The most important thing you can do for someone having a panic attack is stay with them, stay calm, and help them slow their breathing. Panic attacks peak within about 10 minutes and then gradually subside, so your role is to be a steady, reassuring presence through that wave. Everything else builds on those basics.
Understanding what’s happening in their body helps you respond with confidence instead of fear. A panic attack isn’t a choice or an overreaction. It’s a neurological false alarm, and the person experiencing it genuinely feels like they’re in danger.
What’s Happening in Their Body
During a panic attack, the brain shifts activity away from the rational, planning-oriented frontal areas and toward deeper survival centers. Specifically, a region called the periaqueductal gray, which normally activates in response to immediate physical threats, fires as though the person is face-to-face with a predator. This triggers a full sympathetic nervous system response: racing heart, elevated blood pressure, trembling, sweating, chest tightness, and difficulty breathing.
One prominent theory is that the brain has a built-in suffocation alarm, and in people prone to panic attacks, this alarm gets triggered falsely. That’s why the feeling of not being able to breathe is so common and so terrifying. The person’s body is also flooded with norepinephrine (the brain’s adrenaline-like chemical), which ramps up arousal and intensifies every physical sensation. Meanwhile, GABA, the brain’s main calming neurotransmitter, is often functioning at lower levels in people who experience panic, meaning their natural braking system is weaker.
None of this is under the person’s conscious control. Knowing that helps you approach them without frustration or judgment.
Your First Steps
Stay with the person and keep your own composure. Your calm energy is the single most powerful tool you have. If you’re visibly anxious, it reinforces the sense that something is truly wrong.
Move them to a quieter spot if possible. Crowds, loud noise, and bright lights add sensory input that an already overwhelmed brain can’t process well. A quieter environment removes fuel from the fire. Once you’re somewhere calmer, ask them directly what they need. Don’t assume. Some people want to be held, others can’t tolerate being touched. Some want to talk, others need silence.
Speak in short, simple sentences. Their brain is in survival mode and can’t process complex information. Say things like “I’m right here,” “You’re safe,” or “This will pass.” Avoid surprises, sudden movements, or rapid shifts in what you’re doing. Be predictable.
What to Say (and What Not To)
The phrases that help most are simple, validating, and grounding. “I’m here for you, you’re not alone” works because it addresses the isolation panic creates. “What can I do to help you?” works because it gives them a small sense of control when everything feels out of control. If they can talk, asking “Do you want to do something to take your mind off this?” can redirect their attention.
What doesn’t help: telling them to “just calm down,” saying “it’s all in your head,” or asking them to explain what’s wrong. They often don’t know what’s wrong, and being pressed for an explanation adds pressure to an already overloaded system. Avoid minimizing phrases like “you’re fine” or “there’s nothing to worry about.” To their nervous system, the threat feels completely real, and dismissing it can make them feel more alone in the experience.
Help Them Breathe
Slowing their breathing is the most direct way to interrupt the panic cycle. Deep, slow breaths stimulate the vagus nerve, which sends signals to the brain to activate the parasympathetic nervous system, essentially telling the body to stand down from emergency mode. You can do this alongside them, which gives them a rhythm to match.
The simplest approach is box breathing: inhale through the nose for four counts, hold for four counts, exhale for four counts, hold for four counts, and repeat. If they can handle a slightly more advanced pattern, the 4-7-8 technique (inhale for four, hold for seven, exhale through the mouth for eight) is particularly effective at downregulating the nervous system because the long exhale forces the body to slow down.
There’s also a technique called physiological sighing that researchers have found effective. The person inhales slowly through the nose, then takes a second shorter inhale on top of it to fully expand the lungs, followed by a long slow exhale. A recent randomized controlled trial found that just five minutes of this daily for a month improved mood and reduced anxiety more than meditation alone. During an active attack, any of these patterns will help, so use whichever one the person can follow most easily.
If structured breathing feels like too much, even just counting slowly to 10 together can anchor their focus and naturally slow their breath.
Grounding Techniques That Work
Grounding pulls a person’s attention out of the internal spiral and into the present moment. The most widely recommended method is the 5-4-3-2-1 technique. Walk them through it step by step: name five things you can see, four things you can touch, three things you can hear, two things you can smell, and one thing you can taste. It doesn’t matter what the items are. A pen on a desk, the texture of their sleeve, the hum of an air conditioner. The point is to re-engage the senses and give the rational brain something concrete to do.
Another option is asking the person to repeat a simple physical action, like raising their arms overhead and lowering them, or pressing their palms together and releasing. Physically tiring tasks redirect the body’s energy and give the nervous system a controlled outlet for all that adrenaline.
After the Peak Passes
Panic attacks often peak within 10 minutes, but the aftermath can linger. Sometimes multiple waves of different intensity roll through over the course of an hour or more, which can feel like one continuous attack. Once the worst has clearly passed, don’t rush the person back to normal activity.
Encourage them to continue breathing slowly with their belly rising and falling for another 5 to 10 minutes. From there, a progressive muscle relaxation can help release the residual tension: starting at the toes and working up to the head, gently tightening each muscle group for a few seconds and then releasing. This pairs well with continued slow breathing and helps the body register that the emergency is truly over.
Give them time to return to full alertness before they drive or do anything requiring focus. The neurochemical hangover from a panic attack can leave a person feeling drained, foggy, or emotionally raw. Sitting quietly together, getting water, or taking a short walk outside are all reasonable next steps.
One of the most helpful things you can say afterward is a version of this: “That was uncomfortable, but you weren’t in danger, and it passed.” This isn’t dismissive. It’s a gentle reframe that, over time, helps the person build confidence that panic attacks are survivable and temporary.
Panic Attack or Heart Attack?
This is a genuine diagnostic challenge, and even emergency rooms sometimes struggle with it. Panic attacks frequently cause chest pain through several mechanisms: hyperventilation can strain the muscles between the ribs, acute anxiety can trigger esophageal spasms, and in some cases, the autonomic surge during panic can cause actual coronary artery spasm. Hyperventilation even produces changes on an EKG that mimic heart-related ischemia in people with and without heart disease.
Some general patterns can help you decide how to respond. Panic attack chest pain tends to be sharp or stabbing, localized to one spot, and accompanied by tingling in the hands, a sense of unreality, or a fear of going crazy. Heart attack pain more often feels like pressure or squeezing, may radiate to the jaw, neck, or left arm, and is frequently accompanied by nausea or cold sweats without the psychological terror of panic.
If the person has never had a panic attack before, is over 40, has risk factors for heart disease, or if the chest pain doesn’t resolve as the other symptoms fade, treat it as a potential cardiac event and call emergency services. It is always safer to get a false alarm checked out than to dismiss a real one.
