Prevention of heat disorders in the Singapore Armed Forces--1984-1989

A review of the incidence of heat disorders in the Singapore Armed Forces was done in relation to the preventive and corrective measures applied. Data was compiled and analysed from records kept by the SAF Medical Services. A thorough review was made into all the preventive measures carried out thus far and the effectiveness was evaluated. There was a rise in the incidence of heat strokes from eight cases in 1984 to a peak of 46 cases in 1986. Subsequently, aggressive measures were adopted and the incidence fell significantly in 1988 and 1989. The main strategy involved a comprehensive health education programme, regulations, active surveillance and aggressive treatment. However, the incidence has not fallen to the pre-1984 levels. Therefore, a strict vigilance must be constantly maintained to prevent further mortality and morbidity.
