The Physiology of Sleep Onset

To transition into Stage 1 sleep, heart rate must drop and core body temperature must decrease. Extended exhalations directly stimulate the vagus nerve (via Respiratory Sinus Arrhythmia), forcefully applying the "vagal brake" to the heart.

Protocol 1: 4-7-8 Breathing (Dr. Andrew Weil)

  1. Exhale completely through your mouth, making a whoosh sound.
  2. Close your mouth and inhale quietly through your nose to a mental count of 4.
  3. Hold your breath for a count of 7.
  4. Exhale completely through your mouth, making a whoosh sound to a count of 8.
  5. Repeat the cycle four times.

Protocol 2: Extended Exhale (1:2 Ratio)

A simpler, safer approach if holds cause anxiety.

  1. Inhale strictly through the nose for 4 seconds.
  2. Exhale slowly through the nose (or pursed lips) for 8 seconds.
  3. Repeat for 5-10 minutes.

Common Mistakes

Using chest/apical breathing. If your shoulders move up, you are signaling stress. Ensure the movement is entirely in the lateral ribs and belly.
