Rebirth therapy (often called “rebirthing”) refers to two very different practices that share a name, which has caused significant confusion. The original version, developed in the 1970s by psychotherapist Leonard Orr, is a breathing technique. The other, far more dangerous version is a physical restraint-based regression therapy that simulates the birth process. Understanding the difference matters, because one is a fringe but generally low-risk breathwork practice, while the other has been banned in multiple U.S. states after causing a child’s death.
Two Therapies, One Name
Leonard Orr’s rebirthing is predominantly a breathing technique, typically lasting around 45 to 50 minutes per session. It draws loosely on psychoanalyst Otto Rank’s 1924 theory that the trauma of birth is the most deeply repressed portion of the mind, and that anxiety and other symptoms can be traced back to it. The breathwork version aims to release stored emotional tension through a specific pattern of continuous breathing.
The other practice, sometimes called “rebirthing attachment therapy,” is a type of regression therapy that physically simulates the birth process. In its most extreme forms, practitioners wrap a person (often a child) tightly in blankets or sheets and apply pressure, instructing them to push their way out as if being born. This version gained national attention in 2000 when 10-year-old Candace Newmaker died during a 70-minute session in Colorado. Her therapists were convicted of reckless child abuse resulting in death, and Colorado subsequently banned the practice. Several other states followed.
How Rebirthing Breathwork Works
The breathwork version of rebirthing uses a technique now broadly called “conscious connected breathing.” It has four core components: breathing without any pauses between the inhale and exhale, using diaphragmatic (belly) breathing with relaxed chest expansion, letting the exhale happen passively rather than forcing it, and breathing in and out through the same channel (either nose or mouth throughout).
In practice, this means you lie down and breathe continuously in a rhythmic loop. The inhale is active and intentional. The exhale is a release, not a push. There’s no holding of the breath at any point. A typical session runs 40 to 50 minutes, and a full course usually involves 10 to 20 sessions.
This style of breathing is essentially voluntary hyperventilation. It lowers carbon dioxide levels in the blood, shifts blood pH toward alkalinity, and increases sympathetic nervous system activation. Physically, people often report tingling in the hands and face, lightheadedness, muscle tightness (especially in the fingers), and emotional surges. Practitioners frame these sensations as part of the therapeutic process, interpreting them as evidence of emotional release.
What the Science Says About Breathwork
No rigorous clinical trials have tested rebirthing breathwork specifically. The broader evidence on breathwork for mental health is more encouraging but comes with caveats. A scoping review of breathwork interventions for clinically diagnosed anxiety disorders found that a range of breathing techniques produced significant improvements in anxiety symptoms. Slow diaphragmatic and controlled breathing methods showed the most consistent benefits, including reductions in panic attack frequency that held up at six-month follow-ups.
The picture gets murkier with hyperventilation-based techniques like rebirthing. The review noted that results around the role of hyperventilation in treating anxiety were contradictory. One study found that both hyperventilation and slow breathing reduced panic disorder severity. Another showed that carbon dioxide changes from altered breathing patterns didn’t reliably correspond to symptom improvement. A separate finding revealed that hyperventilation caused panic attacks in some patients, and that elevated CO2 levels were a more potent trigger for anxiety than hyperventilation alone.
In short, general breathwork practices show real promise for anxiety and stress. But the specific mechanism rebirthing uses, sustained hyperventilation over 45 minutes, has a thinner and more mixed evidence base. The physiological demands are real: one study measuring metabolic responses during a rebirthing session found that oxygen uptake, heart rate, and respiratory exchange ratios stayed elevated throughout the full 40 to 50 minutes, comparable to sustained light exercise.
Physical Risks of Extended Hyperventilation
Breathing rapidly and continuously for 45 minutes produces measurable changes in blood chemistry. Carbon dioxide drops, blood becomes more alkaline, and neuronal excitability increases. For most healthy adults, this produces uncomfortable but temporary symptoms: tingling, cramping, dizziness, and sometimes a sensation of emotional overwhelm. These effects reverse once normal breathing resumes.
The risks increase for people with certain health conditions. Sustained hyperventilation can alter blood flow to the brain, spike heart rate, and shift electrolyte balance. People with cardiovascular conditions, seizure disorders, respiratory illnesses, or a history of severe panic attacks face higher risks from this kind of prolonged breathing alteration. Pregnant individuals are also generally advised to avoid the practice.
Practitioner Standards and Regulation
Rebirthing breathwork is not a regulated medical practice. The International Breathwork Foundation, the largest professional network for breathwork practitioners, requires members to follow a code of conduct but does not check certifications, verify training, or supervise standards. Membership is self-nominated and is not an endorsement of a practitioner’s qualifications. The organization partners with the Global Professional Breathwork Alliance (GPBA) for voluntary accreditation, but many practitioners opt out.
If you’re considering working with a rebirthing breathwork practitioner, look for the GPBA Certified Practitioner designation. Ask about their training background, how many sessions they’ve facilitated, and how they screen for health conditions that might make the practice unsafe. The lack of formal regulation means the quality and safety of sessions varies widely depending on who is leading them.
The Restraint-Based Version Is Banned
The physical rebirthing technique, where a person is wrapped, compressed, and told to fight their way out, is a fundamentally different practice from the breathwork. It was used primarily on adopted children with attachment disorders, based on the idea that re-enacting birth would create a new emotional bond with adoptive parents. No credible evidence supports this theory, and the practice carries extreme physical danger, particularly for children.
After Candace Newmaker’s death, Colorado passed “Candace’s Law” in 2001, banning the use of rebirthing therapy involving restraint, compression, or restriction of breathing. Other states enacted similar restrictions. The American Professional Society on the Abuse of Children and multiple psychological organizations have condemned the practice. If anyone offers a therapy that involves physical restraint and calls it “rebirthing,” that is not the same as breathwork, and it is illegal in several jurisdictions.
