The protocol
The Protocol That
Beats Sleeping Pills.
CBT-I has five evidence-based components. SleepShift delivers all five in a structured 8-week sequence. Here's exactly what happens and why it works when nothing else has.

Sleep Restriction Therapy
Your time in bed is deliberately matched to your actual sleep time — not your desired sleep time. This rebuilds sleep pressure (the biological drive to sleep) which chronic insomnia depletes.
Sleep restriction is among the most effective single components of CBT-I — and a key mechanism behind the protocol's durable results, with benefits sustained at 24-month follow-up (Morin et al., JAMA 1999).
How SleepShift applies it
After about two logged nights of sleep diary data, the app calculates your average Total Sleep Time and sets your provisional sleep window — confirmed around night five as more data comes in. If you're sleeping 5.5 hours on average, your window is 5.5–6 hours. As your sleep efficiency rises above 85%, your window extends in 15-minute steps.
What to expect in Phase 2
Clinical safety floor
The sleep window is never set below 5.5 hours, regardless of baseline TST — consistent with published sleep-restriction protocols, reviewed by Dr. Candice Seti, Psy.D.
Stimulus Control
Chronic insomnia trains your brain to associate the bed with wakefulness, alertness, and anxiety through classical conditioning. Stimulus control breaks that association by re-establishing the bed as a cue exclusively for sleep.
Stimulus control is one of the most evidence-supported single components of CBT-I, producing large improvements in sleep-onset latency across meta-analyses.
The five rules
- Use the bed only for sleep and sex. No screens, no reading, no lying awake thinking.
- Go to bed only when you're sleepy — not just tired, but genuinely sleepy.
- If you can't sleep within ~20 minutes, get up. Go to a dimly lit room.
- Return to bed only when you feel sleepy again. Repeat if needed.
- Set a consistent wake time every morning. Do not vary it by more than 30 minutes, including weekends.
How SleepShift applies it
Daily behavioral checklist in-app. Morning reminders calibrated to your wake anchor. Compliance is logged alongside diary data — patterns (e.g., consistently skipping the get-up rule) surface in your weekly protocol review.
Sleep Diary
The sleep diary is the data source for everything in the protocol. Every morning, you log the previous night. The algorithm runs on this data — not estimates, not wearables, not averaged guesses.
Prospective sleep diaries are the foundation of clinical insomnia assessment. SleepShift starts with a provisional window after about two logged nights and keeps refining it as your diary grows. Studies show subjective diary data correlates strongly with polysomnography for the specific metrics CBT-I uses.
What you log each morning (under 60 seconds)
Why accuracy matters
Sleep restriction and window adjustments are calculated entirely from your diary data as it comes in. A skipped entry means the algorithm works with incomplete information. The diary is only as accurate as what you give it — and the protocol is only as effective as the diary.
Sleep Efficiency Tracking
Sleep efficiency is the percentage of your time in bed that you're actually asleep. It's the single most clinically important metric in the protocol — it drives all window adjustment decisions and is the primary outcome measure in CBT-I trials.
Healthy sleepers maintain 85%+ sleep efficiency. CBT-I produces roughly a 10-point sleep-efficiency gain on average (Trauer et al., Annals of Internal Medicine 2015) — over the program you watch your efficiency climb toward the 85–90% target.
The formula
≥ 85%
Window extends +15 min
75–84%
Window maintained
< 75%
Window reduces slightly
What consistent improvement looks like
If your sleep efficiency over your last 7 days is 85% or higher, your sleep window extends by 15 minutes. This continues phase by phase until your window matches your natural sleep need. Most participants reach a 7–8 hour window by Phase 7–8.
Cognitive Restructuring
Identifying and reframing the thought patterns that perpetuate insomnia. Catastrophizing, clock-watching anxiety, sleep performance anxiety — these thoughts are as much a driver of chronic insomnia as the behavioral patterns, and they create the hyperarousal that makes sleep physiologically harder.
The cognitive component of CBT-I addresses the '3P model' of insomnia: predisposing, precipitating, and perpetuating factors. Studies show cognitive interventions reduce sleep-related arousal and pre-sleep cognitive activity — both key perpetuating factors.
Common distortions CBT-I targets
Catastrophizing
"If I don't sleep tonight, I'll be completely useless tomorrow."
Clock anxiety
"It's 2:30 AM. I've only slept 3 hours. I'm ruined."
Sleep performance anxiety
"I have to sleep perfectly tonight or the whole week is ruined."
Selective attention to symptoms
"I always notice when I feel tired. This proves I'm not getting better."
How SleepShift applies it
Structured AI-assisted prompts, not free chat. Starting Phase 3, weekly guided sessions target specific distortions based on your diary data and progress. Each session takes 10–15 minutes and is grounded in the specific patterns CBT-I research identifies.
What SleepShift does not do
SleepShift is appropriate for adults with primary chronic insomnia — difficulty falling or staying asleep that has persisted for 3+ months and is not primarily caused by another medical or psychiatric condition. If you're unsure, talk to your doctor before starting.
