7 hoursA heavy debt: this is the territory where everything feels harder than it should.
How to pay it back
Do not attempt one heroic weekend. Add 30 to 60 minutes per night, let weekend mornings run about an hour longer, and a debt like yours clears in roughly 6 days.
Repaying sleep debt comes with a bonus: recovery nights are unusually rich in REM sleep, so expect vivid dreams and keep your journal close.
