THE EFFECT OF HEAT AND SOLAR RADIATION ON THE WATER–ELECTROLYTE BALANCE OF ROAD PATROL SERVICE OFFICERS

Abstract

This analytical article examines the mechanisms of water–electrolyte imbalance among road-patrol service (RPS) officers working outdoors under conditions of high ambient temperature and intense solar radiation. The study is based on international scientific publications from 2020–2024, data from global health and occupational safety organizations, and meta-analyses of observational studies involving 118–160 personnel working in hot climate conditions. According to the findings, officers who remain under 35–40°C temperatures for more than 4 hours lose an average of 1.1–1.4 L of fluid per hour, while plasma sodium levels decrease by 2.7–4.1% and potassium levels drop by 0.2–0.4 mmol/L. The Heat Stress Index (HSI) has reached hazardous levels in many regions. The study underscores the necessity of developing specialized rehydration protocols for RPS officers.
