Cortisol is a key neuroendocrine biomarker used to measure allostatic load [1], [2], and its dysregulation—whether through excessive release or blunted response—is a primary mechanism contributing to the accumulation of allostatic load [3], [4], [5].

claimWhen the sympathetic nervous system (the 'fight-or-flight' system) is activated by stress, respiration rate increases, breathing becomes shallow and rapid, heart rate increases, blood pressure spikes, and cortisol levels rise, which contributes to allostatic load over time.

claimActivation of the sympathetic nervous system (the "fight-or-flight" system) increases respiration rate, leading to shallow breathing, increased heart rate, spiked blood pressure, and cortisol release, which contributes to allostatic load over time.

claimSlow, deep breathing at a rate of approximately 5-6 breaths per minute enhances parasympathetic activity through vagal pathways, which reduces sympathetic arousal, lowers cortisol, improves heart rate variability, and mitigates allostatic load.

claimSlow, deep breathing, particularly at a rate of approximately 5-6 breaths per minute, enhances parasympathetic activity (the 'rest-and-digest' system) through vagal pathways, which reduces sympathetic arousal, lowers stress hormones like cortisol, improves heart rate variability, and mitigates allostatic load.

claimNeuroendocrine markers used to measure allostatic load include cortisol, dehydroepiandrosterone sulphate (DHEA-S), corticotropin-releasing hormone (CRH), epinephrine, and norepinephrine.

procedureHealthcare professionals measure allostatic load in clinical practice by assessing a composite score derived from biomarkers including neuroendocrine markers (e.g., cortisol), cardiovascular markers (e.g., blood pressure, heart rate variability), metabolic markers (e.g., glucose, lipid profile), and inflammatory markers (e.g., C-reactive protein).

claimAllostatic load accumulates through three primary mechanisms: frequent stress responses creating cumulative burden, failed shut-down of stress responses after stressors end, and inadequate physiological responses such as excessive inflammatory reactions or blunted cortisol release.

claimThere is a lack of agreement regarding which variables should be measured to determine allostatic load (AL) and allostatic overload (AOL), specifically whether to measure only mediators like cortisol or also contributing variables like age, gender, diet, habitat, and health behaviors.
