Breath Of Fire: What Kapalabhati Really Is, And Why It Comes Last

Breath of fire: the short answer

Breath of fire is a fast, pumping belly breath. In Iyengar yoga it is called kapalabhati (shining skull breath), and it is a strong pranayama (yoga breathing practice) that comes last, not first. You learn calm breathing lying down, then sitting, then small pauses, and only then the fast breath, with a teacher watching.

• What it is: a quick push of air out from the belly, with a soft, passive breath in.
• Where it sits: last in the order, after lying, sitting and pause practice.
• Calm first: steady slow breathing comes before any fast breathing.
• Who waits: high or low blood pressure, pregnancy, heart disease and more.
• What research shows: small trials show some lung and focus benefits.
• How to learn it: in a studio class or LIVE online, with a teacher.
• New students: 12 classes for $59.50 in Darwin or LIVE online.

What is breath of fire?

Breath of fire is the name many people give to a quick, rhythmic belly breath. The older yoga name is kapalabhati. It means shining skull, because the practice is said to leave the head feeling clear and bright.

Here is how it works. The air drops in without effort. Then you push it out with a short, sharp pull of the belly towards your spine. Out, in, out, in, a bit like a pump. The push out is active, and the breath in is passive (it happens by itself).

In Light on Pranayama, Mr BKS Iyengar called it a milder form of bhastrika (the bellows breath), and said it brings “a feeling of exhilaration”. Mr Iyengar was the twentieth-century teacher who collected and passed on traditional Indian yoga, and he pioneered the use of props. His style is sometimes called modern classical yoga, and it is the style Flametree teaches.

Is breath of fire the same as kapalabhati?

Mostly, yes. Both names mean fast belly breathing, and teachers each do it a little differently. At Flametree it is taught as Shining Skull Breath, one of five pranayama practices. The other four are staircase breath (Viloma), humming breath (Bhramari), alternate nostril breath (Nadi Sodhana) and ocean breath (Ujjayi). All five are classical techniques used for thousands of years. None of them was invented by Mr Iyengar. Each teacher shapes them a little in their own way.

The Flametree way is led by Geeta Iyengar’s practical approach. It is gentle, step by step, and it never rushes a student towards the strong breaths.

Why does breath of fire come last?

Think of learning to drive. You do not start on a motorway. You learn the controls in a quiet car park first.

Breath is the same. Fast breathing is a strong tool. It speeds the breath, wakes up the body and changes how you feel within seconds. To use a strong tool well, you first need a steady base: a soft, smooth, even breath that you can control.

That is why the Iyengar way says: calm first, strong last. Mr Iyengar was firm that fast breathing and long breath holds come last, once the lungs and nerves are ready, and with a teacher nearby.

Skipping ahead can leave people light-headed or tense in the neck. A calm breath helps you notice that early.

The safe order for learning breath of fire

The ladder below is the order we follow. Each step makes the next one safer.

1. Lying down. Slow, soft breaths on the floor, often with a folded blanket under the chest. The body is held, so you can feel the breath move.
2. Sitting, with a chair and belt. Sitting tall is harder than it looks. A chair, a belt or a prop helps lift the chest so the lungs have room.
3. Small pauses. A tiny moment of stillness after a breath in or out. It grows slowly, over months, and only as far as it stays quiet.
4. The fast breath. Kapalabhati comes here, in short rounds, with rests of normal breathing between them.

Most people want to jump to step four. Most of the benefit of step four, though, comes from having done steps one to three well.

Who should wait for breath of fire?

Some people should wait. The fast breath is lively, not relaxing, and it asks more of the body than slow breathing does.

In Light on Pranayama, Mr Iyengar lists people who should not do kapalabhati. Taken with the Flametree Breathworks ebook, the list is:

• People with high or low blood pressure
• People with eye or ear complaints
• People who get nosebleeds
• People who are pregnant
• People with heart disease or epilepsy
• People with a hernia (a bulge through the belly wall) or recent belly surgery
• People who get panic attacks

If any of these sound like you, you are very welcome to start with the calm breathing. That is where most of the benefit is anyway, and it is open to nearly everyone. You can tell your teacher so we can look after you. This is an invitation, not a rule.

