What Is Cortisol?


Cortisol is a steroid hormone produced in the cortex of the adrenal glands. It is released by the adrenal glands in response to stress. Cortisol is secreted in the largest quantity in the morning.,
It is sometimes called the “fight or flight” hormone because it initiates a cascade of physical responses to stress, including increased heart rate and providing your body with a quick jolt of energy. It does this by rapidly increasing the amount of sugar in the bloodstream through a process known as glycogenolysis. Cortisol also aids in the metabolism of fat, protein and carbohydrates, and acts to suppress the immune system. Cortisol is essential for health, but too much cortisol related to stress can be very damaging to your health.
