The fight-or-flight response is a physiological reaction to threats, involving the sympathetic nervous system and hormones like adrenaline and noradrenaline. It prepares the body for action, with changes such as an accelerated heartbeat and increased energy. This response has three stages: alarm, resistance, and exhaustion, and is crucial for survival. Modern life often triggers this response in non-threatening situations, highlighting the importance of managing stress.
