What it is

Biometric wearables — rings, bands and watches — continuously measure heart rate, heart-rate variability (HRV), skin temperature, sleep stages and activity, converting raw physiological signals into daily readiness and recovery scores.

Its role in longevity

Two of the metrics these devices track — HRV and sleep — are independently associated with mortality and resilience. Continuous feedback lets users see how behaviour, training and recovery affect their physiology and adjust before problems become clinical.

The research

Peer-reviewed studies on the active compound — citations link to PubMed.

“Previous studies have shown a positive correlation between heart rate variability and clinical outcomes, including all-cause mortality.”
Annals of Noninvasive Electrocardiology 2024 · PMID 38288511
“Both short and long sleep duration were associated with an increased risk of all-cause mortality in this meta-analysis.”
Epidemiology and Psychiatric Sciences 2018 · PMID 30058510
“lower heart rate variability was associated with a higher risk of all-cause death and cardiovascular events”
Biol Res Nurs 2019 · PMID 31558032
