Which hormone is called fight-flight hormone?

The hormone called ‘fight-flight hormone’ is [B] Adrenaline. Adrenaline, also known as epinephrine, is produced by the adrenal glands in response to stress or danger. It prepares the body for the “fight or flight” response by increasing heart rate, dilating air passages, and redirecting blood flow to essential organs like the muscles and brain. Adrenaline also triggers the release of stored glucose and fatty acids into the bloodstream to provide immediate energy for physical exertion.
This hormone plays a crucial role in survival, enabling rapid physiological changes to cope with threatening situations.

While adrenaline is essential for short-term stress responses, chronic activation can have detrimental effects on health. However, its acute effects are vital for increasing alertness and physical performance during emergencies or challenging situations, allowing individuals to react quickly and effectively to perceived threats. Thus, adrenaline is often referred to as the ‘fight-flight hormone’ due to its role in preparing the body for action in response to stressors.
