Pursed lip breathing and diaphragmatic breathing are the two most effective breathing exercises for COPD, and both can be done anywhere without equipment. They work by keeping your airways open longer during exhalation, which is the core problem in COPD: air gets trapped in your lungs because the small airways collapse before you finish breathing out. A few additional techniques round out a solid daily routine, especially for clearing mucus and staying active.
Pursed Lip Breathing
This is the single most recommended breathing exercise for COPD, and it works immediately. When you exhale through pursed lips, you create a small amount of back-pressure that travels from your mouth down into your lower airways. That pressure acts like an internal splint, preventing your bronchial tubes from collapsing during exhalation. The result: more stale, carbon dioxide-rich air actually leaves your lungs, making room for fresh air on the next breath.
Here’s how to do it:
- Breathe in through your nose. The breath can be deep or shallow.
- Hold for one or two seconds.
- Purse your lips like you’re blowing out a candle.
- Exhale slowly and gently for four to five seconds.
- Continue for four to five minutes, or until your shortness of breath eases.
Pursed lip breathing is especially useful during physical activity. If you get winded while walking, climbing stairs, or doing housework, stop and use this technique until your breathing settles. Many people with COPD learn to exhale through pursed lips automatically during any exertion.
Diaphragmatic Breathing
Your diaphragm is the large dome-shaped muscle beneath your lungs that does most of the work of breathing. In COPD, trapped air pushes the diaphragm down and flattens it, making it less efficient. Your neck and chest muscles start compensating, which is tiring and less effective. Diaphragmatic breathing retrains you to use that main muscle properly.
Start lying down, since it’s easier to feel your diaphragm working in that position. Lie on your back with your knees bent and your head supported. Place one hand on your upper chest and the other just below your rib cage. Breathe in through your nose and focus on pushing your belly outward so the lower hand rises. The hand on your chest should stay as still as possible. Then tighten your stomach muscles and exhale through pursed lips, feeling the lower hand sink back down.
Once you’re comfortable lying down, practice while sitting in a chair with your knees bent and your shoulders relaxed, using the same hand positions. The goal is to eventually use this breathing pattern throughout the day without thinking about it. Most pulmonary rehabilitation programs suggest practicing at least a few times daily, gradually working up from short sessions.
Huff Coughing for Mucus Clearance
A regular forceful cough can actually make things worse in COPD. The sudden pressure causes your airways to narrow and collapse, trapping the mucus you’re trying to move. A huff cough uses controlled, moderate force to move mucus without slamming your airways shut. Think of it as fogging up a mirror: smaller, more deliberate exhales rather than one explosive cough.
To do it, sit on a chair or the edge of your bed with both feet on the floor. Tilt your chin up slightly and open your mouth. Take a breath in and hold it for two to three seconds. This gets air behind the mucus. Then exhale slowly but firmly, like you’re steaming up a window. That moves mucus from your smaller airways into the larger ones. Repeat one or two more times, then finish with one strong cough to clear the mucus from the larger airways. You can repeat the whole cycle two or three times depending on how congested you feel.
One important detail: don’t gasp in quickly after coughing. Quick, deep breaths can push mucus back down and trigger uncontrolled coughing. Breathe in gently between rounds. Try this technique after using your bronchodilator medication, when your airways are most open.
Three-Part Breathing
This yoga-based technique, called Dirgha breathing, takes diaphragmatic breathing a step further by filling your lungs in three stages. A randomized trial in people with COPD found that 12 weeks of practice led to a 28-meter increase in six-minute walking distance, along with small improvements in how much air participants could inhale and reductions in air trapping.
While sitting in a chair, breathe in slowly through your nose. First fill the bottom of your lungs (your belly expands), then the middle (your ribs widen), then the top (your upper chest lifts slightly). Exhale in whatever order feels natural, either bottom-to-top or top-to-bottom, through your nose or mouth. There’s no required speed or count. The emphasis is on slow, complete breaths that encourage your lungs to empty more fully, which is one of the biggest challenges in COPD.
Inspiratory Muscle Training
If your breathing muscles are particularly weak, a handheld device can add resistance training to your routine. These devices make you inhale against a set resistance, strengthening the muscles you use to draw in air. Three types exist: threshold devices that use a spring-loaded valve, resistive devices with adjustable hole sizes, and hyperpnea devices that increase your breathing rate. Threshold devices are the most commonly used in rehabilitation programs.
To be effective, the resistance needs to be set above 30% of your maximum inspiratory pressure, which your doctor or respiratory therapist can measure. The Spanish Society of Pneumology and Thoracic Surgery recommends inspiratory muscle training specifically for patients with inspiratory muscle weakness, defined as a maximum inspiratory pressure below 60 cmH2O. This isn’t something to start on your own. A respiratory therapist can test your baseline strength, set the right resistance, and adjust it as you improve.
How Long Before You Notice Results
Pursed lip breathing provides relief in the moment, reducing breathlessness within minutes. The longer-term benefits of a daily breathing exercise routine take more time. A Cochrane review of multiple trials found that consistent practice over four to 15 weeks improved functional exercise capacity compared to no intervention. However, the effects on breathlessness and quality of life varied across studies, meaning some people experience significant relief while others see more modest changes.
In one 10-week program, participants who practiced regularly saw their perceived breathlessness after exercise drop from 3.05 to 2.54 on a standard scale, while a control group barely changed. Their anxiety about breathing during exercise also decreased, and their ability to perform daily activities improved. The takeaway: stick with the exercises for at least several weeks before judging whether they’re helping, and focus on consistency rather than marathon sessions.
When to Stop and Rest
Breathing exercises are low-risk, but COPD means your respiratory system has less margin for error. Stop immediately if you experience chest pain, dizziness or lightheadedness, a rapid or irregular heartbeat, worsening shortness of breath that doesn’t improve with pursed lip breathing, or if you cough up unusual fluids. These are signs that something beyond normal exertion is happening and need medical attention.
If you’re new to breathing exercises, start with pursed lip breathing and basic diaphragmatic breathing before layering on other techniques. Once those feel natural, add huff coughing for mucus management and three-part breathing for deeper lung engagement. Building your routine gradually gives you a reliable toolkit for both everyday breathing and the moments when COPD flares make everything harder.
