Classical source documentation

Charaka Samhita, Sutrasthana 7 documents specific Pranayama (breathing practices) in the context of Manas (mental) conditions. Ashtanga Hridayam, Sutrasthana 2 documents Pranayama in the Dinacharya chapter. Yoga Sutras, Hatha Yoga Pradipika, and Gheranda Samhita provide the Yoga-tradition documentation of specific techniques. The classical Ayurvedic prescription uses specific Pranayama types as clinical interventions for Dosha imbalances.

Charaka Samhita, Sutrasthana 7.52
Pranayama manasa rogam nirodhayati / Mano hi prana samyukta -- Pranayama controls mental disease. Mind and Prana are connected -- where Prana goes, mind follows. By regulating Prana through breath control, the Manas is directly regulated.

Pranayama by Dosha

Vata -- Nadi Shodhana (Alternate Nostril Breathing)

The primary classical Pranayama for Vata: Nadi Shodhana (alternate nostril breathing -- Surya and Chandra Bhedana combined). Charaka Samhita documents the breath as the primary vehicle of Vata, and the regulation of nostril alternation as directly regulating the Ida and Pingala Nadi (the classical energy channels corresponding to the left and right nostrils). The balancing, calming quality of Nadi Shodhana counters Vata's erratic, ungrounded quality. Ratio: equal inhale and exhale, with progressive lengthening. Avoid: Kapalabhati and Bhastrika (too activating for aggravated Vata).

Pitta -- Sheetali and Sheetkari (Cooling Breath)

The primary Pranayama for Pitta: Sheetali (curling the tongue lengthwise and inhaling through it -- producing a cooling stream of air) and Sheetkari (teeth slightly parted, inhaling through the gap). Ashtanga Hridayam documents cooling breath practices for Pitta-type Daha (burning sensation), Trishna (thirst), and Pitta mental conditions (anger, irritability). The direct cooling of inspired air is documented as reducing Bhrajaka Pitta (skin Pitta) and Sadhaka Pitta (mental Pitta) simultaneously. Contraindications: Sheetali should not be practiced in cold or dry conditions -- it increases Vata and Kapha in excess.

Kapha -- Bhastrika and Kapalabhati (Bellows and Skull-Shining Breath)

The primary Pranayama for Kapha: Bhastrika (bellows breath -- forceful, rapid inhalation and exhalation through the nose) and Kapalabhati (rapid, forceful exhalation with passive inhalation -- skull-shining breath). Both are documented in Hatha Yoga texts for Kapha and Meda (fat) conditions. Charaka Samhita's documentation of Deepana (Agni-kindling) practices aligns with Bhastrika and Kapalabhati -- both produce internal heat, clear the respiratory channels of Kapha, and stimulate Agni. Contraindications: both are absolutely contraindicated in pregnancy, hypertension, epilepsy, acute respiratory infections, and active Pitta aggravation.

Pranayama for specific conditions

Anidra (insomnia -- Vata): Nadi Shodhana with extended exhalation (1:2 inhale:exhale ratio); Bhramari (humming bee breath -- the vibration directly calms Vata in the nervous system and Pranavaha Srotas in the head). Evening practice only.

Anxiety (Chittodvega -- Vata-Rajas): Nadi Shodhana; Bhramari; extended exhale Pranayama (longer exhalation than inhalation directly activates the parasympathetic nervous system -- the modern equivalent of the classical Vata-calming mechanism).

Respiratory conditions (Kasa, Shwasa -- Kapha): Kapalabhati for Kaphaja; Ujjayi (victorious breath -- gentle constriction of the glottis producing ocean-sound breath) for all Kasa and Shwasa types as it opens the bronchial channels with minimal Dosha aggravation.

Digestive conditions (Mandagni -- Kapha-type weak Agni): Agni Sara (rapid uddiyana-bandha pumping) and Bhastrika are specifically documented for kindling digestive Agni. Classical texts document Pranayama as a component of Agni management alongside dietary intervention.

Contraindications -- not universal
All Pranayama practices have contraindications. Absolute contraindications for forceful practices (Bhastrika, Kapalabhati, Agni Sara): pregnancy (documented risk of placental stress); epilepsy (hyperventilation can trigger seizures); uncontrolled hypertension (intrathoracic pressure changes can spike blood pressure); recent surgery; and detached retina. All Pranayama should be learned from a qualified teacher before attempting extended independent practice.
