What to know

1

A panic attack is an intense, internal stress response that passes quickly, but the “panic attack hangover” that follows can linger for hours or even days.

2

Recovery in the first few hours after a panic attack focuses on calming your nervous system, while recovery over the following days often focuses on finding more balance.

3

For many people, working with a licensed therapist or psychiatric provider can make panic attacks less frequent and less intense.

Introduction

The panic attack is over. Your heart has slowed, your breathing has evened out, and the wave of fear has passed. But your body may not feel like your own yet.

That in-between stretch is what most people mean when they ask what to do after a panic attack. Plenty of them call it a panic attack hangover: the hours or days when you feel foggy, sore, and wrung out even though the worst is behind you. It's a real physical response, and learning effective stress management along with concrete recovery steps can help soothe your body and bring comfort as you settle down.

What is a panic attack?

A panic attack is a sudden rush of intense fear or discomfort that peaks within minutes, along with strong physical symptoms: a pounding heart, shortness of breath, sweating, trembling, nausea, or a sense of being detached from your surroundings. It can arrive with no clear trigger, including when you're calm.

Anik Saha, MD, a board certified psychiatrist and associate medical director of clinical product at Headway, says, “Panic attacks can come from specific triggers or out of nowhere. They involve a surge in the sympathetic nervous system, releasing stress hormones like adrenaline and cortisol. Heart rate and blood pressure go up, blood is diverted away from digestion and toward your muscles, and your body mobilizes energy to gear up for that fight or flight response. Alongside the physical symptoms, there’s often an intense sense of fear or doom, or a feeling that you’re losing control or that something terrible is about to happen.”

One attack in and of itself is not a diagnosis. Panic disorder is. The DSM-5-TR (the manual clinicians use for mental health diagnoses) describes it as repeated, unexpected attacks plus a month or more of worry about the next one, or changes in behavior meant to avoid one. Attacks can also show up alongside other conditions, including depression, anxiety, and post-traumatic stress, which a mental health professional can explore with someone who’s experiencing panic attacks.

What is a panic attack hangover?

A panic attack hangover is the physical and emotional aftermath that sticks around once the attack ends. “Panic attack hangover” isn't a clinical term; it's a colloquial term for the come-down, but it describes something very real.

A panic attack sets off your sympathetic nervous system's fight-or-flight response, flooding your bloodstream with stress hormones. Your heart speeds up, your muscles tense, and blood shifts toward your limbs. Your body mobilizes for an emergency that never arrives.

Then the alarm shuts off, and all of it has to come back down. Adrenaline drops, and your parasympathetic nervous system slows. That recalibration is the hangover, which is why the aftermath can outlast the attack and why stress hormones take time to settle. If your body seems to stay stuck in that dysregulated state between attacks, that's worth paying attention to.

“You can think of your sympathetic nervous system as the body’s accelerator. It drives your body’s fight or flight response, increasing heart rate and blood pressure,” says Saha. “The parasympathetic nervous system is like the brakes — it slows heart rate, directs blood towards the digestive system, and supports your body’s ‘rest and digest’ functions.”

Panic attack hangover symptoms

Panic attack hangover symptoms vary from one person, and one attack, to the next. Factors like culture, upbringing, and circumstance can also affect how panic shows up for each individual. But most people notice that a panic attack feels like a mix of these symptoms in the days or hours afterward:

  • Deep fatigue that doesn't lift with rest
  • Brain fog, or a sense that the world feels slightly unreal
  • Sore muscles, especially in the jaw, neck, shoulders, and chest
  • Shakiness or trembling
  • Chest discomfort or tightness
  • Dizziness or lightheadedness
  • Nausea or an unsettled stomach
  • Emotional rawness, tearfulness, irritability, numbness, or lingering fear of another attack

Some of these symptoms overlap with heart problems. Chest pain, shortness of breath, dizziness, and trembling can all signal a cardiac event, and it's very hard to tell the difference on your own. Call 911 if you aren't sure, especially with chest pain. If it turns out to be a panic attack, calling was still the right thing to do — clinicians would much rather rule out a heart problem than miss one.

“After an attack, when adrenaline and cortisol start coming down in the body, your nervous system remains sensitized for some time. It can be a draining experience, and it’s common to feel foggy and fatigued. As with any time you’ve had a really stressful experience, panic attacks use a lot of energy from your body,” says Saha.

Attacks that keep happening, get more intense, or start shaping how you spend your days are worth bringing to a licensed mental health professional.

How to recover from a panic attack

Healthy coping skills are key in bouncing back from a panic attack. Recovery runs on two clocks: the first hour, when the goal is to help your body come down safely, and the next few days, when it's about room to reset. Here's how to recover from a panic attack on both.

