  • Nasal Breathing

    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.

    One breath at a time.

  • 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.

    functional breathing

    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.

    diaphragmatic breathing

    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.

  • Exhaling through the Nose (and not through the Mouth)

    Exhaling through the Nose (and not through the Mouth)

    When we talk about nasal breathing, we usually think of inhalation, but exhaling through the nose (and not through the mouth) also has profound effects on the body. It’s not just a matter of style — it’s physiology.

    exhale

    Exhaling through the nose is more than a good habit: it’s a genuine health strategy. This simple action helps regulate blood pressure, calm the nervous system, and improve oxygenation. In other words, exhaling through the nose is good for you.

    Nitric Oxide: The “Intelligent” Gas of Breathing

    The nasal cavities produce nitric oxide (NO), a molecule that:

    • Dilates blood vessels, improving circulation and blood pressure;
    • Increases oxygenation of the blood;
    • Has a natural antimicrobial effect.

    When you exhale through your nose, part of this NO remains active in the airways, helping to keep them healthy and well-ventilated.

    Slow Exhalation Calms the Body and Mind

    Exhaling through the nose creates a natural resistance to airflow. This slows down exhalation, keeps the balance between oxygen and carbon dioxide stable, and reduces the risk of hyperventilation — a core principle of the Buteyko method.

    Moreover, a long exhalation stimulates the parasympathetic nervous system, which promotes relaxation, digestion, and recovery.
    That’s why, when you exhale slowly through your nose, you feel calm and centered: your breath is literally speaking to your nervous system.

    exhale

    Warmth, Humidity, and Natural Protection

    The nose works as a filter and heat exchanger: during exhalation it retains part of the air’s moisture and warmth, protecting the respiratory tract from dryness and irritation.
    In contrast, exhaling through the mouth cools and dries the air, reducing the protective function of the nasal mucosa.

    In Summary

    Exhaling through the nose:

    • Stimulates the production of nitric oxide, with positive effects on blood pressure and oxygenation;
    • Activates the parasympathetic system, promoting relaxation and calm;
    • Maintains respiratory balance and reduces hyperventilation;
    • Protects the airways from dryness and irritation.

    Try a simple experiment: during the day, notice how often you exhale through your mouth. Then, for a few minutes, try exhaling only through your nose, slowly and mindfully. You’ll notice your body relax and your mind become clearer. If you like, try the guided exercise on parasympathetic breathing.

    A simple gesture. A more complete breath.

    Selected Scientific References

  • The Effects of Coherent Breathing on heartbeat

    The Effects of Coherent Breathing on heartbeat

    In this article, I share the results of a personal at-home experiment in which I tested the effects of coherent breathing on HRV (Heart Rate Variability), using monitoring tools and a dedicated app.

    respirazione coerente e hrv (coherent breathing and HRV)

    Further down, you’ll also find a demonstration video documenting the test in real time—a visual comparison between my heart activity in a normal state and during coherent breathing.

    The results? Clear, interesting, and perfectly aligned with scientific literature.

    What is HRV?

    HRV measures the fluctuations in heartbeats over time. Even if we assume a heart rate of 60 beats per minute—one beat per second—in reality, the time between each beat varies slightly. The higher this variability, the more adaptable and resilient our autonomic nervous system is to internal and external stimuli—making it a key indicator of both physical and mental health.

    What is Coherent Breathing?

    Coherent breathing is a simple yet powerful technique involving a balanced and regular breathing rhythm, where inhalation and exhalation are of equal length—typically around 5.5 seconds each (about 6 breaths per minute). This rhythm helps generate a state of cardiac coherence, in which heart rate and breathing become synchronized, with beneficial effects on overall well-being.

    The Data Speaks for Itself

    During my presentation on coherent breathing, I shared a chart from the study “A smartphone-based cardiac coherence biofeedback system” by Julien De Jonckheere, which clearly illustrates how coherent breathing impacts HRV. On the left side of the graph, where the subject was breathing normally, the HRV pattern appears irregular. On the right side, where the subject engaged in coherent breathing, the pattern becomes smooth and sinusoidal—evidence of heart-respiration synchronization.

    respirazione coerente e hrv (coherent breathing and HRV)

    My Personal Experiment

    Fascinated by these findings, I decided to replicate the experience at home using a Polar H10 chest strap paired with the Elite HRV app. I first carried out normal daily activities, then followed a 5-5 coherent breathing exercise (5 seconds inhale, 5 seconds exhale) from the web app BR3ATH.
    The results were striking: during the coherent breathing phase, my heart rate pattern became periodic—just like in the study.

    respirazione coerente e hrv (coherent breathing and HRV)

    The video clearly shows what the study’s graph illustrates: during the first minute, my breathing was normal and the HRV trace irregular. In the second minute, as I began coherent breathing, the HRV trace turned into a smooth, regular pattern.
    In the still image taken from the video, the HRV periodicity is clearly about 10 seconds, which matches the rhythm of the breathing (one breath every 10 seconds).

    A Small Act, A Big Impact

    Coherent breathing is an accessible practice with profound effects on health. Just a few minutes a day can help your body enter a state of balance and calm.

    The benefits? Greater mental clarity, reduced stress, improved emotional regulation.

