Coastal salt in drinking water linked to higher blood pressure worldwide
TL;DR
A meta-analysis of 27 population studies (over 74,000 participants across multiple countries) finds that higher salinity in drinking water is associated with higher systolic and diastolic blood pressure and about a 26% higher risk of hypertension, especially in coastal populations where seawater contaminates freshwater. While individual increases are modest, the population-level impact could be substantial, highlighting an environmental factor in cardiovascular risk and the need for better drinking-water standards and further research. In the meantime, checking local water quality and managing overall sodium intake are prudent steps.
