Wind Down
“Work is over. I want to actually arrive in my evening.”
60-90 minutes before bed — you're still working, lights still on, transitioning out of work mode.
What success looks like
You exit the protocol still alert enough for evening activities (cooking, reading, partner conversation, kids) but no longer in "work" nervous-system state.
Reach for it when
- End of workday transition
- Pre-evening, post-work decompression
- When work keeps spilling into evenings
- Setting a work/life boundary
- Coming back to family / partner / self
The science
Exhale-Biased Breath + Light Body Scan + Detachment Practice
Wind Down is a 15-minute structured transition from work-mode to evening-present state. The dominant evidence-bearing component is *psychological detachment from work*, not the specific breath count.
1. Psychological detachment (Sonnentag & Fritz 2015 meta-analysis). End-of-day detachment from work predicts better sleep quality, less fatigue, and better next-morning affect across multiple day-level diary studies. The protocol's closing step — naming residual work concerns and intentionally leaving them for tomorrow — is the operationalization of detachment.
2. Exhale-biased breathing. Default is 4-in / 6-out symmetric-ish (no breath holds), which has reproducible vagal activation effects (Russo 2017) and avoids the breath-hold contraindications of 4-7-8. Advanced users who tolerate breath holds can opt for 4-7-8 — Vierra 2022 showed single-session 4-7-8 raised HF-HRV and lowered HR and blood pressure in healthy adults.
3. Light body scan as somatic release marker. Distinct from Yoga Nidra rotation by intention and depth — the goal is to cue "the body is leaving the workday," not to induce deep rest.
What this protocol does NOT do. An earlier version called 4-7-8 the "standard wind-down breathwork" and claimed the 15-minute duration "matches the natural transition time for cortisol to begin its evening decline." Neither claim holds up:
- Cortisol declines *gradually* all day from the post-waking peak; there is no discrete "evening decline window" the protocol is capturing. The 15-min figure has no circadian basis.
- 4-7-8 is not the strongest-evidenced wind-down breath. Balban 2023 (Stanford / Huberman) compared box breathing, cyclic sighing, cyclic hyperventilation, and mindfulness — cyclic sighing won for mood and arousal. We kept 4-7-8 as an advanced option (it has cultural fit and meaningful evidence) but defaulted to the safer 4-6 exhale-biased variant for all users.
When NOT to use this
This protocol may be the wrong tool — or need care — for:
- Pregnancy — modify any breath-hold patterns (4-7-8 → 4-4-8 or use the 4-in/6-out variant without holds, which is the default).
- Hypertension or cardiovascular conditions — extended breath holds are not advised. Use the 4-in/6-out variant without holds.
- Panic disorder or high anxiety sensitivity — breath holds can precipitate panic. Stay with 4-in/6-out.
- Severe end-of-day fatigue + supine position — this is a documented micro-sleep trigger. Stay upright (chair or couch sitting). If you keep falling asleep mid-protocol, switch to Sleep In and just go to bed.
This is not medical advice. If any of these describe you, talk to your clinician before integrating this protocol.
