adrenaline response
Stress hormone surge
The adrenaline response is the body's rapid physiological reaction to perceived danger or stress—heart racing, breathing quickening, muscles tensing.
Also called the fight-or-flight response, it prepares the body for immediate action: My adrenaline response kicked in when the car swerved toward me.
The term extends to any surge of intense alertness or energy triggered by excitement or threat.
