A panic attack is a sudden, intense surge of nervous system arousal, the same fight-or-flight response that would prepare your body to escape danger, switching on when there is no danger present. It builds rapidly, most panic attacks last between five and 20 minutes, and the attack itself is not harmful even though it feels overwhelming.
This page explains what is actually happening in your body during an attack, why the nervous system fires a false alarm, how a panic attack differs from anxiety and from chronic fight-or-flight activation, and what helps the body stand back down.
Dr Safeera Kholvadia is a medical doctor who works with exactly this presentation at The Reset Room in Houghton Estate, Johannesburg, where panic attacks are approached as a nervous system pattern, not a character flaw.
What Happens in the Body During a Panic Attack
A panic attack is a whole-body physiological event. The autonomic nervous system, the part that runs your heart rate, breathing and digestion without conscious input, suddenly shifts into high sympathetic activation. The body receives a full danger mobilisation, and every symptom below is part of that mobilisation rather than a sign of physical disease.
The United Kingdom’s National Health Service describes the experience as a rush of intense mental and physical symptoms that come on very quickly, often for no apparent reason. The most common symptoms are physical and arrive together:
- Racing or pounding heartbeat
- Sweating and trembling
- Shortness of breath or a feeling of being smothered
- Chest tightness or pain
- Nausea or stomach churning
- Dizziness, lightheadedness or feeling faint
- Tingling in the hands, feet or face
- Hot flushes or chills
- A feeling of detachment from your body or surroundings
- Fear of losing control, “going crazy” or dying
Each symptom has a mechanical explanation. Adrenaline raises the heart rate. Fast, shallow breathing drops carbon dioxide levels, which causes tingling and dizziness. Muscles tense for action and produce trembling and chest tightness. Nothing in that list is random, and none of it is your body failing.
Why the Nervous System Sounds a False Alarm
The false alarm comes from the body’s threat-detection system, not from the situation you are in. Your nervous system constantly scans for safety and threat below conscious awareness. When that threat-detection system becomes sensitised, through accumulated stress, trauma, exhaustion or a period of heightened vigilance, it starts to respond to internal sensations as though they were external dangers.
A racing heart becomes the trigger for more adrenaline. More adrenaline makes the heart race further. The loop feeds itself for several minutes and then, because the body cannot sustain peak activation indefinitely, it subsides. That is why attacks end on their own and why the aftermath often feels like exhaustion rather than relief.
Stephen Porges’s polyvagal theory, which describes the autonomic nervous system as moving between states of mobilisation and safety, is a useful map for many patients, and it is the framework behind much modern nervous system regulation work. It is practice literature rather than settled physiology, and a physician-led practice will tell you so honestly, but it describes the lived sequence of an attack, alarm, mobilisation, collapse into exhaustion, more accurately than any simple “just calm down” instruction.
The clinical approach used at The Reset Room treats this sensitisation as the treatable layer. You can read the fuller picture on the practice’s nervous system regulation page, which explains how regulation work targets the alarm system itself rather than only its symptoms.
Panic Attack, Anxiety, or Chronic Fight-or-Flight
These three terms describe different shapes of the same nervous system, and telling them apart matters because they respond to different approaches. A panic attack is an acute episode. Anxiety is a persistent state. Fight-or-flight activation is the chronic background version that many people live in for years without naming it.
| Pattern | What it is | Time course | Typical experience |
|---|---|---|---|
| Panic attack | Acute surge of autonomic arousal | Builds in minutes, most last 5 to 20 minutes | Sudden physical storm, fear of dying |
| Anxiety | Persistent worry and physical tension | Hours to days, waxes and wanes | Background dread, muscle tension, racing thoughts |
| Chronic fight-or-flight | Sustained sympathetic activation | Weeks to years | Jumpiness, poor sleep, exhaustion, never fully relaxing |
One pattern can turn into another. Untreated chronic activation lowers the threshold at which a panic attack fires, and the fear of having another attack can itself keep the alarm system primed. The NHS describes this as a cycle of living in fear of fear, which is precisely the loop that treatment aims to interrupt.
How to Help the Body Stand Down
A panic attack ends on its own, and the goal during one is to stop feeding it rather than to fight it. Fighting the sensation adds threat signals. Three responses help most people:
- Name what is happening. Silently stating “this is a panic attack, it peaks and passes” engages the thinking brain and interrupts the catastrophising loop.
