The breathing exercises in this book have helped me a lot. My understanding is that a lot of the "chemical" problems peaters target through food and supplements (such as high cortisol, high serotonin, low thyroid, etc.) are often driven by chronic sympathetic shift in the nervous system due to what Reich called muscular armor. Basically, if your muscles become tense due to poor movement and suppressed impulses (practically a guarantee in our society), your body will come to the conclusion that you are in danger and will continuously trigger the stress cascade.
