adrenalin
Fight-or-flight chemical
Adrenalin 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, surging energy.
Figuratively, adrenalin describes any rush of excitement or intensity: The adrenalin was pumping as we approached the finish line.
Also spelled adrenaline.
