Sarah, a vibrant graphic designer in her late 30s, often found herself sighing deeply, not out of sadness, but as if her lungs just weren’t quite getting enough air. Living in a bustling city, battling seasonal allergies, and spending long hours hunched over her computer, she felt a persistent tightness in her chest. It wasn’t pain, just a subtle, unsettling feeling that her lungs weren’t fully “open,” that she wasn’t truly breathing to her full potential. She craved that refreshing, invigorating feeling of a deep, uninhibited breath, like standing on a mountain peak or by the ocean. Like many folks, she wondered: How do I naturally open my lungs?

To answer directly, naturally opening your lungs primarily involves a combination of conscious breathing techniques, regular physical activity, maintaining optimal hydration, improving indoor air quality, adopting a nutrient-rich diet, and practicing good posture. These integrated approaches work synergistically to enhance lung capacity, improve respiratory muscle function, and promote overall respiratory health, helping you feel like you can truly take a full, satisfying breath.

The Unseen Struggle: Why Our Lungs Might Feel “Closed”

It’s a common sentiment, that feeling of not quite getting enough air, even when there’s no immediate danger. Modern life, unfortunately, presents numerous challenges to our respiratory systems. Think about it: we often spend our days in a slightly slumped position, whether at a desk or looking at a phone. This posture naturally compresses the chest cavity, restricting the diaphragm’s full movement. Add to that the pervasive stress of daily life, which often leads to shallow, rapid chest breathing, rather than the deep, calming belly breaths our bodies are designed for. Environmental factors, like urban air pollution, indoor allergens, and even the dry air from heating or air conditioning, can also irritate our airways, making them feel less expansive.

Understanding a little bit about how our lungs work can shed some light here. Your lungs aren’t just empty balloons; they’re intricate organs comprised of millions of tiny air sacs called alveoli, where oxygen is exchanged for carbon dioxide. For optimal function, these alveoli need to be consistently expanded and well-ventilated. When we breathe shallowly, or when our airways are irritated or inflamed, some of these smaller air sacs might not fully open, leading to that “closed” or restricted feeling. Our respiratory muscles, especially the diaphragm, also need to be strong and flexible. Just like any other muscle, if they’re not used optimally, they can weaken or become less efficient.

Breathing Techniques: The Foundation of Lung Expansion

Conscious breathing exercises are arguably the most direct and potent way to naturally open your lungs. These aren’t just about taking a deep breath; they’re about retraining your body to use its full respiratory capacity more effectively. It’s truly a game-changer.

Diaphragmatic Breathing (Belly Breathing)

This is the bedrock of healthy respiration, yet many of us, especially as adults, have forgotten how to do it naturally. Babies breathe this way instinctively. Diaphragmatic breathing focuses on engaging your diaphragm, a dome-shaped muscle located at the base of your lungs, which is your primary muscle for breathing. When it contracts, it moves downwards, creating more space in your chest cavity and drawing air deeply into your lungs. Relying on your diaphragm rather than your upper chest muscles reduces the effort of breathing, conserves energy, and promotes a fuller oxygen exchange.

How to Practice Diaphragmatic Breathing:

  1. Find a Comfortable Position: Lie on your back with your knees bent and a pillow under your head, or sit upright in a chair with good posture. Place one hand on your chest and the other on your belly, just below your rib cage.
  2. Inhale Deeply: Breathe in slowly and deeply through your nose, allowing your belly to rise as your diaphragm pushes down. You should feel the hand on your belly lift, while the hand on your chest remains relatively still.
  3. Exhale Slowly: Purse your lips slightly (as if blowing through a straw) and exhale slowly, feeling your belly gently fall inwards. Try to make your exhalation longer than your inhalation.
  4. Repeat: Continue for 5-10 minutes, several times a day. Focus on keeping your shoulders and neck relaxed.

In my experience, consistent practice of diaphragmatic breathing can dramatically reduce feelings of breathlessness and significantly increase your awareness of your breathing patterns throughout the day.

Pursed-Lip Breathing

Pursed-lip breathing is another fantastic technique, especially if you ever feel a little short of breath. It helps to slow down your breathing rate, makes each breath more effective, and keeps your airways open longer during exhalation. This can be particularly helpful for folks with conditions like asthma or COPD, but it’s beneficial for anyone looking to improve their breath control and expel more stale air from their lungs.

