THE EFFECT OF ELECTROLYTE SOLUTION ON URINARY DENSITY AND OSMOLALITY IN WORKERS IN HEAT STRESS ENVIRONMENT

Abstract

Background : Heat exposure in workplace is one of potential hazard that could harmed to workers especially for their urinary tract system. This study examined the effects of electrolyte water solution in laundry worker’s urinary density and osmolality in heat stress environment. Methods : Wet bulb globe temperature, and relative humidity were measured. Seventy workers divided in two groups of thirty five were given isotonic and hypotonic electrolyte solution ad libitum respectively. Fluid intake during working and breaktime were measured. Two samples of urine were taken from each worker at 10 am and 15 pm of working. At the end of study the amount of water consumed were observed.
