Taking care of your lungs involves more than just medications and medical appointments. For people living with chronic respiratory conditions such as COPD, asthma, pulmonary fibrosis, or other lung diseases, nutrition, exercise, and breathing therapy can work together to support better breathing, strength, energy, and quality of life.
These strategies are also important components of pulmonary rehabilitation, a comprehensive approach that combines exercise, education, behavior change, and other individualized interventions to help people with chronic respiratory disease become more active and manage symptoms.
But how do these three areas work together?
Nutrition: Fueling the Body for Breathing
Breathing requires energy. Your respiratory muscles—including the diaphragm and muscles between the ribs—work continuously, even while you sleep.
Good nutrition provides the body with the energy, protein, vitamins, minerals, and other nutrients it needs to maintain muscle strength and support overall health.
For people with chronic lung disease, maintaining a healthy nutritional status can be particularly important. COPD, for example, can be associated with weight loss and loss of muscle mass, while excess weight can also contribute to limitations in physical activity and breathing. Nutritional assessment is therefore an important part of comprehensive respiratory care.
A balanced eating pattern can include:
- Fruits and vegetables
- Whole grains
- Lean sources of protein
- Healthy fats
- Adequate fluids, when appropriate
- Nutrient-dense foods that provide plenty of nutrition without excessive calories
A registered dietitian can help develop an individualized nutrition plan, particularly if you have experienced nutrition-related concerns such as, unintended weight loss, muscle loss, obesity, or swallowing difficulties.
Exercise: Building Strength and Endurance
When breathing is difficult, exercise may seem counterintuitive. Many people with chronic lung disease become less active because they are afraid of becoming short of breath.
Unfortunately, avoiding activity can lead to deconditioning. Weaker muscles require more effort to perform everyday activities, which can make physical activity feel even more difficult.
Pulmonary rehabilitation helps to stop this cycle by using individualized exercise training to gradually improve endurance and strength. Exercise is considered a cornerstone of pulmonary rehabilitation.
Depending on your health and abilities, an exercise program may include:
- Walking
- Stationary cycling
- Strength training
- Upper-body exercises
- Stretching and flexibility exercises
- Breathing exercises during physical activity
The goal isn’t necessarily to become an athlete, rather to make everyday activities, such as walking, climbing stairs, shopping, or doing household chores, more manageable.
Breathing Therapy: Learning to Use Your Breath More Effectively
Breathing techniques can help some people manage breathlessness and coordinate breathing with activity.
One commonly taught technique is pursed-lip breathing. It involves breathing in gently and then slowly breathing out through pursed lips. This technique can help slow the breathing pattern and may reduce the sensation of breathlessness during activity.
Another technique is diaphragmatic or belly breathing, which focuses on using the diaphragm rather than relying primarily on the muscles of the chest and shoulders. The American Lung Association recommends practicing breathing exercises regularly so that the techniques become more familiar before they are needed during episodes of breathlessness.
Breathing therapy may also teach people how to:
- Pace their breathing during activity
- Coordinate breathing with movement
- Recover from breathlessness
- Reduce unnecessary rapid breathing
- Use breathing strategies during exercise

Why These Three Areas Work Better Together
Nutrition, exercise, and breathing therapy aren’t separate strategies. They can reinforce one another.
Nutrition supports the muscles. Adequate nutrition helps provide the building blocks needed to maintain muscle mass and strength.
Exercise trains the muscles. Regular, appropriately prescribed activity helps improve endurance and strength so everyday movements require less effort.
Breathing therapy helps manage the work of breathing. Learning controlled breathing techniques can help people use their breathing more effectively during activity and episodes of breathlessness.
Together, these approaches can create a positive cycle:
Better nutrition → stronger muscles → improved activity tolerance → more confidence with exercise → better physical conditioning → improved ability to manage breathlessness.
This integrated approach is one reason pulmonary rehabilitation programs commonly include exercise, education, breathing strategies, and nutrition-related support.
What Does a Typical Approach Look Like?
A personalized program might begin with an evaluation of your symptoms, exercise capacity, nutritional status, medications, and daily activities.
From there, your healthcare team may recommend:
A personalized exercise program
You might start with short periods of walking or other low-impact activity and gradually increase the duration and intensity as your fitness improves.
Breathing exercises
A respiratory therapist or pulmonary rehabilitation professional may teach you breathing techniques and help you practice them while walking or performing other activities.
Nutrition support
If you are losing weight or muscle mass, a dietitian may recommend strategies to increase protein and overall nutrient intake. If excess weight is affecting mobility or breathing, your healthcare team may recommend a different nutritional approach.
Education and self-management
Pulmonary rehabilitation can also teach patients about medications, oxygen therapy, recognizing symptoms, managing exacerbations, and maintaining healthy behaviors. (American Thoracic Society)
Don’t Forget About Rest and Recovery
Exercise is important, but recovery matters too.
Getting adequate sleep, allowing your muscles to recover between workouts, staying hydrated when appropriate, and following your healthcare provider’s treatment plan can all support your progress.
If you use supplemental oxygen, follow your prescribed oxygen instructions during exercise. Do not change your oxygen flow rate on your own unless your healthcare provider has instructed you to do so.
When Should You Stop Exercising?
Exercise should be individualized for people with respiratory disease.
Stop exercising and contact your healthcare provider if you experience concerning symptoms such as new or worsening shortness of breath, chest pain, dizziness, unusual weakness, or other significant changes. The American Lung Association specifically recommends avoiding exercise when you have symptoms such as fever or infection, chest pain, increased shortness of breath, or dizziness.
Always talk with your healthcare provider before beginning or significantly changing an exercise program, particularly if you have an underlying heart or lung condition.
The Role of Pulmonary Rehabilitation
For people who struggle with chronic respiratory symptoms, pulmonary rehabilitation can provide a structured way to bring these strategies together.
Pulmonary rehabilitation programs are typically multidisciplinary and may include respiratory therapists, physicians, exercise specialists, dietitians, nurses, physical therapists, pharmacists, and other healthcare professionals.
Research and clinical guidelines support pulmonary rehabilitation as an important component of care for several chronic respiratory conditions. The American Thoracic Society’s 2023 clinical practice guideline strongly recommends pulmonary rehabilitation for adults with stable COPD and after hospitalization for COPD exacerbation, among other recommendations.
Small Changes Can Make a Difference
Improving respiratory health doesn’t always require making dramatic changes overnight.
Start with manageable goals:
- Add a short walk to your daily routine (if medically appropriate).
- Practice your breathing exercises regularly.
- Choose nutrient-dense foods.
- Include adequate protein to support muscle health.
- Follow your prescribed medications and treatment plan.
- Track symptoms and communicate changes to your healthcare team.
- Ask whether pulmonary rehabilitation may be appropriate for you.
Over time, these small steps can become part of a sustainable approach to managing respiratory health.
The Bottom Line
Nutrition, exercise, and breathing therapy work best as parts of the same overall strategy.
Nutrition helps provide the fuel and nutrients your body needs. Exercise helps build the strength and endurance required for daily activities. Breathing therapy can help you develop strategies for managing breathlessness and coordinating your breathing with movement.
For people with chronic respiratory disease, combining these approaches through a personalized treatment or pulmonary rehabilitation program can help improve exercise tolerance, symptoms, and quality of life.
Talk with your healthcare provider or respiratory care team about which strategies are appropriate for your condition. With the right plan, better breathing isn’t just about your lungs, it’s about strengthening the whole body that helps you breathe.
