Breathing
Breathing is essential to life and has a profound impact on our overall well-being. Understanding the neural mechanisms behind breathing and its effects on the body is key to utilizing it effectively. By consciously controlling our breath, we can improve our health, mood, learning, and performance. Regulating our breathing enhances our brain's ability to learn, remember information, and regulate emotions. Inhaling is beneficial for learning, while exhaling is important for overall breathing balance. The duration, intensity, and timing of our breaths define our mental and physical state. Fortunately, we have the ability to control our breathing, which allows us to control our mental health, physical health, and performance.
Respiration, Oxygen & Carbon Dioxide
The respiratory system is essential for delivering oxygen to the cells in our body, particularly the brain cells, which require a lot of oxygen. Oxygen cannot diffuse through our skin, so we need to breathe in order to bring oxygen to the deeper cells. Additionally, the respiratory system helps remove excess carbon dioxide from our body. It is important to maintain the correct balance of oxygen and carbon dioxide for optimal mental and physical functions.
- The respiratory system delivers oxygen to cells, especially brain cells.
- Breathing is necessary to bring oxygen to deeper cells.
- The respiratory system removes excess carbon dioxide.
- Maintaining the balance of oxygen and carbon dioxide is crucial for optimal function.
The mechanical and chemical mechanisms of the respiratory system work together to regulate bodily functions.
- Mechanical mechanisms involve neurons in the gut that signal fullness or emptiness of the stomach.
- Chemical mechanisms involve neurons in the gut that detect amino acids, fatty acids, and carbohydrates.
- Mechanical and chemical signals regulate bodily functions.
Understanding the mechanical and chemical aspects of breathing is important for optimal health.

- It can lead to increased calmness, focus, alertness, and altered personality in positive ways.
Breathing Mechanics
Breathing mechanics involve the process of bringing air into the body through the nose or mouth, down the larynx, and into the lungs. The lungs act as a pump, consisting of two large bags that can fill with air or squeeze it out. Inside the lungs are hundreds of millions of small sacs called alveoli, which increase the surface area and allow for more efficient exchange of oxygen and carbon dioxide with the bloodstream. The mechanical aspects of breathing also involve the use of muscles, specifically the diaphragm and intercostal muscles, to expand and contract the lungs.

- The lungs act as a pump, filling with air or squeezing it out.
- Alveoli in the lungs increase surface area for efficient exchange of oxygen and carbon dioxide.
- Muscles like the diaphragm and intercostal muscles expand and contract the lungs.
The diaphragm and intercostal muscles play a crucial role in breathing mechanics. The diaphragm moves down during inhalation, creating more space for the lungs, while the intercostal muscles between the ribs contract, causing the rib cage to move up and expand. These muscles are controlled by the phrenic nerve, originating in the brainstem, which sends signals to move the muscles involved in breathing.
- The diaphragm and intercostal muscles are key players in breathing mechanics.
- The diaphragm moves down during inhalation, creating space for the lungs.
- The intercostal muscles contract, causing the rib cage to expand.
- These muscles are controlled by the phrenic nerve.
Diaphragmatic breathing is considered the most efficient way to breathe. It allows the lungs to expand and contract effectively. To determine if you are using diaphragmatic breathing, observe if your belly moves outward on the inhale and inward on the exhale.
- Diaphragmatic breathing is the most efficient way to breathe.
- It allows the lungs to expand and contract effectively.
- Observe if your belly moves outward on inhale and inward on exhale to determine if you are using diaphragmatic breathing.
Breathing mechanics involve the control of various muscles, such as the diaphragm and intercostal muscles, to bring in and expel air from the lungs. Both diaphragmatic breathing and rib cage breathing can be used effectively to bring in oxygen. The ability to independently control these mechanisms or combine them is crucial for regulating mental and physical states.
- Various muscles, including the diaphragm and intercostal muscles, control breathing mechanics.
- Diaphragmatic breathing and rib cage breathing are both effective for bringing in oxygen.
- The ability to control these mechanisms is crucial for regulating mental and physical states.
