What is Conscious Connected Breathwork?

One continuous breath, a known shift in blood chemistry, and an honest account of where the practice came from and who it suits.

Key takeaways

  • Conscious Connected Breathwork is a breathing practice in which each inhale flows into the exhale with no pause, sustained for most of an hour.
  • Breathing more than the body needs lowers carbon dioxide in the blood, and most of what people feel, from tingling to altered states, follows from that one change.
  • It grew out of Rebirthing, which Leonard Orr developed in the 1970s, and it is a close relative of Holotropic Breathwork. One study found the two produce very similar effects.
  • It isn't suitable for everyone, and the way a session is paced and held by a trained breathwork facilitator shapes the experience as much as the technique does.

Maybe you’ve seen the phrase on a session listing, or heard about a session from a friend. Someone cried. Someone’s hands cramped. Someone called it the strangest hour of their year. None of that tells you what actually happens when you lie down and start breathing.

Most of what’s written about Conscious Connected Breathwork is either an event blurb or a list of large promises, and neither explains the breath itself.

So here it is in order: the technique, the chemistry behind what people feel, what a session is like, where the practice came from, how it compares with Holotropic Breathwork, and who should sit it out.

What is Conscious Connected Breathwork?

Conscious Connected Breathwork is a breathing practice in which each inhale flows straight into the exhale, with no pause, for most of an hour. The breath is fuller than the body needs at rest, which shifts your blood chemistry and produces most of what people feel.

Researchers place it in a family they call circular breathwork: techniques in which the inhale and exhale are actively joined in a continuous cycle (opens in new tab). It is one style within the wider practice of breathwork.

What sets it apart:

  • Continuous. There’s no pause at the top or the bottom of the breath. One breath rolls into the next.
  • Fuller than usual. You breathe more, and often faster, than you would sitting still.
  • Sustained. In my sessions, the active breathing lasts 45 to 50 minutes.
  • Held. You usually lie down, with music, guided by a facilitator who watches and adjusts the pace. In person, a trained facilitator can also work actively with you, using hands-on adjustments drawn from bodywork, guided by where the breath seems to be moving or held.
  • Breathed through a chosen channel. Schools differ. Some breathe in and out through the mouth. I guide people to breathe in through the nose and out through the mouth, which is the gentler of the two.

You’ll also see it called circular breathing or connected breathing. The technique is the same.

How does Conscious Connected Breathwork work?

Breathing more than your body needs clears carbon dioxide from your blood faster than you produce it. With less carbon dioxide, the blood becomes slightly more alkaline. That makes nerves more excitable and narrows blood vessels in the brain. Tingling, cramping, and altered states follow from there.

Step by step:

  1. Carbon dioxide falls. Breathing beyond what your metabolism needs is, technically, hyperventilation. Whether a session feels anything like the hyperventilation of a panic attack depends largely on how it’s guided: the pace, the breath channel, and a facilitator who can slow you down. In a session it’s deliberate, and you can slow it at any point.
  2. The blood becomes more alkaline. Carbon dioxide is the main thing keeping blood pH steady. When it drops, pH rises. Clinicians call this respiratory alkalosis.
  3. Nerves get jumpy. At a higher pH, more calcium binds to proteins in the blood, leaving less of it free around your nerves. The result is pins and needles around the mouth and in the hands and feet, cramps, and in stronger cases, hands that curl inwards (opens in new tab). That curling is called tetany.
  4. Blood flow to the brain eases off. Low carbon dioxide narrows the blood vessels in the brain (opens in new tab), reducing blood flow there. In a 2025 imaging study, blood flow to the brain fell by about 30 to 40% (opens in new tab) during a session. This is one likely reason the session can feel unlike ordinary waking life.

When you read it this way, it might sound alarming, but in a guided practice it’s a controlled shift, and it eases soon after the breath slows.

  1. OneFaster, deeper breathing
  2. TwoCarbon dioxide falls
  3. ThreeBlood becomes more alkaline
  4. FourNerves fire more easily: tingling, then tetany
The whole sensation sequence, from one change. In sequence: breathing faster and deeper than the body needs lowers blood carbon dioxide; lower carbon dioxide raises blood pH; higher pH leaves less free calcium available to nerve tissue; and more excitable nerves produce tingling, and then tetany.

