Tools & Wearables

Apple Watch

Smartwatch with growing list of health features: ECG, blood-oxygen, AFib screening, fall detection, sleep tracking, fitness. Strongest health-tech ecosystem on the platform side.

Carotid Ultrasound

Non-invasive imaging of the carotid arteries — measures intima-media thickness (cIMT) and detects plaque, providing a direct assessment of atherosclerotic burden and stroke risk.

Continuous / Ambulatory Blood-Pressure Monitor

24-hour ambulatory or wearable continuous BP measurement — captures diurnal variation, nocturnal dipping, and out-of-clinic BP that stratifies risk far better than a single clinic reading.

Continuous Glucose Monitors (Stelo, Libre, Dexcom)

Wearable interstitial-glucose sensors that report values every 1–5 minutes for 10–14 days per sensor. FDA-cleared OTC consumer devices arrived in 2024.

Eight Sleep

Mattress topper that heats and cools dynamically through the night to optimise sleep-stage progression. Premium price; supportive small-RCT data on sleep efficiency.

Garmin Watches

GPS sports watches with strong endurance-athlete pedigree. Forerunner, Fenix, and Venu lines offer comprehensive training metrics, no subscription, and long battery life.

Grip Dynamometer

Hand-held device measuring maximal grip strength — one of the strongest single-metric mortality predictors in older adults, and a cheap, portable clinical tool.

Home Blood-Pressure Cuff

Validated upper-arm BP cuff. Among the highest-value single longevity tools — home BP measurement is more reliable than office BP and guides one of the most-evidence-backed risk reductions.

Oura Ring

Finger-worn ring tracking sleep stages, HRV, resting heart rate, body temperature, and activity. Best-in-class consumer sleep tracking with strong agreement to polysomnography for some metrics.

Portable / Wearable ECG

Smartphone-attached and watch-based single-lead ECGs enable at-home rhythm detection, especially of paroxysmal atrial fibrillation — a common, under-detected, high-consequence age-related arrhythmia.

Red Light Panels

Home photobiomodulation panels delivering red (~660 nm) and near-infrared (~850 nm) light. Marketed for skin, recovery, and cognitive uses; evidence is mixed and dose-dependent.

Retinal Imaging

Digital fundus photography and OCT — enable direct visualisation of the microvasculature and CNS in a non-invasive scan; increasingly recognised as an aging-biomarker platform.

Sauna Blankets (Infrared)

Portable infrared blankets marketed as at-home sauna substitutes. Less heat exposure than traditional dry-sauna sessions; convenience comes at the cost of intensity.

Smart Scales (BIA Body Composition)

Bioelectrical-impedance-analysis scales report body-fat percent, muscle mass, water — useful for trend tracking but unreliable for absolute values vs DEXA.

WHOOP

Subscription-based wrist strap focused on recovery, strain, and sleep tracking for athletes. Strong on continuous HRV trend tracking and strain-based load management.
