Can Wearables Measure Biological Age?
A wearable can produce an age-like estimate without performing a molecular assay.

What the device observes
Wearables record or estimate selected physiological and activity signals. The manufacturer can combine them into a score expressed as an age or pace. WHOOP Healthspan is one example.
Source 1: WHOOPUnderstand the missing layers
A sensor-derived age is not a direct DNA-methylation, glycan or proteomic measurement. Evidence for the input signals and evidence for the combined age output should be considered separately.
Use a trend with context
Check the required wear time, data completeness, eligible membership and update policy. Keep changes in the device or algorithm in mind when interpreting a trend. A more favorable display does not establish that a person has reversed aging.
