Question:
Looking for some info on the physiology behind deep muscle relaxation.
Dates back to 1938, someone named Jacobson.
This is a technique used for stress reduction in which muscles are
tensed and then relaxed progressively in order to counter anxiety. The
psych textbooks say muscle relaxation is incompatible with a stress
reaction.
What though is the relation between muscle relaxation and anxiety?
Stress is usually associated with the sympathetic branch of the
autonomic nervous system. Why would muscle, which is part of the
somatic branch, have anything to do with this? Or looking at it
another way, why do stressed people have tense muscles?
Answer:
From what I have seen, Jacobsen pioneered a behavior therapy for
chronic pain and is more regularly used in Germany than in the States.
They don't always do and unstressed people have rigorous tonus as
well.
I think perhaps a somewhat related question is, why does visualization
affect the body, even without self conciously trying to physically move the
body parts into what is being visualized? Another example of our complexity
is bio-feedback.
A conjecture would be that there is a cognitive link between parts of our
nervous system. Or perhaps the division between sympathetic and autonomic
is more severe in the textbooks than in our bodies?
This probably could all be worked into a theory of improving weight-lifting
techniques, but I for one am not up to the task....
In fact, muscle relaxation techniques are used quite
a bit by the mainstream medical community a great
deal these days. They can be very effective in relieving
stress and in helping people get through chronic pain
and anxiety episodes without taking excess medications.
The old, Cartesian view of medicine separated mind and body.
This view has been significantly challenged in recent years by
clinical studies that support the mind/body connection.
