5 nights

Sleep Wind-Down

Evening-focused 4-7-8 and extended-exhale protocols that pull you into parasympathetic before bed.

What this program does

Sleep Wind-Down rotates through two extended-exhale variants across five nights. The first three are 4-7-8 — four-second inhale, seven-second hold, eight-second exhale. The last two switch to 4 in / 12 out — pure extended exhale, no retention. Together they teach the body to recognize the 'lights out' cue at a physiological level.

Built for

Anyone whose mind speeds up the moment their head hits the pillow. People winding down from screen-heavy days.

What to expect

Most users report meaningful improvement in time-to-sleep after the second or third night.

Day by day

  1. Day 1

    4-7-8 · 3 min

    Four cycles. Lying in bed, lights low. Stop after the fourth — first session can be strong.

  2. Day 2

    4-7-8 · 5 min

    Five to six cycles. Notice that the second cycle does most of the work.

  3. Day 3

    4-7-8 · 5 min

    Same as last night. Repetition is the point.

  4. Day 4

    Extended Exhale 4/12 · 5 min

    Drop the hold. Pure long exhale. Continuous and quiet.

  5. Day 5

    Extended Exhale 4/12 · 7 min

    The protocol you can return to nightly. Builds slowly into habit.