How to Practice Pursed-Lip Breathing:

  1. Relax: Sit comfortably and relax your neck and shoulders.
  2. Inhale: Breathe in slowly through your nose for a count of two, keeping your mouth closed.
  3. Pucker: Pucker your lips as if you’re about to whistle or gently blow out a candle.
  4. Exhale: Exhale slowly and gently through your pursed lips for a count of four or more, making your exhalation at least twice as long as your inhalation.
  5. Repeat: Practice this throughout the day, especially when you feel short of breath or stressed.

Box Breathing (Four-Square Breathing)

Box breathing is a simple yet powerful technique often used to calm the nervous system and improve focus, which in turn leads to more relaxed and deeper breathing. It’s a great tool for stress reduction, and stress, as we know, can really tighten up our breathing.

How to Practice Box Breathing:

  1. Exhale Completely: Gently exhale all the air from your lungs.
  2. Inhale (Count of 4): Inhale slowly through your nose for a count of four.
  3. Hold (Count of 4): Hold your breath for a count of four.
  4. Exhale (Count of 4): Exhale slowly through your mouth for a count of four.
  5. Hold (Count of 4): Hold your breath again for a count of four before the next inhale.
  6. Repeat: Continue this cycle for several minutes, visualizing the four sides of a box as you move through each step.

Deep Yawn/Sigh Exercises

Have you ever noticed how satisfying a deep yawn or sigh can be? There’s a reason for that. Our bodies instinctively use these actions to reset our breathing and expand our alveoli. You can intentionally replicate this sensation. A deep sigh, often accompanied by an audible “ahhhh” sound, helps to release tension and allows for a more complete exhalation, making way for a fresh, full inhale.

How to Do a Deep Yawn/Sigh:

  • Take a slow, deep breath in, letting your chest and belly expand fully, almost like a suppressed yawn.
  • Hold it for a moment, feeling the stretch.
  • Then, release the breath with a long, gentle sigh through your mouth, allowing your body to soften.
  • Repeat a few times whenever you feel like you need a “reset.”

Physical Activity: Your Lungs’ Best Workout

Just like any other muscle in your body, your respiratory muscles benefit from regular exercise. Engaging in physical activity is one of the most effective natural ways to strengthen your lungs, increase their capacity, and improve their efficiency. It’s pretty much a non-negotiable for lung health.

Cardiovascular Exercise

Aerobic activities are particularly excellent for your lungs. When you engage in brisk walking, jogging, cycling, swimming, or dancing, your heart rate increases, and your body demands more oxygen. This forces your lungs to work harder, leading to several beneficial adaptations:

  • Increased Lung Capacity: Over time, your lungs become more efficient at taking in oxygen and expelling carbon dioxide, meaning you can process more air with each breath.
  • Stronger Respiratory Muscles: The muscles responsible for breathing, including your diaphragm and intercostal muscles (between your ribs), become stronger and more coordinated.
  • Improved Oxygen Utilization: Your body gets better at extracting oxygen from the air you breathe and delivering it to your muscles.

Aim for at least 30 minutes of moderate-intensity aerobic activity most days of the week. Even breaking it up into shorter 10-minute bursts can make a difference.

Yoga and Pilates

These practices are fantastic because they combine physical postures with a strong emphasis on breath-work and body awareness. They don’t just build strength and flexibility; they actively encourage deeper, more controlled breathing, which is precisely what we’re after when we talk about opening the lungs.

  • Yoga: Many yoga poses, especially chest openers like Cobra, Camel, or Fish Pose, gently stretch the intercostal muscles and expand the rib cage, creating more space for the lungs. The intentional linking of breath to movement (Vinyasa) further enhances respiratory control and capacity.
  • Pilates: Pilates focuses on core strength, but it places a significant emphasis on controlled, diaphragmatic breathing. By strengthening the core, it supports the diaphragm and allows for more efficient respiration.

Incorporating these practices can provide a holistic benefit, addressing posture, muscle strength, and breath control all at once.

Hydration and Nutrition: Fueling Respiratory Health

What you put into your body has a profound impact on every system, and your respiratory system is no exception. Proper hydration and a diet rich in certain nutrients can make a real difference in how “open” and comfortable your lungs feel.

