Whats actually happening in you when you do Breath-Work and the Pranayama Benefits
Here is a deep dive into our WHY's. Why is there such a buzz about breath-work, why do we do breath-work in our practice here and why is it so beneficial? The first section of this blog is the yogic science. The second section explains the physiological science and benefits taking place in your body when practicing. The third section talks about our Beta, Theta, and Delta states. Your breath-work and pranayama benefits broken down:
INTRODUCTION TO PRANAYAMA & PRANA VAYUS
Prana means life-force energy. Yama means to regulate, direct or bring into alignment. Pranayama, therefore, is the art and practice of bringing our life-force into greater harmony with the natural law.
The yogic tradition understands all manifested reality as intelligent energy. Everything in nature is vibrating - even that which appears completely still. A table retains its “table-ness,” a stone its “stone-ness.” This includes our own body. For form to exist as itself, there must be an underlying intelligence organising it.
This intelligent life-force is what the yogis call prana, also understood as shakti - the dynamic, creative energy of life. Prana is far more than simply “energy.” It is the living intelligence moving through and animating creation.
The doorway to prana is the breath.
Through the breath we begin to refine our perception, our nervous system and our capacity to experience vitality beyond the limitations of the physical body. When yoga is reduced only to the body, we miss its deeper purpose. The body is the doorway, not the destination.
The potential of prana is infinite and working with the breath is only the beginning of pranayama. As the breath becomes conscious and refined, we begin to create the conditions for more prana to move through us. The system becomes more capable of holding and directing this energy, allowing Kundalini - our latent potential - to awaken and move without the body resisting or becoming overwhelmed.
Pranayama also offers a doorway beyond the constant activity of the mind.
When awareness is completely identified with thought, it becomes difficult to experience anything beyond the endless stream of mental activity. Through conscious breathing, we begin to develop the capacity to witness the mind rather than be ruled by it.
This is the experience of no-mind - not unconsciousness, but a state in which awareness is no longer confined to thought.
As this awareness deepens, the light begins to pierce through what yoga calls the darkness of ignorance. We begin to discover that we are not simply the thoughts inside our heads, nor are we limited to the small sense of self we have constructed around them.
Pranayama can open access to chitta - pure consciousness - and to wisdom.
This is where the deeper practices of yoga and kriya begin to reveal their true purpose. Through working with prana, we may experience something beyond the ordinary mind - an experience that reconnects us with our inner intelligence, our wisdom and our inner light.
When we breathe consciously, we are not merely exchanging oxygen. We are consciously working with the movement of life-force within us - expanding our capacity physically, mentally and spiritually.
Without breath, there is no yoga.
The more deeply we understand and practice pranayama, the more deeply we begin to understand ourselves.
From the yogic perspective, yoga can only truly serve our life when it is understood in its fullest expression.
THE PHYSIOLOGICAL SCIENCE AND BENEFITS
When I am teaching advanced pranayama, Kriya breath and modern breath-work, I am not just teaching "energy" alignment - we are aligning the human chemical, neurological and pressure-chamber systems.
The "technology" of the breath relies on the manipulation of Carbon Dioxide (CO₂), blood pH, the vagus nerve and the pressure chambers of the torso. Here is the precise, easy-to-understand breakdown of the physiological mechanics happening inside your systems.
1. The Chemistry: CO₂ and The Bohr Effect
Many people assume breathing is just about getting oxygen (O₂) in and flushing carbon dioxide (CO₂) out as a waste product. In reality, CO₂ is the master key that unlocks oxygen delivery to the body.
The Bohr Effect: Hemoglobin (the protein in red blood cells) holds onto oxygen tightly. It will only release that oxygen into muscles, organs, and brain tissues if CO₂ is present.
Hypocapnia (Low CO₂): When we do fast, cyclic breath-work (like Bhastrika, Kapalbhati or Wim Hof style breathing), you blow off massive amounts of CO₂. This causes blood vessels to constrict (especially in the brain) and causes hemoglobin to hold onto oxygen more tightly. Paradoxically, hyperventilating leads to less oxygen being delivered to the tissues, which is why people get dizzy or feel tingling in their hands (carpopedal spasms).
Hypercapnia (High CO₂ & Retention): When doing holds, (breath retention), CO₂ pools in the blood. This triggers respiratory acidosis (blood pH drops slightly), forcing hemoglobin to dump massive loads of oxygen directly into the tissues. No issues in the tissues!
CO₂ Tolerance Training: By holding the breath, you train the brainstem's chemoreceptors to tolerate higher levels of CO₂. A higher CO₂ tolerance lowers the baseline stress response and keeps the nervous system incredibly calm during daily life.
2. The Mechanics: The "Three Chambers" and Pressure Gradients
The torso functions as a fluid dynamics system divided into two primary chambers by a moving piston: the diaphragm.
When we drop into advanced pranayama, we alter the pressure gradients between these chambers:
The Thoracic Chamber (Chest): Houses the lungs and heart.
The Abdominal Chamber (Belly): Houses digestive organs and major blood vessels (like the vena cava).
The Pelvic Chamber (Floor): Acts as the bottom anchor.
