The Ancient Science of Pranayama
Pranayama originates from two Sanskrit roots: “prana,” meaning vital life force energy, and “ayama,”literally means dimension. So pranayam means moving inthe dimension of Prana (Or the subtle). This sophisticated practice encompasses far more than simple breathing exercises—it represents a complete system for harnessing and directing the subtle energy that animates all life.
According to ancient Vedic understanding, prana flows through 72,000 subtle channels (nadis) in the energy body, converging at seven primary energy centers (chakras). When prana flows smoothly with high levels, the mind remains calm, positive, and enthusiastic. However, disrupted prana flow can lead to physical ailments, emotional imbalances, and spiritual stagnation.
The Science of Breath: Bridging Ancient Wisdom and Modern Research
Breathing involves diaphragm contraction for oxygen intake and CO2 release, regulated by sympathetic/parasympathetic systems. The ancient yogis’ understanding of breath has been validated by modern science. The breath is intricately linked to the autonomic nervous system, which has two main branches:
- Sympathetic Nervous System: The “fight or flight” response, activated by stress.
- Parasympathetic Nervous System: The “rest and digest” response, responsible for relaxation.
When we are stressed or anxious, our breathing becomes fast and shallow, activating the sympathetic nervous system. In contrast, deep, slow breathing techniques, as found in pranayama, stimulate the vagus nerve, a key component of the parasympathetic system. This stimulation sends a signal to the brain that we are safe, reducing heart rate, lowering blood pressure, and decreasing the production of stress hormones like cortisol.
A 2017 study in the journal Frontiers in Psychology highlighted that slow-paced breathing exercises can significantly improve heart rate variability (HRV), a key indicator of a healthy and resilient nervous system. By mastering our breath, we essentially gain a remote control for our nervous system, allowing us to consciously shift from a state of stress to a state of calm.
Scriptural Foundations and Historical Context
In ancient scriptures, pranayama’s essence traces to the Vedas and Upanishads.
Pranayama is the fourth of the eight limbs of yoga, as described by the sage Patanjali in the Yoga Sutras. It is the practice of controlling the prana, or life-force energy, within the body. While breath is a key component, prana is a more subtle, all-encompassing energy that flows through invisible channels called nadis.
The Bhagavad Gita (Chapter 4, Verse 29) describes pranayama practitioners: “Some offer the incoming breath into the outgoing breath, and the outgoing breath into the incoming breath, restraining the paths of both breaths, intent on breath control.”
The Chandogya Upanishad portrays prana as sustaining life, influencing mood and health. Blocked flow leads to negativity; balanced prana fosters positivity.
Brihadaranyaka Upanishad (hymn 1.5.23) references breath control as a path to vitality, relevant today amid rising respiratory issues.
In Patanjali’s Yoga Sutras (2.49), pranayama is defined as “stopping the flow of inhalation and exhalation,” while sutra 1.34 states that mental steadiness “may also result from the exhalation and retention of breath.”
Ancient texts, like the Hatha Yoga Pradipika, detail various pranayama techniques as a means to purify the body and mind, preparing the practitioner for deeper states of meditation. At its core, every pranayama practice involves three stages:
- Puraka (Inhalation): The act of consciously drawing breath in.
- Kumbhaka (Retention): Holding the breath for a period.
- Rechaka (Exhalation): The controlled release of breath.
“When the mind is still, it gets the power to fulfill any thought.”
— Gurudev Sri Sri Ravi Shankar
Key Sutras on Pranayama:
- Sutra 2.49: “Tasmin sati shvasa prashvasayor gati vicchedah pranayamah” “When that (asana) is accomplished, pranayama is the cessation of the movement of inhalation and exhalation”
- Sutra 2.50: “Bahyabhyantara stambha vrittir desha kala sankhyabhih paridrishto dirgha sukshmah” “It has three movements: external, internal, and restrained. Regulated by place, time, and number, it becomes prolonged and subtle”
- Sutra 1.34: “Pracchardana vidharanabhyam va pranasya” “Mental steadiness can also be achieved through the exhalation and retention of breath”
How does Modern Science look at Pranayama?
