If you need help right now

If anxiety feels unmanageable or you are having thoughts of harming yourself, call or text 988 in the United States (the 988 Lifeline says it is available 24/7/365). [1] Call 911 for chest pain or severe trouble breathing. Anxiety can feel physical, and some of its symptoms overlap with other conditions. [2]

Purpose of this page

This page summarizes research. It is not a treatment plan, and it does not replace care for an anxiety disorder. Guidance on anxiety itself is on anxiety disorders and therapy for anxiety and stress. For the practices behind the studies see gentle breathing and relaxation practices.

Self-help advice from health services

The NHS lists calming breathing exercises among things people with generalized anxiety disorder can try in their own time, alongside yoga or pilates. [3] Its breathing guide says the technique, which suits stress, anxiety and panic, takes just a few minutes, and asks you to let the breath flow into the belly as is comfortable, without forcing it. [4] These are practical suggestions from a health service, not proof of a treatment effect.

What the trials found

Source	What it studied	What it found	Main limits
Meta-analysis, 2023	Breathwork vs non-breathwork controls, adults	Small effect on self-reported anxiety (20 comparisons), similar to stress	Most studies at moderate risk of bias; authors urged caution
Small trial, generalized anxiety disorder, 2022	41 patients on medication and counselling, with or without breathing exercises	Anxiety differences were not significant	Small; breathing measures were a main focus
Systematic review, pranayama in adolescents, 2025	18 studies, 11 of them randomized	Lower anxiety and stress reported	Very low certainty (GRADE)
Meta-analysis, pranayama in medical students, 2026	7 studies, only 1 randomized	Large self-reported drop	Mostly single-arm; high heterogeneity
Meta-analysis, HRV biofeedback, 2017	24 studies, 484 participants	Large drop in self-reported stress and anxiety	Authors call for better-controlled studies

The 2023 meta-analysis found a small effect on self-reported anxiety, similar to its stress result. [5] One author had trained as a teacher with a breathwork foundation, which is worth knowing when reading the paper. [5] In the 2022 trial of 41 people with generalized anxiety disorder, those given breathing exercises on top of medication and routine counselling did not show significant anxiety differences. [6]

Pranayama, the breath practices of the Indian yoga tradition, has its own page: pranayama. A 2025 review of 18 studies in adolescents reported lower anxiety and stress, but graded the certainty of evidence as very low. [7] A 2026 review in medical students included just one randomized trial among seven studies, with high heterogeneity. [8] Both reviews suggest a possible benefit, but neither is strong evidence.

Breathing paced with feedback from heart rate (HRV biofeedback) is covered elsewhere on this site: see HRV biofeedback. A meta-analysis of 24 studies reported large reductions in self-reported stress and anxiety and said more well-controlled studies are needed. [9]

Why the evidence is hard to weigh

Breathing trials cannot be blinded, so expectation may shape self-reported anxiety. Many compare with waitlists or usual care rather than another active treatment, and self-reports are not objective measures. NCCIH notes that in reviews comparing relaxation therapy with cognitive behavioral therapy for anxiety disorders, most studies had a high risk of bias. [10]

Label: promising but limited for self-reported anxiety. Insufficient evidence that breathing alone treats an anxiety disorder.

Frequently asked questions

Do breathing exercises help anxiety?

Studies point to small improvements in self-reported anxiety, but with moderate risk of bias, and a small trial in generalized anxiety disorder found no significant difference. [5][6]

Which breathing exercise is best for anxiety?

Proper evidence not found. We searched PubMed for head-to-head trials comparing breathing techniques for anxiety and did not find one we could read, so we do not rank them.

Can breathing replace medicine or therapy for anxiety?

The sources we read do not show that. Reviews of relaxation therapy against CBT report mixed findings with high risk of bias. [10] Do not stop medicines without your prescriber.

Can breathing make anxiety worse?

Occasionally. NCCIH reports increased anxiety, intrusive thoughts or fear of losing control for some people using relaxation techniques. [10]

When should I get help for anxiety?

When it persists, affects daily life, or comes with chest pain, fainting or first-time rapid breathing. [10][12]

Side effects and cautions

Relaxation techniques are generally considered safe for healthy people, but occasionally people report increased anxiety, intrusive thoughts or fear of losing control. [10] If paying attention to your breath makes you more anxious, stop, return to normal breathing and consider a different approach. Never practice while driving, bathing or near water. Practices based on fast, forceful breathing or breath-holding are not recommended and are discussed critically on intensive breathwork. One review of such high-ventilation practices says reports of benefit invite further research rather than establishing it. [11]

Who should check with a clinician first

Check first if you have asthma or another lung condition, a heart condition, blood pressure problems, epilepsy, pregnancy, panic disorder, a trauma history, psychosis or bipolar disorder. Do not stop or change anxiety medicines because of a breathing practice.

When to seek care

MedlinePlus says to contact a provider if you are having rapid breathing for the first time, as it may be a medical emergency. [12] If anxiety persists, NCCIH says it is important to seek help from a qualified health care professional. [10]
