An anxiety attack typically produces a combination of intense physical and psychological symptoms that peak within minutes and can last up to an hour. The most common signs include a racing heart, chest pain, shortness of breath, trembling, sweating, dizziness, and a feeling of losing control. About 4.7% of U.S. adults will experience these episodes at some point in their lives.
Physical Symptoms
The physical side of an anxiety attack is often what alarms people most, because the symptoms feel like a medical emergency. Your heart pounds or races. You may shake, sweat, or feel chills and hot flashes cycling through your body. Breathing becomes difficult, with tightness in the throat or a sensation of being smothered. Many people hyperventilate without realizing it, which makes other symptoms worse.
Chest pain is extremely common and is one of the main reasons people end up in the emergency room during an attack. Nausea, abdominal cramping, and dizziness or lightheadedness round out the picture. Some people feel numbness or tingling in their fingers, toes, or face. This tingling is typically caused by the changes in blood chemistry that happen when you breathe too fast.
Psychological Symptoms
Alongside the physical sensations, anxiety attacks produce a distinct set of mental and emotional experiences. A sudden, overwhelming sense of dread or doom is one of the hallmarks. You may feel certain that something catastrophic is about to happen, even when there’s no apparent threat.
Some people experience depersonalization, which feels like being disconnected from your own body, thoughts, and feelings. It can seem as though you’re watching yourself from outside, like observing a character in a movie. Others experience derealization, where your surroundings look distorted, foggy, or dreamlike. Objects might appear to change shape or size. These sensations are disorienting but temporary, and they don’t mean you’re losing your mind. They’re a side effect of your nervous system being in overdrive.
Fear of losing control, going crazy, or dying is also common during an attack. These fears feel absolutely real in the moment, which is part of what makes the experience so distressing.
Why Your Body Reacts This Way
Every symptom of an anxiety attack traces back to your body’s fight-or-flight system firing when there’s no actual danger. It starts in a part of the brain that processes threats. When this area perceives danger (real or not), it sends an alarm signal to the hypothalamus, which acts as a command center. The hypothalamus activates your sympathetic nervous system, which triggers the adrenal glands to pump adrenaline into your bloodstream.
That adrenaline surge is responsible for the racing heart, rapid breathing, sweating, and muscle tension. If the brain keeps perceiving a threat, a second hormonal system kicks in and releases cortisol, the body’s main stress hormone. This keeps your system on high alert even after the initial adrenaline rush fades. The whole cascade explains why symptoms can feel so intense and so physical. Your body is genuinely preparing to fight or flee, even though there’s nothing to fight or flee from.
How Long an Attack Lasts
Most anxiety attacks peak within about 10 minutes. The worst of the symptoms, the chest pain, racing heart, and sense of terror, tend to concentrate in that window. After the peak, symptoms gradually taper off. The entire episode usually resolves within a few minutes to an hour.
What many people don’t expect is what comes afterward. The “panic attack hangover” can linger for hours or even days. Your body flooded itself with stress hormones during the attack, and as those levels crash, you’re left feeling physically drained, foggy, and sometimes achy. Muscle soreness in the neck, shoulders, and back is common from all the tension. Some people feel emotionally numb or detached, while others feel irritable and on edge. A lingering sense of vulnerability, or embarrassment about the episode, is also normal.
Anxiety Attack vs. Heart Attack
Because chest pain and a pounding heart are central to both, many people experiencing an anxiety attack genuinely believe they’re having a heart attack. There are a few practical differences worth knowing.
- Type of chest pain: Anxiety attacks tend to produce sharp or stabbing chest pain. Heart attacks feel more like pressure, squeezing, or a burning sensation.
- Where the pain spreads: During a heart attack, pain often radiates to the arm, jaw, or neck. With an anxiety attack, it usually stays in the chest.
- What triggered it: Heart attacks tend to follow physical exertion, like shoveling snow or climbing stairs. Anxiety attacks are linked to emotional stress or can come out of nowhere.
- How it resolves: Anxiety attack symptoms peak and then fade within an hour. Heart attack pain persists or comes in waves, getting better and worse but not fully going away.
One other clue: people who have nighttime anxiety attacks almost always have daytime attacks too. If you wake up with chest pain and have no history of anxiety attacks, that’s a stronger signal to treat it as a potential cardiac event.
What Helps During an Attack
Grounding techniques can interrupt the cycle of panic by pulling your attention out of your body and into the present moment. One widely used approach is the 5-4-3-2-1 technique: name five things you can see, four you can touch, three you can hear, two you can smell, and one you can taste. This works by giving your brain a concrete task that competes with the fear signals.
Controlled breathing is the other front-line tool. Box breathing (inhale for four counts, hold for four, exhale for four, hold for four) helps counteract hyperventilation and slows the adrenaline response. The 4-7-8 method, where you inhale for four counts, hold for seven, and exhale for eight, has a similar effect. Both techniques activate the parasympathetic nervous system, which is essentially the brakes on your fight-or-flight response.
Reminding yourself that the symptoms are temporary and not dangerous is also effective, even if it doesn’t feel convincing in the moment. The more you practice recognizing an attack for what it is, the less power the fear-of-the-symptoms cycle has over you. If attacks are happening repeatedly or are disrupting your daily life, that pattern has a name (panic disorder) and responds well to treatment.
