Can stress cause chest pain or discomfort? What to know, and when to worry

A deadline, an argument, a hard week, and suddenly your chest feels tight, sore or heavy. It’s a common experience, and it’s natural to wonder whether stress is really to blame, or whether something is wrong with your heart.

Here’s how stress causes chest discomfort, when it can affect your heart, and what helps.

Call 911 (or your local emergency number) now if you have chest pain or tightness that came on suddenly, lasts more than a few minutes, or spreads to your arm, neck, jaw or back, especially with breathlessness, sweating, nausea or feeling faint. Don’t assume it’s stress.

Can stress cause chest pain?

Yes. Stress switches on your body’s fight-or-flight response, which can cause chest discomfort in several ways:

• Muscle tension. Stress braces the muscles in your chest, shoulders and upper back. They can ache, feel tight or be sore to touch, sometimes for days.
• Breathing changes. Under stress you often breathe faster and higher in your chest, which overworks chest muscles and can make your chest feel tight.
• A pounding heart. Adrenaline makes your heart beat harder and faster, and you notice it more.
• Acid reflux. Stress, rushed meals, extra coffee and alcohol can all bring on heartburn, which can feel like burning or tightness behind your breastbone.
• Clenching and posture. Hunching over a desk or phone while stressed adds to tension in your chest and shoulders.

What stress-related chest discomfort feels like

• a tight band or pressure across your chest
• aching or soreness, sometimes in one spot
• sharp, brief twinges
• burning behind your breastbone, especially after eating
• feeling you can’t take a full breath

It often comes with other signs of stress, like tense shoulders, headaches, poor sleep and irritability, and eases when the pressure lifts.

When stress can affect your heart

Most stress-related chest discomfort comes from muscles, breathing and digestion. But stress can affect the heart too:

• Intense stress can trigger heart problems in people who already have heart disease, including angina and heart attacks.
• Takotsubo syndrome, sometimes called “broken heart syndrome”, is a temporary weakening of the heart muscle that can follow sudden, intense emotional or physical stress, like a bereavement or a shock. It causes symptoms like a heart attack, such as chest pain and breathlessness, and needs emergency care. It’s most common in women after menopause. An international expert consensus has noted it can lead to serious complications.

That’s why it’s important not to assume chest pain is “just stress”, especially if it’s new or severe.

When to get help

Call 911 (or your local emergency number) if you have:

• chest pain, pressure or tightness that came on suddenly or lasts more than a few minutes
• pain that spreads to your arms, neck, jaw, back or stomach
• chest pain with breathlessness, sweating, nausea or light-headedness
• sudden severe pain that feels like tearing
• fainting

See a doctor soon if:

• you get chest discomfort when you exert yourself that eases with rest
• chest discomfort keeps coming back during stressful times
• you have heartburn most days
• you have risk factors for heart disease, like high blood pressure, diabetes, high cholesterol, smoking or a family history

What helps stress-related chest discomfort

In the moment:

1. Breathe out slowly. In for 4, out for 6, for a few minutes.
2. Drop your shoulders and unclench your jaw.
3. Open your chest: sit tall and gently stretch your arms wide.
4. Use warmth, like a warm shower or heat pack on your chest or upper back.
5. Step away from the stressful situation for a few minutes if you can, and take a short walk.

Over time:

• Tackle the source where possible: workload, boundaries, asking for help.
• Move regularly, which eases muscle tension and stress.
• Protect your sleep.
• Go easy on caffeine and alcohol, and avoid big meals late at night if reflux is part of it.
• Practise a daily calming skill, like slow breathing.
• Get support if stress is turning into ongoing anxiety. Our post on stress vs anxiety explains the difference.

Frequently asked questions

Can stress make your chest hurt for days?

Yes. Tense chest and shoulder muscles can stay sore for days during a stressful period. But chest pain that lasts days should be checked by a doctor, to rule out other causes.

Where do you feel stress chest pain?

Anywhere in the chest. Many people feel it in the centre or on the left side, which is especially worrying. Location alone can’t tell you whether it’s stress or your heart.

Is stress chest pain different from anxiety chest pain?

They work the same way and feel the same. Stress usually has a clear cause, like a deadline, while anxiety can carry on after the stress has passed. Our post on whether anxiety can cause chest pain covers anxiety specifically.

Can stress cause a heart attack?

Intense stress can trigger a heart attack in people who already have heart disease, and sudden severe stress can cause takotsubo syndrome. That’s why sudden or severe chest pain always needs urgent help, whatever you think the cause is.
