    Stress Response (Fight-or-Flight Response)

    The stress response is the set of physical and emotional changes the human body makes in response to a threat or stress. It sometimes is called the "fight-or-flight" response.

    In a stressful situation, the body releases chemicals that trigger:

    • Increased heart rate and blood pressure.
    • Rapid breathing.
    • Increased sweating.
    • A sudden rush of strength.
    • Slowed digestion.
    • Dilated pupils.
