What Is Cortisol? (Cortisol Definition)

Cortisol (aka the stress hormone) is a hormone secreted by the adrenal gland in response to perceived stress. The secretion happens on the signal of the hypothalamus and pituitary gland (2). This process activates the fight-or-flight response to help us survive.

HPA Axis – Stress Hormone

Whenever the brain perceives stress, the hypothalamus releases corticotropin-releasing hormone (CRH) which activates the pituitary glands. The pituitary gland then releases adrenocorticotropic hormone (ACTH) which is carried by the blood to the adrenal gland. On receiving the signal, the adrenal gland releases cortisol to help the body deal with the stress. The whole system is known as the HPA axis (named after the organs) (3).

When the HPA axis is activated for the short-term, the release of cortisol helps us deal with potential threats. But the problem today is that our HPA axis is constantly activated because of the stress of the modern world.

What Does Cortisol Do? (Cortisol Function)

While acute stress can be a life saver, chronic stress is a real killer.

Acute stress (also known as eustress) is the good stress that helps you perform at your peak (4) and boosts your immune system (5).

Chronic stress (also known as distress is the root cause of many diseases that can kill you.

According to Hans Selye’s General Adaptation Syndrome Model, there are three stages of the stress response:

1. Alarm Phase

Eustress (the good stress) helps us deal with an immediate threat. It acutely increases cortisol, epinephrine, adrenaline, heart rate, blood pressure, breathing rate, strength, and release of sugar from the liver to provide fuel.

2. Resistance Phase

Long-term stress has the same effects, but the symptoms persist chronically. It gives rise to some additional symptoms like muscle tension, abnormal blood sugar, irregular blood pressure, and suppressed immune system.

3. Exhaustion Phase

This is when the body can’t cope with long-term stress and gives up. It can lead to several diseases and even death.
