Adrenaline
Fight-or-flight chemical
Adrenaline is a hormone released by the adrenal glands during stress, fear, or excitement, triggering the body's fight-or-flight response—increased heart rate, heightened alertness, and a surge of energy.
The term extends to any rush of excitement or intensity: the adrenaline of performing live, adrenaline junkie.
Also called epinephrine, especially in medical contexts.
