What is Dirga Pranayama?

Thin and early-stage. The clearest direct finding comes from one small study of 30 middle-aged women in Bangalore, whose triglyceride levels, a blood fat, fell after six weeks of daily practice compared with a no-training group. That study reported no effect size or confidence interval and has not been repeated (Yoga & Yoga, 2023). The calmer, more settled states people usually seek are supported by slow-breathing research broadly, not by trials of Three-Part Breath itself, so those calming benefits remain unconfirmed for this technique specifically (Yoga & Yoga, 2023).

Two ways, both plausible rather than directly demonstrated for Three-Part Breath. First, attentional anchoring: following the breath as it moves through the lower belly, then the ribs, then the upper chest gives your attention a clear, physical target, which tends to crowd out rumination and keep focus in the present. Second, slow diaphragmatic breathing is thought to engage the vagus nerve and shift the body toward the parasympathetic, rest-and-recovery branch of the nervous system, felt as the breath lengthening and the muscles softening on their own. Both mechanisms come from broader slow-breathing research; the one study specific to this technique measured blood triglycerides rather than calming or nervous-system outcomes, so the pathway is best read as a plausible mechanism, not yet confirmed for Dirga Pranayama (Yoga & Yoga, 2023).

Usually because the breath is being pushed a bit too deep. Deliberately fuller breathing can briefly lower blood carbon dioxide, a state known as hypocapnia, and that dip can produce mild, passing lightheadedness or tingling in the hands or face, especially in your first few sessions. This is inferred from how over-breathing works rather than measured in a study of Three-Part Breath specifically, but it is generally normal and self-limiting: practise seated or lying down, keep the breath comfortable rather than maximal, and pause to breathe normally until the sensation passes.

Use care. Three-Part Breath is low-risk for most healthy adults, but focusing on the breath and on internal sensations can feel destabilising for some people with panic or trauma histories and may increase distress before it settles. This is a practice-informed, mechanism-inferred caution rather than a measured finding, because no trial has studied the safety of this technique in these situations. If breath focus feels activating, keep sessions brief, open your eyes, return to easy natural breathing, and consider working with a qualified teacher or clinician. It is not a substitute for care when panic or trauma is significant.

Start with just a few minutes. There is no technique-specific research on how long to practise, so the sensible approach is practical: begin short, keep the breath easy rather than forced, and extend your sessions gradually over days and weeks as the practice feels comfortable. If lightheadedness, tingling in the hands or face, or a floaty feeling shows up, pause and let normal breathing return. This is conservative, practice-informed guidance rather than a measured dose.

The main difference is what your attention rests on. Box breathing anchors on a timed rhythm with short breath-holds between each phase, which some people find grounding but which can feel activating for anyone prone to panic or air-hunger. Three-Part Breath drops the counting and the holds altogether, anchoring instead on the moving sensation of the belly, ribs, and chest filling and releasing in order, which suits people who prefer following bodily feeling to a fixed count. No study has tested the two side by side, so neither is established as better, and neither treats anxiety or a diagnosed condition; the choice is mostly about which anchor feels more natural.
