Fight-or-Flight Response

Definition

The fight-or-flight response is a physiological reaction that occurs when the body perceives danger or stress. It prepares the body to either confront the threat (fight) or escape from it (flight). This response is triggered by the release of hormones like adrenaline and cortisol, which increase heart rate, blood flow, and energy levels, allowing for rapid action.

Example

You are walking in a park when suddenly a large, aggressive dog starts chasing you. Your body immediately reacts: your heart races, your muscles tense, and your mind becomes focused on escaping the situation. You start running faster than usual, using all your strength to get away from the dog. This is an example of the fight-or-flight response in action, as your body is preparing to either fight off the threat or flee to safety.

Why it Matters

The fight-or-flight response is crucial because it allows humans and animals to react quickly to life-threatening situations, increasing chances of survival. However, chronic activation of this response due to prolonged stress can have negative effects on health, such as increased blood pressure, anxiety, and weakened immune systems. Understanding this response helps us manage stress more effectively and maintain overall well-being by recognizing when our bodies are overreacting to non-life-threatening situations.