    The Importance of Breathing

    Breathing is an automatic bodily function, but when controlled consciously, it can positively influence the nervous system. Slow, controlled breathing helps to:

    • Balance the Nervous System: Deep breathing stimulates the parasympathetic system, counteracting stress responses.
    • Improve Oxygenation: A steady flow of oxygen enhances brain function and helps reduce tension.
    • Enhance Body Awareness: Focusing on the breath induces a state of mindfulness, promoting greater awareness of one’s body and emotions.

    Breathing Exercises: An Accessible Approach

    Breathing exercises require no special equipment or environment—just a quiet space and a few minutes of practice each day. Some examples include:

    • Deep Breathing: Slowly inhaling through the nose, fully filling the lungs, and exhaling just as slowly (as in coherent breathing)
    • Box Breathing: A method that divides the breath into four equal phases, useful for achieving calm and focus.
    • Customized Techniques: Patterns such as 5-2-5 or rhythmic variations that, while different in detail, share the common goal of regulating and slowing down breathing.

    Benefits for Anxiety Management

    Regular breathing exercises offer several specific benefits for managing anxiety:

    • Tension Reduction: Deep breathing helps lower cortisol levels, the stress hormone, promoting relaxation.
    • Improved Emotional Resilience: Conscious breathing aids in recognizing and managing emotions, enhancing the ability to handle stressful situations.
    • Increased Focus: Better oxygenation of the brain stimulates cognitive functions, making it easier to maintain concentration and reduce anxious thoughts.
    • Self-Regulation of the Body: Short 5-10 minute sessions help the body enter a state of balance, making it easier to face daily challenges with serenity.

    Incorporating Breathing into Daily Routine

    To maximize benefits, integrating breathing exercises into specific moments of the day is recommended:

    • Morning: Starting the day with a short session can set a positive tone.
    • During the Day: In moments of stress, taking a few minutes for mindful breathing can help restore balance.
    • Before Bed: An evening session promotes relaxation and improves sleep quality.

    Conclusion

    Breathing exercises are a natural, simple, and accessible remedy for managing anxiety. By dedicating just 5-10 minutes a day to conscious breathing techniques, you can significantly improve mental and physical health, promoting well-being, calmness, and resilience in the face of daily challenges. Trying it is the first step toward greater inner harmony and a better mind-body balance.

  • Coherent Breathing

    Coherent Breathing

    Coherent breathing is a deep breathing technique that promotes the induction of the cardiac coherence state. It is a simple yet highly effective method that can be practiced by anyone to improve their physical and mental well-being.

    Respirazione coerente - Coherent breathing

    The contents of this page are also summarized in the presentation on coherent breathing, given during the meeting held on April 4th.

    What is Cardiac Coherence

    Cardiac coherence, also known as the control of heart rate variability (HRV), is a relaxation and self-regulation technique for the autonomic nervous system. Through deep and mindful breathing exercises—often combined with visualization—it is possible to positively influence heart rate, making it more regular and harmonious.

    HRV: Heart Rate Variability

    When we talk about heart rate, we often imagine that the heart beats at a perfectly regular rhythm, like a clock—e.g., 60 beats per minute, one every second. In reality, the heart doesn’t function so mechanically: there are small variations between one beat and the next, sometimes slightly longer, sometimes shorter.

    These variations—measured in milliseconds—are what we refer to as HRV. A high HRV indicates a responsive and efficient cardiovascular system, capable of quickly adapting to different demands (like starting to run, dealing with stress, or relaxing). On the other hand, a low HRV may suggest less flexibility and greater difficulty responding to stimuli.

    An Experiment

    In the experiment graph , two distinct phases can be observed: in the first part, the HRV trace is irregular and chaotic; in the second, it becomes orderly and rhythmic. The turning point occurs when the subject begins to breathe following a coherent breathing pattern at 0,1 Hz: 6 breaths per minute, or one full cycle every 10 seconds.

    (A smartphone based cardiac coherence biofeedback system - Julien De Jonckheere

    At this rhythm, the subject inhales for 5 seconds and exhales for another 5, creating a regular wave in the heart rate variability trace. The article The Effects of Coherent Breathing on Heartbeat presents the results of my HRV experiment and includes a video showing real-time data.

    How to Practice Coherent Breathing

    Coherent breathing involves deep, controlled breathing in which the inhalation and exhalation phases are of equal duration, typically between 4 and 7 seconds each.

    According to author and researcher James Nestor, in his book “Breath”, the ideal duration for each phase (inhale and exhale) is about 5.5 seconds. This leads to a breathing frequency of about 5.5 breaths per minute, which is considered optimal for achieving physical and mental benefits.

    The Benefits of Coherent Breathing

    The benefits of coherent breathing are numerous and span various areas of health:

    • Cardiovascular benefits: improved efficiency of the heart and circulation.
    • Stress and anxiety reduction: activation of the parasympathetic nervous system, responsible for relaxation.
    • Better sleep: deep and slow breathing promotes restful and high-quality sleep.
    • Overall physical well-being: the regular oxygen flow allows organs—especially energy-demanding ones like the brain—to receive a steady and efficient energy supply.
    • Increased mental clarity: better brain oxygenation leads to improved focus, mental clarity, and learning capacity.
