If you’re having a panic attack right now, the most important thing to know is that it will pass. Panic attacks peak within 10 minutes and rarely last longer than an hour. You are not dying, you are not losing control, and your body is doing something it was designed to do, just at the wrong time. Below is exactly what to do during an attack, what’s happening in your body, and how to recover afterward.
What to Do Right Now
Stop what you’re doing and focus entirely on your breathing. Your body has flooded itself with stress hormones, and the fastest way to counteract that is to slow your exhale, which activates the calming branch of your nervous system. Try box breathing: breathe in through your nose for four seconds, hold for four seconds, breathe out through your mouth for four seconds, hold again for four seconds. Repeat this cycle for two to three minutes. If holding your breath feels uncomfortable, just focus on making your exhale longer than your inhale.
Once your breathing feels slightly more under control, use a grounding technique to pull your attention out of your body and into your surroundings. The 5-4-3-2-1 method works well: name five things you can see, four things you can physically touch, three things you can hear, two things you can smell, and one thing you can taste. This isn’t a trick. It forces your brain to process sensory information, which competes with the fear signals causing the attack.
Other things that help in the moment: press your feet firmly into the floor, hold something cold like an ice cube or a cold water bottle, or splash cold water on your face. Movement helps too. If you can, walk slowly and deliberately. Avoid fighting the sensations or telling yourself to “calm down.” Resistance tends to intensify the panic. Instead, let the wave move through you while you anchor yourself with breathing and grounding.
What’s Happening in Your Body
A panic attack starts in a small, almond-shaped brain structure that acts as your danger detector. When this area perceives a threat, real or not, it can bypass your brain’s rational processing centers entirely and trigger an emergency response before you’ve had a chance to evaluate what’s actually happening. This is sometimes called an “amygdala hijack,” and it explains why panic attacks feel so sudden and overwhelming.
Once that alarm fires, your fight-or-flight system takes over. Your heart rate spikes, your breathing speeds up, you start sweating, and blood redirects to your large muscles. You might feel dizzy, numb in your hands or face, nauseous, or like you can’t get enough air. Some people feel a sense of unreality, as if the world around them isn’t quite real or they’re watching themselves from outside their body. All of these sensations are normal parts of the stress response. They feel terrifying, but they are not dangerous.
What a Panic Attack Feels Like
Clinically, a panic attack involves the sudden onset of intense fear along with at least four physical or psychological symptoms. The most common include a racing or pounding heart, shortness of breath, trembling, chest pain, dizziness, chills or waves of heat, nausea, and a fear of dying or losing control. Not every attack looks the same. Some are milder, with only a few symptoms lasting a few minutes. Others come in rolling waves of varying intensity that can stretch over several hours, even though each individual peak still resolves within about 10 minutes.
Panic Attack vs. Heart Attack
Chest pain during a panic attack understandably makes people think they’re having a heart attack. The two feel different in several important ways. Panic attacks typically cause sharp or stabbing chest pain that stays in the chest. Heart attacks feel more like pressure, squeezing, or a heavy burning sensation, and the pain often radiates into the arm, jaw, or neck.
Timing matters too. Heart attacks tend to follow physical exertion, like shoveling snow or climbing stairs, and the pain doesn’t fully go away. It may fluctuate in intensity but persists or returns in waves. Panic attack symptoms peak quickly and then fade, usually leaving you feeling drained but pain-free. If your chest pain started after physical strain, radiates beyond your chest, or doesn’t improve after 20 to 30 minutes, treat it as a potential cardiac event and call emergency services.
The “Panic Hangover” Afterward
Once the attack subsides, you may feel like you just ran a marathon with no warm-up. This post-attack exhaustion is sometimes called a panic hangover or adrenaline hangover, and it’s the predictable aftermath of your body dumping stress hormones and then crashing. Physical exhaustion is the most obvious sign. You might feel heavy, drained, and desperate to sleep.
Brain fog is common too, making it hard to think clearly or hold a conversation. Your muscles may ache, especially in your neck, shoulders, and back, from all the tension you were carrying. Emotionally, people describe feeling numb, detached, irritable, or embarrassed about what just happened. Some feel a lingering sense of vulnerability or dread that another attack could come. All of this is normal and typically fades within a few hours to a day.
What helps recovery: drink water, eat something small if you can, and rest without guilt. Gentle movement like a short walk can help clear residual adrenaline. Avoid caffeine and alcohol for the rest of the day. If you can, tell someone you trust what happened. Isolating afterward tends to feed the cycle of shame and anxiety.
Preventing Future Attacks
A single panic attack doesn’t mean you have panic disorder. But if attacks are recurring, there are effective treatments. Cognitive behavioral therapy is the most well-supported approach. It teaches you to recognize the early signs of panic, reinterpret the physical sensations as non-dangerous, and gradually reduce avoidance of situations you’ve come to associate with attacks.
On the medication side, SSRIs (a class of antidepressants) are typically the first-line option for ongoing panic. They take several weeks to reach full effect, but they reduce the frequency and intensity of attacks over time. Benzodiazepines like Xanax or Klonopin work faster and are sometimes prescribed for short-term or situational use, but they carry a risk of dependence and are generally not recommended as a long-term solution.
Day-to-day habits also make a measurable difference. Regular aerobic exercise, consistent sleep, and limiting caffeine all lower your baseline anxiety level, which makes it harder for your brain’s danger detector to misfire. Practicing box breathing or grounding techniques when you’re calm trains the skill so it’s accessible when you actually need it. Think of it like a fire drill: the rehearsal is what makes the real thing manageable.
