This is something I am looking into as well. Look up Alan Watts muscular tension. An interesting take on muscular tension in our bodies.. I am trying to relax. Also take a look at medications you are taking and their side effects on askapatient.com lots of medications you wouldn't suspect like allergy medications can cause muscle tension.. I have gone off all my medication and I am going to see where this takes me in a couple of months.. hope you are doing well.
