Panic attacks: What to do during an attack and how to prevent them long-term

Ananxiety attack oftenstrikeswithout warning: a racing heart, shortness of breath, trembling hands, and a feeling of impending doom or loss of control. It is one of the most intense experiences the body can produce, and one of the most common—about15% of the populationexperiencesat least one in their lifetime. This article answers two related questions:what to do during an attack to get through it, andhow to regulate your nervous system so it doesn’t happen again.

Recognizing a panic attack: typical symptoms

Ananxiety attack(or panic attack) is a sudden episode of intense fear accompanied by pronounced physical symptoms. The peak of intensity occurs within a few minutes, and the episode subsides within 10 to 30 minutes. The most common symptoms are:

• Heart palpitations, racing heart, sensation of tachycardia
• Shortness of breath, a feeling of suffocation, or a lack of air
• Tremors, cold sweats, chills, or hot flashes
• Dizziness, wobbly legs, feeling faint
• Nausea, a knot in the stomach, a tight feeling in the stomach
• Tingling, numbness, hands going numb
• A feeling of unreality(derealization) or of being detached from oneself (depersonalization)
• Intense fear: of dying, of going mad, of losing control

These symptoms may seem alarming, but they are not dangerous. They result from an alarm reaction in the autonomic nervous system —your body believes it is facing a life-threatening situation and activates all its emergency resources. The episode is intense because this reaction is designed to save your life. It is harmless because it resolves on its own.

Panic attack: What should you do? A 5-step emergency plan

When ananxiety attackbegins, your goal isn’t to make it go away through sheer willpower—that’s impossible, and trying to do so only makes it worse. Your goal is toride itout without fighting it. Here’s the sequence that works.

1. Recognize what is happening and put a name to it

“I’m having a panic attack right now. My body thinks there’s danger. There isn’t any. It’ll last 10 to 30 minutes, and then it’ll pass.” Simply putting it into words defuses some of the secondary fear (the fear of being afraid), which is often what causes the attack to spiral out of control.

2. Breathe out more slowly than you breathe in

During an attack, breathing becomes rapid and shallow—this is known as hyperventilation. It worsens symptoms (dizziness, tingling, a feeling of suffocation). The most effective technique for acute episodes:the 4-6 or 4-7-8 breathing technique. Breathe in through your nose for 4 seconds, then breathe out through your mouth for 6, 7, or 8 seconds. The long exhalation immediately activates the vagus nerve and sends a calming signal to the brain. Continue for 2 to 5 minutes.

3. Grounding attention in the physical present

The 5-4-3-2-1 method: name 5 things you see, 4 you touch, 3 you hear, 2 you smell, and 1 you taste. This exercise shifts your focus away from negative thoughts and brings you back into your body. A simple variation: place your feet flat on the ground and notice the contact, the weight, and the temperature.

4. Cool your face

Cold water on the face, an ice cube held in the hand, a cold shower: cold triggers the mammalian diving reflex, which instantly slows the heart rate via the vagus nerve. It is one of the few interventions that has an almost immediate effect on an established seizure.

5. Let it go, without running away

An untreated panic attack rarely lasts more than 30 minutes. The more you try to avoid the situation or fight the sensations, the more you reinforce the alarm response and increase the risk of a recurrence. The goal is toget through it, not to win.

Please note: TheNeoflo breathing beltcanhelp you through this moment by guiding your breathing through vibrations, but it is not a tool for stopping an attack—it is primarily a preventive tool. See below.

How long does a panic attack last?

Atypicalpanic attack lasts between 10 and 30 minutes, with the intensity peaking within 5 to 10 minutes. If it lasts longer than 30 minutes, it is considered a prolonged state of anxiety, which requires different types of treatment. If your attacks last several hours, or if they occur several times a week, this is a sign of chronic dysregulation that warrants a consultation with a general practitioner, a psychiatrist, or a psychologist.

Why Your Seizures Keep Coming Back: Dysregulation of the Autonomic Nervous System

An anxiety attack almost never happens “by chance.” It occurs against a specific backdrop: a chronically dysregulated autonomic nervous system, in which the sympathetic nervous system (alertness, vigilance, stress) consistently dominates the parasympathetic nervous system (recovery, calm). This imbalance lowers the brain’s alarm threshold—it takes less of a stimulus to trigger an emergency response.