Breathing in through the nose is harder than breathing in through the mouth due to increased resistance. However, this increased resistance allows for more force and air to be drawn into the lungs. Breathing in through the nose is beneficial and can help bring more oxygen into the system.
- Breathing in through the nose is harder but allows for more force and air to enter the lungs.
- It is beneficial and helps bring more oxygen into the system.

Chemistry of Breathing, Hyperventilation
Breathing correctly is essential for delivering oxygen to our cells and tissues. Carbon dioxide levels need to be balanced, as too much can induce panic. The amygdala, associated with fear and threat detection, plays a role in this response. Oxygen moves from the air into the alveoli of the lungs and then into the vasculature, where it binds to hemoglobin and is delivered to cells and tissues.
Key points:
- Breathing involves the exchange of oxygen and carbon dioxide in the body.
- Oxygen binds to hemoglobin in the bloodstream, but carbon dioxide is needed to release the oxygen from hemoglobin.
- Carbon dioxide levels affect the acidity of the body, with low levels making the blood more alkaline.
- Hyperventilation is a process where one inhales and exhales more air than usual, leading to the removal of more carbon dioxide from the body.
- Hyperventilation can induce panic and anxiety due to its effect on the excitability of neurons.
- Hyperventilation activates the sympathetic nervous system and releases adrenaline, resulting in increased alertness and autonomic arousal.
- Individuals with anxiety or panic attack tendencies should not attempt hyperventilation.
- Hyperventilation can cause vasoconstriction, tingling sensation in the extremities, and lightheadedness.
- Hyperventilation can lead to hypocapnic hypoxia, characterized by reduced levels of oxygen and carbon dioxide, affecting energy levels, anxiety levels, and blood vessel constriction.
- Maintaining a balance of oxygen and carbon dioxide is important for optimal health and performance.
High Altitudes, Oxygen & Breathing
At high altitudes, breathing becomes more difficult due to lower oxygen levels and air pressure. Key points include:
- Lower oxygen levels at high altitudes make it harder to breathe.
- The lower air pressure at high altitudes requires more effort to fill the lungs with air.
- Changes in atmospheric gases at high altitudes can cause symptoms like lightheadedness and headaches.
- The body can adapt to high altitudes over time, increasing the amount of oxygen carried in the blood.
- Athletes who train at altitude may experience adaptations that improve oxygen delivery to muscles.
- Deliberate breathing techniques like hyperventilation and breath holds can help adapt to high altitudes more quickly.
Tool: Sleep Apnea, Nasal Breathing
Sleep apnea is a condition where individuals underbreathe during sleep, leading to a decrease in oxygen intake. This can result in excessive daytime sleepiness, anxiety, snoring, and serious health concerns such as cardiovascular events, sexual dysfunction, and cognitive dysfunction. Sleep apnea can affect both overweight and non-overweight individuals and is particularly problematic for those with traumatic brain injuries or high levels of stress. One common treatment for sleep apnea is the use of a CPAP device.

- It is more cost-effective and teaches the body to breathe properly.
- Nasal breathing helps train the phrenic nerve, which controls the diaphragm and allows the lungs to fill up.
Brain Centers & Breathing Rhythm
The brain centers that control breathing rhythm are the pre-Botzinger complex and the parafacial nucleus. These centers are responsible for rhythmic patterns of breathing and breathing during activities like speaking. Understanding these centers is important for optimizing breathing techniques.
- The pre-Botzinger complex controls rhythmic aspects of breathing and is involved in breathing during sleep and unconscious breathing. Disruption of its function can lead to conditions like sudden infant death syndrome and deaths related to the opioid crisis.
- The parafacial nucleus is responsible for patterns of breathing with pauses or doubling up of inhales or exhales. Box breathing, a specific pattern of breathing, involves conscious control and relies on the parafacial nucleus.
- By consciously taking control of these brain centers, we can manipulate our breathing patterns and make exhales active instead of passive.
- Proper breathing techniques are important for optimal health, mood, learning, and performance.
