Stres hormonu, known scientifically as cortisol, is a steroid hormone produced by the adrenal glands in response to stress. It plays a crucial role in various bodily functions, including regulating metabolism, reducing inflammation, and controlling the body's sleep-wake cycle. Elevated levels of cortisol can occur during stressful situations, preparing the body for a "fight or flight" response. Chronic high levels of stres hormonu can lead to negative health effects, such as anxiety, weight gain, and weakened immune function. Managing stress through techniques like exercise, meditation, and proper sleep can help maintain healthy cortisol levels and overall well-being.