Water: The Unsung Hero

It might seem basic, but staying well-hydrated is absolutely crucial for lung health. The lining of your airways produces mucus, which acts as a protective barrier, trapping dust, allergens, and pathogens. When you’re dehydrated, this mucus can become thick and sticky, making it harder for your cilia (tiny hair-like structures in your airways) to clear it out. This can lead to congestion, irritation, and that feeling of “closed” airways.

Drinking plenty of water throughout the day helps keep your mucus thin and flowing, allowing your lungs to naturally clear themselves more effectively. Aim for at least eight 8-ounce glasses of water daily, and more if you’re active or in a dry environment.

Anti-inflammatory Foods: Calming the Airways

Inflammation in the airways can constrict them, making breathing more difficult. A diet rich in anti-inflammatory foods can help soothe your respiratory system.

  • Berries: Blueberries, raspberries, and strawberries are packed with antioxidants and flavonoids that help reduce inflammation.
  • Leafy Greens: Spinach, kale, and collard greens are excellent sources of vitamins, minerals, and antioxidants.
  • Fatty Fish: Salmon, mackerel, and sardines are rich in Omega-3 fatty acids, known for their powerful anti-inflammatory properties.
  • Turmeric: This golden spice contains curcumin, a compound with well-documented anti-inflammatory effects.
  • Ginger: Often used to calm upset stomachs, ginger also has potent anti-inflammatory and antioxidant properties that can benefit the respiratory system.

Antioxidant-Rich Foods: Protecting Against Damage

Our lungs are constantly exposed to environmental toxins and free radicals. Antioxidants help protect lung tissue from damage caused by these elements.

  • Vitamin C: Found in citrus fruits, bell peppers, broccoli, and kiwi. It’s a powerful antioxidant that supports immune function and lung health.
  • Vitamin E: Abundant in nuts, seeds, and leafy greens. It protects cells from oxidative stress.
  • Beta-Carotene: Found in carrots, sweet potatoes, and pumpkin. It’s a precursor to Vitamin A, vital for maintaining healthy mucous membranes in the respiratory tract.

Foods to Limit

While focusing on what to eat, it’s also wise to consider what to limit. Highly processed foods, excessive sugar, and sometimes even dairy can contribute to inflammation or increased mucus production in some individuals. Paying attention to how certain foods make you feel can provide valuable insights into your own body’s unique needs.

Environmental Factors: Cleaning Up Your Air

You can breathe all the deeply you want, but if the air itself is full of irritants, your lungs are going to feel a bit of a struggle. Cleaning up your environment is a crucial step in naturally opening your lungs.

Indoor Air Quality

Given how much time most Americans spend indoors, the quality of our indoor air is paramount. Often, indoor air can be more polluted than outdoor air.

  • Ventilation: Regularly open windows and doors, even for a few minutes, to allow fresh air to circulate. This helps to dilute indoor pollutants.
  • Air Purifiers: Consider investing in a high-efficiency particulate air (HEPA) filter air purifier. These devices can capture tiny particles like dust, pollen, pet dander, and mold spores that can irritate your airways.
  • Natural Plants: Some houseplants, like spider plants, peace lilies, and snake plants, are known for their air-purifying qualities, though their impact on overall air quality in a large room might be modest, they certainly don’t hurt!
  • Avoid Irritants: This is a big one. Steer clear of indoor smoking (obviously), strong chemical cleaners, air fresheners with synthetic fragrances, and excessive burning of candles or incense, which can release particulate matter. Opt for natural, unscented cleaning products.

Outdoor Air Quality

While you can’t control outdoor air quality, you can be smart about when and where you expose yourself to it.

  • Check Air Quality Reports: Many weather apps and websites provide daily air quality index (AQI) reports. On days with high pollution levels, especially if you have sensitive lungs, it might be better to exercise indoors or limit prolonged outdoor activity.
  • Avoid Peak Pollution Times: Traffic-heavy hours often correspond with higher levels of outdoor air pollution. If you’re exercising outdoors, try to do so in the early morning or late evening when traffic is lighter.
  • Seek Green Spaces: When possible, exercise in parks or natural areas away from major roads, as trees and plants can help filter the air.

Humidity: Maintaining Optimal Levels

Both overly dry and excessively humid air can impact lung comfort. Dry air can irritate airways and dry out mucous membranes, while overly humid air can promote mold growth and make breathing feel heavy.