What contributes to this underlying condition: chronic stress at work or at home, lack of sleep, overstimulation from screens, excessive caffeine, unresolved trauma, mental overload, and isolation. A panic attack is not the illness itself; it is thevisible symptom of an overloaded nervous system. Treating the symptom without addressing the underlying condition leads to recurrence.

That’s why many people who experience their firstpanic attack go on to have a second, then a third, and eventually develop a fear of being afraid—that’s the mechanism behindpanic disorder. The good news is that this condition is reversible. The autonomic nervous system can be trained, just like a muscle.

Prevention: 20 minutes a day to avoid the next crisis

The most well-documented breathing practice for sustainably regulating an out-of-balance nervous system iscardiac coherence: breathing at a rate of 6 cycles per minute using abdominal breathing for 15 to 20 minutes a day. This practice deeply stimulates the vagus nerve and increases heart rate variability (HRV), which is a direct marker of nervous system resilience.

The benchmark meta-analysis (Lehrer et al., 2020, 58 randomized clinical trials) demonstrates an effectcomparable to established treatmentsforanxiety and depression. Another recent meta-analysis (Kwon et al., 2025, 48 randomized trials) confirms that the benefits aredose-dependent. Five-minute sessions provide temporary relief; it is the15- to 20-minute sessionsrepeated dailythatbring about lasting change.

The Neoflo belt: a preventive tool (not for emergencies)

TheNeoflo breathing beltisdesigned for20 minutes of daily practice—the kind that prevents future attacks, not the kind that stops an attack in progress. Let’s be honest: during an active panic attack, it’s very difficult to stay still for 20 minutes, and the emergency technique (4-7-8 deep breathing + grounding) remains the most effective in the moment.

Where the belt really makes a difference isin the preparation phase: three haptic motors placed on the abdomen guide your breathing through touch, without a screen or app, making the 20-minute session easy to fit into your daily routine—with your eyes closed, while reading, watching a movie, or in bed at night. As the practice becomes established (4 to 12 weeks), the autonomic nervous system rebalances, the stress threshold rises, and panic attacks become less frequent and eventually disappear.

The Neoflo belt was invented by a biomedical engineer and co-developed with Dr. Thomas Cantaloup, a physician specializing in sleep and mental health. Bronze medalist at the 2024 Concours Lépine. Comes with an online training course and two 8-week support programs.

Panic Attack vs. Anxiety: Understanding the Difference

The terms "anguish" and"anxiety"areoften confused, but they describe two distinct phenomena that do not call for the same response.

• Anxietyisa vague and persistent emotion characterized by worry, rumination, underlying tension, and negative anticipation. It can last for hours, days, or weeks. Its physical symptoms are mild (muscle tension, digestive problems, fatigue, and light sleep).
• Anxiety(or an anxiety attack, panic attack) is a brief, intense episode characterized by sudden fear and pronounced physical symptoms, lasting 10 to 30 minutes. It is a peak in an otherwise steady state.

In the vast majority of cases, these two phenomena coexist: panic attacks arise against a backdrop of chronic anxiety. Treating only the attacks (with acute anxiolytics) without addressing the underlying condition leads to recurrence. Conversely, managing the underlying condition (daily routine, sleep, lifestyle, and sometimes therapy) reduces BOTH the attacks AND the underlying anxiety.

Managing Anxiety in Daily Life: Complementary Methods

Toalleviatelong-termanxiety, several approaches are needed. None is sufficient on its own; but when combined, they make a real difference.

• Daily breathing practice—20 minutes of cardiac coherence per day is the best-documented non-pharmacological intervention.
• Adequate and consistent sleep—sleep debt can disrupt the stress response within just a few nights.
• Moderate physical activity—brisk walking for 30 minutes a day, cycling, swimming. Avoid high-intensity sports that can trigger seizure symptoms.
• Limit stimulants—coffee, strong tea, alcohol, and nicotine: all of them lower your alertness threshold.
• Psychological therapies—CBT (cognitive behavioral therapy) is the gold standard treatment for panic disorder, with a success rate of 70–80%. EMDR or trauma-focused therapy are recommended when a traumatic event is the cause of the attacks.
• Meditation, sophrology, yoga—all useful as complementary practices, not as substitutes.

