Five Minutes a Day

Working adults do not have a spare half-hour. They have five minutes between meetings, and they want to know whether that sliver does anything. This PRISMA-2020 systematic review asked how large the effect of breathing practices of five minutes or less is on stress and mood, acutely and after daily practice. A quantitative meta-analysis is not yet possible: six eligible controlled datasets (approximate unique n = 340) were found for 2010–2026, but designs, comparators and time-frames were too heterogeneous to pool under a random-effects model without inventing a number the data do not support. The clearest four-week signal remains Balban and colleagues (2023): 108 non-clinical adults practised five minutes a day for 28 days. All arms, including mindfulness, improved state anxiety. Breathwork, especially cyclic sighing, produced a larger daily rise in positive affect (about +1.91 versus +1.22 points) and a larger fall in resting respiratory rate. One-minute cyclic sighing and box breathing, delivered in real threat moments, also cut state anxiety versus a passive control in a 2026 field pilot. A first laboratory session of slow-paced breathing can raise perceived stress in novices, which is the opposite of the brochure and matters for onboarding. Certainty is low to moderate for acute subjective calming, low for a four-week mood advantage over mindfulness, and absent for Indian working adults at this exact dose. No completed CTRI trial of isolated ≤5-minute breathing in non-clinical professionals was identified. The practical reading for an Indian workplace programme is modest and useful: five minutes is a countable rep, not a miracle; the first minute appears to carry much of the acute feel; daily practice for four weeks is the only duration with a head-to-head trial against mindfulness; and local evidence still needs to be built.
