Recommended baseline for your age.
Shortfall per 24-hour cycle.
Accumulated weekend deficit.
Getting less than 7 hours of sleep impairs glucose tolerance and reduces muscle protein synthesis. Moving bedtime 30 minutes earlier is the single highest-yield recovery intervention.

Frequently Asked Questions
What are the CDC sleep duration recommendations by age?
Adults aged 18–60: >=7 hours per night; Adults aged 61–64: 7–9 hours per night; Adults aged 65 and older: 7–8 hours per night.
What is sleep debt and can you 'catch up' on weekends?
Sleep debt is the cumulative difference between the sleep your body biologically requires and what you actually obtain. Research shows irregular weekend binge sleeping disrupts circadian rhythms and fails to reverse insulin resistance caused by chronic weekday sleep deprivation.
How does sleep deprivation impede fat loss and muscle gain?
Sleeping less than 7 hours raises evening cortisol by up to 37%, suppresses human growth hormone (HGH) secretion, and disrupts appetite hormones—increasing ghrelin (hunger) by 15% and decreasing leptin (fullness) by 15.5%.
