Most panic attacks peak within minutes and fade within 20 to 30 minutes, but the recovery process can stretch much longer. Your body floods with adrenaline and stress hormones during an attack, and those chemicals take time to clear. Cortisol levels stay elevated for roughly an hour after a panic attack begins, returning to normal somewhere around the two- to three-hour mark. Knowing what to do during that window, and in the hours and days that follow, makes a real difference in how quickly you feel like yourself again.
What’s Happening in Your Body
A panic attack triggers your fight-or-flight system. Your adrenal glands dump adrenaline into your bloodstream, which speeds up your heart rate, tightens your muscles, and shifts blood away from your digestive system. This is the same response your body would mount if you were in physical danger. The problem is that there’s no actual threat to run from, so all that energy has nowhere to go.
The adrenaline surge can linger for up to an hour depending on how intense the attack was. A brief scare might clear in minutes, but a full-blown panic episode keeps those stress hormones circulating longer. Meanwhile, cortisol (your body’s slower-acting stress hormone) peaks during the first 30 minutes and stays meaningfully elevated for about an hour before gradually settling back to baseline over the next two to three hours. This is why you can still feel off long after the panic itself has stopped.
Calming Down During the Attack
If you’re in the middle of a panic attack right now, start with your breathing. Slow, controlled breaths activate the part of your nervous system responsible for calming you down. Two techniques work well:
- Box breathing: Inhale for 4 seconds, hold for 4 seconds, exhale for 4 seconds, hold again for 4 seconds. Repeat.
- 4-7-8 breathing: Inhale for 4 seconds, hold for 7 seconds, exhale slowly for 8 seconds.
Both methods regulate your autonomic nervous system, lowering your heart rate and blood pressure. The extended exhale in particular signals your body that it’s safe to stand down. Don’t worry about doing it perfectly. Just focus on making each exhale longer than your inhale.
Once you’ve found a breathing rhythm, try the 5-4-3-2-1 grounding technique to pull your attention out of your head and into the present moment. Work through your senses one at a time: notice 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. This forces your brain to process concrete sensory information instead of cycling through fear. It doesn’t need to be anything special. A spot on the ceiling, the texture of your sleeve, the hum of a refrigerator. The point is to anchor yourself in what’s real and immediate.
The “Panic Hangover”
The attack itself may last under 30 minutes, but the aftermath is its own experience. Many people describe a “panic hangover” that includes physical exhaustion, brain fog, and muscle aches, particularly in the neck, shoulders, and back from all the tension your body held. You might feel drained and heavy, as if you could sleep for twelve hours. Thinking clearly or remembering things can feel unusually difficult.
Most people recover from this within several hours to two days. If you’re already dealing with chronic stress or sleep deprivation, the hangover can stretch up to a week. This is normal. Your body just went through the chemical equivalent of running from a predator, and it needs time to reset.
What to Do in the Hours After
The first few hours after a panic attack matter more than people realize. Your nervous system is still on high alert, and pushing yourself back into stressful situations too quickly can trigger another wave of anxiety. Here’s what actually helps during this recovery window:
Move gently. A slow walk, some light stretching, or any low-intensity movement helps your body metabolize the remaining adrenaline and cortisol. This isn’t the time for an intense workout, which can spike your heart rate and mimic panic sensations.
Hydrate and eat something. Panic attacks burn through energy. Your blood sugar may have dropped, and dehydration makes fatigue and brain fog worse. A glass of water and a small meal or snack can help stabilize your body faster.
Rest without isolating. Sleep if you need to. But if you’re awake, being around someone calm and safe can help your nervous system regulate. You don’t need to talk about what happened if you don’t want to. Just the presence of another person can be grounding.
Skip the caffeine. Your system is already flooded with stimulating chemicals. Adding caffeine on top of that can prolong the jittery, on-edge feeling and delay your return to baseline.
How to Help Someone Else Recover
If you’re with someone who just had a panic attack, the most important thing you can do is stay calm and stay present. Don’t leave them alone unless they ask you to. Speak in short, simple sentences. Avoid phrases like “just relax” or “there’s nothing to worry about,” which can feel dismissive when someone’s body is in full alarm mode.
Instead, ask them what they need. Help them focus on the present by guiding them through slow breathing: count to five on each inhale and exhale together. Gently and confidently reassure them that they’re safe and that the attack is temporary. That confidence matters. When your nervous system is in panic mode, borrowing someone else’s calm can be remarkably effective.
Recognizing What a Panic Attack Looks Like
Panic attacks involve at least four symptoms from a list of thirteen recognized indicators. These include a racing or pounding heart, sweating, trembling, shortness of breath, chest pain, nausea, dizziness, numbness or tingling, chills or hot flashes, feelings of choking, a sense of unreality or detachment from yourself, fear of losing control, and fear of dying. The combination varies from person to person and even from one attack to the next.
One reason panic attacks are so frightening is that several of these symptoms overlap with heart attacks: chest pain, shortness of breath, sweating, nausea, and dizziness appear on both lists. The key differences are in how they start and how long they last. Panic attacks hit suddenly and peak within minutes. Heart attack symptoms tend to build gradually and intensify over time. Panic symptoms typically fade within 20 to 30 minutes. Heart attack symptoms persist and don’t improve with rest or calming techniques. If your chest pain lasts more than a few minutes, gets worse, or doesn’t ease up with slow breathing, call 911. It’s always better to get checked and find out it was panic than to assume and be wrong.
Reducing Attacks Over Time
If panic attacks are recurring, the most effective treatment approach is a form of therapy called cognitive behavioral therapy, often combined with a specific technique called interoceptive exposure. This involves deliberately and safely recreating the physical sensations that trigger your panic, like a rapid heartbeat from running in place or dizziness from spinning in a chair, so your brain learns these sensations aren’t dangerous. Over time, your fear response to those body signals weakens. Studies show that 75 to 92 percent of people who complete this type of therapy become panic-free, and those results hold up at follow-up.
Between therapy sessions, building a daily routine that keeps your baseline stress lower makes attacks less likely. Regular sleep, consistent physical activity, and limiting stimulants all reduce the frequency and intensity of panic episodes. None of this is a quick fix, but it changes the underlying pattern rather than just managing individual attacks.
About 2.7 percent of U.S. adults experience panic disorder in any given year, and many more have isolated panic attacks without meeting the threshold for a disorder. If you’ve had one, you’re not fragile and you’re not broken. Your alarm system misfired. The recovery strategies that work in the short term, controlled breathing, grounding, rest, and gentle movement, also work as daily practices that make your nervous system more resilient over time.
