Pursed lip breathing is an easy-to-learn breathing technique that can significantly aid individuals experiencing shortness of breath and improve lung function. Whether you are coping with a lung condition like COPD or managing anxiety, mastering pursed lip breathing can help slow down your breathing, increase the amount of oxygen you take in, and promote relaxation. This guide explores what pursed lip breathing is, how and when to practice it, its benefits, and essential considerations.
What Is Pursed Lip Breathing?
Pursed lip breathing involves inhaling slowly through the nose and exhaling gently and deliberately through pursed (puckered) lips—similar to whistling or blowing out a candle. This controlled breathing technique increases airway pressure during exhalation, helping keep the airways open longer, releasing trapped air from the lungs, and improving oxygen-carbon dioxide exchange.
Unlike normal breathing, pursed lip breathing emphasizes prolonging the exhalation phase, typically making it twice as long as the inhalation. This active expiration results in positive end-expiratory pressure (PEEP), which counters airway collapse and reduces lung hyperinflation, especially beneficial for individuals with obstructive lung diseases.
How to Perform Pursed Lip Breathing
Follow these simple steps to practice pursed lip breathing effectively:
- Relax your neck and shoulder muscles to ease tension.
- Inhale slowly through your nose for about two seconds, keeping your mouth closed. Focus on allowing your belly to rise as your lungs fill with air.
- Purse your lips loosely, as if preparing to whistle or blow on a hot drink.
- Exhale gently and slowly through your pursed lips for four seconds or longer, ensuring a calm, controlled breath out. Do not force the air out; let it flow naturally.
- Repeat the cycle, continuing until your breathing rate slows and you feel more relaxed.

Practicing this 4-5 times daily for 5 to 10 minutes is ideal until the pattern becomes natural. Over time, you can use pursed lip breathing during physical activity or stressful situations to manage breathlessness.
Who Can Benefit from Pursed Lip Breathing?
While anyone can benefit from learning how to breathe more efficiently, pursed lip breathing provides particular advantages to those with respiratory conditions that affect airway patency and airflow, including:
- Chronic Obstructive Pulmonary Disease (COPD)
- Asthma
- Pulmonary fibrosis
- Other chronic lung diseases causing airway obstruction or breathlessness
Additionally, pursed lip breathing can help individuals experiencing anxiety and stress by promoting relaxation and bringing focus to breathing.
Why Use Pursed Lip Breathing?
Pursed lip breathing helps by:
- Slowing your breathing rate, which reduces the effort required to breathe.
- Keeping airways open longer, preventing premature airway collapse.
- Releasing trapped air in the lungs, improving ventilation efficiency.
- Improving oxygen intake and carbon dioxide removal, helping balance blood gases.
- Reducing breathlessness during activity or at rest.
- Promoting relaxation and reducing stress or anxiety symptoms.
For people with COPD and other obstructive lung diseases, pursed lip breathing serves as a compensatory mechanism that creates positive pressure within the airways, preventing collapse and reducing air trapping which often causes dyspnea and fatigue.
When to Practice Pursed Lip Breathing
You can practice pursed lip breathing:
- During physical activity, such as walking, climbing stairs, lifting, or exercising, particularly when you start to feel short of breath.
- At rest or during stressful situations such as reading, sitting quietly, or waiting in line, to develop ease and control with the technique.
- When managing anxiety or feelings of panic, as the slow and deliberate breaths promote calmness.
Regular practice when not symptomatic ensures you can apply pursed lip breathing effectively when needed.
Important Considerations and Precautions
- Proper technique is essential: Incorrect or forced breathing may worsen symptoms or cause dizziness.
- If you experience dizziness, light-headedness, or fatigue, stop and rest.
- Pursed lip breathing does not cure lung diseases but provides symptomatic relief and helps improve breathing efficiency.
- If breathlessness worsens or does not improve after practicing pursed lip breathing, seek medical help immediately.
- For certain lung conditions like interstitial lung disease, pursed lip breathing may not improve exercise tolerance and should be used under guidance.
Differences Between Pursed Lip and Belly Breathing
Pursed lip breathing focuses on prolonging exhalation through puckered lips, creating airway pressure to support airflow. Belly breathing, or diaphragmatic breathing, encourages engaging the diaphragm muscle to take fuller, deeper breaths. While both techniques aid breathing, pursed lip breathing is simpler and easier to learn and especially effective for managing airflow limitations.
Summary
Pursed lip breathing is a simple, accessible technique that can help anyone improve breathing efficiency, ease breathlessness, and reduce anxiety. By slowing the breathing rate and keeping airways open longer, this technique supports better oxygen exchange and lung function, particularly benefiting those with pulmonary conditions such as COPD and asthma. With regular practice, pursed lip breathing can become a valuable tool for managing respiratory symptoms and enhancing overall well-being.
