What is the Origin of Allostasis in Wellness?

The term 'allostasis' was coined from the Greek words allos meaning 'variable' and stasis meaning 'standing' or 'stability,' to differentiate it from the more rigid concept of homeostasis. Its application in 'wellness' links this sophisticated physiological regulation to preventative health and optimal function. This framework helps clinicians understand how chronic stress and lifestyle factors contribute to hormonal dysregulation over time.

What is the Mechanism of Allostasis in Wellness?

The allostatic response is mediated by the primary stress response systems, including the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system, alongside metabolic and immune mediators. These systems release hormones like cortisol and catecholamines to adjust physiological parameters, such as heart rate and glucose metabolism, to meet the perceived demand. Successful allostasis allows the body to return efficiently to a baseline state, whereas chronic activation contributes to endocrine and metabolic imbalance.

Allostasis in Wellness

Meaning

Allostasis in wellness is the process by which the body actively achieves stability through physiological and behavioral change, moving beyond a single fixed internal set point, which is known as homeostasis. This dynamic regulatory capacity is vital for anticipating and responding to predictable or unpredictable challenges, thereby maintaining overall systemic integrity. When the cost of this continuous adaptation becomes excessive, it leads to allostatic load, which is a state of chronic wear-and-tear on the body’s systems.
