Week 1 — Assessment & Education

🪮 Sleep science

Sleep architecture
Normal sleep cycles through lighter non-REM stages and REM sleep. Brief awakenings are common and not automatically a failure.
Homeostatic sleep drive
The longer you stay awake, the stronger the pressure to sleep. Naps and extended time in bed weaken this pressure and maintain insomnia.
Circadian rhythm
Your body clock controls alertness across a 24-hour cycle. A fixed rise time stabilises this rhythm faster than any other single change.
The 2-process model
Sleep timing reflects homeostatic pressure (Process S) and circadian timing (Process C). CBT-I works by restoring alignment between these two forces.

📈 Titration rules

Extend +15 min if SE ≥ 85% for 5+ of last 7 nights.
Hold window if SE 80–84%.
Reduce −15 min if SE < 80% for 3+ nights. Min window: 5 hours.

🌍 Stimulus Control (Bootzin rules)

  1. Go to bed only when sleepy.
  2. Use the bed only for sleep or sex.
  3. If awake 15–20 min, get out of bed.
  4. Return to bed only when sleepy again.
  5. Wake at the same time every day.
  6. No napping.

🦁 Relaxation techniques

Press Start to begin guided PMR sequence.

4s inhale — 7s hold — 8s exhale

Press Start for a gentle body scan from feet to head.
Paradoxical intention: Instead of trying hard to fall asleep, gently allow yourself to remain quietly awake without effort. Reducing performance anxiety can allow sleep to come more naturally.

📝 Practice notes

  • Treat relaxation as a skill to practice — not a test to pass.
  • If relaxation increases frustration, stop and use stimulus control instead.
  • Practice PMR outside of bedtime first for best effect.
  • 4-7-8 breathing activates the parasympathetic nervous system.
