The hormone often referred to as the “stress hormone” is cortisol. Produced by the adrenal glands, cortisol plays a critical role in the body's stress response, helping to regulate metabolism, immune response, and blood pressure. Elevated levels of cortisol during chronic stress can have detrimental effects on health, such as increased risk of anxiety, depression, weight gain, and sleep disturbances. Understanding cortisol's role in stress management is essential for maintaining overall well-being and effective stress management strategies.
