Day 19 of the Minimal Mindfulness Guidance Challenge explores Square Breath - a structured breathing meditation that creates balance and calm. Through minimal cues, this practice guides you through a four-part breath cycle: inhale for a count of 4, hold that breath for a count of 4, exhale for a count of 4, and hold empty for a count of 4. This equal-sided breath pattern (like a square) regulates the nervous system and cultivates focused, rhythmic awareness.