Brain, Hyperventilation & “Over-breathing”
Breathing plays a crucial role in controlling brain excitability, and different breathing patterns can impact the brain's ability to respond to stimuli. However, hyperventilation or over-breathing, which involves exhaling too much carbon dioxide, can reduce brain excitability and impair brain function. This is because low carbon dioxide levels prevent oxygen from reaching the brain. Hyperventilation can lead to hyperexcitability in the brain, resulting in increased anxiety and decreased efficiency in detecting things. It can also trigger seizures in seizure-prone patients. Therefore, understanding and practicing proper breathing techniques are essential for optimal brain health, mood, learning, and performance.
What is Healthy Breathing?
Healthy breathing involves taking relatively shallow breaths, about 12 per minute, while avoiding overbreathing. Most people tend to overbreathe, taking anywhere from 15 to 30 shallow breaths per minute. However, if you breathe more deeply, you can achieve the same amount of air intake with only four to six breaths. The key is to focus on nasal breathing, which provides resistance and allows for greater oxygen intake and longer exhalation.
Key points:
- Healthy breathing involves shallow breaths at a rate of 12 per minute
- Overbreathing can be avoided by taking deeper breaths, about 4 to 6 per minute
- Nasal breathing is important for resistance, increased oxygen intake, and longer exhalation
Healthy breathing involves balancing oxygen and carbon dioxide levels in the body. People who breathe in a healthy manner take pauses between breaths, which is important for optimal brain function. Overbreathing can lead to hyperexcitability in the brain, decreased efficiency in learning and focus, and affect pH levels in the body's tissues.
Key points:
- Pauses between breaths are important for optimal brain function
- Overbreathing can lead to hyperexcitability, decreased learning and focus, and affect pH levels
Healthy breathing involves a balance between underbreathing and overbreathing. Research shows that people tend to underbreathe at night and overbreathe during the day.
Key point:
- People tend to underbreathe at night and overbreathe during the day
Tool: Train Healthy Breathing, Carbon Dioxide Tolerance Test & Box Breathing
The most profound aspect of the topic is training healthy breathing and conducting a carbon dioxide tolerance test.
Key points:
- The carbon dioxide tolerance test measures an individual's ability to control their breathing at both the mechanical and chemical level.
- The test involves breathing normally for 10 seconds, then taking a deep breath and measuring the time it takes to exhale until the lungs are empty.
- The purpose of the test is to assess how well an individual manages carbon dioxide and their breathing patterns.
- The test is not related to cardiovascular fitness but can help improve breathing and overall health.
- Box breathing is a breathing exercise that can be done daily to improve breathing efficiency and reduce overbreathing at rest.
- The exercise involves equal duration inhale, hold, exhale, and hold phases, with the duration depending on an individual's carbon dioxide discard rate.
- Box breathing can lead to changes in the resting pattern of breathing and has benefits for health, mood, learning, and performance.
- The carbon dioxide tolerance test can be used to determine the duration and size of the box breathing exercise.
- Practicing box breathing can improve an individual's carbon dioxide discard rate and should be reassessed periodically to track progress.
- The ultimate goal is to achieve deeper and less frequent breathing at rest, and breathing through the nose is recommended.
Tool: Breathwork & Stress Reduction; Cyclic Sighing
Cyclic sighing is a highly effective breathwork technique for reducing stress, improving mood, and enhancing sleep. It involves inhaling deeply through the nose, followed by a second inhale to fully inflate the lungs, and a long exhale through the mouth. Studies have shown that practicing cyclic sighing for just five minutes a day can lead to significant reductions in stress throughout the day. This technique helps restore balance between the sympathetic and parasympathetic nervous systems, inducing a state of calm. Additionally, a single deep sigh can quickly lower stress levels in real time.
Tool: Physiological Sighing & Exercise Side Cramp
Physiological sighing is a double inhale through the nose and extended exhale through the mouth that helps rebalance the oxygen-carbon dioxide ratio in the body. It can be used to reduce stress and align with natural breathing patterns. Proper breathing techniques during exercise can prevent side stitches. The physiological sigh can alleviate right-side side stitches by changing the firing of the phrenic nerve. However, left-side side stitches may be caused by excessive air or fluid in the stomach. Understanding the relationship between breathing, the phrenic nerve, and nearby organs can help manage side cramps during exercise.
