Panic Attack vs Anxiety Attack: Symptoms, Differences, What to Do

A panic attack is a sudden surge of intense fear with strong physical symptoms, such as a pounding heart, shortness of breath, trembling or chest pain, that often comes out of nowhere and peaks within minutes. An "anxiety attack" is not a medical diagnosis. People use the phrase for a period of high anxiety that usually builds more gradually in response to a stressor, such as a deadline, an argument or a health worry, and that is often less intense but can last longer.

The difference matters because panic attacks are a defined clinical event, they can be the core of panic disorder, and there are specific, well-studied treatments for them. Both experiences are real and distressing, and neither is a sign of weakness. This guide compares the two side by side, explains what each feels like, what to do in the moment, how to tell a panic attack from a heart problem, and when to get help.

Panic attack vs anxiety attack at a glance

	Panic attack	"Anxiety attack" (high anxiety)
Medical term?	Yes; described in the DSM-5-TR, the diagnostic manual U.S. clinicians use	No; an everyday phrase, not a diagnosis
How it starts	Suddenly, often without a clear trigger, sometimes even during sleep	Usually builds over minutes to hours, often tied to a worry or stressor
Intensity	Intense fear or discomfort, a sense of losing control or doom	Ranges from mild to severe; more often tension, worry and restlessness
Physical symptoms	Strong: racing heart, chest pain, shortness of breath, dizziness, trembling, tingling, sweating, nausea	Present but usually milder: muscle tension, fast heartbeat, stomach upset, trouble sleeping
How long	Usually peaks within minutes; NIMH says an attack can last "from a few minutes to an hour or sometimes longer"	Can last hours or come and go over days while the stressor continues
Afterward	Often fear of the next attack and avoiding places where one happened	Worry often eases when the stressor passes
Linked conditions	Panic disorder; can also occur with other anxiety disorders, depression or PTSD	Generalized anxiety disorder, social anxiety, stress, many others

What a panic attack is

The National Institute of Mental Health (NIMH) describes a panic attack as "a sudden wave of fear or discomfort or a sense of losing control," often when there is no clear danger. Clinicians use the DSM-5-TR definition: an abrupt surge of intense fear or discomfort that reaches a peak within minutes, with at least four physical or mental symptoms from a list that includes a pounding heart, sweating, trembling, shortness of breath, a choking feeling, chest pain, nausea, dizziness, chills or heat sensations, numbness or tingling, feeling detached from oneself or one's surroundings, fear of losing control, and fear of dying.

Panic attacks can be expected, set off by something the person fears, such as flying or crowded places, or unexpected, appearing with no obvious cause. A single panic attack, or an occasional one, is not a mental disorder. NIMH notes that "not everyone who experiences a panic attack will develop panic disorder."

Panic attack symptoms

NIMH lists these common symptoms:

• Racing or pounding heart
• Sweating, chills or trembling
• Shortness of breath
• Dizziness or weakness
• Tingling or numbness in the hands
• Chest pain
• Stomach upset or nausea
• A sense of doom or fear of death
• A sense of losing control

Because the physical symptoms are so strong, many people's first panic attack ends in an emergency room, convinced they are having a heart attack. That is a reasonable reaction; see the section on telling them apart below.

What people mean by an "anxiety attack"

When someone says they had an anxiety attack, they usually mean a stretch of intense worry, tension and physical stress that built up around something specific: a job interview, a medical test, a fight with a partner, money trouble. The body's stress response is the same one involved in panic, so the symptoms overlap: a fast heartbeat, tight muscles, an upset stomach, restlessness, trouble concentrating or sleeping.

The differences are mostly in onset, intensity and duration. High anxiety tends to rise gradually, stay at a lower peak and last longer, while a panic attack hits fast and hard and then subsides. Some people use "anxiety attack" for what is actually a panic attack, which is why clinicians ask about the details: how fast it started, how strong the physical symptoms were and how long it lasted.

Common signs of high anxiety

• Persistent worry that is hard to switch off
• Feeling keyed up, restless or on edge
• Muscle tension, headaches, jaw clenching
• Fast heartbeat or shallow breathing
• Stomach upset, nausea or diarrhea
• Irritability and trouble concentrating
• Trouble falling or staying asleep

Two examples side by side

A panic attack

Maria is standing in line at the grocery store on an ordinary Tuesday. Without warning her heart starts pounding, her chest tightens, her hands tingle and she feels as if she cannot get enough air. Within a few minutes she is sure she is about to faint or die. She leaves her cart and sits in her car. Over the next twenty minutes the symptoms fade, leaving her exhausted and shaken, and for weeks she avoids that store. Sudden onset, a fast peak, intense physical symptoms, no clear trigger and fear of the next attack are the hallmarks of panic.

High anxiety ("anxiety attack")

James has a performance review on Friday. From Wednesday on he sleeps badly, his shoulders ache, his stomach is upset and he cannot stop replaying what his manager might say. Thursday evening his heart races and he feels on the verge of tears. The feeling rises and falls for two days and eases after the meeting. The trigger is clear, the build-up is gradual and the intensity, though miserable, stays below the sudden terror of a panic attack.

Both experiences deserve attention. If either pattern repeats, a doctor or therapist can help sort out what is going on.

