Anuloma Viloma TimerA 2025 randomised waitlist controlled trial of online conscious connected breathwork just reported a Cohen’s d of 1.44 on standardised anxiety scales. Most anxiety drug trials report effect sizes of 0.3 to 0.5. That gap is not a rounding difference. It is roughly the gap between a clinically interesting intervention and a category-redefining one.
The trial was published in January 2026 in the Journal of Affective Disorders. 107 adults, mean age 41, randomised to either six weekly 90-minute online group breathwork sessions or a waitlist control. The breathwork group reduced their anxiety scores by more than 10 points on the standardised measure used. The control group moved less than 2 points. The mechanism the authors cite: vagus nerve stimulation, increased cortical blood flow, and facilitated emotional processing through the circular breathing structure they used.
A 1.44 effect size is large enough that the average person in the breathwork group ended the six weeks below the score of the bottom 92 percent of the control group. To put that in context, sertraline, paroxetine, and venlafaxine, the workhorse anxiety drugs of the last twenty years, report effect sizes between 0.3 and 0.5 in their own pivotal trials. Cognitive behavioural therapy, the most studied non-pharmacological intervention, lands between 0.5 and 0.8 depending on the meta-analysis you read. A 1.44 is not in the same neighbourhood as those numbers.
Two important caveats. The protocol the trial tested is conscious connected breathwork, a circular breathing pattern without pauses, typically delivered in a 60 to 90 minute group session with somatic and emotional intensity. This is not Anuloma Viloma. The two practices share a category, structured breathing as nervous-system regulation, but they are different techniques. Anuloma Viloma is structured bilateral nasal breathing with intentional retention, the alternate-nostril practice named in yogic texts long before any modern protocol existed. The 2026 trial is evidence that breathwork as a category produces large anxiety effects, not evidence that this exact app’s protocol does.
The second caveat is sample size. 107 adults split across two arms is enough to clear statistical significance, not enough to call the result robust across populations. The authors are explicit about this. A replication at scale is what the field needs next, ideally with active control rather than waitlist control to disentangle expectation effects.
What is striking about this trial is not that breathwork helped. There are now 44 randomised trials in the systematic review literature pointing the same direction. What is striking is the magnitude. For most of the last decade, breathwork research has been quietly producing medium-to-large effect sizes that the popular wellness conversation has not caught up to. The 1.44 figure is the largest single number published in the modern literature on this category. As of this week, no major wellness outlet has covered it.
For Anuloma Viloma practitioners, the practical implication is narrow but real. The 1.44 number is not a guarantee that a daily five-minute alternate-nostril session produces the same result as six 90-minute group breathwork sessions. It cannot. But it puts the category the practice sits inside on a different footing. When a structured breathwork protocol clears 1.44 in a controlled trial, the prior probability that a related structured technique, repeated daily, produces meaningful nervous system effects, is no longer in doubt.
The 2026 paper also points back at something Anuloma Viloma’s daily users describe in plainer language. The first time you finish a structured five-minute alternate-nostril session, something in the body settles. The breath has slowed. The shoulders are lower than they were. The thought you started the session with is still there but it is no longer driving. That feeling has a measurable shape. The 1.44 trial is one of the first numbers we have for it.
Two other studies are worth knowing about in the same window. A 2026 paper in the International Journal of Indian Psychology reported a 40 to 50 percent reduction in anxiety and depression scores in panic disorder patients using Bhastrika and Anulom Vilom breathing. A 2026 paper in Counselor Education and Supervision reported measurable wellness improvements in a counselor-training cohort using a virtual breathwork protocol. None of these are headline news yet. They will be.
What does it look like to fit a structured daily practice into this. Five minutes of alternate-nostril breathing, done seated, with eyes closed or open, using the structured timer in Anuloma Viloma Timer to count the inhale, the retention, the exhale, and the retention on the other side. The technique was named in the Hatha Yoga Pradipika in the fifteenth century, and in older yogic texts that predate the common era. It has the longest peer-reviewed track record of any breathwork pattern. The 2026 trial is one more piece of evidence that the category it belongs to is not fringe medicine.
The number to remember is 1.44. The technique to try is the one that named the practice first.
