Box Breathing: Real Down-Regulation, Fake Navy SEAL Magic

Summary

Box breathing (the 4-4-4-4 count: inhale 4, hold 4, exhale 4, hold 4) is a genuine, free, zero-risk way to calm acute arousal in the moment — but it works because it **slows your breathing**, not because of the box shape, the equal ratio, or the breath-holds, and the "Navy SEAL technique" branding is marketing, not evidence; in the one head-to-head trial that tested it (Balban, 2023) it scored lowest of the three breathwork arms numerically, though the study was underpowered to compare the techniques, so it was not *significantly* beaten by the physiological sigh. ---
