or declined function

Ultimately, saying that tests are normal means 'there is no acute inflammation or organic disease,' not that 'the heat you feel is fake.' You may be in a state of imbalance where the flow of heat is not smooth due to a functional decline in the body.

If the sensation of heat is accompanied by the following symptoms, it may be a signal of internal imbalance rather than a simple matter of temperature.

• The heat sensation in the hands and feet worsens as night falls.
• The mouth often feels dry, or the skin feels dry.
• Fatigue persists even after sufficient rest, and there is a feeling of tightness in the chest.

How are symptoms of heat rising to the face categorized?

Symptoms of heat rising to the face go beyond a simple feeling of being 'hot'; their nature varies depending on where the balance in the body has been disrupted. In Korean medicine, this is analyzed by subdividing the patterns of the heat axis, and it can be approached through three main categories.

Yin deficiency with internal heat (陰虛內熱): deficiency heat caused by fluid deficiency.

It may be a state where heat is not regulated relatively because the body's moisture and blood, namely, the jin-yeok (body fluids), have become deficient. This is similar to an engine overheating due to a lack of coolant.

In such cases A persistent, subtle heat sensation in the palms, soles, and face, which worsens at night or is accompanied by frequent dryness of the mouth and throatmay occur. This is more likely to be a pattern of 'deficiency heat' caused by a lack of body fluids, rather than an actual high fever.

Gi-heo-bal-yeol (Heat due to Qi Deficiency): Failure of regulation due to lack of energy

It may be a state where the Qi (energy) itself, which generates and transports energy, is deficient, leading to a decreased ability to regulate heat by sending it to the proper location or discharging it outward.

• You become short of breath and sweat easily even with slight movement.
• A heat sensation is accompanied by extreme fatigue.
• Due to a lack of energy to pull heat downward, heat may concentrate in the upper body.

Sang-yeol-ha-han (Upper Heat, Lower Cold): Imbalance between upper and lower body

This may be a typical state of imbalance where the upper body is hot and the lower body is cold. Rather than having too much heat itself, this is closer to a phenomenon where the circulation pathways of Qi and blood are blocked, causing heat to gather only at the top.

A contradictory situation occurs where heat rises to the face and head, causing redness or dry eyes, while the feet or lower abdomen feel chilly. a state where the core issue is 'imbalance of distribution' rather than the total amount of heatand because of this, heat in the palms and soles may appear simultaneously with coldness in the lower body.

How can you distinguish between simple heat sensation and deficiency heat?

It is very important to distinguish whether the heat sensation felt in the palms and soles is simply a 'state of having a lot of heat in the body' or 'fake heat caused by a lack of energy.' The key to distinguishing this is to examine the systemic symptoms that appear along with the pattern of heat.

First, excess heat (sil-yeol) refers to a state caused by the accumulation of actually excessive energy within the body. Like a boiling pot, the heat is strong and tends to appear systemically, usually accompanied by active metabolic reactions such as increased appetite or severe thirst.

On the other hand, deficiency heat (heo-yeol) is a state where heat rises relatively because energy is depleted. Rather than the actual temperature being high, as the body fluids or energy to cool the heat become insufficient, a pattern where specific areas feel burning or the heat sensation becomes prominentis observed.

Comparison of Excess Heat and Deficiency Heat Patterns

Category	Excess Heat (Energy Surplus)	Deficiency Heat (Energy Deficiency)
Range of Heat Sensation	Systemic feverish feeling, intense heat	Burning sensation in specific areas such as palms, soles, or face
Accompanying Symptoms	Strong inflammatory response, tendency for increased appetite	Accompanied by extreme fatigue and decreased vitality
Characteristics by time of day	Worsens during the day or during activity	Worsens at night or causes discomfort during sleep
Physical Response	Excessive sweating and facial flushing	Subtle heat sensation accompanied by dryness

In the case of deficiency heat, the sensation is often tolerable during the day but becomes more distinct at night when the body relaxes. This may be because the body's ability to regulate heat has declined due to a loss of internal balance.

Therefore, please use the following checklist to assess your current condition.

• Do you feel a sense of fatigue that does not go away even after sufficient rest?
• Is the heat sensation accompanied by dryness of the skin or mucous membranes?
• Do you lose sleep at night due to a burning sensation in your palms or soles?

