Using a wearable (Oura Ring, WHOOP, Garmin) or under-mattress sensor to track sleep stages, HRV, resting heart rate, and sleep efficiency nightly. Sleep trackers reveal hidden patterns — specific foods, alcohol, late exercise, or screen time that are silently destroying sleep quality. Identifying and eliminating even one poor sleep habit through data can transform nightly deep sleep percentage and produce profound downstream effects on skin and hormones.

Oura ring revealed that one glass of wine was destroying my deep sleep. Cutting it added an hour of slow-wave sleep.

Found out late-night eating was crashing my HRV. Fixed it and sleep quality jumped. Data is invaluable.
