The Relation Between Environmental Conditions and the Occurrence of Exertional Heat Disorders During Physical Activity

Abstract

Deaths and morbidity due to heat disorders during physical activity were gleaned from newspaper reports between 1970 and 1990. The environmental temperatures (dry-bulb temperature and relative humidity) recorded at the closest meteorological observatory at the time of occurrence were used to calculate the wet-bulb temperature and WBGT (wet-bulb globe temperature), and the relationship between heat disorders and environmental temperature was analyzed. © 1992, The Japanese Society of Physical Fitness and Sports Medicine.
