Pranayama

Bhastrika (Bellows Breath)

Forceful breaths in and out, about one a second. It warms you up and wakes you fast.

Also called: Bellows breath, Bhastrika pranayama, Bhastrika breathing

Bhastrika is a yogic breathing technique in which you breathe in and out through the nose with equal, forceful strokes, like a blacksmith's bellows. Unlike Kapalbhati, where only the exhale is pushed, both directions work here.

A few rounds leave you warm and wide awake within minutes. Do it in the morning or as a midday lift, and keep it away from bedtime.

Pattern: Forceful in, forceful out, about 1 breath per second
Session: 3 sets of 20 breaths with short rests, about 2.5 minutes
Good for: Energy and warmth; waking up
Level: Intermediate
Origin: Hatha yoga (Hatha Yoga Pradipika)
Needs: iPhone or Apple Watch

How to do it

Wait two to three hours after a meal. Sit tall with your hands on your knees. Breathe through your nose only.
Take one or two normal breaths, then a moderate breath in.
Breathe in forcefully, fast enough to hear it. Let your chest and belly expand.
Right away, breathe out just as forcefully, pulling your belly in.
Keep both strokes equal in force and speed, about one breath per second, like a steady pump.
Do 10 to 20 breaths for a set. Then rest for about 45 seconds with easy breathing.
Do 2 or 3 sets. Add breaths over days, once the rhythm stays even.
Finish with slow, natural breathing. Notice the warmth before you move on.

Benefits

Energy in a couple of minutes
Fast, forceful breathing raises your heart rate and tips your nervous system toward its alert side^[1]. You feel warm and switched on.
Better breathing in four weeks
In a trial with 110 young adults, four weeks of Bhastrika improved blood oxygen saturation and peak expiratory flow^[2].
A lighter mood
In a small trial, four weeks of a Bhastrika-based practice lowered anxiety and negative mood in healthy young adults^[3].
Warm from the inside
In yoga tradition, Bhastrika is the warming breath, said to stoke the digestive fire^[4]. You feel the heat build within a set.

What the research says

Two small randomized trials have tested Bhastrika over four weeks. In 110 healthy adults aged 18 to 25, practice improved blood oxygen saturation, breathing rate and peak expiratory flow, and lowered heart rate and blood pressure slightly, while a no-practice control group did not change^[2]. In 30 healthy young adults, it lowered anxiety and negative mood, with matching changes in emotion-related brain areas on scans^[3]. That trial's version paired fast, exhale-led breathing with a slow right-nostril inhale and a breath hold, so it differs from the plain bellows breath^[3].

Pace changes the effect. Done slowly, at six breaths a minute for five minutes, Bhastrika lowered blood pressure in 39 volunteers; a separate group given a drug that blocks the calming (parasympathetic) nerves showed no drop^[5]. Done fast, as most classes teach it, it raised heart rate and shifted heart rate variability toward the stimulating side in 20 regular yoga practitioners^[1].

All of these studies are small and short, and none included people with the conditions on the safety list below. The traditional benefits, from clearing phlegm to awakening kundalini, come from the Hatha Yoga Pradipika, not from trials^[4].

Bhastrika vs Kapalbhati and Breath of Fire

Both Bhastrika and Kapalbhati are rapid nasal breaths from Hatha yoga, and both wake you up. In Kapalbhati only the exhale is forceful and the inhale is a passive rebound. In Bhastrika you drive the inhale and the exhale with equal force, so it is deeper, louder and more heating.

Some classes call Bhastrika "breath of fire". Kundalini Yoga's Breath of Fire is a different practice: the inhale and exhale take equal time with no pause, only the exhale is active, and it runs at about 2 to 3 breaths per second. Its teachers say plainly that it is not Bellows Breath^[6].

The classical closing hold

In the Hatha Yoga Pradipika, a round of Bhastrika ends with a full breath in through the right nostril, a held breath, and a breath out through the left^[4]. Some modern classes keep a short hold at the end of each round. Others simply pause and notice how the body feels. Spoon leaves the hold out and gives you an easy rest between sets.

