Much is still unknown about how cannabinoids, including CBD, work. Research shows that CBD interacts with cells and proteins in the brain. To better understand how CBD works, it is helpful to understand the endocannabinoid system (ECS).

The endocannabinoid system is a complex cell-signaling system that plays a role in regulating an array of internal functions and processes, such as sleep, memory, appetite, mood, and fertility. Regardless of whether you use cannabis or not, the endocannabinoid system is present and active in your body.

The endocannabinoid system involves three core components:

• Endocannabinoids: Molecules made by your body to help keep internal functions running smoothly.
• Endocannabinoid receptors: Found mostly in the peripheral nervous system or central nervous system. Endocannabinoids bind with these receptors to communicate that the ECS needs to act.
• Enzymes: Responsible for breaking down endocannabinoids once they have fulfilled their function.

While it isn’t fully known how CBD interacts with the endocannabinoid system, we do know that it doesn’t bind to the endocannabinoid receptors in the same way as THC. It may prevent the break-down of endocannabinoids, allowing them to have a greater effect on your body, or it may bind with an as-of-yet-undiscovered receptor.

In summary, CBD interacts with the endocannabinoid system, which may affect the sleep cycle. It may also decrease pain and anxiety, which can both inhibit restful sleep.
