Abstract :
Emerging evidence suggests that thermoregulatory mechanisms, particularly sweat-mediated sodium excretion,
play a critical role in modulating blood pressure among salt-sensitive individuals. This paper proposes a novel hypothesis:
that migration from hot to cooler climates may inadvertently elevate hypertension risk in salt-sensitive populations due to
reduced sweat output and consequent sodium retention. Drawing on physiological, behavioural, and epidemiological
insights, we explore how climate-driven changes in sodium metabolism intersect with ethnicity, dietary patterns, and public
health screening protocols. The hypothesis is situated within a broader framework of migration health equity, highlighting
the need for culturally and environmentally responsive interventions. We argue for the integration of climate-adjusted risk
modelling into NHS screening strategies and propose targeted behavioural insight trials to assess the impact of
thermoregulatory shifts on cardiovascular outcomes. This systems-level perspective reframes hypertension not merely as a
clinical condition, but as a governance challenge shaped by climate, culture, and physiology.
