Characteristics and causes of hyperhidrosis by body type
Although hyperhidrosis may appear to have the same symptoms, different constitutions tend to have different areas of sweating, different irritants, different patterns of heat and hot flashes, and different autonomic nervous system tension-recovery responses. Understanding the characteristics and causes of hyperhidrosis by constitution will help you interpret how your body is reacting in a three-dimensional way, rather than viewing hyperhidrosis, hyperhidrosis, generalized hyperhidrosis, and night sweats as simply “sweaty”. In this article, we’ve summarized the typical symptoms, aggravating factors, and autonomic response tendencies of hyperhidrosis as seen in the Sun-Yang, Moon-Sun, and Moon-Yin-Sun constitutions, centered on clinical observations.

ichthyophilic hyperhidrosis
It often manifests as hand and foot hyperhidrosis and is more pronounced in response to psychological stress, such as presentations, interpersonal tension, or unfamiliar surroundings, rather than temperature stimuli. Sympathetic nerves are rapidly fired, resulting in sweaty palms, sensitivity to caffeine, and tend to be accompanied by nervous sweating with trapezius and peri-neck muscle tension. Rather than “I’m sweating because I have a fever,” this pattern can be understood as an autonomic pattern in which tension and arousal are expressed as sweat.
Triggers of ichthyophilic hyperhidrosis
Hyperhidrosis is exacerbated by anxiety, social tension, intense stress, caffeine overdose, and sleep deprivation, and as stimuli are repeated, the sweat response tends to become conditioned and more easily triggered in certain situations.

Fetal Hyperhidrosis
Hyperhidrosis is characterized by sweating of the upper body (face, head, neck, chest, etc.), often manifested as head sweating, generalized hyperhidrosis, and generalized hyperhidrosis, and is characterized by heavy and viscous sweating with heat being directed upward. Symptoms are exacerbated in hot environments, enclosed spaces, and heated rooms, and are often associated with body characteristics such as body fat percentage, body shape heat distribution, and sweat gland activity. Hyperhidrosis, which is a tetrad, can be understood as a pattern of simultaneous increased hot flashes and sweating when body heat is retained in the upper body and poorly dissipated.
Common comorbidities in prenatal hyperhidrosis
In fetal hyperhidrosis, underarm odor, sticky intertriginous sweating, hot flashes, and increased heat sensitivity may be present, and discomfort tends to be associated with heat strain.

Noise-induced hyperhidrosis
Nocturnal hyperhidrosis is characterized by a combination of night sweats, weakness, and fatigue, even if the amount of sweating is not high, and is often exacerbated after overexertion, sleep deprivation, and stress. It is often best interpreted as “sweat as a sign of exhaustion” rather than “sweat as a sign of overheating” because the autonomic nervous system’s recovery axis is weakened as physical exertion increases and tends to be expressed as night sweats under stress.
Noise-induced hyperhidrosis checkpoint
Noise hyperhidrosis is characterized by feeling more tired after sweating, fluctuations in condition, and a strong association with fatigue and sleep, and should be considered alongside fitness and recovery status when interpreting symptoms.
No single factor is responsible for hyperhidrosis
Diathesis-specific hyperhidrosis is often a combination of constitutional tendencies, autonomic sensitivity, thermoregulatory rhythms, stressful environments, accumulated fatigue, and sleep and lifestyle habits. The same type of hyperhidrosis can manifest itself in different ways depending on your constitution, such as tension-responsive, upper body heat intensive, exhaustion-responsive, or emotional stimulus-responsive, and it is important to understand hyperhidrosis from the perspective of “how your body is sending you signals” rather than just how much you sweat. If your symptoms are persistent or interfere with your daily routine, it may be helpful to take a look at your current body chemistry, autonomic response patterns, and lifestyle to find a management plan that works for you.
