4-7-8 Breathing Pacer

<p><strong>Why this helps:</strong> Slow, paced breathing with an extended exhale increases vagally-mediated heart-rate variability and shifts the body toward parasympathetic ("rest") activity; a controlled study of 4-7-8 breathing showed immediate heart-rate and blood-pressure changes, and a small paced-breathing trial before bed reduced sleep-onset latency and night awakenings (NCBI PMC9277512, 2022). A 2024 trial found 4-7-8 breathing improved self-reported sleep quality in COPD patients (Jurnal Respirologi Indonesia, 2024).</p><h4>Spoken script (4 cycles)</h4><p><span class="srp-cue">[slow]</span> We are going to breathe together. The pattern is simple. Breathe in for four. Hold for seven.
