Which hormone is released by the brain during stressful events?

Cortisol is recognized as the primary stress hormone released by the adrenal glands, which are regulated by signals from the brain in response to stress. When a stressful event occurs, the hypothalamus sends signals to the pituitary gland, prompting it to release another hormone called adrenocorticotropic hormone (ACTH). This hormone activates the adrenal glands to release cortisol into the bloodstream.

Cortisol plays a crucial role in the body’s stress response, helping to manage various functions such as metabolism, immune response, and blood pressure. It prepares the body to handle the immediate challenges posed by stress through its various physiological effects. Understanding the significance of cortisol in stress management can aid in comprehending how prolonged stress can affect overall health.
