Bhramari: the humming bee breath

Bhramari is named for bhramar, the black Indian bee, because that is what it sounds like: a low, even hum on every out-breath. It is taught to beginners because it is almost impossible to do badly, and it is kept by advanced practitioners because it works.

It is also the practice I would pick if someone told me I could only teach one breathing technique for the rest of my life.

How to do it

1. Sit comfortably, spine upright but not braced. A chair is fine. Our guide to sitting for meditation covers the options.
2. Close your eyes and let the face soften — jaw, tongue, the space between the eyebrows.
3. Close the ears gently. Press the small flap of cartilage at the front of each ear inwards with the index fingers. Gently: this is a light contact, not a plug.
4. Breathe in through the nose, unhurried, without filling to the brim.
5. Hum out — mouth closed, teeth slightly apart, a smooth low mmmmm that lasts as long as it comfortably can. Feel it in the skull, not the throat.
6. Pause, breathe in again, and repeat. Five rounds to begin, building to ten or more.
7. Sit still afterwards for a minute with the hands down and the eyes closed. The quiet after the last hum is the part people remember.

The pitch should be low and steady — a bee, not a mosquito. If the sound wobbles or runs out abruptly, you took in too much air at the start. Let the in-breath be about two-thirds of what you could take.

What to do with the arms

Holding the elbows out at shoulder height, as the classical description has it, becomes tiring within a few minutes and the tension defeats the purpose. Two alternatives we use:

• Let the elbows drop so the upper arms rest close to the ribs. The ears are still closed and nothing aches.
• Leave the ears open altogether and rest the hands on the thighs. The practice still works. Closing the ears intensifies the internal sound; it is not the active ingredient.

Some teachers add shanmukhi mudra, closing eyes, ears and the upper lip with the fingers of both hands. It is a lovely thing to do occasionally and unnecessary for daily practice.

Why the humming does something

Two mechanisms are reasonably well established, and it is worth separating them from the claims that are not.

The exhalation is long. Any breathing practice with a slow out-breath shifts the balance of the autonomic nervous system towards the parasympathetic side — the one that slows the heart and lowers blood pressure. Bhramari does this reliably because humming forces a slow, controlled exhalation. You could not hum fast if you tried.

Humming raises nasal nitric oxide. This is the genuinely interesting one. The sinuses produce nitric oxide continuously, and humming increases the amount released into the nasal airway dramatically — measurements of roughly fifteenfold are widely reported. Nitric oxide widens blood vessels and has antimicrobial properties in the airway.

What that does not establish is any of the larger claims made for bhramari in places that sell courses. A rise in nasal nitric oxide is a measurable local effect. It is not a cure for anything.

What the research actually shows

Bhramari has been studied more than most pranayama, partly because it is easy to standardise: everyone hums much the same way.

• Heart rate and blood pressure drop measurably after sessions as short as five to ten minutes, in a number of controlled trials.
• Anxiety scores fall on standard questionnaires, and heart rate variability shifts towards parasympathetic dominance during practice.
• Sleep quality improves in several studies, which matches what students report.
• Tinnitus symptoms improve in some small trials — of interest because tinnitus is otherwise so hard to treat.

A 2024 review in the Indian Journal of Physiology and Pharmacology pulled these together and found consistent reductions in stress, anxiety, depression scores and blood pressure among people practising regularly.

The honest caveats: these studies are mostly small, often unblinded — you cannot blind someone to whether they are humming — and frequently run in India by researchers sympathetic to yoga. The direction of the findings is consistent and the effects are modest. Treat it as a good, free, low-risk thing to do, not as medicine.

When it helps most

Four situations where I give it specifically:

• Before sleep. Ten rounds sitting on the edge of the bed. It is the most common thing I teach visitors who arrive jet-lagged and wired, alongside the evening sequence.
• Before meditation. It quietens the internal chatter more efficiently than trying to quieten it directly, which is why it is traditionally placed at the start of sitting practice.
• In an anxious moment. Three or four rounds, ears open, anywhere you can hum without attracting comment. Yoga for anxiety puts this in context.
• When the throat is tight from a day of talking. The vibration is pleasant and the long exhalation settles the voice.

Morning or evening both work. Unlike kapalabhati, which is stimulating and belongs in the morning, bhramari is calming and belongs wherever you need calming.

The usual mistakes

• Pressing the ears hard. A firm push into the ear canal is uncomfortable and unnecessary. Light contact on the cartilage.
• Humming too high. A high pitch tightens the throat. Find the lowest note you can hold steadily.
• Overfilling the lungs, then running out of air halfway and gasping.
• Straining the last second of the hum. Stop while there is still air left. Pranayama that ends in a gasp is being done for the wrong reason.
• Too many rounds at once. Some people feel light-headed after fifteen or twenty. Build slowly.

Who should be careful

This is one of the safest practices in yoga, and the list is short:

• Active ear infection — leave the ears alone entirely, or skip the practice until it clears.
• Recent ear surgery, or a perforated eardrum — practise with the ears open, and check with your doctor.
• Pregnancy — fine, and often welcome. Keep it gentle and skip any breath retention.
• Epilepsy — most breathing practice is fine, but discuss any new pranayama with your neurologist first.

Do not add breath retention to bhramari unless a teacher who knows you has said to. The practice does not need it.

Learning it properly

Bhramari is one of the few practices that transfers well through writing, because there is so little to go wrong. If you want the correction anyway — the pitch, the arms, the length of the in-breath — it is in every daily class here, and the teacher training spends a morning on it. A private session will sort out the details in twenty minutes.

Common questions

How many rounds of bhramari should I do?

Five to begin with, building to ten or more. Twice a day is plenty. Some people feel light-headed beyond fifteen rounds in one sitting, so build up gradually rather than starting long.

What is the best time to practise bhramari?

Whenever you want to settle: before sleep, before meditation, or in an anxious moment. Unlike kapalabhati, which is stimulating and suits the morning, bhramari is calming and has no wrong time of day.

Does bhramari help you sleep?

Several studies report improved sleep quality with regular practice, and it is the technique students most often tell me made a difference. Ten rounds sitting on the edge of the bed is the usual prescription.

Do I have to close my ears?

No. Closing the ears makes the internal sound louder and more absorbing, but the practice works with the hands resting on the thighs. If your arms tire at shoulder height, let the elbows drop — the tension defeats the purpose.

Is bhramari safe with tinnitus?

Some small trials report an improvement in tinnitus symptoms, so it is often suggested. If you have an active ear infection, recent ear surgery or a perforated eardrum, practise with the ears open and speak to your doctor first.
