What Is Cortisol?
Cortisol is a hormone released by the adrenal glands in response to stress or low blood sugar. Often called the "stress hormone," it plays a vital role in various bodily functions, such as:
Regulating Blood Sugar: Cortisol helps maintain steady energy levels.
Reducing Inflammation: It dampens immune responses to reduce inflammation.
Managing Stress Responses: Helps the body cope with stress.
While cortisol is essential for survival, chronically elevated levels can negatively impact mental and physical health.

Mental Health Impacts
Excessive cortisol is associated with anxiety, depression, and difficulty concentrating. See the NHS Mental Health Overview.
Suppressed Immunity

Eat a Balanced Diet
Include cortisol-lowering foods like leafy greens, fatty fish, berries, and whole grains. Avoid excessive caffeine and sugar, which can spike cortisol levels.
Limit Alcohol
Overconsumption of alcohol can increase cortisol levels and disrupt sleep.
FAQs
What causes high cortisol levels?
Chronic stress, poor diet, insufficient sleep, and certain medical conditions like Cushing's syndrome can increase cortisol levels. Learn more about Cushing's syndrome from the NHS Cushing's Syndrome Guide.
Can cortisol be too low?
Yes, low cortisol levels, often due to adrenal insufficiency, can result in fatigue, weight loss, and low blood pressure.