Fast breathing also never belongs in or near water. It can switch off the urge to breathe.

What does the research say about breath of fire?

Modern research on fast yoga breathing is small but growing. Here is what two studies found, according to PubMed.

Lungs. In a 2015 trial, 91 healthy young adults were split into three groups: slow pranayama, fast pranayama (kapalabhati, bhastrika and kukkriya) and no practice. Teachers supervised the practice for 30 minutes a day, three days a week, for 12 weeks. The fast group improved three lung measures. The slow group improved two. The group that did nothing did not change. DOI: 10.4103/0973-6131.146051

Focus and the calm side of the nervous system. In a 2024 study, 20 young adults learned kapalabhati over seven days. Straight after, they got more answers right on a working memory task (holding information in mind). They were also slower to answer. Their heart rhythm showed a shift towards the parasympathetic system, the body’s calming side. DOI: 10.7759/cureus.61027

Both studies are small and used young, healthy people. Most yoga and breath research is small because it is underfunded, so the full picture is still being drawn. There is also much known from practice: teachers have long noticed that fast breathing wakes people up and clears the nose. Research has not yet tested much of that.

How does breath of fire feel when it is taught well?

It feels light and lively. The belly pulses, the shoulders stay soft and the face is quiet. After a short round you rest, and the breath settles back into a calm rhythm. When it is rushed, the neck tightens and the breath turns loud and ragged. That is the sign to go back a rung on the ladder.

How does Flametree teach breath of fire?

In class, with a teacher, and in order. Our teachers watch each student’s face, neck and belly, and adapt the practice to the person. Props are supplied. Nobody is rushed up the ladder.

In Darwin, you can learn pranayama in the studio. You can also join LIVE online classes from anywhere. Either way, you have a teacher who can see you and guide you.

Want to see how this fits with the rest of breathwork? Read our guide to the benefits of breathwork and our post on whether pranayama is safe. Looking for classes? See breathwork classes near me. For the calm, steady breath that comes first, read about Ujjayi, the ocean breath.

Bhastrika, the bellows breath, is the stronger cousin of kapalabhati. Read bhastrika pranayama to see why it waits even longer.

Learn the calm breaths first

Our free ebook, the Breathworks Original Toolkit, explains the five breaths and the safe order in plain words. It explains yoga. It does not teach it, because breath is best learned with a teacher.

Breath of fire questions

Is breath of fire the same as kapalabhati?

Mostly, yes. Both names describe fast, pumping belly breathing. Kapalabhati is the traditional name and means shining skull. Teachers do it a little differently, and Flametree teaches it as Shining Skull Breath.

Is breath of fire safe for beginners?

It comes last in the Iyengar order. You learn calm breathing lying down, then sitting, then small pauses, and then the fast breath with a teacher. Beginners begin at the start of the ladder, and that is where most of the benefit is.

Who should not do breath of fire?

Mr Iyengar lists people with high or low blood pressure, eye or ear complaints, or nosebleeds. Flametree also asks people who are pregnant, or who have heart disease, epilepsy, a hernia, recent belly surgery or panic attacks, to wait. You can tell your teacher, and we will look after you.

What does breath of fire do?

It is a lively, waking breath. A 2015 trial of 91 young adults found fast pranayama improved three lung measures, and a small 2024 study found better working memory scores right after kapalabhati. Teachers also report it clears the nose and wakes the body.

How long should you do breath of fire?

In class, rounds are short, with normal breathing between them. Your teacher sets the pace for you. Long, hard sessions are not the aim, and nobody should push through dizziness or tension.

Can I learn breath of fire from a video?

A video cannot see your face, neck or belly. Kapalabhati is best learned from a teacher, in the studio or in a LIVE online class where the teacher can watch you.