Panic disorder: when panic attacks keep coming

NIMH describes panic disorder as recurrent, unexpected panic attacks followed by ongoing worry about having more attacks, or by changes in behavior to avoid them, such as skipping places or situations where an attack happened before. Those changes "often interfere with daily life." Panic disorder often begins in the late teens or early adulthood, sometimes runs in families, and is more common in women than in men, according to NIMH.

Some people with panic disorder start avoiding more and more places, such as stores, public transit, highways or crowds, because they fear having an attack where escape or help would be difficult. That pattern, called agoraphobia, can shrink a person's world, which is one reason early treatment helps.

Panic attacks during sleep

Some panic attacks happen at night and wake a person from sleep, often called nocturnal panic attacks. The person wakes suddenly with a racing heart, sweating, shortness of breath and a sense of terror, without a frightening dream to explain it. They are not the same as nightmares, which are remembered dreams, or night terrors, which are more common in children and usually not remembered.

Nighttime attacks can be especially frightening because there is no obvious trigger. Because other conditions can also wake people with a racing heart or gasping, such as sleep apnea, reflux or heart rhythm problems, repeated nighttime episodes are worth discussing with a doctor.

What to do during a panic attack

These steps are commonly taught by therapists. They do not stop every attack, but they can make the peak shorter and less frightening.

1. Name it. If you have had panic attacks before and your doctor has ruled out other causes, tell yourself: "This is a panic attack. It is frightening, but it will pass." NIMH notes that "panic attacks themselves are not life-threatening."
2. Slow your breathing. Breathe in through the nose for about four counts, hold briefly, and breathe out slowly through the mouth for about six counts. A longer out-breath helps counter over-breathing, which can cause tingling and dizziness.
3. Ground yourself. The 5-4-3-2-1 exercise: name five things you can see, four you can touch, three you can hear, two you can smell and one you can taste.
4. Do not fight the sensations. Trying to force symptoms away tends to increase fear. Let them rise and fall like a wave.
5. Stay where you are if you can. Leaving every time teaches the brain the place is dangerous. If you need to move, walk slowly.
6. Afterward, note what happened. Time, place, what you were doing and how long it lasted. This helps you and a clinician see patterns.

How to help someone having a panic attack

• Stay calm and stay with them. Speak in short, simple sentences.
• Ask if they have had panic attacks before and whether something usually helps.
• Breathe slowly with them; count out loud.
• Do not say "calm down" or "it's nothing." Say "I'm here. This will pass."
• If they have chest pain, trouble breathing that does not improve, fainting, or this is their first episode, call 911.

What to do when anxiety is building

• Name the worry. Write down exactly what you are anxious about and what, if anything, you can do about it today.
• Move. A brisk 10-minute walk uses up some of the stress response.
• Cut stimulants. Caffeine and nicotine can make physical anxiety symptoms stronger.
• Limit the loop. Set a fixed "worry time" of 15 minutes and postpone worry outside it.
• Talk to someone. A friend, family member, pastor or counselor.
• Protect sleep. Regular sleep and wake times make anxiety easier to manage.

Some people find comfort in prayer or Scripture when anxious; our page of Bible verses about anxiety collects them.

Panic attack or heart attack?

Chest pain, shortness of breath, sweating, dizziness and a racing heart can be signs of a heart attack as well as panic. You cannot reliably tell them apart on your own, especially the first time. The National Heart, Lung, and Blood Institute lists these heart attack warning signs:

• Chest pain, heaviness or discomfort in the center or left side of the chest
• Pain or discomfort in one or both arms, the back, shoulders, neck, jaw or above the belly button
• Shortness of breath at rest or with little activity
• Sweating a lot for no reason
• Feeling unusually tired for no reason, sometimes for days (more common in women)
• Nausea and vomiting
• Light-headedness or sudden dizziness
• Rapid or irregular heartbeat

NHLBI's advice is clear: call 911 "even if you are not sure that you're having a heart attack," because "every minute matters," and do not drive yourself or let someone else drive you to the hospital. Being checked and told it was panic is far better than staying home with a heart attack. More on telling physical anxiety symptoms apart is in anxiety chest tightness.

Treatment for panic attacks and anxiety

Both panic disorder and anxiety disorders are treatable. NIMH describes two main approaches:

Treatment	What it involves
Cognitive behavioral therapy (CBT)	The most studied psychotherapy for panic. It teaches different ways of thinking about and reacting to the sensations of panic, and often includes exposure, including interoceptive exposure (safely bringing on sensations like a fast heartbeat so they become less frightening). Available in person or by telehealth.
SSRIs and SNRIs	Antidepressants commonly prescribed for panic disorder and other anxiety disorders; they take several weeks to work.
Beta-blockers	Can help some physical symptoms such as a rapid heartbeat.
Benzodiazepines	Can act quickly, but may cause tolerance or dependence, so they are usually prescribed for short periods.

A primary care doctor is a good first stop: they can check for medical causes, such as thyroid problems, heart rhythm issues or medication side effects, and refer you to a therapist or psychiatrist.

When to get help

• Call 911 for chest pain or pressure, trouble breathing, fainting, or symptoms that do not ease, especially if this is the first time.
• Call or text 988, the Suicide & Crisis Lifeline, any time if you have thoughts of harming yourself or feel you cannot cope.
• See a doctor soon if panic attacks repeat, if you avoid places because of them, if worry is constant, or if anxiety affects work, school, sleep or relationships.
