Bhramari, the “bee breath” or “humming breath”, is a calming pranayama described in the Hatha Yoga Pradipika 2.68 and in the Gheranda Samhita 5.73–77. The practice consists of a slow inhalation through both nostrils followed by an extended exhalation during which the practitioner produces a continuous humming sound at the back of the throat, similar to a female bee (bhramari). Typical practice runs 5 to 10 rounds and takes 5 to 8 minutes. The technique is one of the safest pranayamas, suitable for almost any age and condition, and has been studied for measurable effects on heart rate variability and blood pressure.
Source and meaning
The Sanskrit bhramari means “bee”, specifically the large black female bee whose humming sound the practice imitates. The Hatha Yoga Pradipika 2.68 gives the verse: “Performing inhalation rapidly, making the sound of a male bee, and exhalation slowly making the sound of a female bee, this yogic practice produces a state of bliss in the mind of the yogis.” The Gheranda Samhita 5.73–77 expands the description and places the practice in the eight kumbhakas. Both texts emphasise the sound of the female bee in the exhalation as the more important phase.
The basic technique
- Sit in Sukhasana, Padmasana or on a chair with the spine erect.
- Optionally close the ears with the thumbs (shanmukhi mudra), with the index fingers above the eyebrows, the middle fingers on the closed eyelids, the ring fingers on the sides of the nose, and the little fingers at the corners of the mouth. The simpler version just rests the hands on the knees.
- Close the eyes lightly. Take a steady inhalation through both nostrils.
- On the exhalation, produce a continuous humming sound at the back of the throat. The mouth stays closed; the sound resonates in the skull and the chest.
- The exhalation should be three to four times longer than the inhalation. Aim for an exhalation of 15 to 20 seconds once the technique is established.
- Five to ten rounds. Sit quietly for two minutes after the last round.
The pitch of the hum is whatever feels natural and sustainable; most practitioners settle on a mid-range pitch. The sound should be smooth, not strained. A common beginner cue: imagine the hum vibrating between the eyebrows and the centre of the skull.
Variations across traditions
- Hatha Yoga Pradipika version: male-bee sound on inhalation, female-bee sound on exhalation. This bilateral version is rarely taught in modern classes; most schools have dropped the inhalation hum.
- Gheranda Samhita version: a longer description including the closing of the ears and the sound visualised as resonating in the brahmarandhra (crown).
- Bihar School (modern): shanmukhi mudra used routinely; the hum on exhalation only, with attention at the third-eye centre.
- Iyengar lineage: hum on exhalation only, with attention to the resonance in the chest and skull cavities. Shanmukhi mudra optional.
- Art of Living variant: Bhramari is taught as part of the Sudarshan Kriya sequence with specific count and visualisation.
Documented effects
Bhramari is one of the better-studied breathing techniques because the humming sound has a measurable physiological signature. The findings:
- Documented increase in exhaled nitric oxide during the humming phase, by 10 to 15 times baseline in some studies. Nitric oxide has vasodilatory and antimicrobial effects in the sinuses.
- Activation of the parasympathetic nervous system during and after the practice, with measurable drops in heart rate and blood pressure.
- Reduction in subjective anxiety and improvement in sleep onset in small clinical studies, particularly in patients with mild to moderate hypertension or generalised anxiety.
- Reported improvement in tinnitus symptoms in some small studies, though the evidence here is preliminary.
The classical claim, that the practice produces a state of bliss and quiets the mental fluctuations described in Patanjali Yoga Sutras 1.2 (chitta vritti nirodha), is consistent with the modern findings on autonomic calming and parasympathetic activation.
When and how often to practise
Bhramari is one of the few pranayamas where evening practice is encouraged. The calming effect makes it useful before sleep, where Bhastrika and Kapalbhati are contraindicated. Standard practice slots:
- Morning: at the end of a longer pranayama sequence, after Kapalbhati and Nadi Shodhana, before sitting meditation.
- Before sleep: 5 to 10 rounds, to bring the heart rate down and quiet the mind.
- During stress: 3 to 5 rounds as a discrete tool to interrupt rising agitation. The technique works well as a real-time intervention.
For what it’s worth, Bhramari is the pranayama most worth recommending to someone who is sceptical of yoga generally. The technique is simple, the effects are immediate and palpable, and the time investment is small. A daily five-minute practice for two weeks usually convinces the practitioner that something is happening.
Common questions
Can children practise Bhramari?
Yes. Bhramari is one of the few pranayamas explicitly taught to children in school yoga programmes (the Vivekananda Kendra and the Patanjali Yogpeeth syllabi include it). Children from age six or seven can practise three to five rounds. The humming sound is fun for children and the calming effect is documented in small school-based studies.
Is the shanmukhi mudra essential?
No. The hand position deepens the inward focus by closing off external sound and visual input, but the breath and the hum are the essential elements. Many practitioners find the hand position tiring; the simpler version with hands on knees is fully acceptable. Some teachers introduce shanmukhi mudra only after several months of basic practice.
Are there any contraindications?
Active ear infection or severe sinusitis can make the practice uncomfortable; in those cases the hum should be light and the duration short. Pregnancy is not a contraindication; many prenatal yoga programmes include Bhramari. Severe hypertension and anxiety disorders are explicit indications rather than contraindications, although the practice should not replace medical treatment.
Why does the humming feel resonant in the head?
The hum produces a 100 to 200 Hz vibration that travels through the bones of the skull and the sinuses; the sensation is a real mechanical vibration, not a metaphor. The same physics explains the increased nitric oxide measurements: the vibration agitates the sinus cavity gas and increases nitric oxide flux from the sinus epithelium. The classical reading of this as a resonance in the brahmarandhra and the physical reading as bony conduction of low-frequency vibration describe the same event in different languages.
One limitation worth noting
The published studies on Bhramari are small and most run for weeks rather than years; long-term effects on chronic conditions like hypertension or anxiety are inferred rather than demonstrated. The classical claim of a state of bliss is best read as a description of the calm that follows the practice, not as a clinical cure for depression or other serious conditions. Used as one daily habit alongside other lifestyle measures, Bhramari is well-supported; used as a standalone treatment for a clinical condition, it is unlikely to be enough on its own.
