Everybody breathes. Few do it right. Logic Breathing gives you 23 science-backed breathing patterns — each just 60 seconds. No 10-minute sessions. One minute to shift your nervous system. Why 60 seconds? Elite runners synchronize breath to stride in sub-minute cycles. Research on breathing cadence shows your autonomic nervous system responds in seconds, not minutes. We designed every pattern to deliver a measurable shift — in heart rate, cortisol, or mental clarity — before your coffee gets cold. One minute. One pattern. Pick your state: → Can't sleep — 4-7-8 Sleep (Dr. Andrew Weil's clinically studied technique) → Stressed before a meeting — Box Breathing (used by Navy SEALs) → Need to focus — Cyclic Sighing (Stanford-validated, outperformed meditation — Huberman et al., 2023) → Heart rate too high — Resonance Breathing (HRV optimization at 6 breaths/min) → Headache coming on — Headache Relief (relaxes cranial tension, boosts cerebral oxygenation) → About to train — Pre-Workout (sympathetic priming) → Spiraling — Calming Vortex (Fibonacci-inspired deceleration from agitation to calm) → Brain fog — Brain Fog pattern (sharpens cognition in under 60 seconds) → Plus 15 more for recovery, running, freediving, lifting, immune support, and craving control How it works: Pick a pattern. Press start. Follow the visual, audio, and haptic guide through each inhale, hold, and exhale.
