Which hormone is associated with the body's stress response?

Cortisol is the primary hormone associated with the body's stress response. It is produced by the adrenal glands in response to stress, particularly when the body perceives a threat or challenge. This hormone plays a crucial role in the "fight or flight" response by increasing glucose availability for energy, suppressing non-essential functions such as digestion and immune response, and aiding in the metabolism of fats, proteins, and carbohydrates.

Cortisol helps to maintain homeostasis during stressful situations and ensures that the body can respond effectively to stressors. Elevated cortisol levels can contribute to various physiological changes that prepare the body to handle acute stress. Understanding cortisol's role highlights its importance in both physical and psychological stress responses, thus illustrating why it is so closely tied to stress management and overall health.
