The Science of Longevity

The gold standard for measuring autonomic nervous system health. Higher HRV correlates with better stress resilience, recovery capacity, and overall longevity.

Measures the percentage of hemoglobin molecules carrying oxygen. Critical for detecting sleep apnea, respiratory issues, and altitude adaptation.

Continuous monitoring reveals circadian rhythm patterns, menstrual cycle phases, early illness onset, and metabolic rate changes.

Measures micro-changes in skin conductance caused by the sympathetic nervous system. Reveals unconscious stress responses and emotional regulation patterns.

A fundamental cardiovascular health marker. Trending downward indicates improving fitness; sudden increases may signal overtraining or illness.

Derived from PPG waveform analysis. Elevated sleeping respiratory rate is an early indicator of respiratory infections and metabolic changes.
