Daily 10-minute alternate-nostril breathing after two minutes of abdominal breathing,
does it really help with Lower six-week systolic pressure in treated adults with hypertension?
research showsGrade C with 50 points. In a trial with 91 randomized and 68 completing, six-week systolic pressure was 139.14±12.5 versus 147.79±12.8 mmHg, P<.01. Attrition was 25.3%, and the intervention was not alternate-nostril breathing alone: two minutes of abdominal breathing preceded ten minutes of Nadi Shodhana.
ads claimAlternate-nostril breathing alone is portrayed as replacing antihypertensive medication or normalizing autonomic function.
Useful facts when choosing a product
- The first two of 12 minutes were abdominal breathing.
- It was added to ongoing medication and lifestyle care.
- Sixty-eight of 91 randomized participants completed.
What the research actually shows
Adults with hypertension received standard management with or without the breathing program. The program combined two minutes of abdominal breathing with ten minutes of Nadi Shodhana; other pranayama or yoga programs were excluded.
Why this is classified as C (50)
One short SBP signal is limited by a surrogate endpoint, combined intervention, 25.3% attrition, small sample, and uncertain prespecification, giving C with 50 points.
Counterpoint. DBP was null between groups, and acute HRV studies were not counted as replication of six-week pressure effects.
Rejudgment record. Cross-check applied — Distinguished final SBP from adjusted change, DBP from HRV, and alternate-nostril breathing alone from the combined abdominal-breathing protocol
| Endpoint | S | Surrogate marker - laboratory or imaging measures |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | EX | The clinical size of the effect could not be judged |
The scoring table and the verdict agree (C).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Six-week SBP reduction as an adjunct | C | Final values differed, but adjusted effect and CI were unavailable. |
| Improved DBP or HRV | D | DBP was null and HRV varied by metric and study. |

|---|---|---|---|---|---|---|
| Study 1 | Randomized adjunct-to-standard-management trial | 68 | Reported public/academic support | Six-week SBP, DBP, and HRV | SBP 139.14±12.5 vs 147.79±12.8, P<.01; DBP P>.05 | Key six-week trial |
| Study 2 | Acute comparison with another pranayama | 100 | Academic research | Acute HRV | Between-group HRV was null | Indirect HRV qualifier |