If these items apply to you, it may be more appropriate to approach treatment from the perspective of restoring balance by replenishing depleted energy, rather than simply trying to lower the heat.

Do you experience heat in the soles of your feet that worsens every night?

Many people find the heat tolerable during the day, but suffer from burning soles that disrupt their sleep specifically at night. This temporal pattern helps determine the direction of medical evaluation, whether the heat you are experiencing is a simple rise in body temperature or deficiency heat caused by an internal imbalance.

Generally, deficiency heat is a phenomenon where heat becomes relatively prominent because energy is depleted. In particular, when the body's Yin component (陰分), namely, bodily fluids and moisture, becomes insufficient, the ability to cool the body decreases. During the night, when activity is low and the body relaxes, this imbalance can be felt more clearly.

The most characteristic point is seeking external cold stimuli to cool the heat sensation. If you feel temporary relief when soaking your feet in cold water or placing them on a cool floor, it may be a signal that your internal cooling system is not functioning properly and is seeking external help.

It is also necessary to observe your condition during sleep. If you notice slight sweating on the soles, palms, or chest during sleep, or if you feel your mouth is extremely dry upon waking, the possibility of deficiency heat due to a lack of bodily fluids is considered higher.

Please write these down before your visit

• Does the burning sensation in your soles worsen before bedtime compared to during the day, interfering with your ability to fall asleep?
• Does the heat subside only temporarily when you take a cold foot bath or apply a cool object?
• During sleep, on your hands, feet, or entire body Cold sweatssweating in your hands, feet, or across your entire body, or do you feel extreme thirst after waking up?

If several of the above items apply to you, this may be a pattern caused by a deficiency of Yin-blood (陰血) within the body rather than a simple increase in temperature. Keeping a detailed record of these patterns will help in more accurately understanding your current condition during a consultation.

What other bodily signals should be examined alongside the heat sensation?

Heat in the palms and soles is not just a problem localized to those areas, but can be a systemic signal from the body. Rather than focusing only on the local heat, observing changes occurring in other parts of the body can provide a clearer understanding of where your current vitality and energy balance stand.

The first thing to examine is the state of fluids and jin-yeok (vital fluids) in the body. A feeling of frequent dryness in the mouth or throat, and a sense that thirst is not easily relieved even after drinking waterIf these are accompanied, it is highly likely that this is not simple heat, but a state where jin-yeok, which acts as the body's coolant, has become deficient. When jin-yeok is lacking, the means to cool down the heat disappear, making the heat feel relatively stronger.

Additionally, please check for changes in overall energy efficiency and concentration. It is important to see if you feel fatigued easily even without strenuous activity, or if you experience a 'brain fog' sensation and a decrease in concentration. This can be one of the typical signs of deficiency heat (虛熱) that appears as the body's vital energy (正氣) is depleted.

Finally, you should check the state of your digestive organs and bowel movements. Check if you often feel bloated due to poor digestion, or if your stools are excessively hard and dry. Dryness in the intestinal environment is closely linked to a systemic deficiency of jin-yeok, which in turn can be a factor that exacerbates the heat in the hands and feet.

Please write these down before your visit

• Dry mouthDo you frequently experience dryness in the mouth and throat?
• Do you fatigue easily, and has your concentration during work or study decreased compared to before?
• Is your digestion poor, or do your stools tend to be hard and dry?

These accompanying symptoms serve as important indicators to distinguish whether the heat you are experiencing is a simple rise in temperature or deficiency heat linked to a systemic decline in vitality. If you record your condition in detail, a more precise evaluation will be possible during the subsequent consultation process.

Could there be other causes, such as thyroid disease or menopausal symptoms?

While heat in the palms and soles often appears due to deficiency heat caused by an internal energy imbalance, there are times when medical causes with entirely different mechanisms may be hidden. Rather than ruling out all possibilities just because test results are normal, it is necessary to keep the possibility of other diseases open and examine the patterns of the symptoms closely.

Influence of Hormones and the Endocrine System

The first thing to consider is rapid hormonal changes. Especially in women, menopausal symptoms occurring around menopause can decrease the regulatory ability of the autonomic nervous system, leading to sudden facial flushing accompanied by heat in the hands and feetThis is different from deficiency heat caused by a simple lack of jin-yeok; it is a phenomenon where the body's temperature regulation center reacts sensitively due to changes in hormone levels.

