Breathing Exercises and Pulmonary Rehabilitation
A practical, step-by-step guide to diaphragmatic and pursed-lip breathing, how pulmonary rehabilitation works, who benefits, and the warning signs that mean you should seek medical help.

Breathing exercises are simple, low-cost techniques that teach you to deliberately slow your breathing rate and use your diaphragm more efficiently; practiced regularly, they help reduce the sensation of breathlessness, make each breath more effective, and let you use less energy to breathe during everyday activities [1]. On their own they are not a cure. Their strongest effect appears when they are part of a wider programme known as pulmonary rehabilitation. Pulmonary rehabilitation is a comprehensive, individually tailored intervention built around a thorough patient assessment and combining exercise training, controlled breathing techniques, education, and behaviour change; in people with chronic respiratory disease it has been clearly shown to reduce breathlessness, increase exercise capacity, and improve quality of life [4].
This article explains who breathing exercises are meant for, what benefits they offer, and how to practice them safely at home, step by step. It also sets out clearly which symptoms should prompt you to stop exercising and seek medical or emergency care. The goal is to give you a trustworthy starting point for understanding your own breathing — and for knowing when to ask a professional for support.
Who are breathing exercises for?
Breathing exercises are most often recommended to people who live with a chronic lung condition and experience shortness of breath. Pursed-lip breathing and diaphragmatic (belly) breathing are the two techniques most commonly taught by pulmonary rehabilitation specialists for conditions such as chronic obstructive pulmonary disease (COPD) and asthma [1]. In these conditions it becomes harder to empty air from the lungs, so a person tends to breathe quickly and shallowly; the techniques aim to slow that cycle and help you regain control of your breath.
Beyond this, people who are immobile after surgery, those who are bed-bound, people whose breathing muscles have weakened with age, and those left short of breath after a prolonged illness may also benefit — when appropriate and after assessment by a professional. The diaphragm is the primary breathing muscle and performs roughly 80% of the work of breathing; training it to work more efficiently reduces the unnecessary load placed on the neck and shoulder muscles, which are not designed for breathing work [3].
One point matters greatly: breathing exercises are not equally suitable for everyone. If you have new, unexplained shortness of breath that has not been diagnosed, you should be assessed by a clinician before starting any exercise. These techniques help you manage an existing breathing problem; they do not replace urgent care for a serious or sudden symptom. If you live with COPD or a similar diagnosis, the safest approach is to plan how to use these techniques as part of your treatment together with the team that follows your COPD and respiratory health.
What are the benefits of breathing exercises?
The most tangible benefit of breathing exercises is that they make breathlessness (dyspnoea) easier to manage. Pursed-lip breathing offers a quick, easy way to slow your pace of breathing and makes each breath more effective; when you feel short of breath it helps get more oxygen into your lungs and calms you so you can better control your breath [1]. Physiologically, the technique creates a small back-pressure in the airways during exhalation (a little positive end-expiratory pressure), which keeps the airways open longer; it slows the respiratory rate, increases tidal volume, and helps restore diaphragmatic function [2].
Diaphragmatic breathing, in turn, retrains the primary breathing muscle to work more efficiently and reduces the strain on the neck and shoulder muscles that are not built for breathing work [1]. Studies show that performing pursed-lip and diaphragmatic breathing — either alone or in combination — is an effective way to relieve dyspnoea-related distress [2].
The benefits become clearer when these techniques sit inside a wider pulmonary rehabilitation programme. According to the ATS/ERS guideline, pulmonary rehabilitation reduces dyspnoea, increases exercise capacity, improves health-related quality of life and emotional function, and — in people with COPD — reduces the risk of hospital readmission and death after hospitalisation [4]. A large Cochrane review likewise found that pulmonary rehabilitation produces clinically meaningful improvements in quality of life, dyspnoea, fatigue, emotional function, and exercise capacity in COPD [5]. In short, when breathing exercises are combined with a programme that builds movement and exercise capacity, they can mean not just "breathing more comfortably" but a more active, less anxious daily life.
Step-by-step breathing exercises
The techniques below are for general information and should be tried in a calm, unpressured setting. Stop if you feel dizzy, develop chest pain, or notice increased breathlessness during the exercise. If you have a new breathing problem or live with a diagnosis, practice these only with your own care team's approval.
1. Pursed-lip breathing
This technique is especially useful during a moment of breathlessness or right after activity.
- ·Sit comfortably in a chair and relax your neck and shoulder muscles [1].
- ·With your mouth closed, breathe in slowly through your nose for about two seconds [2].
- ·Purse your lips as if you were going to whistle or gently flicker a candle — not blow it out [1].
- ·Breathe out slowly and gently through those pursed lips, taking longer to exhale than you did to inhale (about four to six seconds) [1].
- ·Repeat for several rounds and notice your breathing rate settle naturally.
2. Diaphragmatic (belly) breathing
This technique aims to retrain your primary breathing muscle and is best practiced while calm.
- ·Lie on your back on a flat surface with your knees bent; you can also sit upright in a comfortable chair if you prefer [3].
- ·Place one hand on your upper chest and the other just below your rib cage, on your belly [3].
- ·Breathe in slowly through your nose, directing the air deep towards your lower belly; the hand on your chest should stay still while the hand on your belly rises [3].
- ·As you exhale, tighten your abdominal muscles and let them fall inward, breathing out through pursed lips [3].
