Cortisol is a hormone produced by the adrenal glands, which are located on top of each kidney. It plays a crucial role in helping the body respond to stress, regulate metabolism, and maintain blood sugar levels. Often referred to as the "stress hormone," cortisol is released during stressful situations, preparing the body for a "fight or flight" response. While cortisol is essential for health, too much of it over time can lead to problems like weight gain, high blood pressure, and anxiety. Maintaining a balanced level of cortisol is important for overall well-being, and practices like exercise, meditation, and proper sleep can help manage its levels effectively.