  • Humidifiers: In dry climates or during winter months when indoor heating dries out the air, a humidifier can help maintain optimal humidity levels (ideally between 30-50%). Clean it regularly to prevent mold.
  • Dehumidifiers: In very humid environments, a dehumidifier can help reduce moisture, preventing mold and dust mite proliferation, both common allergens.

Posture: Unlocking Your Rib Cage

This is often overlooked, but it’s a real foundational piece to naturally opening your lungs. Think about it: when you slouch, your rib cage collapses inwards, and your shoulders round forward. This physically compresses your lungs and restricts the natural movement of your diaphragm. It’s like trying to sing with your mouth half-closed – you just can’t produce your full potential.

Good posture, on the other hand, allows your rib cage to expand fully, giving your lungs ample space to inflate. It also ensures that your diaphragm can move freely, leading to more efficient and deeper breaths. It’s a simple adjustment that yields big benefits.

Tips for Better Posture:

  • Sitting: Ensure your feet are flat on the floor, your back is supported (perhaps with a small cushion in the lumbar curve), and your shoulders are relaxed and back, not hunched forward. Your computer screen should be at eye level to prevent neck strain.
  • Standing: Imagine a string pulling gently from the crown of your head, lengthening your spine. Keep your shoulders back and down, chest open, and engage your core slightly.
  • Mindfulness: Regularly check in with your posture throughout the day. Set a timer to remind yourself to adjust.

Stretching Exercises for the Chest and Back:

Incorporating gentle stretches can help undo the tightness caused by poor posture and open up your chest cavity. Here are a couple to try:

  1. Doorway Chest Stretch: Stand in a doorway, place your forearms on the door frame on either side, and gently step forward until you feel a stretch across your chest. Hold for 20-30 seconds.
  2. Cat-Cow Stretch: On your hands and knees, arch your back like a cat on an exhale, then drop your belly and lift your head on an inhale like a cow. This movement mobilizes the spine and rib cage, promoting better breathing mechanics.

Herbal Support and Natural Remedies for Respiratory Comfort

While herbs aren’t a quick fix for “opening” your lungs in the physiological sense of the word, certain natural remedies and herbal allies have been traditionally used to support respiratory comfort, soothe irritated airways, and thin mucus, making breathing feel easier and more open. Always approach these with an understanding that they complement, rather than replace, conventional medical care, and it’s wise to consult with a healthcare professional before starting any new herbal regimen, especially if you have existing health conditions or are taking medications.

Herbal Allies:

  • Eucalyptus: This powerful essential oil is renowned for its ability to help clear congested airways. Its main component, eucalyptol, acts as an expectorant, helping to thin mucus. You can use eucalyptus oil in a diffuser, add a few drops to a steam inhalation, or use chest rubs containing it.
  • Peppermint: Like eucalyptus, peppermint contains menthol, which provides a cooling sensation and can help open up nasal passages, making it feel easier to breathe. Peppermint tea or essential oil (used similarly to eucalyptus) can be beneficial.
  • Mullein: Mullein leaf has been traditionally used to support respiratory health, often as a tea. It’s thought to have soothing and expectorant properties, helping to calm irritation and loosen phlegm.
  • Thyme: This common kitchen herb is also used in herbal medicine for its antimicrobial and antispasmodic properties, which can be helpful for coughs and respiratory discomfort. Thyme tea is a popular preparation.
  • Ginger and Honey: A simple concoction of fresh ginger slices steeped in hot water with a spoonful of honey is a classic remedy for soothing sore throats and easing coughs, indirectly contributing to respiratory comfort.

Steam Inhalation: A Simple, Effective Method

One of the most immediate and pleasant ways to find respiratory relief is through steam inhalation. Inhaling warm, moist air helps to:

  • Moisturize Airways: It rehydrates the delicate tissues lining your respiratory tract.
  • Thin Mucus: The warmth and moisture help to thin thick mucus, making it easier to cough up and clear from your lungs and nasal passages.
  • Soothe Irritation: It can provide a comforting sensation to irritated airways.

