Stress seems to be an inescapable experience in life influenced by both internal and external circumstances. Stress disrupts homeostasis. Homeostasis according to the Britannica Dictionary is defined as, “any self-regulating process by which biological systems tend to maintain stability while adjusting to conditions that are optimal for survival”. When homeostasis is disrupted by stress this becomes apparent on multiple fronts, behaviourally, in our cognitive functioning, in our subjective experiences, and in our physiology.
Chronic stress releases high levels of cortisol in the brain, which hijacks the prefrontal cortex, thereby inhibiting logical thinking. Cortisol is often referred to as the stress hormone. Stress enlarges the amygdala, and the body is increasingly vulnerable to immune issues and feeling exhausted.
Combatting Stress
When our system no longer experiences homeostasis, there are four main chemicals in the brain that we need to focus on to create a sense of wellbeing – serotonin, dopamine, oxytocin, and endorphin. The following diagram suggests activities that trigger their release in our brain to counteract the effects of short- or long-term stress, thereby restoring homeostasis.
Due to the effects of stress, we can experience reduced energy levels or desire to incorporate changes into daily routines. To commence the journey, it needs to be an ‘act of our will’ rather than waiting for a ‘feeling or desire’. Slowly integrate new activities into your daily schedule and notice the changes that ensue. When you begin to experience homeostasis again that will provide the momentum for sustained change.
