Your face is oily by mid-morning. You get breakouts that cluster around the jaw and hairline. There's a bitter taste in your mouth, particularly in the morning, and your breath isn't fresh no matter what you do.
Your stools are sticky and hard to pass cleanly. Your urine is dark. And you're irritable — not sad, irritable, with a short fuse and a sense of internal pressure.
This is Damp-Heat, one of the more uncomfortable constitutional patterns in TCM. It's what happens when dampness (the heavy, sticky residue of incomplete fluid processing) combines with heat (inflammation, agitation, overactivity). The two together are worse than either alone — heat makes dampness stickier, dampness traps the heat inside.
The nine signs
These are the features that most reliably distinguish this pattern. You don't need all of them — most people recognise four or five strongly.
01Oily face and acne
Particularly around the jaw, hairline, chest, or back. Skin feels greasy shortly after washing. May include boils or recurring spots.
02Bitter taste or bad breath
A distinct bitter taste, worst in the morning or after rich food. Often with a coated yellow tongue.
03Sticky, incomplete stools
Stool that's difficult to wipe clean, or that leaves a residue. Dark, strong-smelling urine.
04Irritability and impatience
A short fuse, a sense of internal pressure, and quick frustration. Heat agitates; dampness traps it.
05Heaviness combined with heat
The odd combination of feeling weighed down and feeling hot — limbs heavy, body warm, easily sweating.
06Red, dry, or irritated eyes
Especially in humid or polluted environments. Sometimes with a gritty sensation.
07Worse in hot, humid weather
Summer and rainy seasons are the hardest. Airless, humid rooms make everything worse.
08Strong body odour
Sweat that's noticeable and strong-smelling. A general sense of internal 'stuffiness.'
09Craving but not digesting rich food
You want fried, spicy, or heavy food, then feel worse after eating it. A frustrating loop.
How Western medicine sees it
Both frameworks describe something real. Knowing where they overlap — and where they don't — is what keeps you safe.
Acne vulgaris, seborrheic dermatitis, irritable bowel syndrome, non-alcoholic fatty liver, or a low-grade inflammatory state. Sometimes no diagnosis at all — just recurrent symptoms.
The Damp-Heat picture overlaps with low-grade systemic inflammation — the kind associated with metabolic dysfunction, poor diet, alcohol, and chronic stress. The overlap is real, even though the frameworks describe it differently.
Liver function (especially if alcohol intake is regular), fasting glucose, and inflammatory markers if symptoms are persistent. Recurrent skin infections should be assessed medically.
What's actually happening in TCM terms
Damp-Heat is a combination pattern, and that's what makes it stubborn. Dampness alone is heavy and slow; heat alone is dry and agitated. Together, the heat gets trapped inside the dampness — like steam in a closed room. You can't clear the heat without clearing the dampness, and you can't clear the dampness while the heat keeps cooking it.
The Dampness usually originates in the Spleen (poor conversion of food and fluids), and the Heat often involves the Liver and Stomach. This is why the pattern produces both digestive stickiness (stool, taste, coating) and emotional heat (irritability, impatience).
The critical treatment principle: clear heat and drain dampness together. Cooling alone doesn't work — it can actually worsen dampness (cold congeals). The traditional approach uses bitter-cooling and aromatic-drying foods and herbs in combination, not just 'cold' things.
What actually helps
Five practical directions. These are the levers that matter most for this pattern — not an exhaustive list.
Remove the heat-and-damp generators
Alcohol (especially beer), fried and grilled food, spicy food, excess sugar, and late-night eating. These are the highest-yield removals — most people notice a difference within two weeks.
Eat bitter-cooling and damp-draining foods
Mung bean, winter melon, cucumber, bitter melon, celery, lotus leaf tea, job's tears. Bitter flavour is specifically indicated for drying dampness and clearing heat.
Sweat regularly, then clean up immediately
Exercise that produces moderate sweating helps clear heat through the surface. But change clothes and shower promptly — leaving sweat on the skin in a hot climate worsens the pattern.
Keep sleep regular — heat builds at night
Late nights directly generate heat. For this pattern, consistent sleep timing matters as much as duration.
Avoid stuffy, humid environments
Air circulation matters. Air conditioning is fine for this pattern (unlike Yang Deficiency) — the problem is humidity and stillness, not cool air.

Common questions
Is this why my acne won't clear?
Possibly. Damp-Heat is a common pattern in persistent adult acne, especially around the jaw and hairline with oily skin. It doesn't replace dermatological treatment — but addressing the pattern often helps where topical approaches plateau.
Should I eat cooling foods like raw salads?
Careful. Raw and cold food can worsen dampness even while feeling 'cooling.' The traditional approach prefers cooked bitter and draining foods — bitter melon, winter melon, mung bean — over raw cold food.
Does coffee make it worse?
For many people, yes — coffee is warming and drying in a way that can aggravate heat. It varies individually. Green tea and lotus leaf tea are more traditionally appropriate.
How is this different from Phlegm-Dampness?
Phlegm-Dampness is heavy, cold, and foggy — no significant heat signs. Damp-Heat adds bitter taste, irritability, yellow coating, dark urine, and inflammatory skin symptoms. They're related but require different approaches.