- ·Imagining your belly filling with air like a balloon can make the technique easier to feel [1].
3. Breathing control
Breathing control means breathing gently, using the least effort. It is a more efficient way of breathing and helps you relax and feel in control. When you take a breath in, the diaphragm flattens and gently presses on the abdominal contents, causing your abdomen to expand. Keep your shoulders and upper chest loose and focus on breathing at your normal rate and natural depth. This technique is useful for settling down again after a bout of breathlessness.
4. Recovery positions
Certain body positions make it easier to recover from breathlessness and to practice breathing control. Leaning forward with your elbows resting on your knees can help, as can leaning your back or side against a wall with your feet slightly apart and your hands resting loosely by your sides. Resting your head and arms on pillows on a table when you are short of breath is another helpful position. Combining these positions with pursed-lip or breathing control can speed up recovery.
5. The "breathe first, then move" principle
A practical way to manage breathlessness during daily activities is to time the effort to your breath. When climbing stairs or lifting something, breathe in first, then breathe out as you make the demanding movement ("blow as you go"). Similarly, during rhythmic activities such as walking, pacing your breaths to your steps (paced breathing) makes the effort more manageable. Alongside assessments such as the Six-Minute Walk Test, which is used to gauge exercise capacity and track progress, these approaches help you use your breath more deliberately in everyday life.
How often should you practice?
As a general starting point, trying pursed-lip and diaphragmatic breathing a few times a day for a few minutes each is reasonable for most people; the aim is to make the techniques familiar enough to become almost reflexive in a moment of breathlessness. How long and how often you should practice is best decided together with the physiotherapist or clinician who follows you, in line with your diagnosis and goals.
When should you seek professional help?
Breathing exercises help you manage an existing breathing problem, but some symptoms require urgent assessment — and in those situations it is vital not to lose time on exercises.
Call emergency services (999/112) immediately, or go to the nearest emergency department, if you have any of the following:
- ·Severe difficulty breathing such as struggling to speak without pausing, gasping, or choking [6].
- ·Severe chest pain in the middle of your chest that does not go away, feeling like pressure, tightness, or squeezing — especially if it spreads to your arms, back, neck, or jaw [6].
- ·Chest pain with sweating, nausea, light-headedness, or shortness of breath — this could be a heart attack and needs immediate hospital treatment [6].
- ·Lips or skin turning very pale, blue, or grey, sudden confusion, fainting, or collapse [6].
- ·Coughing up blood, swelling in the throat, or sudden severe wheezing [6].
When breathlessness comes on suddenly and unexpectedly, it is usually a sign of a medical condition and should not be dismissed [6]. Apart from these red flags, if your breathlessness is getting worse over time, waking you at night, accompanied by swelling (oedema) in the legs, or not improving despite exercises, speak to your clinician in a planned way. Remember that the right first step is to have the cause assessed rather than starting a breathing-exercise programme without a diagnosis. If you are unsure whether a situation is an emergency, you can contact a health advice line for guidance [6].

Frequently Asked Questions
Do breathing exercises cure COPD?
No. Breathing exercises do not remove COPD; they are supportive techniques that help you manage breathlessness, slow your breathing rate, and make each breath more effective [1]. Used as part of a pulmonary rehabilitation programme, they can produce meaningful improvements in quality of life and exercise capacity [5]. Always manage your treatment plan together with the team that follows you.
Is pursed-lip or diaphragmatic breathing better?
Each has different strengths, and they are usually taught together. Pursed-lip breathing offers quick, practical relief during sudden breathlessness [1]. Diaphragmatic breathing focuses on retraining the primary breathing muscle and is best practiced while calm [3]. Studies show both are effective, alone or in combination [2].
How many times a day should I do breathing exercises?
For most people, a few times a day for a few minutes each is a reasonable starting point; the aim is to make the techniques familiar enough to become reflexive during breathlessness. The duration and frequency that suit you are best decided with your physiotherapist or clinician, based on your situation.
What should I do if I feel dizzy during an exercise?
Dizziness usually means you are breathing too fast or too deeply. Stop the exercise, return to your normal breathing rhythm, and rest for a few minutes. If dizziness keeps recurring, is severe, or comes with symptoms such as chest pain or a feeling of fainting, do not continue and consult a professional [6].
Are breathing exercises suitable for a bed-bound patient?
They may be, but only after assessment by a professional. Breathing muscles can weaken in people who are immobile; controlled and diaphragmatic breathing, combined with suitable positions, can be supportive. The physiotherapist following the patient should decide which techniques and positions are safe.
Is it normal for my breathlessness to increase while doing a breathing exercise?
No, that is not expected. The exercise is meant to ease your breathing; if breathlessness increases, stop. If the increase is severe, makes speaking difficult, or comes with symptoms such as chest pain or blue lips, seek emergency help [6].
When will I notice the effect of breathing exercises?
The calming effect of pursed-lip breathing is usually felt immediately, as it settles breathlessness [1]. More lasting improvements in exercise capacity and overall breathing function emerge over time with regular practice as part of a pulmonary rehabilitation programme [4][5]. Regular reassessment with your team helps you track progress.
Can a healthy person do breathing exercises?
Yes. Techniques such as breathing control and diaphragmatic breathing are simple habits that need no diagnosis and help with relaxation and using your breath more consciously. However, if you have new, unexplained shortness of breath, treat it not as an exercise topic but as a symptom that needs to be assessed [6].
