Acute Stress Reaction (Acute Stress Reaction) | 마음스캔 심리학 용어사전

Details

Overview

Acute stress reaction refers to the intense psychological and physical response that occurs immediately after an unexpected traumatic event (accident, natural disaster, violence, sudden loss, etc.). It typically begins within minutes to hours of the event and most people naturally recover within days to weeks.

Key Features

Acute stress reaction is a natural protective mechanism through which the body and mind respond to danger:

Hyperarousal: Rapid heartbeat, insomnia, being startled by small noises

Dissociation: Feeling detached from reality, as if watching a movie

Avoidance: Wanting to avoid places or situations associated with the event

Re-experiencing: Recurring memories of the event or nightmares

Emotional changes: Rapid shifts between anxiety, sadness, and anger

These reactions are the mind's natural defense mechanisms designed to protect us in dangerous situations.

Coping Strategies

Ensure a safe environment first. Stay near people you trust

Get adequate rest and maintain regular meals and sleep

Don't suppress emotions. It's okay to cry

Talk to someone you trust if possible

If symptoms persist beyond 4 weeks, seek professional help

Avoid caffeine and alcohol, as they can worsen symptoms

Experiencing these reactions after a traumatic event is not a sign of weakness. It is the mind's natural process of self-protection. Most people gradually improve with time, but don't hesitate to seek help if needed.

💡 Real-Life Example

After witnessing a major car accident, being unable to sleep for days, heart racing at the sound of cars, and repeatedly reliving the accident scene are examples of an acute stress reaction.
