Most people know one thing the Lung does.
It moves air. Oxygen in, carbon dioxide out. That's the one. That's the whole story for most people.
But in Traditional Chinese Medicine, the Lung has four jobs. And three of them have nothing to do with breathing.
The first is the one you know. The Lung governs respiration. Every inhale brings oxygen to your cells. Every exhale releases waste. That part isn't new.
The second is your immune layer. In Chinese medicine, the Lung produces something called Wei Qi. It's the defensive force that circulates at the surface of your body. Think of it as your outermost shield. When the Lung is strong, the Wei Qi is strong. When the Lung is struggling, drafts and bugs and viruses find their way through more easily. If you catch every cold going around, this is worth knowing.
The third is your skin. The Lung governs the skin. Chronic eczema, rashes that shift but never fully clear, dryness that no moisturizer seems to fix... those can all be the Lung showing itself on the outside. The organ and the surface are one system.
The fourth is grief. Not as a metaphor. As physiology. When loss isn't processed, when grief doesn't have anywhere to go, the Lung is where it tends to settle. The body doesn't know about the five stages. It just keeps the door open until the weight gets addressed.
The Lung also has a primary direction: downward. Descent. Release. When we breathe shallow, which most of us do when we're carrying something, the Lung can't complete its own motion. It gets stuck halfway through a job it was designed to finish.
Last week, we talked about the Earth element and the Spleen. The Spleen feeds the Lung. Earth generates Metal. When digestion is depleted, the Lung is often the next system to feel it.
Two points worth knowing if you want to support the Lung at home:
LU9: on the wrist crease, in the depression at the base of your thumb. Press firmly for 2 minutes on each side. This is the source point of the Lung channel. It's the deepest nourishment point the meridian has.
LU1 and SP20: on the front of the chest, just below the collarbone. Press firmly. If one side is tender in a way you weren't expecting, that's infor