Breathing & Heart Rate Variability
The diaphragm plays a crucial role in breathing, affecting heart rate. By understanding this relationship, you can learn to control your heart rate in stressful situations. Breathing techniques, such as respiratory sinus arrhythmia, can be used to manipulate heart rate. Various practices like Wim Hof breathing and Pranayama breathing emphasize inhales or exhales to increase or decrease heart rate. This understanding has been utilized in sports, military, and clinical settings to prevent panic or anxiety attacks. The skill of actively exhaling allows individuals to control their heart rate quickly.
Tool: How to Stop Hiccups
Hiccups can be stopped by preventing the spasm of the phrenic nerve. Here are the key points to stop hiccups:
- Breathing into a bag is one method, but there are other approaches as well.
- Inhaling three times through the nose, holding the breath for 15-20 seconds, and exhaling slowly hypercontracts the phrenic nerve, alleviating hiccups.
- Another technique involves taking three inhales through the nose followed by a long exhale through the nose or mouth, hyperexciting the phrenic nerve.
- Return to normal breathing after performing the technique and repeat if hiccups persist. This method is scientifically supported and efficient.
Tool: Stress Management & Cyclic Hyperventilation, “Wim Hof Method”
Cyclic hyperventilation, also known as the Wim Hof Method, is a breathing technique that involves taking deep breaths through the nose and exhaling through the mouth. This technique increases autonomic arousal and releases adrenaline, allowing for longer breath holds without feeling anxiety or the need to breathe. It is part of a stress management method that also includes deliberate cold exposure and mindfulness. However, caution should be taken near water due to the increased risk of shallow water blackout.
Key points:
- Cyclic hyperventilation involves deep breaths through the nose and exhaling through the mouth.
- It increases autonomic arousal and releases adrenaline.
- It allows for longer breath holds without anxiety or the need to breathe.
- It is part of the Wim Hof Method, which also includes deliberate cold exposure and mindfulness.
- Caution should be taken near water due to the risk of shallow water blackout.
Deliberate Cold Exposure & Breathing
Deliberate cold exposure and breathing are closely linked, as cold water can affect our ability to think clearly. However, by practicing rhythmic breathing during cold exposure, we can maintain control and prevent panicky breathing. This skill can also be applied to other stressful situations in life. Additionally, specific breathing patterns can impact learning and memory.
Tool: Inhales & Learning; Exhales & Movement
Nasal breathing is essential for optimal health, mood, learning, and performance. Inhaling through the nose improves reaction time, memory, and learning ability, while exhaling decreases these functions. It activates specific brain regions involved in learning and memory. Inhaling allows for the intake of chemical information into the brain, enhancing cognitive function. Exhaling, on the other hand, does not have the same effect. Inhaling air through the nose enhances the ability to detect novel stimuli and increases focus and memory encoding. However, it is important to note that inhaling air makes voluntary movements less efficient. Exhalation is important for generating power in activities like baseball and martial arts. Nasal breathing is highly beneficial compared to mouth breathing.
Mouth vs. Nasal Breathing, Aesthetics
Breathing through the nose is recommended for optimal health, as it allows for increased lung inflation, warms and moisturizes the air, and is more favorable for lung health. Nasal breathing also creates nitric oxide, which relaxes smooth muscles and improves blood flow. It is beneficial for relieving congestion and promoting overall tissue health. On the other hand, mouth breathing can be damaging to respiratory functions and can lead to negative effects on facial structure and overall health. Switching to nasal breathing can result in dramatic and favorable aesthetic changes, including elevation of the eyebrows, sharpening of the jaw, and improvements in teeth and jaw structure. Nasal breathing is also beneficial for optimal health, mood, learning, and performance, as it improves nutrient delivery and waste removal in the body. Breathing exercises can help decrease stress, improve sleep and mood, and enhance learning. To determine efficient nasal breathing, a simple test is to close the mouth, place the tongue on the roof of the mouth, and breathe only through the nose. Proper breathwork and deliberate respiration practices can create quick changes and optimal results.
