Breath

The book Breath: The New Science of a Lost Art by James Nestor reveals that breathing - a basic process we perform every day without much thought - is actually one of the most significant factors that influence our health, energy, and long-term vitality. The author guides us through the world of ancient breathing techniques and modern scientific research to show us how proper breathing can transform the quality of our lives. Through stories, research, and his own experiments, he shows us how essential breathing habits are to everyday health and how we can improve them with simple steps.

Breathing is a fundamental yet often underestimated process that has a profound impact on our health and quality of life. Proper breathing through the nose brings many benefits that we have unfortunately largely lost in modern times. The nose is not only a "gateway" to the air, but also an active filter that traps harmful particles and bacteria. It also regulates the temperature and humidity of the air, which is crucial for the optimal functioning of the lungs and the entire respiratory system. The nasal mucosa contains thousands of tiny hairs, which are the body's natural protection against impurities. Due to this "natural air conditioning", the air we breathe in enters the lungs in an ideal state. In addition, when breathing through the nose, a substance called nitric oxide is formed in the body, which has strong anti-inflammatory effects, helps dilate blood vessels and improves blood circulation. Interestingly, this effect only occurs with nasal breathing, whereas mouth breathing does not produce it. Imagine ancient civilisations, such as the ancient Egyptians or Greeks, who knew well the importance of nasal breathing. Archaeological findings have also been preserved that show that people in these periods had strong jaws and regular teeth, which scientists attribute to proper breathing and an overall way of life. It is the increasing dental problems in modern times, such as clenched teeth or narrow jaws, that may be related to mouth breathing. The importance of nasal breathing is also emphasised by many cultures and religions. Yoga and Pranayama, for example, consider breathing to be a bridge between the body and the mind. They teach that control over breathing through the nose not only contributes to mental well-being, but also to physical health. Modern science confirms this wisdom, as proper breathing can stabilize blood pressure, reduce stress, and promote overall health. Nowadays, when we spend a lot of time in heated or air-conditioned rooms, we often don't even notice how inefficiently we breathe. Intentionally practicing proper breathing through the nose can be a simple step, but one that has a profound impact on our lives.

Mouth breathing, although it looks innocent, can have serious consequences for our health. This habit, which many people unknowingly adopt, often starts in childhood. The cause may be a blocked nose or an improperly formed breathing habit. Although the mouth seems to be a simple alternative to the nose, it cannot provide proper filtering and humidification of the air, which puts a strain on the respiratory system. When breathing through the mouth, mucous membranes are more likely to dry out, weakening the natural protection of the airways against bacteria and viruses. Regular mouth breathing can cause recurrent infections, allergies and asthma. This way of breathing fails to promote the body's production of nitric oxide, which is important for dilating blood vessels and promoting circulation, thus reducing the body's oxygenation efficiency. The impact of mouth breathing is also reflected in the quality of sleep. People who mouth breathe during the night often suffer from sleep apnoea, which means that the airways are partially or completely blocked, causing an inadequate supply of oxygen to the body. This problem manifests itself in snoring, frequent awakenings, or fatigue that persists throughout the day. Lack of quality sleep has long-term effects on physical and mental health, including impaired concentration and increased risk of chronic diseases. Mouth breathing can even affect facial and dental development, especially in children. If mouth breathing becomes the norm at an early age, it can lead to narrow jaws, irregular tooth alignment and overall changes in facial appearance. Scientists have already proven that this way of breathing weakens the muscles of the jaw and face, which ultimately affects the position of the tongue and the shape of the face. There is also evidence of the impact of mouth breathing on psychological well-being. Lack of oxygen, which the body receives efficiently through nasal breathing, can affect stress levels and mood. In fact, mouth breathing causes faster and shallower breaths, which can signal stress to the body and trigger the production of stress hormones such as cortisol. Learning to breathe through the nose seems like a simple step, but it requires conscious effort and discipline. Through small steps, such as practicing deep nasal breathing or deliberately closing your mouth during the day, a natural way of breathing can be restored that contributes to overall health and vitality.