Additionally, endocrine disorders such as hyperthyroidism must be carefully examined. When thyroid hormones are secreted excessively, the body's basal metabolic rate increases sharply, leading to increased systemic heat and sweating. The heat felt at this time is not due to a relative lack of energy, but a state where the body actually becomes hot because metabolism is over-activatedwhich is more accurate.

Possibility of Abnormal Sensation in the Nervous System

If the heat appears only as a 'feeling' rather than an actual rise in temperature, peripheral neuropathy may be suspected. When peripheral nerves are damaged by diabetes, vitamin deficiency, or certain toxic substances, errors occur in the sensory signals transmitted to the brain. In this case, you may feel a burning or tingling sensation in the soles, which is not a problem of heat but abnormal sensation caused by abnormalities in the nerve transmission pathwayis highly likely.

If the following symptoms accompany a sensation of heat, a precise medical differential diagnosis may be necessary along with a Korean medicine approach.

• Sudden weight loss and increased heart rate
• Decreased sensation or numbness in the fingertips and toes
• Regularly recurring sensations of heat in the upper body and cold sweats

As shown, behind the same symptom of heat, different causes such as hormones, the endocrine system, or the nervous system may exist, in addition to deficiency heat. Therefore, it is important to determine whether the current condition is due to a simple lack of energy or a signal from a specific organ or the nervous system to establish an appropriate direction for response.

If symptoms recur, rather than deciding the cause on your own, please tell your provider during your medical evaluation when they worsen and what other symptoms appear together.

Will efforts to lower the sensation of heat in daily life be helpful?

When the palms of the hands or soles of the feet feel burning, the first method that comes to mind is likely soaking the feet in cold water or applying ice packs. In fact, cold foot baths or cooling therapies provide a temporary feeling of coolness and relief by immediately lowering the temperature of the skin surface.

However, these methods are merely 'temporary fixes' that briefly lower the surface temperature of the skin and do not resolve the fundamental cause of the heat sensation. Rather, if excessively cold stimulation is repeated, the body may produce more internal heat to respond or may worsen the imbalance in blood circulation.

The Proper Role of Lifestyle Correction

Correcting lifestyle habits, such as getting sufficient sleep, avoiding irritating foods, and managing stress, certainly has a positive effect. However, this should be understood not as the center of treatment, but as a supplementary meansway to increase the efficiency of the treatment.

• Cooling Therapy: Temporary symptom relief (short-term effect)
• Lifestyle Correction: Creating an environment for physical recovery (supportive role)
• Korean Medicine Treatment: Resolving internal imbalance and restoring the ability to regulate heat (fundamental approach)

Many people miss the timing for treatment because they expect symptoms to disappear completely through lifestyle changes alone. In particular, heat sensations caused by deficiency heat are not simply a 'hot state,' but a state where the body's jin-aek (essential fluids) are depleted, making it impossible to control the heat; therefore, there are clear limits to simply cooling the body from the outside.

Rather than relying solely on cooling therapy just because you feel hot, a process of examining internal imbalances is necessary when the heat sensation does not subside even with rest or when it leads to sleep disorders.

Ultimately, the important thing is not to extinguish the heat that appears on the surface, but to focus on why the heat is occurring. The key to improving symptoms is to create an environment where the body can manage heat on its own through a Korean medicine approach that replenishes deficient jin-aek and corrects the collapsed energy balance.

What mindset should I maintain to manage the sensation of heat?

Something that must be examined as carefully as physical deficiency heat is the heat of the mind, known as 'Sim-hwa' (heart-fire). Because our body and mind are closely connected, a persistent state of emotional tension can disrupt the balance of the autonomic nervous system and further amplify the sensation of heat in the hands and feet.

In particular, those with strong perfectionist tendencies or a heavy sense of responsibility often keep their bodies in a state of tension without realizing it. This psychological pressure causes heat to concentrate in the upper body and extremities, making the burning sensation feel stronger even when the actual body temperature is normal.

Difference Between Psychological Tension and Physical Heat Sensation

Please refer to the table below to see how your state of mind affects heat sensations.

Category	Psychological Tension (Aggravated)	Physical Energy Deficiency (Deficiency Heat)
Main Cause	Stress, anxiety, excessive preoccupation	Lack of bodily fluids, decreased vitality
Pattern of heat sensation	Surges suddenly or is accompanied by chest tightness	Persists subtly and worsens at night
Response Pattern	Aggravated when there are many thoughts or worries	More prominent during severe fatigue or on an empty stomach

The attitude to be most cautious of is becoming excessively preoccupied with the symptoms themselves. If questions like 'Why does it keep feeling hot?' or 'Why am I suffering when the test results are normal?' continue to spiral, the brain perceives this as a crisis and reacts more sensitively.

