Cortisol is also known as the “stress hormone” because of its connection to the stress response, however, it’s much more than just a hormone released during stress. Cortisol can help control glucose levels, regulate metabolism, help reduce inflammation, and assist with memory formulation. It has a controlling effect on the body’s salt and water balance and helps control blood pressure. In women, cortisol also supports the developing fetus during pregnancy. Heat, cold, infection, trauma, stress, exercise, obesity, and debilitating disease can influence cortisol levels. The hormone is secreted in a daily pattern rising in the early morning, peaking around 8 am, and declining in the evening. This pattern, which is sometimes called the “diurnal variation” or “circadian rhythm” changes if you work irregular shifts (such as the night shift) and sleep at different times of the day.
