Why do panic attacks feel so physical?

A racing heart, chest discomfort, shortness of breath, dizziness, and a sudden feeling that something is seriously wrong can be frightening symptoms to experience. For someone having a panic attack, the intensity of these physical sensations can make it difficult to believe that anxiety alone could be responsible.

Part of what makes panic attacks so frightening is that some of their symptoms can overlap with those associated with physical health problems, including a heart attack. In the moment, trying to figure out what is happening can create even more fear, which may intensify the symptoms.

It is important not to assume that new or unexplained chest symptoms are caused by anxiety. If you think you may be having a heart attack, or you are unsure what is causing your symptoms, seek urgent medical help. The NHS advises calling 999 if you think you or someone else may be having a heart attack.

Once physical causes have been appropriately assessed, understanding how panic affects the body can make these experiences feel less mysterious. Counselling can help people explore patterns of anxiety, recognise triggers and develop ways of responding differently when panic begins.

Why can a panic attack feel life-threatening?

A panic attack involves the body's threat response becoming highly activated. Stress hormones such as adrenaline can contribute to physical changes including a faster heartbeat, quicker breathing and increased alertness.

The sensations can be intense. Someone experiencing panic might notice a racing or pounding heart, chest discomfort, shortness of breath, dizziness, trembling, sweating, tingling sensations or a feeling of unreality.

Because these sensations are physical, they can be extremely convincing. A person may become frightened by what their body is doing, creating a cycle: the sensations cause fear, the fear increases the body's threat response, and the physical sensations become even more noticeable.

Sometimes there is an identifiable trigger, such as a stressful situation, a particular thought or a period of prolonged anxiety. At other times, a panic attack can seem to appear unexpectedly.

Understanding the body's response does not necessarily prevent panic from occurring. However, recognising what may be happening can sometimes make the sensations feel less inexplicable and help reduce the fear of panic itself.

How can you tell a panic attack from a heart attack?

There can be overlap between the symptoms of panic attacks and heart attacks, which is why it is important not to rely on self-diagnosis.

According to the NHS, heart attack symptoms can include chest pain or discomfort that may feel like pressure, heaviness, tightness or squeezing. Pain can also spread to other areas of the body, including the arms, jaw, neck, back or abdomen. Other symptoms may include shortness of breath, sweating, nausea or vomiting, dizziness and an overwhelming feeling of anxiety. The British Heart Foundation (BHF) similarly advises that heart attack symptoms can vary between people and may not always involve severe chest pain.

Panic attacks can also involve chest discomfort, a rapid heartbeat, breathlessness, sweating, dizziness and intense fear. This overlap means there is no simple checklist that can safely determine the cause of symptoms at home.

If chest symptoms are new, unexplained, severe or causing concern, seek medical advice rather than assuming they are anxiety-related. If you think you may be having a heart attack, call 999.

What can help during a panic attack?

If your symptoms have been medically assessed and you recognise that you are experiencing panic, grounding and breathing exercises may help you reconnect with the present moment while the sensations pass.

One commonly used grounding exercise involves deliberately noticing your surroundings:

• five things you can see
• four things you can touch or feel
• three things you can hear
• two things you can smell
• one thing you can taste

The purpose is not to force the panic to disappear. Instead, it gives your attention something concrete to focus on when your mind is becoming increasingly absorbed by frightening thoughts and physical sensations.

Some people also find it helpful to slow their breathing gently. Rather than trying to take very large or rapid breaths, the focus can be on breathing comfortably and allowing the breath to settle.

You might also remind yourself of what you already know about your own panic attacks: that the sensations are uncomfortable, that they have passed before and that you do not have to fight every sensation as it occurs.

Different approaches work for different people, and it can take time to discover what feels most useful.

What if panic attacks keep happening?

Grounding techniques can be useful for managing what is happening during a panic attack, but repeated panic attacks may also be connected to broader patterns of anxiety or stress.

After experiencing a frightening panic attack, some people become highly alert to physical sensations. A change in heartbeat, feeling slightly light-headed or becoming breathless may then trigger the thought that another attack is beginning. This can lead to what is sometimes described as a fear of fear itself.

Someone might start avoiding situations where they previously experienced panic, checking their body repeatedly for symptoms or worrying about what would happen if they had another attack in public.

Over time, anticipating panic can become almost as difficult as the attacks themselves. This is where looking beyond the immediate coping techniques can be helpful.

How counselling can help

Counselling can provide space to explore both the experience of panic and what may be happening around it.

For example, sessions might involve looking at what tends to happen before an attack. You may begin to notice connections with particular situations, periods of stress, thoughts, physical sensations or patterns of avoidance that were not obvious before.

Counselling may also help you explore the thoughts that appear when physical sensations begin. Someone might notice their heart beating quickly and immediately think, something terrible is happening. Exploring that sequence can help make the cycle of panic easier to recognise.

Another area might be anticipatory anxiety. If you have experienced a panic attack while travelling, shopping, working or socialising, you may begin avoiding similar situations because you are frightened it will happen again. Counselling can provide a space to understand how those avoidance patterns developed and how they are affecting everyday life.

For some people, panic occurs during periods of prolonged stress or alongside other difficult experiences. Therapy can offer an opportunity to explore those wider pressures rather than focusing solely on stopping individual attacks.

The aim is not necessarily to guarantee that uncomfortable sensations will never occur again. It may instead be about understanding them better, becoming less frightened of them and developing greater confidence in how you respond.

Understanding what is happening can make a difference

Panic attacks can feel intensely physical, and that is one of the reasons they can be so frightening. Understanding the relationship between anxiety, physical sensations and the body's threat response can help make sense of what is happening.

At the same time, chest pain and other symptoms associated with panic should never automatically be attributed to anxiety. NHS and British Heart Foundation guidance makes clear that heart attack symptoms can vary, and urgent medical help should be sought if a heart attack is suspected.

Once medical concerns have been appropriately addressed, there is support available for recurring panic and anxiety. If panic attacks are becoming frequent, causing significant distress or leading you to avoid parts of everyday life, you may find it helpful to speak with a suitably qualified mental health professional about the support available.
