Six Excesses: When the Weather Attacks

🔊English already has a phrase that captures part of what Chinese medicine calls the "six excesses": "catching a chill." Most English speakers use this loosely, without really believing that cold weather itself causes illness rather than the germs that happen to spread more easily in it. Chinese medicine takes the idea more literally and more systematically, describing six environmental patterns — wind, cold, heat, dampness, dryness, and fire — as external factors capable of invading the body directly and causing a recognizable pattern of illness.

🔊Each of the six has its own signature. Cold tends to cause contraction, stiffness, and pain that eases with warmth. Dampness tends to cause heaviness, sluggishness, and symptoms that are slow to resolve, the way damp air itself feels heavy and lingers. Heat and fire tend to cause redness, rapid onset, and a feeling of being overheated from within. Dryness tends to cause thirst and irritation of anything moist by nature, such as the throat or skin. Wind — discussed more in the next lesson — tends to cause sudden changes and symptoms that move from place to place.

🔊The word "excess" in "six excesses" doesn't mean these six things are bad in normal amounts — a cold breeze or a humid day is simply weather. They become "excesses" specifically when a person's body is not equipped to handle the exposure, which is why the same weather can leave one person unaffected and another person clearly unwell. It's less a claim about the weather itself and more a claim about the meeting point between weather and a particular body's current resilience.
