Effects of Diaphragmatic Breathing on Health: A Narrative Review

Open access
Hamasaki, Hidetaka·2020·Medicines

Abstract

Background: Breathing is an essential part of life. Diaphragmatic breathing (DB) is slow and deep breathing that affects the brain and the cardiovascular, respiratory, and gastrointestinal systems through the modulation of autonomic nervous functions. However, the effects of DB on human health need to be further investigated. Methods: The author conducted a PubMed search regarding the current evidence of the effect of DB on health. Results: This review consists of a total of 10 systematic reviews and 15 randomized controlled trials (RCTs). DB appears to be effective for improving the exercise capacity and respiratory function in patients with chronic obstructive pulmonary disease (COPD). Although the effect of DB on the quality of life (QoL) of patients with asthma needs to be investigated, it may also help in reducing stress; treating eating disorders, chronic functional constipation, hypertension, migraine, and anxiety; and improving the QoL of patients with cancer and gastroesophageal reflux disease (GERD) and the cardiorespiratory fitness of patients with heart failure. Conclusions: Based on this narrative review, the exact usefulness of DB in clinical practice is unclear due to the poor quality of studies. However, it may be a feasible and practical treatment method for various disorders.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Evening exposure to bright or blue-enriched light suppresses melatonin production, delays sleep onset, and reduces overall sleep efficiency, whereas warm, dim lighting and blue-light filters during evening hours minimize circadian disruption.

    “Systematic reviews and meta-analyses demonstrate that evening exposure to bright or blue-enriched light suppresses melatonin production, delays sleep onset, and reduces overall sleep efficiency by signaling the brain to remain alert, whereas warm, dim lighting and blue-light filters on electronic devices during evening hours minimized circadian disruption [49].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
