Galpin presents sleep restriction training as an effective but brutal option that his team uses infrequently. The method fixes wake time, sharply limits the initial window allowed in bed, and removes sleeping in or compensatory naps. This creates concentrated sleep pressure and retrains the association: getting into bed should predict falling asleep and remaining asleep. Once sleep consolidates, the bedtime moves earlier by roughly 10 to 15 minutes each week while wake time remains fixed. The sleep window is gradually backfilled until adequate duration returns without recreating long periods awake in bed. Galpin explicitly cautions that this is an extreme example, does not recommend it casually, and says people with legitimate health concerns should involve a physician.
Origin
Galpin describes sleep restriction training as a clinical-style method his team has used selectively. Extracted from The Diary of a CEO.
Core principles
- 01Repeated wakefulness in bed can become a learned pattern.
- 02A fixed wake time helps establish a stable sleep opportunity.
- 03Time in bed expands only after sleep becomes consolidated.
- 04The protocol is demanding and is not a casual sleep hack.
How to run it
- 1
Screen for suitability
Discuss the pattern, health concerns, medication, daytime safety, and alternative causes with a qualified professional before restricting sleep.
Pro tip Use less severe pattern-breaking methods when they are sufficient.
Watch out Severe sleepiness can create driving, workplace, and health risks.
- 2
Anchor wake time
Set one wake time and keep it every day, including weekends, according to the supervised plan.
Pro tip Treat wake time as the non-negotiable anchor.
- 3
Set the sleep window
Delay bedtime to create a deliberately compressed opportunity for sleep. Do not enter bed early simply because fatigue is high.
Watch out The transcript's five-hour example is an extreme illustration, not a universal prescription.
- 4
Protect consolidation
Avoid sleeping in and unplanned naps so that the new bed-sleep association can strengthen.
Pro tip Track time asleep rather than judging the process from one difficult night.
- 5
Expand gradually
When sleep is consolidated, move bedtime earlier by about 10 to 15 minutes for the next week while preserving wake time.
Pro tip Reverse the expansion if prolonged wakefulness returns and consult the supervising professional.
- 6
Restore adequate duration
Continue gradual expansion until the person has a sufficient sleep window and a stable pattern.
Pro tip The goal is adequate consolidated sleep, not permanent restriction.
In the wild
Galpin imagines someone who must rise at 5 a.m. but spends much of the night awake. In his extreme example, bedtime is held until 11:59 p.m., wake time remains 5 a.m., and no naps or weekend sleeping-in are allowed. After consolidation, bedtime moves earlier by 10 to 15 minutes per week.
→ The example shows how a compressed window is gradually expanded after the bed-sleep association changes.
Common mistakes
Copying the extreme window
The five-hour window is an illustration, not a safe universal starting point.
Expanding too quickly
Adding large amounts of time in bed can reintroduce the wakeful pattern the protocol is trying to change.
Is it for you?
Best for
Appropriately screened adults using sleep restriction as part of professional insomnia care.
Not ideal for
Unsupervised use by people with medical concerns, safety-critical fatigue risks, or conditions a clinician has not assessed.
From the transcript
“there's a thing called Sleep restriction training”
“every week then you add back 10 to 15 minutes”
“I don't recommend doing it especially if you have legitimate health concerns”
