Kortizol is a steroid hormone produced by the adrenal glands, which are located on top of each kidney. It plays a crucial role in various bodily functions, including regulating metabolism, reducing inflammation, and helping the body respond to stress. Often referred to as the "stress hormone," kortizol levels can increase during stressful situations, preparing the body for a "fight or flight" response. In addition to its role in stress response, kortizol helps control blood sugar levels, maintain blood pressure, and support immune function. However, chronic high levels of kortizol can lead to health issues, such as weight gain, high blood pressure, and weakened immune response.
