In Traditional Chinese medicine they distinguish between different types of energy or Qi. Your Qi has five functions:
Actuation: Physical processes in the body, like circulation of fluids.
Warming: Especially in the limbs
Defense: Against pathogenic factors or disease
Containment: Keeping blood, urine, semen, sweat from leaking
Transformation: of food and beverages into breath and then into qi.
It is the belief that Qi is generated from your food and beverages and a bit from breathing. The other part of Qi is inherited from your parents, and gets used over the course of your life.