How to Perform Steam Inhalation:

  1. Boil Water: Heat water to a comfortable, but not scalding, temperature.
  2. Prepare Bowl: Pour the hot water into a large, heat-proof bowl.
  3. Add Extras (Optional): You can add a few drops of eucalyptus or peppermint essential oil (be cautious, as some people are sensitive), or a handful of fresh herbs like thyme or rosemary.
  4. Inhale: Drape a towel over your head and the bowl, creating a tent. Close your eyes and lean over the bowl, inhaling the steam through your nose and mouth for 5-10 minutes.
  5. Take Breaks: If the steam feels too intense, lift the towel and take a break.

Again, I can’t stress this enough: While these natural remedies can be wonderfully supportive, they are not substitutes for professional medical advice, especially if you’re experiencing persistent respiratory issues.

Mind-Body Connection: Stress and Respiration

The connection between your mind and your body is incredibly powerful, and nowhere is this more evident than in your breathing. When you’re stressed, anxious, or overwhelmed, your body often shifts into “fight or flight” mode. This physiological response typically involves shallow, rapid breathing originating from the chest, rather than deep, slow breaths from the diaphragm. This type of breathing can perpetuate feelings of anxiety and, over time, limit your lung’s natural ability to expand fully.

Learning to manage stress is not just good for your mental well-being; it’s a direct pathway to more relaxed, open breathing.

Meditation and Mindfulness: Cultivating Calmer Breaths

  • Mindful Breathing: Simply bringing your awareness to your breath, observing its natural rhythm without trying to change it, can be incredibly powerful. Notice the sensation of air entering and leaving your body. This practice helps to slow down your breathing and shift it towards a more diaphragmatic pattern.
  • Meditation: Regular meditation practice teaches you to observe your thoughts and feelings without judgment, reducing overall stress and anxiety. Many meditation techniques involve focusing on the breath as an anchor, which naturally encourages deeper, fuller inhalations and exhalations. Even just 5-10 minutes a day can make a difference.
  • Body Scans: A body scan meditation involves systematically bringing your awareness to different parts of your body, noticing any tension and consciously relaxing it. This can include your chest, shoulders, and diaphragm, helping to release physical tension that might be restricting your breath.

When you foster a calmer state of mind, your nervous system can relax, allowing your respiratory muscles to ease up and your lungs to expand more freely. It’s a holistic approach that truly supports your entire being.

Putting It All Together: A Daily Checklist for Lung Vitality

To truly naturally open your lungs and maintain that expansive feeling, consistency is key. Here’s a daily checklist you can use to integrate these practices into your routine:

  • Morning Breathwork (5-10 minutes): Start your day with diaphragmatic breathing or box breathing to set a calm tone and engage your diaphragm.
  • Hydrate Continuously: Keep a water bottle handy and sip throughout the day to ensure optimal mucus consistency.
  • Move Your Body (30+ minutes): Incorporate moderate cardiovascular exercise or a yoga/Pilates session.
  • Check Your Posture: Periodically adjust your sitting and standing posture, especially if you spend a lot of time at a desk. Gentle chest stretches can help too.
  • Mindful Eating: Prioritize anti-inflammatory and antioxidant-rich foods in your meals and snacks.
  • Fresh Air Breaks: Open windows for a few minutes to air out your living space. Consider a short walk in nature if air quality permits.
  • Stress Reduction: Engage in a few minutes of mindful breathing or meditation, especially if you feel tension building up.
  • Evening Steam (Optional): If you feel congested or want to unwind, a gentle steam inhalation can be a comforting addition.

Remember, this isn’t about perfection, but about consistent, small steps that build up over time. You’ll likely start to notice a significant difference in how you feel and how easily you breathe.

When to Seek Professional Help

While these natural methods are incredibly powerful for enhancing lung health and promoting a feeling of openness, it’s absolutely crucial to know when to consult a healthcare professional. Natural approaches are complementary and supportive, but they are not a substitute for medical diagnosis or treatment.

If you’re experiencing persistent or worsening respiratory symptoms, it’s vital to seek medical advice. These symptoms might include chronic shortness of breath, wheezing, persistent coughing, chest pain, recurring respiratory infections, or any sudden changes in your breathing patterns. These could be signs of underlying medical conditions such as asthma, chronic obstructive pulmonary disease (COPD), allergies, or other lung conditions that require specific medical attention and management. Your doctor can provide an accurate diagnosis, rule out serious conditions, and recommend appropriate treatments, including lung function tests or referrals to specialists like pulmonologists. Addressing any underlying issues medically will give you the best foundation for supporting your lungs with natural methods.