Therefore, we recommend caring for your daily life with the following mindset:

• Calm Acceptance: Rather than viewing the heat sensation as an 'enemy' to be eliminated, accept it calmly as a signal that your body and mind are currently exhausted.
• Intentional Relaxation: Release the tension of tightly wound nerves through short meditation or deep abdominal breathing.
• Redirecting Attention: Find emotional stability by diverting your focus from the heat sensation to the surrounding scenery or light hobby activities.

When the waves of the mind calm down, you may experience the heat in your body naturally subsiding as well.

Ultimately, emotional stability becomes an important foundation for managing deficiency heat. Letting go of urgency and allowing yourself to rest can be the first step toward regaining physical balance.

What should I record for myself before the consultation?

Before visiting the clinic for a consultation, the process of recording the symptoms you usually feel in detail is very important. This is because subjective heat sensations vary greatly from patient to patient, and a more specific evaluation is possible when the consultation is based on concrete records rather than relying on memory.

How to record your symptoms before your visit

1. Organizing symptom patterns: First, observe when, where, and how the heat sensation appears. Beyond a simple feeling of being 'hot,' please distinguish and organize whether it is a burning sensation, if it is accompanied by a tingling feeling, or if the skin surface is cold while heat is felt only internally.

2. Recording Specific Changes: Reflect on whether there have been any significant physical or psychological changes over the last 3 to 6 months. Recording sudden weight changes, fluctuations in sleep patterns, or extreme stress and emotional exhaustion will be very helpful in identifying the cause of energy imbalance.

3. Final Review and Submission of Records: Complete the symptom record based on the organized details. Especially if you are having a non-face-to-face consultation first or have a scheduled appointment, sharing your completed record in advance allows for a more efficient use of your medical evaluation time.

Core Checklist to Mention During Consultation

• The time of day when the feeling of heat is most intense: Record whether the symptoms are fine during the day and worsen only at night, or if they appear periodically at specific times.
• Specific Location and Pattern of Occurrence: Check in detail whether it affects the entire sole of the foot, is limited to the heel or the front part, or in the case of the palms, whether it is felt up to the fingertips.
• Presence of Accompanying Symptoms: Please also note if there are accompanying symptoms such as cold sweats, heart palpitations, or dry mouth along with the sensation of heat.

These records are not simply a list of symptoms, but serve as important indicators showing where the body's energy is currently leaking. If you have records based on careful self-observation, you will be able to find a clearer direction during the consultation process.

What is checked during the medical evaluation?

The core of the medical consultation is the process of finding the exact cause by connecting the 'subjective discomfort' felt by the patient with objective 'physical indicators.' Rather than simply the fact that there is heat, we focus on analyzing in detail where that heat starts and how it moves.

First, the specific location and nature of the sensation of heatis verified. We examine whether the entire sole of the foot feels burning, whether only a specific area is hot, and whether the heat stays on the surface of the skin or feels as if it is radiating from within. These subjective sensations help determine the direction of the medical evaluation by indicating how the energy inside the body has become imbalanced.

In the following process, the internal state is assessed through pulse diagnosis and tongue diagnosis, which are Korean medicine diagnostic methods.

• Pulse Diagnosis (脈診): The flow of Qi and Blood and the degree of deficiency or excess are estimated through the depth, speed, and strength of the pulse.
• Tongue Diagnosis (舌診): The color and shape of the tongue and the appearance of the tongue coating are examined to check for deficiency of bodily fluids or the degree of internal heat accumulation.

This process is intended to find subtle internal imbalances that do not appear in test results. Rather than simply suppressing symptoms, we analyze the fundamental reason why this sensation of heat occurred to set a direction for future improvement.

The consultation process is not just a time for making a diagnosis, but also a process for the patient to understand their own body's condition. By realizing the identity of the heat that felt vague and learning the principles of how to manage the body, patients can feel psychological relief and hope for improvement.

Points to Remember

The process concludes by clearly analyzing the current state of imbalance through the consultation and establishing a specific management direction tailored to the individual.
