Cortisol is a stress hormone the adrenal glands release. It helps your body deal with stressful situations, as your brain triggers its release through the sympathetic nervous system — the “fight or flight” system — in response to many different kinds of stress (1Trusted Source, 2Trusted Source).
While the short-term release of cortisol can help you run quickly from danger, when cortisol levels are too high for too long, this hormone can hurt you more than it helps (1Trusted Source, 2Trusted Source).
Over time, this can lead to an array of health issues such as weight gain, high blood pressure, diabetes, heart disease, insomnia or difficulty sleeping, mood irregularities, and low energy levels (1Trusted Source, 2Trusted Source).
