Adrenalin/epinephrine is a neurotransmitter produced by and released from the adrenal glands. Release of this chemical activates the sympathetic nervous system through the alpha-adrenergic and beta-adrenergic receptor families and produces the classic “fight-or-flight response” including increased blood pressure, heart rate, and respiratory rate. While this system is adaptive in the context of acutely stressful events, prolonged stress can produce a chronic overactivation of the adrenergic system. This overactivation is implicated in the development and progression of chronic health problems including hypertension and coronary artery disease.
