What does the 'fight or flight response' prepare a person to do?

The 'fight or flight response' is a physiological reaction that occurs in response to a perceived threat or danger. This response prepares a person to either confront the threat, which is the "fight" aspect, or to escape from it, which is the "flight" aspect. When faced with immediate danger, the body undergoes various changes: increased heart rate, heightened alertness, and the release of stress hormones like adrenaline. These changes are designed to equip an individual with the physical capability to respond to a crisis—either by fighting against the threat or running away to safety.

This response is critical for survival, as it enables quick reaction times and mobilizes the body's resources in the face of immediate danger. Engaging in social activities, performing mental calculations, or attempting to relax are not the focus of the fight or flight response; rather, the emphasis is on rapid physical action to ensure safety in threatening situations.