Slow and conscious breathing is key to calming the body and mind, while having a profound physiological effect on our health. A rhythm of approximately 5 to 6 breaths per minute is considered ideal for achieving a balance between the sympathetic and parasympathetic nervous systems, which improves not only overall well-being, but also organ efficiency and regeneration. Such breathing allows us to better cope with stressful situations and strengthen internal stability. Research has shown that slow breathing can help lower blood pressure and slow the heart rate. This effect is especially important for people who face daily stress or suffer from anxiety. When we are stressed, our breathing becomes shallow and rapid, which activates the sympathetic nervous system - the mechanism that signals the body to "fight or flight." Slow breathing, on the other hand, activates the parasympathetic system, which helps the body relax, restore balance, and promote digestion. An interesting example is a technique used in Japanese Zen meditation that focuses on slow exhalation. In Zen monasteries, monks are advised to breathe deeply and slowly while meditating, with an emphasis on long exhalations. This approach not only promotes inner peace, but is also an effective remedy for insomnia caused by tension or constant thinking. Slow breathing thus becomes a pathway to relaxation as well as better concentration. The effects of slow breathing have also been demonstrated in the so-called heart rate variability (HRV), an indicator of stress resistance. The higher this variability, the better the body can cope with stressful situations. Regular practice of slow breathing increases HRV and thus strengthens the body's ability to recover from stressful events. Slow breathing also has a positive effect on blood oxygenation as it allows the lungs to use oxygen more efficiently. By breathing slower and deeper, we give the body the opportunity to absorb more oxygen and remove carbon dioxide, which contributes to better brain function and concentration. In practice, slow breathing can easily be incorporated into daily life. For example, just spend a few minutes a day practicing deep breathing - inhaling for four seconds, holding the breath, and then exhaling for six to eight seconds. Such exercises have an immediate effect on reducing stress and bringing a sense of calm that can last for hours. By using slow breathing, we can create a space for ourselves where we are able to respond calmly and consciously even in challenging situations. This simple habit can be a small but powerful tool for many people on the path to equanimity and a healthier, more harmonious life.

Deep diaphragmatic breathing, also known as abdominal or diaphragmatic breathing, is a technique that takes breathing to a whole new level. Instead of superficial breaths into the top of the lungs, deep diaphragmatic breathing involves the full use of the diaphragm - the muscular organ under the lungs that, when breathed properly, allows the lungs to fill with more air. This way of breathing promotes body recovery, reduces stress and improves overall performance. Biologically, diaphragmatic breathing optimizes the transfer of oxygen to the blood and helps eliminate carbon dioxide from the body. With everyday stress, we often resort to shallow breathing into the upper chest, but this does not allow us to make sufficient use of our lung capacity. Diaphragmatic breathing, on the other hand, brings calmness and relaxation while effectively activating the parasympathetic nervous system, which reduces levels of stress hormones such as cortisol. Many athletes and professional athletes use diaphragmatic breathing to maximize performance. During intense exercise, efficient use of oxygen is essential for maintaining endurance and preventing exhaustion. For example, elite runners often practice diaphragmatic breathing to cover long distances without excessive panting. Diaphragmatic breathing helps them regulate exertion and improve muscle oxygenation. In addition to the physical benefits, deep breathing also has a powerful psychological effect. It helps relieve anxiety and promote concentration, which is crucial in everyday life and in work situations. During diaphragmatic breathing, endorphins are released into the bloodstream, which promote a good mood and feelings of well-being. In this way, deep breathing can become a powerful tool in the fight against stress and anxiety. Deep breathing is also used in various therapeutic techniques such as meditation and mindfulness, where it serves to calm the mind. Psychologists and therapists often recommend their clients to practice deep breathing as it can help in coping with emotional fluctuations and in reducing symptoms of depression. Practicing diaphragmatic breathing is simple and can be part of a daily routine. To start, it is enough to take a few minutes a day to pay attention to your breath and breathe slowly and deeply into your abdomen. For example, you can try a breathing exercise where inhaling is done for four seconds, holding the breath for another four seconds, and exhaling for six to eight seconds. Ultimately, diaphragmatic breathing contributes not only to better physical health, but also to inner balance and emotional stability. Although it is a simple habit, it has a profound effect on quality of life because it brings body and mind together in harmonious balance.