- Slow the exhale. Letting each out-breath run longer than the in-breath signals the parasympathetic side of the nervous system. Breathing hard and fast, by contrast, adds the very symptoms that fuel the attack.
- Ground through the senses. Firm pressure under your feet, a cold glass of water, or naming five things you can see gives the threat-detection system present-moment input instead of internal signals.
One caution belongs here. Chest pain, breathlessness and collapsing are also symptoms of genuine cardiac and medical emergencies, and a first panic attack should always be assessed by a medical doctor so that physical causes are ruled out properly. A diagnosis of panic attacks is something a clinician confirms, never something you should have to self-diagnose.
When Panic Attacks Keep Happening
Recurrent, unexpected panic attacks can develop into panic disorder, a recognised anxiety condition. The UK’s National Institute for Health and Care Excellence manages panic disorder under its guideline on generalised anxiety disorder and panic disorder in adults, which recommends structured psychological treatment as the foundation of care, with medication considered where psychological approaches are insufficient or poorly tolerated.
Because international guidance favours treating the pattern rather than only the episode, an assessment is worth doing earlier rather than later. A medical workup rules out physical drivers, thyroid dysfunction, cardiac causes, stimulant use and medication effects can all mimic or trigger attacks. Once medical causes are excluded, the sensitised alarm system itself becomes the target of treatment.
In South Africa, the South African Depression and Anxiety Group provides telephonic support and can help you find treatment pathways if panic attacks are affecting your life. A physician-led practice like The Reset Room offers the medical assessment first and the nervous system work second, in that order, which is the sequence this presentation deserves.
What Most People Get Wrong About Panic Attacks
- Believing the attack is dangerous. The sensation of dying is a symptom of the adrenaline surge, not a prediction. The attack peaks and passes whether or not you believe it will.
- Breathing harder to “get more air”. The breathlessness comes from over-breathing, not under-breathing, so fast deep breaths intensify the tingling and dizziness.
- Avoiding every place an attack happened. Avoidance teaches the alarm system that the location was the threat, which widens the trigger list instead of shrinking it.
- Waiting for it to stop on its own before seeking help. Panic attacks are highly treatable, and the fear-of-fear cycle deepens with time, so early assessment shortens the whole episode of care.
- Treating only the episodes. The attacks are the visible spikes of a background activation pattern, which is why work that addresses the underlying regulation, like the practice’s ARC Method framework, aims at the level below the spikes.
How The Reset Room Approaches Panic Attacks
Panic attacks sit squarely inside the practice’s core work. The Reset Room is a neuro-somatic clinical studio led by a medical doctor, which means the medical ruleout and the nervous system treatment happen under one roof. Assessment first, then regulation work that retrains the alarm system, is the practice’s sequence for exactly this presentation.

Frequently Asked Questions
Can a panic attack harm me or kill me?
A panic attack is not medically dangerous, even though the fear of dying during one feels completely real. The symptoms come from a surge of adrenaline and over-breathing, and the body ends the activation on its own. A first attack should still be medically assessed to rule out physical causes.
How long does a panic attack last?
Most panic attacks last between five and 20 minutes. The surge builds within minutes, peaks, and then subsides as the nervous system cannot sustain peak activation. Many people feel drained rather than relieved afterwards.
Why do panic attacks happen for no reason?
Panic attacks feel reasonless because the trigger is internal, not external. A sensitised threat-detection system responds to body sensations like a racing heart as though they were dangers, releasing adrenaline and starting the loop. Accumulated stress, trauma and exhaustion sensitise that system.
Is a panic attack the same as anxiety?
No. A panic attack is an acute episode of autonomic arousal lasting minutes, while anxiety is a persistent state of worry and tension lasting hours or days. Recurrent unexpected panic attacks can develop into panic disorder, which is a recognised anxiety condition.
What treatment helps panic attacks?
Guidelines such as NICE CG113 recommend structured psychological treatment as the foundation of care for panic disorder, with medication considered where psychological approaches are insufficient. A medical assessment first rules out physical causes, after which nervous system regulation work targets the sensitised alarm system itself.
