Executive Diagnosis
This comprehensive audit confirms a specific phenotype: The "Physiological Elite" with "Behavioral Chaos".
- The Hardware (Body): Your sleep efficiency (92%), deep sleep drive (49%), and cardiac recovery (20% dip) are in the top 1% of the population. Your body knows exactly how to repair itself.
- The Software (Schedule): Your circadian rhythm is under constant attack. Social Jetlag (shifting sleep times on weekends) is acting as a metabolic stressor.
- The Glitch (Airway): Persistent hypoxic dips (SpO2 < 90%) and Apnea clusters indicate a mechanical airway issue that needs clinical attention.
Chapter 1: Duration
The "Bell Curve" of Your Nights
Duration Histogram
Frequency of sleep duration buckets.
Consistency matters more than total hours. Sleeping 6 hours consistently is often metabolically healthier than yo-yoing between 4 and 10 hours.
Chapter 2: Longitudinal Stability
The "Yo-Yo" Effect over 365 Days
Daily vs. 30-Day Moving Average
Chapter 3: Architecture

The Quality Matrix
Duration vs. Efficiency Scatter
Chapter 4: Deep Sleep
Your Physiological Superpower
You vs. The World
You average 49% Deep Sleep. The average adult gets 15-20%. Elite athletes aim for 25%. You are in a league of your own.

Chapter 5: Fragmentation
Wake Events & Disruptions
Fragmentation Index: Low.
You rarely wake up once asleep. Most nights show 0-1 "Session" interruptions. This continuity is critical for completing full REM cycles (neuro-restoration).
Chapter 6: Sleep Onset
The "Race to Unconsciousness"
Latency Distribution
Falling asleep in < 5 minutes isn't "good"—it's a sign of pathological sleepiness. A healthy, rested brain takes 10-20 minutes to transition from Alpha waves to Theta waves.
Chapter 7: Social Jetlag
Living in Two Time Zones
Bedtime Roulette (Scatter Plot)
Each dot is a night. Notice the vertical spread on Fridays and Saturdays.
Chapter 8: The "Monday Blues"
Why the Week Starts Hard
Weekly Radar Analysis
Saturday Peak
You sleep longest on Saturdays, trying to repay the week's debt.
Monday Crash
Your HRV is lowest on Monday nights. This is your body reacting to the "Jetlag" of shifting your schedule back to work mode.
Chapter 9: Cardiovascular Load
The Heart's Night Shift
Waking vs. Sleeping BPM
Chapter 10: Autonomic Recovery
Heart Rate Variability (HRV)

BPM vs Deep Sleep Correlation
Chapter 11: Oxygenation
The Hypoxic Burden
SpO2 Minimums
Chapter 12: Apnea Screening
The "Invisible" Interruptions
Respiratory Combo Chart (Risk Overlay)
Screening Result: POSITIVE
125 nights > 5 events/hr.
This is highly suggestive of mild-to-moderate OSA. The correlation with SpO2 drops confirms airway resistance.