Recent systematic reviews published in peer-reviewed journals demonstrate that pranayama (yogic breathing) has demonstrated numerous beneficial health effects, with millennial breathing exercises known to induce meditative states, reduce stress, and increase lung capacity. The fortune companies like Google, Apple, Nike now integrate pranayama in employee programs.

Pranayama Techniques
The variety of pranayama techniques is vast, with each designed to produce a different effect. Here, we’ll explore some of the most prominent ones in detail.
1. Nadi Shodhana Pranayama (Alternate Nostril Breathing)
Sanskrit Meaning: “Nadi” (channel) + “Shodhana” (purification)
Nadi Shodhana is a cornerstone of pranayama. “Nadi” means channel, and “shodhana” means purification. It’s believed to cleanse the 72,000 nadis, ensuring a balanced flow of prana. This technique is particularly effective for balancing the body’s two primary energy channels, the ida (lunar) and pingala (solar) nadis, which correspond to the left and right brain hemispheres.
How to Practice:
- Sit in a comfortable, meditative posture with your spine straight.
- Use dhyan mudra: fold index and middle fingers, use thumb and ring finger
- Use your right thumb to gently close your right nostril.
- Inhale deeply through your left nostril.
- At the peak of the inhalation, close your left nostril with your ring finger.
- Exhale slowly through your right nostril.
- Inhale through the right nostril.
- Close the right nostril and exhale through the left.
- This completes one full round.
Physiological Benefits:
- Balances sympathetic and parasympathetic nervous systems
- Harmonizes left and right brain hemispheres
- Regulates all three doshas (Vata, Pitta, Kapha)
- Enhances concentration and mental clarity
Therapeutic Applications:
- Anxiety and stress disorders
- Sleep disturbances
- High blood pressure
- Mental agitation
While generally safe, individuals with a cold, flu, or any nasal blockage should avoid this practice until they can breathe freely through both nostrils. This prevents forcing the breath and irritating the nasal passages.
2. Bhastrika Pranayama (Bellows Breath)
Bhastrika, or Bellows Breath, is a dynamic, energizing technique that involves a series of rapid, forceful inhales and exhales. It’s designed to generate heat in the body, boost energy, and cleanse the respiratory system. It’s especially beneficial for those feeling lethargic or sluggish. However, due to its intensity, it should always be practiced on an empty stomach and under the guidance of a trained teacher
How to Practice:
- Starting Position: Sit comfortably in a meditative posture like Vajrasana (diamond pose) or Sukhasana (cross-legged position). Keep your spine straight and your shoulders relaxed.
- Arm Position: Make a fist with both the hands and keep it in front of the shoulders with the palms facing forward. The elbows are close to the body.
- Inhale: Inhale deeply and forcefully through your nose, raising your arms straight up above your head. As you raise your arms, open your fists.
- Exhale: Exhale slightly forcefully through your nose, bringing your arms back down to the starting position with your fists closed.
- Rhythm: Continue this rhythmic motion of inhaling and raising your arms, and exhaling and lowering your arms.
- Rounds: A typical round consists of about 20 breaths.
- Relaxation: After one round, place your palms on your thighs, facing up, and take a few normal breaths. Feel the energy circulating in your body.
- Repetitions: Repeat for two more rounds.
Important Considerations
- Pace: Start at a slow to moderate pace and gradually increase it as you become more comfortable.
- Empty Stomach: It is best to practice Bhastrika on an empty stomach.
- Contraindications:
Due to its intense and rapid nature, Bhastrika is contraindicated for individuals with:
- High blood pressure or hypertension.
- Heart conditions or a history of heart disease.
- Hernia or stomach ulcers.
- Vertigo or dizziness.
- Pregnancy.
- Glaucoma.