Sleep disorders are often linked to anxiety attacks:stress-related insomniacontributes tothis imbalance. A 20-minute session of deep breathing before bed helps you fall asleep more easily and improves the quality of your sleep—a twofold benefit.

When should you see a healthcare professional?

See a general practitioner, psychiatrist, or psychologist if:

• The attacks occur several times a week
• You develop a fear of being afraid, which limits your movements or activities
• These episodes are accompanied by unusual symptoms (unusual chest pain, loss of consciousness)
• If you are having dark or suicidal thoughts, call3114, a toll-free national hotline available 24 hours a day
• You are already taking medication, but the seizures aren't getting any better

Deep cardiac coherence and theNeoflo beltareuseful complementary tools in a comprehensive treatment plan—not a substitute for medical advice or psychotherapy when such treatment is indicated.

FAQ — Panic Attack

What are the first signs of a panic attack?

The first symptoms appear within a few seconds to a few minutes: a racing heart, shortness of breath, trembling, sweating, a knot in the stomach, dizziness, and a feeling of impending doom or loss of control. The peak is reached within 5–10 minutes, and the episode lasts 10–30 minutes in total.

How long does a panic attack last?

A typical panic attack lasts between 10 and 30 minutes. If it lasts longer than that, it is more likely a prolonged state of anxiety. If your panic attacks last longer or occur frequently, consult a doctor or psychologist.

Can an anxiety attack be prevented?

Yes, provided we address the underlying cause—that is, the chronic dysregulation of the nervous system that makes these episodes possible. The key strategies:20 minutes of cardiac coherence per day, sufficient sleep, regular physical activity, limiting stimulants (coffee, alcohol), and cognitive-behavioral therapy if the attacks recur. TheNeoflo beltfacilitatesdaily practice by guiding breathing through vibrations, without requiring concentration.

Is the Neoflo belt effective during a seizure?

The Neoflo belt is primarily apreventive tool, not a way to stop an attack. During an active panic attack, the most effective technique is 4-7-8 breathing (inhale for 4 seconds, exhale for 8 seconds) combined with the 5-4-3-2-1 counting technique and applying cold to the face. The belt can assist during this time by guiding the rhythm, but it truly demonstrates its full value during the daily 20-minute practice that prevents panic attacks from recurring.

Are there any natural remedies for anxiety?

Yes.Deepcardiac coherence,abdominal breathing, mindfulness meditation, and sophrology are all supported by a solid body of evidence. When combined with good sleep hygiene, physical activity, and limiting stimulants, they help regulate anxiety over the long term. Technological tools like the Neoflo belt make it easier to practice by eliminating the cognitive difficulty of screen-based guidance.

Anxiety Attack at Work: What Should You Do?

Find a quiet place for a few minutes (bathroom, hallway, car, park), and follow the emergency protocol (long exhale + 5-4-3-2-1 breathing exercise + splash cold water on your face if possible). Don’t try to keep working “as if nothing happened”—the crisis will subside more quickly if you give it 15–20 minutes. If these episodes at work keep happening, it’s often a sign of chronic work-related stress that warrants a consultation.

Nighttime anxiety attacks: why?

Nighttime panic attacks (which cause you to wake up with a start around 3 or 4 a.m.) are common and particularly frightening. They often occur when chronic stress has not been alleviated during the day. Regulating the nervous system throughcardiac coherence exercises in the evening before bedisone of the most effective ways to reduce their frequency and eventually eliminate them.

Take back control of your nervous system

An anxiety attack isn’t inevitable. It’s a sign that a tired nervous system needs to be retrained. TheNeoflo beltmakes iteasy to stick to a daily 20-minute practice—no screens, no mental effort, guided by touch. It comes with an 8-week program designed by a doctor.
