What Is Breathwork? Definitions, Types and How the Term Is Used

A word with no single meaning

"Breathwork" has no single agreed definition. In research it is often used for any deliberate control of the breath. One 2023 meta-analysis of randomized trials defines it that way: "Deliberate control of the breath (breathwork)". [1] A 2025 narrative review similarly describes it as deliberately altering the way one breathes. [2] In wellness settings the word is also used for group sessions, courses and named methods, and it can mean very different things to different teachers.

A 2025 review of the field described it as fragmented because of the diversity of breathing techniques, and said research is limited by inconsistent study quality and methodological heterogeneity. [3] In plain terms: when someone says "breathwork helps", ask which practice, for whom, and compared with what.

This page is information only. Gentle practices are described only as far as health sources describe them. Forceful, rapid or breath-holding practices are described critically and are never instructions.

Types of breathing practice

Groups of practices sometimes called breathwork include:

• Gentle, slow and relaxation breathing. NCCIH lists breathing exercises among relaxation techniques and describes focusing on slow, deep breaths, also called diaphragmatic breathing. [4] The NHS gives a comfortable version: breathe gently and regularly into the belly, without forcing it. [5] See gentle breathing and relaxation practices.
• Traditional breath practices. NCCIH notes that yoga as practiced in the United States typically includes breathing techniques (pranayama), and that yoga is rooted in Indian philosophy. [6] Pranayama has its own texts, meanings and cautions; see pranayama, which treats it in its cultural context.
• Named clinical or therapy methods. A Cochrane review of breathing exercises for asthma lists the Papworth method, the Buteyko breathing technique, yogic breathing and deep diaphragmatic breathing as examples of interventions that manipulate the breathing pattern. [7]
• Intensive breathwork. This group includes practices built on fast, deep or repeated breathing, and on breath-holding. One example, the Wim Hof Method, was described in a systematic review as having three pillars: breathing, cold exposure and commitment. [8] That review, covering eight trials, found possible lowering of inflammation but mixed results for exercise performance and breathing measures, and its authors called for more study. [8]
• Awareness practices. Noticing the breath without changing it, as in some meditation. See breathwork, breathing exercises and breath awareness.

Gentle versus intensive

This split matters most for safety. Gentle practice stays comfortable and does not push your breathing away from its natural rhythm. Intensive practices deliberately push breathing faster, deeper or into holds. The body's reaction to overbreathing is documented: rapid, deep breathing lowers carbon dioxide in the blood and can cause lightheadedness, dizziness, weakness, chest pain or a pounding heartbeat, muscle spasms in the hands and feet, and numbness and tingling. [9]

For this reason this library gives no instructions for breath-holding, hyperventilation, or any breathing practice combined with cold or water. NCCIH advises yoga beginners to avoid extreme practices, including forceful breathing. [6] Never practice breathing exercises while driving, bathing, swimming, near water or at heights. The compare page gentle versus intensive breathwork and the guide to intensive breathwork go further.

What the research can and cannot say

The strongest summary we read is a meta-analysis of 12 randomized trials with 785 adults. It found a small-to-medium effect on self-reported stress (g = -0.35) compared with non-breathwork controls, and similar effects on self-reported anxiety and depressive symptoms. Most studies were at moderate risk of bias, and the authors urged caution about a miscalibration between hype and evidence. [1]

Two limits apply to almost every breathing trial. People cannot be blinded to the breathing they are doing, so expectations may shape results. And the main outcomes in that meta-analysis were self-reported, not objective measures. Label: promising but limited for stress and anxiety in general; each specific practice has its own label on its own page. See breathwork evidence overview.

Breathwork does not cure or prevent disease, and the sources we read do not support claims that it releases toxins or stored trauma. Proper evidence not found for those claims in the sources we read; our searches covered PubMed and the NCCIH, NHS and MedlinePlus pages cited here.

How the term is used commercially

The word is also used in marketing for classes, apps and retreats. Regulation of breathwork facilitators is not described in the sources we read for this page; see facilitator training and credentials for what we could verify. We do not list or recommend teachers, studios or apps.
