Sleep Banking: Building a Buffer Before Sleep Loss — Yes — extending sleep before an anticipated period of sleep restriction (prophylactic sleep extension) genuinely protects alertness, reaction time, and mood relative to going in already depleted. It does not permanently store extra sleep, but it gives you a buffer that delays impairment. The protective effect on performance is supported by controlled experiments; full "repayment" of chronic sleep debt is more complex and likely incomplete. Use weekend recovery sleep — but limit the overshoot — A partial recovery sleep on weekends reduces acute cognitive debt but does not fully repay it — and large overshoots delay the Monday clock. Prevent bedtime creep: protect sleep duration at the start, not just the end — Debt accumulates most insidiously not from occasional late nights but from a bedtime that drifts 15 minutes later each week. Extend sleep before an anticipated shortfall — Sleep longer — 9–10 hours if you can tolerate it — for several nights before a period of known sleep restriction. Distinguish acute sleep loss from chronic restriction — A bad night and years of six-hour nights are entirely different physiological problems — treat them differently. Track and repay sleep debt intentionally — Know your weekly sleep debt and use weekend naps strategically to reduce it. Keep a daily sleep diary — Track sleep and wake times daily to reveal patterns and benchmark treatment progress. Use strategic naps to partially service acute sleep debt — A well-timed afternoon nap partially replenishes performance capacity on days following acute sleep loss. Use weekends to partially realign the clock — Allow yourself to sleep later on free days — but not so much later that it creates re-entry jetlag. Use the bed only for sleep (and sex) — Reserve the bed strictly so the brain learns to associate it with sleepiness, not wakefulness.

Does this sound like the set of challenges you might be facing?

I drag through the week on too little sleep and then crash for half of Saturday to catch up, but Monday somehow feels worse than ever
My wake time never moves but my bedtime keeps sliding a little later every week without me really noticing, and I think that quiet drift
I can see the wall coming
I’ve been running on six hours a night for years and I tell myself I’m used to it and one good weekend resets me
I’ve been running on short nights all week and it’s catching up with me in a way coffee can’t fix anymore
