Light Sleep vs. Total Sleep (2022) – Bubble Size: Recovery Score

There is a clear linear relationship between time spent asleep and light sleep. With more sleep, the most significant increase among the three sleep types is light sleep.

\n\n

Heart Rate Variability's Effect on Recovery Score

HRV is personal — one person's HRV of 70 signals great recovery while for another it may be low. This is shown by the bimodal lines of correlation in the data.

Daily Strain Distribution by Day of the Week

Strain is relatively even across weekdays with a slight increase on Thursdays and Fridays, and a dip on weekends — consistent with typical rest days.

Recovery Score – September 2023 (Weekends Marked in Red)

Weekend recovery drops significantly — likely due to increased alcohol consumption. The pattern is consistent throughout the month.

Skin Temp vs. Heart Rate Variability (with Trend Line & Anomalies)

Higher skin temperature correlates with lower HRV, leading to lower recovery. Anomalies (points >2 std dev from regression) are highlighted.
