The term "stress hormone" primarily refers to cortisol, a hormone produced by the adrenal glands in response to stress. When faced with a stressful situation, the body releases cortisol to help manage the stressor. This hormone plays a crucial role in various bodily functions, including regulating metabolism, immune response, and blood pressure. In addition to cortisol, other hormones like adrenaline and norepinephrine are also released during stress. These hormones prepare the body for a "fight or flight" response, increasing heart rate and energy levels. While these hormones are essential for short-term stress management, chronic elevation can lead to health issues.
