Therapeutic Pranayama

Therapeutic pranayama is the use of traditional yogic breathing practices for a specific health purpose, such as easing stress, supporting steadier breathing, or complementing the care of high blood pressure. Pranayama is the yoga tradition's name for breath practices, and in a therapeutic setting a teacher chooses a small number of techniques, sets the pace and duration to suit the person, and builds up gradually.

Common techniques include slow, even breathing, alternate nostril breathing (nadi shodhana), humming breath (bhramari), and the extended exhale that many people find calming. Faster practices, such as kapalabhati, and breath holding (kumbhaka) are used more cautiously, and are often left out for people with heart, lung, or eye conditions or in pregnancy. Some people use humming breath (bhramari) for anxiety or tinnitus and kapalabhati for respiratory function, and practitioners say these may help, though research on them is limited. Sessions are usually taught by yoga therapists, and sometimes by physiotherapists, nurses, or doctors who have trained in breath work.

Research on pranayama is growing but still limited. Reviews of small trials report modest improvements in heart rate, blood pressure, stress symptoms, and some breathing outcomes, but many studies are small, short, and at high risk of bias, and techniques vary. Pranayama is generally low risk when practiced slowly, and it should complement, never replace, medical care for hypertension, asthma, COPD, anxiety, or any other condition.

Pranayama is far older than the therapeutic use of it. The word is usually translated as the extension or regulation of the breath, and breath practices appear in early Indian texts, including the Upanishads and the Bhagavad Gita, which refers to restraining the in- and out-breath. In the Yoga Sutras of Patanjali, pranayama is the fourth of the eight limbs of yoga, presented as a way of steadying the mind. Later hatha yoga texts, such as the Hatha Yoga Pradipika, usually dated to about the fifteenth century, describe techniques such as alternate nostril breathing, bellows-style breathing, and breath retention (kumbhaka) in detail.

Modern scientific interest began in the twentieth century. Swami Kuvalayananda started experimental studies of pranayama in India in 1924 and founded the Kaivalyadhama institute, where he measured effects such as carbon dioxide removal and oxygen use. From the late twentieth century, yoga therapists, physiotherapists, and integrative physicians in India and elsewhere began to adapt selected techniques for health goals, and controlled trials followed. The phrase therapeutic pranayama describes this applied use, not a single lineage, and there is no unified curriculum or governing body. Training is mostly through yoga therapy programs, and techniques, pacing, and standards vary widely between teachers. Some modern forms, such as ujjayi breath, are recent additions to yoga practice.