What the research does and doesn’t show:

What we know
Established The chemistry above, and the sensations it produces. These are standard respiratory physiology.
Observed in studies In a 2025 study of 61 experienced practitioners (opens in new tab), the further a person’s carbon dioxide fell during a session, the deeper their altered state tended to be. In a small study of 20 adults (opens in new tab), one session changed resting brain activity and lifted mood. Both studies are small and early.
Not yet known Why the experience so often brings emotion with it, and why that emotion can feel different from the everyday kind.

That last row matters. The physiology is well understood. The emotional side is consistently reported and poorly explained, and an honest account keeps the two apart.

What does a Conscious Connected Breathwork session feel like?

Every breathwork session is different. The sensations might be fairly predictable, but how strongly you feel them varies a lot from person to person, and from one session to the next. Common ones:

  • Tingling in the hands, face, and feet, often within the first few minutes
  • Tetany: hands curling, forearms or jaw tightening. It looks dramatic, it’s generally harmless, and it eases when the breath softens.
  • Changes in temperature and a sense of heaviness or buzzing
  • Emotion: tears, laughter, or a sense of peace that surprises you
  • Stillness in the rest phase, which many people find the most settled part of the session

Tingling and tetany are so expected that even clinical guidance on a few minutes of hyperventilation lists them as ordinary effects (opens in new tab).

A session with me runs like this:

Phase What happens
Arrival a conversation about how you are, and a simple intention
Active breathing 45 to 50 minutes, guided, with music
Relaxation 15 to 20 minutes of normal breathing, lying still
Debrief talking through what came up, and what to do with it afterwards

A lot of people go in expecting a breakthrough and come out wondering whether they did it wrong. “Am I just not ready?” is a common question. A quiet session isn’t a failed one. Expectation shapes the experience more than most people realise, and plenty of sessions are simply an hour of noticing your body in more detail than usual.

For anyone who tends to narrate their feelings while they’re having them, one thing stands out: the sensation arrives before the story does. Your hands are tingling before you’ve decided what that means. For people who live mostly in their heads, like me, that reversal is often the most interesting part.

Where does Conscious Connected Breathwork come from?

Conscious Connected Breathwork grew out of Rebirthing, a practice Leonard Orr developed and taught in the United States in the 1970s. The breath has outlasted the theory Orr built around it.

Orr believed the connected breath let people re-live their own birth and release what had happened there. The memory research doesn’t support that. On average, adults’ earliest memories go back to about two and a half years (opens in new tab), well after birth.

The breath itself kept travelling. Researchers now group Rebirthing, Conscious Connected Breathwork, Holotropic Breathwork, and Transformational Breath together as circular breathwork (opens in new tab), and the same connected pattern runs through later methods such as Vivation. Evolution of Breath, where I trained, combines Conscious Connected Breathwork with music, toning (sustained vocal sounds), fascia exercises, bodywork, and hands-on adjustments, to keep a session safe and support overall regulation.

I work with the breath and leave the birth-memory claims in the history books.

Conscious Connected Breathwork vs Holotropic Breathwork

The breath is much the same in both. Holotropic Breathwork runs longer, uses evocative music and bodywork, and pairs each breather with a sitter. In one study, the two styles produced very similar physical and experiential effects.

Conscious Connected Breathwork Holotropic Breathwork Rebirthing (original)
Origin grew out of Rebirthing; taught by many schools Stanislav Grof, a psychiatrist, 1970s Leonard Orr, 1970s
The breath continuous, no pause faster and deeper, continuous continuous, no pause
Typical length about 1 to 1.5 hours about 2.5 to 3 hours varied
Setting one-to-one or group, guided group, with breathers and sitters in pairs one-to-one with a “rebirther”
Stated aim varies by school non-ordinary states and self-exploration re-living birth

In the 2025 study (opens in new tab), Holotropic Breathwork sessions lasted around two and a half to three hours, with participants taking turns as breather and sitter. Conscious Connected Breathwork sessions lasted around an hour and a half, with two facilitators. Both produced similar falls in carbon dioxide and similar experiences. Grof developed Holotropic Breathwork as a prolonged, voluntary hyperventilation procedure (opens in new tab), so the overlap is no surprise.

In practice the differences are format, length, and framing.

