The endocannabinoid system (ECS) is a regulatory network that helps maintain balance in the body. Through CB1 and CB2 receptors, it influences mood, pain, inflammation, metabolism, sleep, and immune function. When ECS signaling is disrupted, it may contribute to chronic conditions like migraine, IBS, fibromyalgia, and mood disorders. Supporting overall balance through lifestyle and targeted care may help restore healthy ECS function.
