The science behind CBD muscle relaxation is relatively new, and no conclusive statements can be made about cannabidiol's ability to negate muscle pain. However, the endocannabinoid system is closely related to muscle relaxation, stress reduction, anti-inflammation, and more.
A variety of factors can play into muscle tightness. Exercise, work, posture, diet, stress, and more can influence the way we hold and experience our muscles. The endocannabinoid system (ECS) helps to reduce pain signals, reduce inflammation, and bring about a general sense of ease. A healthy ECS also helps to ensure proper mood balance and can help to manage muscle tightness.
Stimulation of CB1 and CB2 receptors with AEA (an endogenously produced cannabinoid) has been linked to smooth muscle relaxation and muscle contraction reduction. While dilation of smooth muscle does not directly relax your skeletal muscles, it can promote healthy blood flow to these regions. This blood flow can help stimulate muscle recovery and reduce perceived tension by delivering nutrients and oxygen to the muscles in need.
CB1 activation also influences the Ca2+ output of our cells, helping to create a healthy balance between relaxation and contraction in our skeletal muscles. Fascinatingly, CBD is known to boost AEA levels in the body by inhibiting the FAAH enzyme. This creates an exciting connection between cannabidiol and muscle relaxation, but it does not prove causation!
With time and extensive research, we will identify if CBD can produce the same muscle relaxation initiated by balanced CB1 and CB2 receptor activity.
