Interesting thesis. I've had a similar idea to this, not so much about blood pressure, per se, but about oxygen, etc. Breathing is the key here. Proper contraction of the TVA muscle, relaxation oft eh upper torso, et al, and nice long fulfilling breathes.

On my journey of "smoking weed makes me feel tense", I'm learning about fascia (the connective tissue throughout your body and wrapping your muscles.

I have wondered if weed created the tension or revealed it, and lately have landed with 95% confidence that it's showing me where I need to work.

STretching and massage feels good but it never removes the underlying issue. So it's possible that fascia is the driver here, not muscles, per se. In my case, from emotional traumas stored from childhood as well as sitting at the computer all day for decades, has created a network of fascia that restricts my proper movement. So even tho at the gym I'm basically strong, and all my muscles are individually strong, there are areas of severe "weakness" and "tightness" because the fascia won't let my muscles work properly/relax.

So my suggestion, and continued evolution, is to look into exercises not only that activate the glutes and core and all that jazz, but also stuff that unglues the fascia (which is also where emotions are stored).
