The cardionomic circuit consists of the adrenal glands, cardiovascular system (CVS), and the autonomic nervous system (ANS). Activation of the cardionomic circuit starts when stress arrives on our doorstep. Starting at the brain and ending at the adrenal glands, the hypothalamic-pituitary-adrenal (HPA) hormonal axis is the first responder and main conduit that regulates our body’s everyday stress response. At the adrenal glands, cortisol output rises and acts as the body’s primary de-stressing hormone.
The cardiovascular system (CVS) and the autonomic nervous system (ANS) parts of the cardionomic circuit are also activated but largely placed on standby when stress is mild. It is only put on full throttle when stress is severe and cortisol output falls. This usually occurs after extended stress beyond our adrenal glands ability to handle, resulting in falling cortisol output. Clinically, we call this the state of adrenal exhaustion.
Therefore, the activation of the triad responsible for this circuit is progressive and tiered accordingly to the level of stress perceived. In other words, when stress is mild, not all parts of the triad need to be fully activated. The HPA hormonal system alone targeting the adrenal glands is sufficient to help the body deal with stress through the hormone cortisol. When stress is severe or chronic, the body may need more assistance.
Having three parts (the triad) working seamlessly together as one interconnected circuit balances the workload and prevents overuse of any one system (which can lead to dysfunction). Each part of the circuit is therefore called upon on an “as needed basis” as the body sees fit and they work synergistically with each other in a well-orchestrated progression.
