“[T]he NO,” writes Benson, “counteracts the norepinephrine and other stress secretions. Simultaneously, as the NO puffs billow forth in the brain and body, the brain releases calming neurotransmitters…such as dopamine and endorphins. As a result of these secretions, the blood vessels dilate or open up, the heart rate decreases, the stress response fades, and inner tranquility takes over.”
