What is "epinephrine"?

Epinephrine, also known as adrenaline, is a hormone and neurotransmitter produced by the adrenal glands in response to stress or danger. It plays a crucial role in the body's "fight or flight" response, increasing heart rate, blood pressure, and energy availability to prepare the body for immediate action. Epinephrine also helps dilate airways, improve blood flow to muscles, and enhance cognitive function, aiding in heightened alertness and focus during stressful situations.
