Can Shortness of Breath Be Caused by Anxiety?
Quick Answer
Yes, anxiety can cause shortness of breath. When you feel anxious, your body's natural "fight or flight" response can lead to rapid breathing (hyperventilation), which may make you feel like you're not getting enough air. This is a common symptom of anxiety and usually isn't dangerous, but it can be very uncomfortable.
How Anxiety Causes Shortness of Breath
Anxiety triggers a cascade of physiological responses designed to prepare your body to react to perceived danger. Here's what happens:
1. The "Fight or Flight" Response
When you feel anxious, your brain sends signals to your nervous system, releasing stress hormones like adrenaline and cortisol. These hormones:
- Increase your heart rate to pump more blood to muscles
- Cause rapid, shallow breathing to take in more oxygen
- Tense your muscles, which can make breathing feel more difficult
2. Hyperventilation
Many people with anxiety breathe too quickly (hyperventilate), which upsets the balance of oxygen and carbon dioxide in your blood. This can cause:
- Dizziness or lightheadedness
- A feeling of not being able to catch your breath
- Chest tightness or pain
- Tingling in your hands or feet
Ironically, these symptoms can make you feel even more anxious, creating a cycle that's hard to break.
3. Muscle Tension
Anxiety often causes muscle tension, especially in the chest and abdomen. Tight muscles can make it harder to take deep breaths, contributing to the feeling of breathlessness.

Other Symptoms of Anxiety
Shortness of breath rarely occurs alone with anxiety. Other common symptoms include:
- Racing heart or heart palpitations
- Excessive sweating
- Trembling or shaking
- Feeling weak or tired
- Trouble concentrating
- Irritability
- Sleep problems
- Gastrointestinal issues (nausea, diarrhea, etc.)
- Feeling a sense of impending doom
If you experience several of these symptoms along with shortness of breath, anxiety may be the cause.
How Common Is This?
Shortness of breath is a very common symptom of anxiety disorders. Studies suggest:
- Up to 45% of people with panic disorder report shortness of breath as a major symptom (NIH).
- About 30% of people who visit the ER for chest pain or breathing difficulties are actually experiencing anxiety or panic attacks (American Heart Association).
- An estimated 40 million adults in the U.S. (18.1% of the population) have an anxiety disorder, many of whom experience physical symptoms like shortness of breath (ADAA).
Differentiating From Other Causes
While anxiety can cause shortness of breath, it's important to rule out other potential causes, especially if this is a new symptom for you. Here's how anxiety-related shortness of breath typically differs from other causes:
Anxiety-Related Shortness of Breath
- Often comes on suddenly during stress or without obvious triggers
- May feel like you can't take a deep breath, or like you're "suffocating"
- Usually improves with calming techniques (deep breathing, distraction, etc.)
- Often accompanied by other anxiety symptoms (racing heart, dizziness, etc.)
- Doesn't typically worsen with physical activity
Other Potential Causes
Shortness of breath can also be caused by:
- Heart conditions (e.g., heart attack, heart failure) - Often accompanied by chest pain, nausea, or pain radiating to the arm/jaw
- Lung conditions (e.g., asthma, COPD, pneumonia) - May include wheezing, coughing, or fever
- Allergies or anaphylaxis - Often includes hives, swelling, or itching
- Anemia - Usually comes on gradually with fatigue and pale skin
Getting a Diagnosis
If you're experiencing shortness of breath, a doctor will likely:
- Take a medical history - They'll ask about your symptoms, when they occur, and any triggers.
- Perform a physical exam - This may include listening to your heart and lungs.
- Order tests if needed - These might include:
- Blood tests (to check for anemia, infection, or heart issues)
- Chest X-ray or CT scan (to look at your lungs and heart)
- EKG or echocardiogram (to check heart function)
- Pulmonary function tests (to assess lung function)
- Evaluate for anxiety - If no physical cause is found, they may screen for anxiety disorders using questionnaires or refer you to a mental health professional.
Treatment Options
If anxiety is causing your shortness of breath, treating the anxiety can help. Options include:
1. Immediate Relief Techniques
- Deep breathing exercises - Try the 4-7-8 method: inhale for 4 seconds, hold for 7, exhale for 8.
- Grounding techniques - Focus on your senses (e.g., name 5 things you see, 4 you feel, etc.).
- Progressive muscle relaxation - Tense and release each muscle group to reduce tension.
2. Lifestyle Changes
- Regular exercise (which can reduce anxiety and improve breathing)
- Healthy diet (limiting caffeine and sugar, which can worsen anxiety)
- Adequate sleep (7-9 hours per night)
- Mindfulness or meditation practices
3. Therapy
- Cognitive Behavioral Therapy (CBT) - Helps change thought patterns that contribute to anxiety.
- Exposure therapy - Gradually facing anxiety triggers in a safe way.
- Biofeedback - Learning to control physiological responses to stress.
4. Medications
In some cases, doctors may prescribe:
- SSRIs or SNRIs (antidepressants that also treat anxiety)
- Benzodiazepines (for short-term relief of severe anxiety)
- Beta-blockers (to control physical symptoms like rapid heartbeat)
Note: Always consult a healthcare provider before starting or stopping any medication.
When It's NOT Anxiety
While anxiety is a common cause of shortness of breath, don't assume it's "just anxiety" without ruling out other possibilities. Seek immediate medical attention if your shortness of breath is accompanied by:
- Chest pain or pressure
- Pain in your arm, jaw, or back
- Nausea or vomiting
- Blue lips or fingers
- High fever
- Wheezing or coughing up blood
- Sudden onset with no obvious trigger
- Worsening symptoms with exertion
These could indicate a serious condition like a heart attack, pulmonary embolism, or severe asthma attack.
When to See a Doctor
Consult a healthcare provider if:
- This is the first time you've experienced shortness of breath
- Your symptoms are severe or worsening
- You have other concerning symptoms (chest pain, dizziness, etc.)
- Your shortness of breath is interfering with daily activities
- You're unsure whether anxiety is the cause
- Self-help techniques aren't providing relief
Key Takeaways
- Anxiety can cause shortness of breath through hyperventilation and the body's stress response.
- It's often accompanied by other symptoms like racing heart, dizziness, or muscle tension.
- Anxiety-related shortness of breath is common, affecting millions of people.
- It typically improves with calming techniques and doesn't worsen with physical activity.
- Always rule out serious causes like heart or lung conditions, especially if symptoms are new or severe.
- Treatment may include breathing exercises, therapy, lifestyle changes, or medications.
- Seek immediate medical help if you have chest pain, blue lips, or other warning signs.
- If anxiety is the cause, effective treatment can significantly reduce or eliminate symptoms.
