Sometimes, we might witness someone seemingly "break down" right before our eyes. They might start shaking, crying, or screaming, or, conversely, freeze, become unresponsive, or appear disconnected from reality. Such behavior can be confusing and even frightening to those around them. Yet, this behavior is often an acute stress reaction (ASR). 

An ASR is a normal psychological response to abnormal circumstances. It's a short-term condition that occurs immediately after a traumatic situation. For instance, it can happen after the loss of a loved one, an experience of violence, a significant injury, or an accident. It can even occur simply by witnessing another person experiencing trauma. In these moments, the mind doesn't have time to process the event, shifting instead into a survival mode. 

What are the Signs of an Acute Stress Reaction? 

First, you'll likely notice behavioral changes. For example, a person might become extremely restless or, conversely, abruptly freeze. They might also try to flee or avoid reality as much as possible. Complete silence and a lack of any reaction when you speak to them are also common. Extreme stress can even lead to fainting. 

Physically, an ASR can manifest as tremors, nausea, numbness, a rapid heartbeat, and heavy, uneven breathing. Emotionally, there are two distinct possibilities: a vivid expression of emotions (like screaming, crying, or hysterics) or a complete absence of any emotions, giving the impression that the person has "frozen." Cognitive processes will also be challenging; the person may feel disoriented, "as if in a dream," struggling to find the right words or answer questions logically. 

How can you help?

Once you've determined that someone is experiencing an acute stress reaction, the question becomes: what should you do to help? 

• First and foremost, assess your own state. If you also feel destabilized and need assistance, prioritize taking care of yourself. If you feel you have enough resources to help, here are some simple but effective strategies:
• Offer, but don't insist. Ask if they need your help. Try to speak clearly and calmly, without pressure. Say things like, "I'm here if you want me to be," "Would you like some water?", "Can I get you a blanket?", or "Can I hold your hand?" Sometimes, this gentle offer is enough.
• Simply be there. Often, that's all it takes. You don't need to be a psychologist or therapist; just your presence can be profoundly helpful. A simple "I'm with you" or "I'm here" is often the best thing you can say.
• Avoid promises or advice. Phrases like "everything will be fine," "calm down," "why are you reacting like that?", or "don't cry" are counterproductive. They aren't about helping; they're about judging or dismissing their feelings. Instead, try saying, "I can see this is difficult for you. I'm here for you."
• Encourage calm breathing. Your calm, deep breathing can provide a sense of security. Offer to breathe together: "Breathe with me. Inhale — one, two, three, four. Exhale — one, two, three, four." A few such cycles can significantly improve the situation, as breathing is often severely impacted during an ASR.
• Don't rush them. Give their mind time to regain control. Avoid asking "what happened?" as their brain isn't capable of logical thought in that moment.
• Help them return to reality. Encourage them to look around and draw their attention to concrete things in the present moment. Say things like, "Look how green the grass is. You're wearing a blue sweater," and so on.

The "5-4-3-2-1" Technique

This grounding technique can be very effective: 

1. Name 5 things you can see around you (e.g., table, chair, carpet).
2. Name 4 things you can touch (e.g., your hand, a book, a pen).
3. Name 3 sounds you hear (e.g., someone's voice, the sound of a car, your own breathing).
4. Name 2 smells (e.g., cut grass, perfume).
5. Name 1 taste (e.g., the taste of gum, coffee, or candy).

An acute stress reaction usually resolves within a few hours or days. However, if the condition doesn't improve, or if the person experiences persistent sleep disturbances, nightmares, excessive anxiety, or flashbacks (vivid memories that make the traumatic situation feel like it's repeating), these may be symptoms of acute stress disorder or PTSD. In such cases, it's crucial to consult a psychotherapist. 

You don't need to be a specialist to offer support. Simply staying close, remaining calm, avoiding pressure, and not leaving the person alone can make a significant difference. Often, calm breathing nearby and offering water or tea are the first, most effective remedies
