You – and nearly every other animal on the planet – have evolved an intricate physical network known as the Endocannabinoid System (ECS). The ECS regulates a wide variety of physiological processes like pain-perception, mood, memory, appetite, stress, immune function, and homeostasis. Homeostasis means keeping the bodily systems in balance. You can think of the ECS as the body’s universal regulator. If some of our internal systems are dialed-up too high or turned-down too low, it is the job of the ECS to bring everything back into equilibrium.
