A guided breathing exercise tool to help you wind down before sleep. Follow the animated cue for inhale, hold, and exhale cycles — box breathing, 4-7-8, and more.
Open Sleep Breathing Guide → free, no sign-inControlled breathing before sleep — techniques like box breathing (4-4-4-4) or the 4-7-8 method — are clinically supported methods for activating the parasympathetic nervous system and reducing pre-sleep arousal. Following a rhythm without having to count in your head makes these techniques significantly more accessible. The Sleep Breathing Guide provides a simple animated cue that guides you through the inhale, hold, and exhale phases of each cycle.
Anyone who has trouble winding down before sleep, experiences pre-sleep anxiety, or wants a simple guided breathing practice without downloading a meditation app.