Tips

Keep the inhale as strong as the exhale. If it turns soft and passive, you have drifted into Kapalbhati.
Let your diaphragm and lower ribs drive each stroke. A hiss in the throat means the breath is too shallow.
Keep your face, jaw and shoulders soft. A hand on your belly helps.
Start at a pace you can hold for the whole set. Speed comes over days.
If you feel dizzy, stop, lie down and let your breath settle.

Safety

Skip it if you are pregnant or on your period (a traditional yoga caution), or if you have a hernia, recent abdominal or eye surgery, glaucoma or a detached retina.
Ask your doctor first if you have high or low blood pressure, heart disease, epilepsy, vertigo, panic attacks, or a kidney, spleen or pancreas condition.
Teachers also advise skipping it when you have a fever, a badly blocked nose or an asthma flare.
Always practice sitting, on the floor or a chair. Never in or near water, never while driving, never standing up.
Do not add long breath holds after your sets, and do not go straight into a breath-hold exercise. Fast breathing followed by a hold can make you faint.
Stop at once for chest pain, sharp belly pain, changes in your vision, or more than mild lightheadedness. Mild tingling is a signal to slow down.

Bhastrika in Spoon

Spoon guides Bhastrika on iPhone and Apple Watch in counted sets. The default is 3 sets of 20 breaths with 45 seconds of rest between them, about 2.5 minutes in all. The pace stays at one full breath per second: half a second in, half a second out.

Breath sounds mark each inhale and exhale, and your Watch taps your wrist on every breath and as each rest begins. With the voice guide on (Guided session: Voice), your iPhone says "Stay with the rhythm" as each set begins. Spoon guides the bellows breathing and the rests, without the classical closing hold.

Default: 3 sets of 20 breaths, 45 seconds of rest between sets.
Set 10 to 30 breaths per set, 1 to 5 sets, and 15 to 90 seconds of rest.
A tap on your wrist for every inhale and exhale, and as each rest begins.
On your Watch, tap the circle during a rest to skip it.
With an Apple Watch: live heart rate, an optional heart rate goal, and your breath and heart rate on one chart after the session.
Save your settings or add Bhastrika to a playlist.

Questions

What is the difference between Bhastrika and Kapalbhati?

In Bhastrika you push air in and out with equal force, like a bellows. In Kapalbhati only the exhale is forceful and the inhale happens by itself. Bhastrika is deeper, louder and more heating. Both are stimulating breaths for the morning or a midday lift, never for bedtime.

Is Bhastrika the same as Breath of Fire?

No, although many classes mix up the names. Breath of Fire comes from Kundalini Yoga: the inhale and exhale take equal time, only the exhale is active, and the pace is about two to three breaths per second. Bhastrika comes from Hatha yoga, uses force in both directions, and is slower and deeper.

How many rounds of Bhastrika should you do?

Start with 2 or 3 sets of 10 to 20 breaths, with about 45 seconds of easy breathing between sets. That takes 1 to 3 minutes. Add breaths over days, once your rhythm stays even and you feel no dizziness.

When should you do Bhastrika?

In the morning, on a cold day, or whenever you need energy, always on an empty stomach. It raises your heart rate and leaves you alert, so keep it away from bedtime.

Is Bhastrika safe?

For healthy adults who practice seated, in short sets, it is. Skip it if you are pregnant or have a hernia or recent abdominal or eye surgery. Ask a doctor first if you have high or low blood pressure, heart disease, epilepsy or vertigo. Never do it in or near water or while driving, and stop if you feel more than mild dizziness.

Does Bhastrika lower blood pressure?

A slow version did, at six breaths a minute, in one five-minute session. In a four-week trial with young adults, heart rate and blood pressure dropped only slightly. The fast version raises your heart rate while you do it, so if you have high blood pressure, ask your doctor before you try it.
