What Is Cortisol?
Cortisol is a hormone produced by the adrenal glands that helps regulate metabolism, blood pressure, blood sugar, immune function, and the body’s response to stress. It is often called the “stress hormone” because cortisol levels naturally rise during periods of physical or emotional stress.
Although cortisol is essential for normal body function, levels that remain too high or too low for long periods can contribute to health problems.
