Cortisol

The primary stress hormone — released by the adrenal glands, elevated in chronic stress.

Cortisol is the main glucocorticoid hormone produced by the adrenal glands.¹ It is essential for life but becomes problematic when chronically elevated.

Normal Functions

  • Regulates metabolism and blood sugar
  • Modulates immune response
  • Supports wakefulness and alertness
  • Part of the stress response (HPA axis)

Chronic Elevation

  • Suppressed immune function
  • Impaired digestion and peristalsis
  • Reduced HRV
  • Anxiety, sleep disruption
  • Metabolic dysfunction

In ONDA Life

One marker of Part 1 progress is "reduced levels of basal cortisol." Level 1 practices activate the parasympathetic system, which downregulates the HPA axis and allows cortisol to return to healthy baseline levels.
