Our Limbic System in our brains deals with our emotions memories and sensory arousal in relation to movement.
We see when using different therapies, that releasing past stresses or emotions promotes a reduction in pain in areas associated with it. We also see an improvement in mobility.
This makes sense as painful thoughts keep us in a baseline sympathetic nervous system (aka flight or fight). Do you feel flexible if u tense up and hold your breath? Probably not.
Practitioners see this all the time. Working on specific areas of the body and clients report feeling upset and recalling old memories out of no where.
Pain has to go somewhere.
So the next time you hear someone say, I'm gonna keep myself busy to NOT think about or deal with an issue. Give them the long of short of why they shouldn't.
