adrenaline
Fight-or-flight chemical
Adrenaline is a hormone released by the adrenal glands in response to stress or excitement, triggering the body's fight-or-flight response—increased heart rate, heightened alertness, surge of energy.
The word often describes the feeling itself: an adrenaline rush, pure adrenaline.
Thrill-seekers chase it; performers channel it.
An adrenaline junkie craves dangerous or exciting activities.