- Any recent abdominal surgery. It should always be practiced on an empty stomach.
- Guidance: As with any advanced pranayama, it’s best to learn this technique under the guidance of a Sri Sri Yoga Teacher to ensure correct form and avoid strain.
Benefits:
- Increases lung capacity and oxygen delivery
- Generates internal heat (agni)
- Energizes the entire system
- Improves digestion and metabolism
Precautions:
- Avoid in hypertension, heart conditions, and hernia
- Practice on an empty stomach only
- Stop if dizziness occurs
3. Bhramari Pranayama (Humming Bee Breath)
If you’re feeling overwhelmed or anxious, Bhramari, or Humming Bee Breath, can be a powerful tool for finding inner peace. This practice involves making a soft, humming sound on the exhale, which creates a gentle vibration in the head. This vibration has a profoundly calming effect on the nervous system. According to a study in the Journal of Alternative and Complementary Medicine, Bhramari Pranayama has been shown to reduce blood pressure and heart rate, making it a powerful technique for stress management, particularly beneficial for hypertension and mental agitation.
How to Practice:
- Sit in a comfortable position with the spine erect
- Place the index fingers on the ear cartilage (Tragus) with the elbows in line with the shoulder
- Now, Inhale through the nose and as you exhale, hum like a bee pressing your index finger in and out on the tragus.
- Feel vibrations in the head and chest
- Repeat 5-6 times
Benefits:
- Calms the nervous system and reduces stress
- Lowers blood pressure
- Improves concentration
- Beneficial for hypertension and anxiety
This practice is generally very safe and calming. The only notable contraindication is for individuals with a severe ear infection or significant pain in the ear canal, as the vibrations could cause discomfort.
Intermediate Practices
4. Ujjayi Pranayama (Victorious Breath)
Ujjayi, or “victorious breath,” is characterized by a soft, whispering sound created by a gentle constriction at the back of the throat. It’s often used during yoga asana practice to maintain a steady rhythm and focus.
How to Practice:
- Sit or stand with a straight spine.
- Inhale and exhale through your nose, keeping your mouth closed.
- Gently constrict the back of your throat as if you are fogging up a mirror, but with your mouth closed.
- This creates a soft, audible “hissing” sound.
- Practice for 5 minutes (Remember to do it slowly and deep)
Benefits:
- Enhances focus during asana practice
- Builds internal heat
- Improves concentration
- Prepares mind for meditation
Ujjayi is considered a safe and foundational practice. However, individuals with high blood pressure should avoid forceful or long breath holds (kumbhaka) during this practice, as it can increase blood pressure. The breath should remain soft and effortless.
5. Chandra Bhedana Pranayama (Left Nostril Breathing)
Chandra Bhedan is a cooling and calming practice, as “Chandra” means moon. It is thought to activate the ida nadi, or lunar energy channel, which is associated with relaxation and the parasympathetic nervous system.
How to Practice:
- Left hand in chin mudra and right hand innasikagra mudra.
- Index andmidel in between the eyebrows and thumb on th eright nostril and ring finger and little finger on the left nostril.
- Exhale from the left and then begin th epranamaya by breathing in from the left and exhaling from the right.
- Repeat this cycle, always inhaling through the left and exhaling through the right.
Benefits:
- Activates the parasympathetic nervous system, helping to reduce stress and anxiety.
- Known as a “cooling” breath, it’s beneficial for lowering body heat, especially during warm weather or fevers.
- The practice has a tranquilizing effect on the brain, helping to manage agitation and promote mental clarity.
- Its calming properties make it an effective technique for those who struggle with insomnia, helping to improve sleep quality.
- Regulates Blood Pressure.
- This technique is believed to activate the Ida Nadi, or lunar energy channel, which brings a sense of balance and peace.
This technique is designed to be cooling and calming. It should be avoided by individuals who are already experiencing low blood pressure or lethargy, as it could further decrease their energy levels.
