Breathwork Timer

What is Breathwork?

Breathwork is controlled breathing — deliberately timed inhales, holds, and exhales to shift how your body and mind feel. A longer exhale than inhale activates the parasympathetic nervous system, slowing heart rate and reducing perceived stress. A rapid rhythmic breath does the opposite, raising alertness and energy. Different techniques use these levers in different combinations, which is why 4-7-8 calms you down while Wim Hof breathing wakes you up.

How to Use This Breathing Timer

Pick a technique, hit Start, and let the visual guide do the pacing. The breath circle expands on inhale, holds if there's a hold phase, and contracts on exhale. Audio cues let you close your eyes and follow along without watching the screen. Adjust the inhale, hold, and exhale durations — or the number of cycles — in the settings panel.

Breathing Techniques Explained

Box Breathing (4-4-4-4) is what Navy SEALs and ER nurses use to stay composed under pressure — four equal sides, like drawing a square with your breath. The 4-7-8 technique, from Dr. Andrew Weil, uses a long hold and a double-length exhale to activate the relaxation response fast. Resonance Breathing at 5.5 breaths per minute is the rate that maximises heart rate variability (HRV), a measure of cardiovascular flexibility. The Physiological Sigh — two quick inhales through the nose then a slow exhale — is clinically the fastest way to reduce real-time stress.

Benefits of Regular Breathing Practice

Five minutes of daily breathwork reduces cortisol, lowers resting heart rate, and improves sleep onset. A 2023 Stanford study measured cyclic sighing (structured exhale-emphasis breathing) against mindfulness meditation for four weeks. The breathing group reported greater daily mood improvement. You don't need a meditation practice — you just need to breathe on purpose, once a day.