Physical care

You may want to treat the hours after a panic attack the way you'd treat the hours after a stomach bug: Find a quiet place to sit, lie down, and drink water, since fast breathing, sweating, and crying all leave you dehydrated. Consider eating something small with protein in it, which can help if you're shaky or lightheaded. Splashing cool water on your face or listening to calm music can help steady your nervous system. It can also help to ease off coffee, energy drinks, and nicotine for the rest of the day, since stimulants produce the same sensations panic feeds on. Gentle movement tends to do more than rest alone: Try rolling your shoulders, unclenching your jaw, or going on a slow walk around the block.

Saha says, “Stimulants like nicotine and coffee increase heart rate, which can serve as a cue to the brain that something dangerous is about to happen — similar to the sensations experienced during a panic attack. Especially after a panic attack, we want to reduce those sensations so you can recover, so it helps to ease off nicotine and caffeine for the rest of the day. What helps is rest or a walk outside to use up that excess adrenaline. I’d also recommend a small snack to restore your blood sugar. Water, decaf, or caffeine-free herbal tea are good alternatives to stimulants.”

Breathing and grounding techniques

A systematic review in Frontiers in Human Neuroscience found that breathing at fewer than ten breaths per minute shifts the body toward parasympathetic activity, and is linked to less tension and better mood.

One effective relaxation technique is box breathing: Inhale slowly for four seconds, hold your breath for four seconds, exhale for four seconds, and hold empty for four seconds. Repeating this cycle or taking time to deep breathe for two or three minutes can make a big difference in helping your body reset.

“Breathing exercises such as diaphragmatic breathing and box breathing can help engage the vagus nerve and the parasympathetic system, which helps your body return to a calm state after a panic attack. If focusing on your breath feels uncomfortable, try a grounding exercise or gentle movement instead,” says Saha.

If your mind is still spinning, trying a sensory grounding technique can help bring your focus back to the present moment. A common practice is the 5-4-3-2-1 method: name five things you can see around you, four things you can physically touch, three things you hear, two things you can smell, and one thing you can taste. Some people find cold water on the face works too, since a sharp temperature change gives the nervous system a clear signal.

Journaling

A written record can give the experience edges. You may want to note when the attack started, what was happening around you, what you felt in your body, and how long the aftermath lasted. Over a few weeks, patterns sometimes surface that are hard to see in the moment. That record is also useful to hand to a therapist, and worth keeping somewhere private in the meantime. If a blank page feels like too much, a few starter prompts can get you moving.

Reaching out for support

You can ask for help without explaining the whole thing. You might tell one person you trust: "I had a panic attack and I'd rather not be by myself right now." Many people find it helps to be near someone calm. A therapist or psychiatric provider is worth considering too, especially if it feels like you’re living with severe anxiety.

FAQs about panic attacks

Can panic attacks last for days?

No. The surge peaks within minutes and usually eases within half an hour, so what stretches across days is the hangover or ongoing anxiety rather than the attack. If it feels like you've been mid-attack for days, contact a medical doctor to assess what may be going on for you.

Can a panic attack happen during sleep?

Yes. Nocturnal panic wakes you from sleep already in a state of panic, and a review in Sleep Medicine Reviews found that 44% to 71% of people with panic disorder report at least one. It's a non-REM event, and clinicians treat it as separate from nightmares, night terrors, and sleep apnea.

Is it normal to feel embarrassed or confused after a panic attack?

Yes, and it's very common. Panic attacks can look dramatic from the outside and feel disorienting from the inside. But the embarrassment usually fades faster than the physical panic symptoms — and panic disorder is nothing to be ashamed of.

How long does a panic attack hangover last?

Most people feel more like themselves within a day, though fatigue and brain fog can stretch across two or three days after a severe attack.

Does anything make the hangover worse?

Short sleep, skipped meals, and alcohol often drag it out, since each one adds strain to a nervous system that's still recalibrating. Many people also feel it if they power through a full day as if nothing happened.

How therapy helps

Therapy can help you shift your thoughts about panic attacks from something that happens to you into something your body might be trying to tell you. Cognitive behavioral therapy (CBT) is the most studied approach: a Cochrane network meta-analysis of randomized trials in adults with panic disorder ranked it among the psychological therapies with the strongest evidence for remission. In a session with a therapist, that tends to look like learning to reread the sensations that spiral into panic, then building tolerance for them instead of trying to steer around them.

Some people also work with a psychiatrist or psychiatric nurse practitioner to get medication, on its own or alongside therapy. What fits depends on your symptoms, your history, and what works for you.
