Adrenaline vs. Cortisol: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 16, 2023
Adrenaline is a fast-acting stress hormone, triggering the fight-or-flight response; cortisol, a slower-acting hormone, maintains stress response and energy.

Key Differences

Adrenaline, produced by the adrenal glands, rapidly prepares the body for action in high-stress situations, enhancing physical performance and alertness. Cortisol, also from the adrenal glands, regulates a variety of processes including metabolism and immune response, particularly in prolonged stress.
