    Nasal Breathing

    After rediscovering the importance of a more conscious, diaphragmatic breath, the next step is to rediscover nasal breathing.

    nasal breathing

    Nasal breathing is not a trend nor an advanced technique: it is the physiological way our body is designed to breathe. And in recent years, science has begun to confirm what ancient traditions and body-based practices have long intuited.

    Why Breathing Through the Nose Makes a Difference

    The nose is not just an “air passage.” It is an active organ with specific functions:

    • It filters the air from dust and pathogens
    • It warms and humidifies the air before it reaches the lungs
    • It produces nitric oxide (NO), a key molecule for cardiovascular and respiratory health

    Studies published in the American Journal of Physiology and Frontiers in Physiology show that nasal breathing, compared to mouth breathing, is associated with:

    • greater activation of the parasympathetic nervous system
    • reduced resting diastolic blood pressure
    • better regulation of breathing and heart rate

    Nitric oxide produced in the paranasal sinuses, when we breathe through the nose, improves oxygen distribution in the lungs and promotes vasodilation. Mouth breathing, on the other hand, completely bypasses this mechanism.

    Nasal Breathing and the Nervous System

    One of the most interesting aspects concerns the relationship between nasal breathing and the brain.

    Research published in the Journal of Neuroscience indicates that nasal breathing:

    • modulates brain wave activity
    • influences memory, attention, and emotional regulation
    • promotes states of calm alertness compared to mouth breathing

    One study observed that nasal breathing is associated with better memory consolidation, while mouth breathing reduces this effect. This suggests that how we breathe can influence not only the body, but also cognitive functions.

    Open Mouth, Short Breath: Signals to Listen To

    Breathing predominantly through the mouth—especially at rest—can be associated with:

    • dry mouth and throat irritation
    • fatigue and difficulty concentrating
    • increased tension in the neck and chest
    • poorer sleep quality and snoring

    This is not a matter of “fault,” but of habit. Stress, poor posture, and fast-paced lifestyles easily push us toward rapid, mouth-based breathing, which over time becomes automatic.

    The good news is that the body can relearn.

    A First Practical Step: Conscious Nasal Breathing Exercise

    Before introducing more complex breathing rhythms (such as 4-4-8 or 4-7-8), it is useful to stabilize a simple and sustainable foundation.

    Exercise: Nasal Breathing with Prolonged Exhalation

    • Sit or lie down in a comfortable position
    • Inhale through the nose for 4 seconds, without forcing
    • Exhale slowly through the nose for 6 seconds
    • Keep the rhythm smooth, without holding the breath
    • Duration: 5–10 minutes

    A slightly longer exhalation promotes parasympathetic activation and helps the body “trust” nasal breathing.

    Studies on Heart Rate Variability show that this type of breathing improves cardiac coherence and reduces physiological markers of stress.

    Breathing Through the Nose Is a Daily Choice

    Nasal breathing does not require long sessions or special tools. It is a choice you can bring into:

    • walking
    • moments of pause
    • working or studying
    • before going to sleep

    It does not mean “never breathing through the mouth” (during intense effort it can happen), but rather returning to the nose as the main reference at rest and during light activities.

    Conclusion

    Breathing through the nose is one of the simplest and most powerful ways to make breathing more functional. There is no need to change everything at once: it is enough to begin observing, slowing down, and consciously choosing the right pathway.

    Next month, we will explore how breathing can become a direct tool to regulate stress and the nervous system, integrating rhythm, awareness, and physiology.

  • Functional breathing

    Functional breathing

    Let’s start from the foundations: understanding what functional breathing is, why it has such a strong impact on our well-being, and how to begin right away with a simple exercise suitable for everyone.

    We breathe thousands of times a day, often without noticing. Yet many people spend their entire lives with a short, shallow, fragmented breath—one that strains the body rather than supporting it.

    Why the breath deserves our attention

    In recent years, scientists, physiotherapists, and researchers have begun to look at breathing with growing interest. The reason is simple: the quality of our breath directly influences the quality of our life.

    Studies published in journals such as Frontiers in Psychology and the Journal of Applied Physiology show that slower, deeper, diaphragmatic breathing:

    • improves vagus nerve activation, promoting calm and stabilizing the autonomic nervous system
    • reduces muscular tension, especially in areas such as shoulders, neck, and chest
    • improves the balance between oxygen and carbon dioxide, optimizing stress tolerance
    • supports a more balanced posture thanks to the natural activation of the diaphragm

    It’s no coincidence that many breathing-based practices—from yoga to respiratory physiotherapy—use the same mechanisms observed in laboratory research: slowing the rhythm, expanding thoracic capacity, and engaging the diaphragm.

    What “functional breathing” means

    Functional breathing is not an exotic technique or a complex method: it is the natural way the body is designed to breathe.

    It means breathing:

    • primarily through the nose
    • with the diaphragm leading the inhalation
    • with a calm and continuous rhythm
    • using the full capacity of the rib cage, not just the upper chest

    Researchers from Stanford University and the University of California have shown that diaphragmatic breathing:

    • reduces activity in the amygdala (the brain area linked to the stress response)
    • improves heart–lung interaction, increasing cardiac coherence
    • facilitates emotional and cognitive regulation

    Shallow chest breathing, on the other hand, can increase anxiety, tension, and fatigue, because it activates more “alert-driven” physiological mechanisms.

    How to begin: a simple and powerful exercise

    To take the first steps, it’s helpful to start in a neutral, relaxed, and stable position.
    Many programs, including the one described on this blog, suggest lying down: this way, you don’t need to support your body weight and can focus entirely on your breath.

    Exercise: conscious diaphragmatic breathing

    • Lie on your back, feet on the floor or extended, shoulders relaxed.
    • Place one hand on your abdomen and one on your chest.
    • Inhale slowly through the nose, allowing the hand on your abdomen to rise—your diaphragm is descending and creating space.
    • Exhale calmly through the nose, feeling the hand lower as your body relaxes.
    • Continue for 5–10 minutes without forcing anything, simply observing the natural flow.

    If you wish, you can follow this simple parasympathetic breathing exercise available on BR3ATH.

    After just a few breaths, you realize that functional breathing is a simple, almost primitive act. Yet it is precisely this return to naturalness that triggers deep benefits.

    Several studies—including research published by the National Center for Complementary and Integrative Health—show that just a few minutes of diaphragmatic breathing per day can reduce heart rate, muscle tension, and perceived stress.

    The benefits you may notice

    With consistent practice, even minimal, many people report:

    • a sensation of a wider, freer breath
    • a softer, less “closed” posture
    • greater ability to regain calm after a demanding day
    • improved sleep, thanks to nervous-system regulation
    • increased body awareness

    It’s not magic—it’s physiology. The body immediately recognizes a more natural breath and interprets it as a signal of safety.

    A first step toward a bigger change

    Rediscovering your breath means returning to a simple, human, deeply regulating act.
    Before exploring more specific techniques such as 5-2-5, 4-4-8, or the popular 4-7-8 method, it’s important to reconnect with the basics: calm, diaphragmatic, natural breathing. Many aspects of our balance—from posture to sleep quality, from stress management to symptoms linked to a “short” or dysfunctional breath—depend on this.

    Whether you want to understand the best type of breathing, the most effective position for breathing, or how to identify the signs of poor breathing or dysfunctional posture, everything begins from a single point: listening to the body. And the simplest way to start is precisely the exercise you have just encountered.

    One step at a time, one breath at a time: this is how lasting change is built. And in the next article, we’ll explore how to bring this “rediscovered” breath into everyday life, beginning with its most important channel: the nose.