Exhalation, although often overlooked, is just as important as inhalation and has significant health benefits. When breathing properly, exhalation is an active process that serves to remove carbon dioxide from the body. By paying attention to exhaling fully and consciously, we help the body maintain an optimal balance between oxygen and carbon dioxide. If carbon dioxide is not sufficiently removed from the body, it can lead to excessive carbon dioxide accumulation, causing acidosis and general discomfort. During conscious exhalation, the parasympathetic nervous system, which is responsible for relaxing the body and reducing stress, is activated. This process is crucial for calming the nervous system and overall physiological balance. A longer, calm exhale is an effective way to relieve stress and promote feelings of calm. It is also often used in therapies and techniques aimed at managing anxiety, where conscious exhalation brings a calming effect. At the same time, conscious and deep exhalation promotes better ventilation of the lungs and aids in their effective regeneration. This principle is key for people with respiratory problems such as asthma or chronic obstructive pulmonary disease, where it is important to minimise air retention in the lungs. Techniques focusing on prolonged exhalation can help these patients improve breath control and relieve symptoms. The importance of exhalation is also important in sports, where proper breathing allows for more efficient use of energy. Athletes and sportspeople practice prolonged exhalation techniques, which allows them to maximize performance and recover more quickly after physical exertion. Prolonged exhalation reduces pressure in the body and promotes more efficient use of oxygen, which is critical for endurance activities. An interesting example is the box breathing technique, which is used in a variety of professions, from soldiers to top executives facing high-stress situations. This technique involves a controlled inhalation, holding the breath, exhaling and then holding the breath, with the emphasis being on just a slow and thorough exhalation that relaxes the body. Proper exhalation is also important for maintaining healthy blood pressure. With a longer exhalation, mechanisms that lower blood pressure and promote healthy circulation are activated. This effect is especially beneficial for people with hypertension, who can use breathing exercises to achieve tension reduction and promote heart health. We may not notice the importance of exhalation, but it is the foundation for balanced and effective breathing. Conscious and controlled breathing with an emphasis on exhalation is an approach that helps us gain control over our bodies, emotions and overall health.

Pranayama, the ancient Indian discipline of breath work, focuses on conscious control of breathing to harmonize the body and mind. Pranayama is the cornerstone of yoga, where the breath is seen as a stream of energy (prana) that flows through the entire body, enlivening all its functions. This breathing technique, practiced for thousands of years, is now used not only to calm the mind, but also to physically heal the body and better manage stress. Pranayama encompasses different forms of breathing, each with unique effects. For example, a technique called Nadi Shodhana, or alternate breathing through the nostrils, is used to harmonize the right and left hemispheres of the brain, contributing to inner balance and mental clarity. In this technique, one first inhales slowly through one nostril while the other is closed, and then exhales just as slowly through the other. This approach helps calm the nervous system and is ideal for anyone who wants to relieve anxiety or increase focus. Another important technique is Kapalabhati, or "fire breathing," which consists of quick, sharp exhalations and relaxed inhalations. Kapalabhati is considered a cleansing technique because it stimulates digestion, removes toxins, and promotes blood circulation. This technique is often used to increase energy and vitality, as it activates the body and mind, which can be very helpful before physical activity or mental exercise, for example. However, pranayama is not just about mastering breathing techniques; it is also a spiritual discipline. Ancient Indian texts such as the Hatha Yoga Pradipika state that pranayama is a way to control the mind and emotions. The goal of this practice is not only physical health, but also spiritual development, where the breath serves as a bridge between the outer and inner worlds. Through pranayama, an individual can experience a deep inner peace and harmony that transcends everyday worries. The benefits of pranayama are confirmed by modern science. Studies show that the regular practice of pranayama can improve respiratory health, boost immunity, and even alleviate symptoms of depression and anxiety. Researchers have found that certain forms of breathing can reduce levels of cortisol, the stress hormone, and increase levels of endorphins, contributing to better mood and psychological well-being. In today's often hectic and stressful lifestyle, pranayama is a way to stop, focus and breathe mindfully. This practice offers simple yet powerful tools to let go of stress while deepening your connection with yourself. By paying attention to the breath and becoming aware of its power, we can discover the path to a deeper and more meaningful life.