The Respiratory Pump: On a deep inhalation, the diaphragm moves down, increasing pressure in the abdominal chamber and decreasing pressure in the thoracic chamber. This acts like a vacuum cleaner, sucking blood up from the lower body back to the heart.
The Locks (Bandhas): When I cue Mula Bandha (pelvic floor contraction) and Uddiyana Bandha (abdominal draw-in/ navel pumps), you drastically increase intra-abdominal pressure. This compresses the internal organs, alters blood flow and forces cerebrospinal fluid (CSF) upward toward the brain stem, contributing to the "rush" or altered states of consciousness experienced in our Kriya yoga.
3. The Neurological Wiring: Vagal Tone and Stress Inoculation
The way you move your breath acts as a direct software command to your autonomic nervous system.
The Heart Rate Lever: Inhalation temporarily suppresses the vagus nerve, causing the heart to speed up. Exhalation stimulates the vagus nerve, releasing acetylcholine to slow the heart down. This is why extended exhales (like a 4-count inhale, 8-count exhale) immediately induce deep parasympathetic relaxation.
Resonant Frequency: Breathing at roughly 5.5 to 6 breaths per minute aligns your heart rate variations with your breathing rhythm. This creates "cardiovascular coherence," maximising Heart Rate Variability (HRV) and optimising brain-body communication.
Stress Inoculation (Fast Protocols): Rapid breathing activates the sympathetic (fight-or-flight) nervous system on purpose, dumping adrenaline into the bloodstream. By keeping the mind calm while the body is chemically "panicking," you undergo neuro-resilience training. This teaches your brain how to quickly switch off a stress response.
4. Why "Kriya" and Rhythmic Patterns Create Altered States
As all of the regulars here are probably aware of (or anyone who has done kriya breath-work) Kriya breaths often involve specific, rapid, repetitive, circular breathing patterns.
By shifting blood pH through rapid breathing (alkalosis) and then clamping down with holds (Kumbhaka) and Bandhas, you shift the brain out of its normal Default Mode Network (DMN) -the brain network responsible for the ego, time processing, and rumination. When the DMN goes quiet, people experience profound emotional releases, feelings of oneness and deep meditative states.
KRIYA BREATH AND OUR BETA, THETA, DELTA BRAIN STATES
Neuroscientific EEG research explains that the power of somatic practices and rhythmic breathing (like Kriya) lies in its ability to actively shift the brain out of stress-induced states and into restorative neural frequencies.
By changing the rhythm, depth and retention of the breath, you manipulate the central nervous system, effectively changing the literal electrical speed of your brain waves.
A Kriya-based practice orchestrates a clear journey across Beta, Theta, and Delta states:
1. The Starting Point: Calming the "High Beta" State
The Frequency: Beta waves (12 to 30 Hz) are dominant when you are wide awake, alert and engaged in logical thinking, task management, or analytical work.
The Problem: Due to digital overload, most people are trapped in High Beta, which manifests as anxiety, racing thoughts, hyper-vigilance and obsessive mental chatter.
How Kriya Works: Structured, rhythmic breathing acts as an immediate brake pedal. By enforcing conscious regulation of the breath, you quieten the "neural noise" (aperiodic signals) in the prefrontal cortex. It forces the brain to drop out of High Beta execution mode and brings it down into a relaxed, present-moment baseline.
2. The Sweet Spot: Accessing the "Theta" State (Waking Lucid Dream)
The Frequency: Theta waves (4 to 8 Hz) typically occur during deep meditation, light sleep or the twilight zone just before you drift off. It is the gateway to the subconscious mind.
The Experience: This is where the magic happens in breathwork. In a Theta state, your analytical mind steps aside. You experience heightened intuition, vivid mental imagery, deep emotional processing and a sense of timelessness.
How Kriya Works: Clinical EEG studies show that rhythmic, continuous yoga breathing sharply accentuates frontal theta rhythms. By stimulating the vagus nerve and synchronising the left and right hemispheres of the brain, Kriya creates a unique biological phenomenon known as "restful alertness". The brain waves slow down to Theta, but you remain completely conscious, making it highly effective for emotional release and trauma integration.
3. The Deepest Vault: Dropping into the "Delta" State (Yogic Trance)
The Frequency: Delta waves (0.5 to 4 Hz) are the slowest brain waves, normally reserved for dreamless, deep, restorative sleep where cellular healing takes place.
The Experience: In a somatic or Kriya or Yoga Nidra context, entering Delta while awake is a profound state of deep physical immobility and spiritual stillness, often referred to in classical texts as Turiya or Samadhi.
How Kriya Works: During the integration or stillness phases of a session (like a sustained breath retention or dropping into Yoga Nidra at the end), EEG data reveals a sharp rise in Delta amplitude. This creates an intense parasympathetic shift - your physical body enters a state of profound biological rest identical to deep sleep, yet your awareness remains intact. It allows for rapid physiological rejuvenation, psychological processing and a total nervous system reset
You are warmly welcome to experience safely guided Kriya breath here with me, Kali Jade and see what shifts for you. I look forward to sharing space soon. If you are curious to drop into the deeper Delta state we can arrange a private Yoga Nidra 1-1 session. (Also available via Zoom if you can't be here in person) Together, we rise...
