QiLifeQi Deficiency 气虚
Qi deficiency means your defensive and transformative Qi runs low, so ordinary effort costs more than it should and colds come easily.
Pinyin: Qi Xu · updated
Qi is not a substance you can hold; it is the body's capacity to move, warm and defend itself. When Qi is strong, effort is cheap and illness bounces off. When Qi is weak, the same effort costs double — which is why people with Qi deficiency describe a heaviness that no amount of rest fully removes.
Traditional Chinese medicine links this pattern strongly to the Spleen and the Lung. The Spleen governs transformation and transport: how food becomes usable energy. The Lung governs the defensive Qi that sits on the surface of the body. Weakening either one leaves you short of both stamina and resistance.
The practical picture is that the recovery curve is wrong, not the effort curve. Someone with Qi deficiency can work hard, but they do not bounce back overnight. This is why constitution sits above energy: the pattern usually has causes you can act on — poor sleep, chronic stress, an irregular diet, or a long illness that has not fully resolved.
