Abstract :
Building on prior conceptual work linking migration from hot to cooler climates with increased sodium retention
and hypertension risk (Somersall-Weekes, 2025), this paper proposes a novel technological framework for empirical
validation: a multimodal wearable patch capable of measuring sweat sodium concentration, sweat rate, skin temperature,
ambient temperature, and heart rate. Recent physiological research demonstrates that sweat sodium concentration varies
significantly with environmental temperature, heat acclimatisation, and individual characteristics (Baker et al., 2022),
reinforcing the need for climate-aware biosensing. The proposed device, termed the Thermoregulatory Sodium Assessment
Patch (ThermaPatch), integrates thermoregulatory and autonomic cardiovascular biomarkers to generate climate-adjusted
hypertension risk insights. This paper outlines the physiological rationale, biosensing architecture, data-integration model,
and public health implications. By combining climate physiology, sodium metabolism, and heart-rate monitoring, the
framework advances a new direction in equitable hypertension prevention for migrant and multi-ethnic populations.
