Effect of Thermal Stress on Urine Specific Gravity, Blood Pressure, and Heartbeat Among Underground Miners
Abstract: Underground miners
highly exposed to thermal stress hazard. Closed condition, heavy work load, and
limited ventilation are the common cause of high environment temperature in
underground mining. Thermal stress can influence metabolism and physiological
function of human body. The objective of these study is to investigate the
effect of thermal stress to physiological (bodyweight, blood pressure, urine
specific gravity, and heartbeat) of underground miners. This study is
observational cross sectional study with 42 underground miners. Thermal stress
level is 147.14 Wm2 and categorized as unrestricted zone. These study showed
that urine specific gravity, blood pressure, and heart beat on underground
miners were change after shift work, while the body weight changes were not
observed. The relation among TWL with blood pressure, urine specific gravity,
and heartbeat is low category.