Why the same breath can feel gentle or overwhelming

The technique is only part of the story. How long you breathe, which way the air goes in and out, how the session is paced, and who is guiding can change the experience, often more than the style’s name does.

What changes it:

  • Length of active breathing. Longer, unbroken breathing lowers carbon dioxide further and for longer.
  • Breath channel. Breathing in and out through the mouth moves more air and tends to be more intense. Breathing in through the nose adds a little resistance and slows things down. In exercise studies, nose breathing lowered overall ventilation and kept carbon dioxide higher (opens in new tab) than mouth breathing.
  • Pacing and rest. A proper relaxation phase gives the body time to settle back before you get up.
  • Facilitation and screening. A health form beforehand, and a trained facilitator in the room who knows when to slow you down.
  • Your state that day. Sleep, stress, and whatever is on your mind all play a part.

My own choices are deliberate. I guide people to breathe in through the nose and out through the mouth, because it’s more regulating than breathing through the mouth alone. It’s also how I was trained at Evolution of Breath. The active breathing lasts 45 to 50 minutes, followed by 15 to 20 minutes of rest and a debrief, and I read a health form before every session.

The aim is to stay within what your system can take in, sometimes called the window of tolerance, and to build comfort in the body over time. Big releases sometimes happen. They’re never the measure of a good session.

Is Conscious Connected Breathwork safe?

For most healthy adults, screened beforehand and guided by a trained facilitator, Conscious Connected Breathwork is generally well tolerated. It isn’t suitable for everyone, and calling a session “gentle” doesn’t make it gentle for every nervous system.

Context helps here. UK clinical guidance treats even three to five minutes of hyperventilation during a hospital EEG as reasonably safe, with a small risk of seizures and of heart, breathing, and circulation events (opens in new tab). A session lasts far longer than that, which is why screening isn’t optional.

Don't do Conscious Connected Breathwork, or speak to your doctor first, if you have or have had

  • pregnancy
  • heart disease, angina, a recent heart attack, or uncontrolled high blood pressure
  • a stroke, aneurysm, or other cerebrovascular disease
  • epilepsy or any seizure disorder
  • significant lung disease, severe or poorly controlled asthma, or breathlessness at rest
  • sickle cell disease or trait
  • glaucoma or retinal detachment
  • recent surgery
  • psychosis, schizophrenia, or bipolar disorder
  • panic disorder, which a long, activating session can aggravate

Breathwork research uses similar exclusions (opens in new tab). And never practise it in water, while driving, or anywhere fainting would be dangerous.

Where this leaves you

You now know what Conscious Connected Breathwork is: one continuous breath, a predictable change in blood chemistry, and a set of sensations that follow from it. What’s left is a question no article can answer for you, which is whether you’d like to feel it, and how.

If you would, here’s what a session with me looks like.

Frequently Asked Questions About Conscious Connected Breathwork

How long is a Conscious Connected Breathwork session?

Usually 90 minutes to 2 hours in total. A session with me has 45 to 50 minutes of active breathing, then 15 to 20 minutes of rest and a debrief. Elsewhere, formats range from short guided rounds to the three-hour sessions common in Holotropic Breathwork.

Can you do Conscious Connected Breathwork at home on your own?

Short, gentle breathing practices are fine alone. A full session of 45 minutes or more is better done with a trained facilitator, especially the first few times. Long over-breathing can bring on strong sensations or emotion, and it helps to have someone there who knows when to slow you down.

Why do my hands cramp during breathwork?

It's tetany: lower carbon dioxide reduces the free calcium around your nerves, and the muscles in your hands tighten. In a supervised session it's generally harmless and passes quickly. Softening the exhale and letting it fall out on its own usually eases it within a minute or two.

What if nothing happens in a session?

That's common, and it doesn't mean you did it wrong. Expecting a breakthrough tends to make you watch for one. Many sessions are quiet, and noticing your body in more detail than usual is already the practice working.

Should I breathe through my nose or my mouth?

Schools differ. Breathing in and out through the mouth is more intense. Breathing in through the nose and out through the mouth is more regulating, and it's what I use in my sessions. If you're new to the practice, the gentler pattern is a sensible place to start.

Is it normal to cry during breathwork?

Yes. Tears are one of the most common responses, and so is laughter. Neither is required, and nobody should ask you to produce either. If emotion comes, you let it move. If it doesn't, the session is still doing its work.
