Symptoms of High Cortisol: Signs of Elevated Stress Hormones

Cortisol is often called the body’s “stress hormone” because it helps regulate your response to stress. Produced by the adrenal glands, cortisol plays an important role in controlling metabolism, blood sugar, blood pressure, inflammation, and the sleep-wake cycle.

While cortisol is essential for health, consistently high levels can negatively affect both physical and mental well-being. Understanding symptoms of high cortisol can help you recognize potential warning signs and take steps to support your health.
