adrenaline release
Fight-or-flight surge
Adrenaline release is the body's surge of epinephrine in response to stress, danger, or excitement—the fight-or-flight response.
The phrase describes both the physiological event and the feeling it produces: heightened alertness, rapid heartbeat, and a rush of energy.
The adrenaline release from skydiving is addictive.
People seek it through extreme sports, horror films, or intense competition.