Frequently Asked Questions (FAQ)

Can lungs heal naturally?

Yes, to a remarkable extent, lungs possess a natural capacity for healing and regeneration, especially when provided with the right conditions. For instance, if you quit smoking, your lungs immediately begin a repair process, clearing out mucus and toxins, and reducing inflammation. New, healthy cells can even start to grow. Similarly, if your lungs have been irritated by temporary environmental factors, removing the irritant and supporting your body with healthy practices can lead to significant natural recovery.

However, it’s important to understand the limits. While minor damage or inflammation can often be reversed or improved, severe or long-standing damage from conditions like emphysema (a form of COPD) or extensive scarring from certain diseases might not fully heal. Even in such cases, though, adopting natural, supportive practices can significantly improve lung function, reduce symptoms, and prevent further deterioration, enhancing your overall quality of life and breathing comfort. It’s about optimizing what your lungs can do.

What are the best drinks for lung cleansing?

When people talk about “lung cleansing” drinks, they’re generally referring to beverages that support overall respiratory health by promoting hydration, reducing inflammation, or providing antioxidants. There isn’t a magical drink that will “scrub” your lungs clean, but several options can be beneficial.

Water is hands down the most important. Staying well-hydrated keeps mucus thin and flowing, allowing your lungs to naturally clear themselves of irritants and pathogens. Herbal teas like ginger tea, peppermint tea, or mullein tea can be soothing due to their anti-inflammatory properties and ability to help clear congestion. Green tea is another excellent choice, rich in antioxidants that protect lung tissue. Drinks rich in Vitamin C, like orange juice or lemon water, also support immune function and may help reduce inflammation. The key is consistent hydration and nutrient intake to support your body’s natural cleansing mechanisms.

How long does it take to increase lung capacity naturally?

The timeline for increasing lung capacity naturally can vary significantly from person to person, depending on your starting fitness level, consistency of practice, and overall health. Generally, you can start to notice improvements in your breathing and stamina within a few weeks of consistently implementing breathing exercises and regular physical activity.

Significant increases in lung capacity and efficiency, however, often take several months. Think about it like building muscle: you don’t get strong overnight. With dedicated practice of diaphragmatic breathing, regular cardiovascular exercise, and maintaining healthy lifestyle habits, your respiratory muscles will strengthen, your alveoli will become more efficient, and your body will adapt to utilize oxygen better. It’s a gradual, ongoing process, but the benefits, like feeling less winded and taking fuller, more satisfying breaths, are well worth the commitment.

Is deep breathing always good for your lungs?

For the vast majority of people, deep breathing exercises, when performed correctly and mindfully, are incredibly beneficial for lung health. They help strengthen respiratory muscles, increase lung capacity, improve oxygen exchange, and promote relaxation by activating the parasympathetic nervous system. It’s a cornerstone of good respiratory hygiene.

However, there can be rare instances or specific contexts where certain types of deep breathing might need to be approached with caution or guidance. For example, if someone has a severe underlying lung condition (like a collapsed lung or acute asthma attack) or certain heart conditions, or is recovering from surgery, they should always consult their doctor before starting any new breathing regimen. Overly forced or hyperventilating breaths can also cause dizziness or lightheadedness, so it’s essential to breathe gently and listen to your body. For most healthy individuals looking to enhance their natural breathing, deep, controlled breathing is overwhelmingly positive and safe.

What are signs of healthy lungs?

Healthy lungs contribute to an overall feeling of vitality and well-being. There are several key signs that indicate your lungs are functioning well. Firstly, you should be able to breathe effortlessly and comfortably, without any conscious effort or sensation of shortness of breath, even during moderate physical activity. Your breathing should feel quiet and smooth, both at rest and during exertion, without any wheezing, crackling, or persistent coughing.

Another strong indicator of healthy lungs is good stamina and energy levels. If your lungs are efficiently delivering oxygen to your bloodstream, your muscles and organs receive the fuel they need, preventing easy fatigue. A robust immune system, meaning you don’t frequently get respiratory infections like colds or bronchitis, also points to healthy lung defenses. Furthermore, a clear and resonant voice, without hoarseness, often suggests clear airways. Finally, the absence of chronic chest pain, tightness, or persistent phlegm production are all positive signs that your lungs are in good shape and able to do their vital work without undue strain or irritation.
