Weekly Sleep Log

The arithmetic

WEEK'S SHORTFALL

target x 7 − hours actually slept

Weekday loss

add the Mon-Fri nights that fell short

Weekend recovery

add the Sat-Sun nights that went over

Average shortfall

target − (week total ÷ 7)

45 min a night

is 5.25 hours a week — most of a night

⚠ Two weekend nights

cannot repay five weekday ones

⚠ Recovery is not hour-for-hour

the ledger is a metaphor, not physiology

⚠ Target is YOURS

published figures are population ranges

⚠ Unrefreshed after a full night?

that is a clinician question, not a sum

What I will change on WEEKDAYS

Logging it honestly

• Recorded time ASLEEP, not time in bed
• Filled in each morning rather than reconstructed on Sunday
• Target set from how I feel, not from a published figure
• Tracker figures treated as estimates, not measurements
• Looked at the nights-below-target COUNT, not just the total
• Change planned for WEEKDAY nights, where the deficit is built
• Repeated weekly — one week is an anecdote, a month is a pattern
• Persistent unrefreshing sleep or snoring raised with a clinician

The weekend cannot carry the week

Five weekday nights can lose six or seven hours between them; two weekend nights can recover one or two, because there are only two of them and nobody sleeps fourteen hours in one. That is arithmetic before it is physiology — and the physiology does not help either, since recovery sleep is not a straight hour-for-hour exchange for what was missed.

Small gaps, quietly

Forty-five minutes a night sounds like nothing and comes to 5.25 hours across a week — most of a full night, lost without any single evening feeling like a decision. That is why sleep debt accumulates unnoticed, and why the average nightly shortfall is usually more useful than the weekly total.
