Anuloma Viloma Timer
Five minutes a day of long, slow exhales lifted mood more than meditation in a month-long trial.
That is the headline result of a 2023 paper from Stanford, published by Balban and colleagues in Cell Reports Medicine under the title “Brief structured respiration practices enhance mood and reduce physiological arousal.” Volunteers were assigned one of several five-minute daily practices for a month. One group did mindfulness meditation. The others did structured breathing, and one of those practices was what the researchers called cyclic sighing: a breath built around a long, unhurried exhale. Over the month, the cyclic sighing group showed a larger daily improvement in positive mood than the meditation group.
It is one study, with a modest number of people, done remotely, and it measured mood rather than any condition. It does not show that breathing treats anxiety or depression, and it should not be read that way. But it is a clean, controlled comparison, and it points at something specific: the part of the breath that seemed to matter was the way out.
The exhale was never the new part
Cyclic sighing is a new name. The idea that the out-breath should be longer than the in-breath is not.
Classical hatha yoga manuals describe pranayama in counts, and the counts are lopsided on purpose. The best-known ratio is 1:4:2: breathe in for one unit, hold for four, breathe out for two. The Gheranda Samhita, a 17th-century manual, gives it in matras (a traditional unit of time) as 16 in, 64 held, 32 out. Strip out the hold and you are left with the same instruction a modern lab arrived at: breathe out for twice as long as you breathed in.
The hold is the part that makes that ratio demanding, and it is the part beginners should approach slowly or leave out. The 1:2 underneath it is the gentle part, and it is where most teachers start students: a slow inhale through the nose, and an exhale that takes twice as long, without strain.
This is a pattern we keep running into. Slow breathing at about six breaths a minute was studied as “resonance breathing” decades after rosaries and mantras had people breathing at that pace. Nasal breathing became a trend long after hatha manuals told practitioners to breathe through the nose. Cyclic sighing is the latest name for a very old habit of the breath.
What the wider evidence says, honestly
It is worth keeping the Stanford result in proportion. A 2025 systematic review and meta-analysis in Frontiers in Psychiatry pooled randomised trials of pranayama for mental health conditions and found short-term benefit when it was added to usual care. The authors were careful about it: the trials were small, many had a high risk of bias, and they said pranayama should not replace standard treatment.
That is roughly where the honest summary sits. Slow breathing with a longer exhale is a reasonable thing to practise for a few minutes a day. People often report feeling calmer, and some controlled trials back that up. It is not a cure, and anyone with a heart, lung or blood pressure condition, or who is pregnant, should check with their doctor before adding breath holds.
How to practise the long exhale
You do not need a device, and you do not need to hold your breath.
- Sit down. Upright, shoulders soft, somewhere you will not be interrupted for five minutes.
- Breathe in through your nose for a slow count of four.
- Breathe out for a count of eight. Through the nose if that is comfortable, or through softly parted lips. Let it be smooth, not forced.
- Repeat for five minutes. If eight feels like a strain, use three in and six out. The ratio matters more than the numbers.
- Stop if you feel dizzy or lightheaded, and go back to normal breathing.
If you want to bring it closer to the traditional practice, do it as alternate nostril breathing: in through the left, out through the right for twice as long, then in through the right and out through the left. That is anuloma viloma at a 1:2 count, and it is a good place to stay for weeks before adding any hold.
When you are ready for a hold, keep it short, timed and seated. Our pacer video today walks through a single gentle round of 1:4:2: five seconds in, a twenty-second hold, ten seconds out. Never practise breath holds in or near water, and never breathe fast beforehand.
The point of going back to the source
There is nothing wrong with a new name. “Cyclic sighing” got a careful trial and a wave of attention that “breathe out twice as long” never had. But knowing where an idea came from changes how you use it. The old manuals did not treat the long exhale as a five-minute hack. They treated it as the foundation of a daily practice, built up patiently and measured by the count rather than the clock.
That is still a good way to approach it. Five slow minutes, a longer breath out, every day.
