Does meditation override the action of adrenagernic receptors and control tension ?

For me the effect of meditation while sitting in a calm environment, either quiet or with soft music, clears my mind so that tense thoughts cannot exist due to counting each breath. I cannot focus on something tense because my mind is occupied focusing on sitting, breathing, and counting. As ones mind rests on the mundane, ones body relaxes, and I assume ones hormones normalize. However, I have neither measured my hormones nor read about such an excperiment.

This paper might be relevant to the OP. Also note that enhanced dopamine neurotransmission during meditation may increase noradrenergic releases in the prefrontal cortex (PFC). https://www.ncbi.nlm.nih.gov/pubmed/18615131