The Wim Hof Method, also called the "ice man method," has gained popularity as an effective way to strengthen the body and mind through breathing exercises, hardening, and mental concentration. Wim Hof, a Dutch extreme athlete, has tested the limits of human capabilities by breaking records for surviving extremely cold conditions, including staying in icy water or climbing Mount Everest in shorts. The method is based on the concept of hormesis, a process whereby exposing the body to controlled stress promotes its resilience and adaptation to harsh conditions. One of the basic elements of the Wim Hof method is deep, intense breathing. This method of breathing consists of several rapid, deep breaths in and out followed by a short breath hold. This cycle of breathing is designed to increase oxygen levels in the body, which helps to increase energy, boost immunity, and relieve the feeling of cold. Although this way of breathing may seem simple, it has profound effects on the physiology of the body, as it can change the pH level of the blood and improve the oxygen supply to the organs. The second key element is exposure to cold, such as immersion in ice water or cold showers. Hardening encourages the production of brown adipose tissue, which the body uses to generate heat and burn calories. Regular exposure to cold strengthens the immune system, improves circulation and aids in muscle recovery. Additionally, when exposed to extreme cold, endorphins are released, which improve mood and help manage stress. Hormesis, the principle on which this method is based, can be understood as the body's adaptation to mild stressful stimuli, which in the long run leads to enhanced health. An example of hormesis in everyday life is exercise - during training the body experiences stress, but over time it builds up resilience and becomes stronger. The Wim Hof Method applies this concept to extreme conditions and thus allows to strengthen both physical and mental resilience to stressful situations. Scientific studies have confirmed that the Wim Hof Method can influence the immune system and reduce inflammation in the body. Research from Radboud University has shown that practising it leads to an increase in the production of anti-inflammatory proteins and reduces the incidence of symptoms of inflammation, which is particularly beneficial for people suffering from autoimmune diseases. These effects are one of the reasons why the method has become popular among athletes and people looking for a way to boost their health in natural ways. The Wim Hof Method is a unique approach that combines ancient techniques with a modern understanding of human physiology. The regular practice of breathing and hardening can help individuals not only manage physical stress, but also psychological tension, giving them the tools to achieve greater inner strength and balance. This method can be a way for many to transcend their own limits and find new levels of vitality and resilience.

Proper breathing habits play a key role in long-term health and vitality. However, most of us breathe shallowly and quickly, often through our mouths, which reduces the body's oxygenation efficiency and can lead to a variety of health problems. When we learn to consciously breathe slowly and deeply through our nose, we can improve the overall quality of our health, reduce the risk of chronic disease, and promote respiratory health. Prolonged breathing through the nose helps us maintain proper moisture in the lungs and supports the body's natural defenses against bacteria and viruses. The nose filters the air, regulates its temperature and traps dust and other impurities that might otherwise enter the lungs. By breathing regularly through the nose, we can prevent frequent inflammation of the airways, which is caused by dirt and dryness of the mucous membranes when breathing through the mouth. Proper breathing also has a positive effect on the cardiovascular system. When we breathe deeply and slowly, our heart rhythm stabilizes, resulting in improved blood pressure and better circulation. This effect is particularly beneficial for people suffering from high blood pressure or anxiety, as deep breathing helps to relax the blood vessels and promotes calm states of mind. Breathing also has an effect on metabolism. When we are stressed or nervous, we often resort to shallow breathing, which speeds up the heart rate and increases levels of cortisol, the stress hormone. High levels of cortisol can negatively affect our metabolism in the long term, which can lead to weight gain or metabolic diseases. Consciously controlled, slow breathing can help regulate cortisol, thereby promoting a healthy weight and proper digestive function. Breathing during physical activity is also key. During sports or strenuous physical activities, nasal breathing helps use oxygen more efficiently, allowing the body to maintain endurance and performance without rapid fatigue. Athletes and coaches often stress the importance of rhythmic and deep breathing for better performance and injury prevention. Research shows that proper breathing also has a positive effect on longevity. Long-term breathing habits affect the health of our lungs and overall oxygenation of our cells, which is critical for maintaining vitality in older age. Additionally, mindful breathing improves mental health, reduces anxiety, and promotes better quality sleep, which is essential for long-term physical and mental health. Therefore, investing in good breathing habits is a simple yet highly effective way to maintain your health. Mindful breathing leads us to a better understanding of our own bodies and provides us with the opportunity to improve our quality of life in a natural and accessible way.

Nestor's book provides a surprising insight into breath as a means of improving our physical and mental health. Through practical advice and understanding of techniques such as nose breathing, slow and deep breathing, and methods of hardening, the author shows how to develop better breathing habits. Breath is more than just a guide to techniques - it is a reminder that breathing is an essential tool we have at our disposal every day. By consciously changing our breathing habits, we can strengthen our health, prolong our vitality, and achieve a sense of inner balance that improves our quality of life. Do you have feedback for us?
