Special tips for shift workers & jet lag

Module 01 — Environment

Build Your Sleep Cave

Your environment is the foundation of quality sleep. Treat your sleep space as sacred — a sensory deprivation chamber designed for one purpose only.

🌑
Darkness
Complete blackout. Blackout curtains, tape over LEDs, eye mask if needed.
❄️
Temperature
60–67°F (15–19°C). Cool body = faster sleep onset and deeper stages.
〰️
White Noise
Masks irregular daytime sounds. Fan, machine, or app all work.
📵
Phone Off
Not silent. Off — or in another room. Blue light disrupts melatonin.
🚿
Hot Shower
~104°F (40°C) for 10 min, 1–2 hrs before bed. Hot water causes vasodilation — blood rushes to the skin, rapidly cooling your core. It's that temperature drop that triggers sleep onset.

⚠️ Also avoid before sleep:

  • Caffeine last 4–6 hrs of shift
  • Heavy meals close to bedtime
  • Bright screens (TV, phone, tablet)
  • Alcohol — fragments sleep cycles

Module 02 — Psychology

Let Go of Perfect Sleep

The harder you try to force sleep, the further it retreats. This is sleep performance anxiety — and it's extremely common among shift workers.

"Worrying about imperfect sleep increases arousal and makes sleep worse. Accept that some nights won't be great — and that's okay."

The most powerful shift you can make is moving from effort to acceptance. Imperfect sleep is still restorative. Your body knows what to do.

✓ Imperfect sleep still repairs ✓ Anxiety worsens sleep more than noise ✓ 5 hrs beats 0 hrs stressed in bed ✓ Your body catches up naturally

Module 03 — Wind-Down Routine

Scheduled Worry Protocol

Done 5–10 minutes before sleep, this sequence offloads mental load so your brain stops patrolling and starts resting. Tap each step to expand.

  • 1
    Brain Dump
    3 MIN
    Tap to read more
    Write everything on your mind. Don't organize, categorize, or solve — just transfer it from brain to paper. This externalizes the "mental patrol" that keeps you awake.
  • 2
    Tomorrow's Top 3
    1 MIN
    Tap to read more
    List exactly 3 priorities for tomorrow. No more. This creates psychological closure — your brain stops ruminating because it now has a plan. The open loop is closed.
  • 3
    Thought Defusion
    2 MIN
    Tap to read more
    Notice thoughts without engaging them. Label each one: "That's my work worry." "That's my to-do brain." Watch them pass like clouds. You're the observer, not the thought.

Module 04 — Breathwork

4-7-8 Breathing

This ratio activates your parasympathetic nervous system — the body's rest-and-digest mode. The extended exhale is the key mechanism that slows heart rate.

Module 07 — Shift Workers

After Night Shift — Top 3 Strategies

Everything in this guide applies — but shift workers face unique challenges: sleeping against your circadian rhythm, daytime noise and light, and inconsistent schedules. These three strategies make the biggest difference.

1
Blue-Blocking Glasses
Wear on your commute home. Blocks the melatonin-suppressing light that signals daytime to your brain and delays sleep onset.
2
Nap During Shift
Any 20–30 min nap helps — earlier in your shift may be better. For 16-hr shifts, aim for 90 min total nap time. Allow 10–15 min after waking before critical tasks (sleep inertia window).
3
Sleep Soon After Shift
Get to sleep within 1–2 hours of arriving home. Keep timing consistent on work days — your body anchors to rhythm, even a shifted one.

Module 08 — Jet Lag

Traveling Across Time Zones?

Use timed light exposure to reset your clock faster. Outdoor light works best — even on cloudy days. A light therapy box works indoors too.
