Cortisol
The stress hormone that regulates the body's stress response and metabolic balance
Definition & Mechanism
Cortisol is a glucocorticoid hormone secreted by the adrenal cortex, playing a crucial role in stress response and metabolism. It is regulated through the hypothalamic-pituitary-adrenal (HPA) axis.
Cortisol influences our physical and psychological state through several mechanisms:
- Regulating blood glucose levels
- Influencing immune system function
- Controlling metabolism
- Affecting mood and cognition
- Managing inflammation
Maintaining appropriate cortisol levels is essential for physical health and stress management.
Release Timing
Understanding cortisol secretion patterns and influencing factors
Circadian Rhythm
Cortisol follows a circadian rhythm, typically peaking in the morning and gradually declining, reaching its lowest at midnight.
Stress Response
The body increases cortisol secretion when facing stressful situations to cope with challenges.
Physical Activity
Intense exercise and physical illness stimulate cortisol secretion.
Emotional State
Negative emotions like anxiety and depression can affect cortisol secretion patterns.
Natural Release Pattern
Cortisol secretion follows a distinct circadian rhythm.
Beyond baseline secretion, stress events trigger additional release.
