Our Content Methodology

How we create evidence-based breathing guides you can trust.

Last updated: January 27, 2026

Our commitment

Deep Breathing Exercises provides free, evidence-informed breathing techniques and guides. We believe accurate health information should be accessible to everyone. Our content aims to be helpful, accurate, and transparent about what research does and doesn't support.

Research standards

Our content is informed by:

  • Peer-reviewed research: We prioritize systematic reviews, meta-analyses, and randomized controlled trials from journals indexed in PubMed and PsycINFO.
  • Established protocols: We reference techniques from recognized researchers like Dr. Andrew Weil (4-7-8 breathing), Dr. Andrew Huberman (physiological sigh), and Mark Divine (box breathing).
  • Clinical guidelines: We align with guidance from organizations like the American Heart Association, Sleep Foundation, and Cleveland Clinic where applicable.

Editorial process

  1. 1
    Research phase

    We review scientific literature, identify consensus findings, and note areas of ongoing research or uncertainty.

  2. 2
    Content creation

    We write clear, accessible content that explains techniques, benefits, and appropriate use cases—always grounded in research.

  3. 3
    Accuracy review

    Content is reviewed for accuracy, clarity, and appropriate safety disclaimers before publication.

  4. 4
    Ongoing updates

    We regularly review and update content as new research emerges. All pages display their last update date.

What we include

  • Source citations: Each technique page includes references to supporting research with links to PubMed or original sources.
  • Safety information: We include appropriate cautions, contraindications, and recommendations to consult healthcare providers when relevant.
  • Last updated dates: Every page displays when it was last reviewed and updated.
  • Evidence levels: We distinguish between well-established findings (multiple RCTs) and emerging research (preliminary studies).

What we don't do

  • We don't provide medical diagnoses or treatment recommendations.
  • We don't claim breathing techniques can cure diseases or replace medical treatment.
  • We don't overstate research findings or present preliminary studies as established fact.
  • We don't recommend techniques for conditions where research doesn't support their use.

Our team

Deep Breathing Exercises is created by Abiassi and Darkmatter AI Labs. Our content is informed by consultation with breathing practitioners, review of scientific literature, and feedback from users.
