Research on the Occurrences of Heatstroke in School Environment Discussion based on the Occurrences of Heatstroke every Local Area Block of Japan

Abstract

The frequencies and characteristics of heatstroke occurred in Japanese schools were investigated by using the data of NAASH (National Agency for the Advancement of Sports and Health), and analysis was dune for a period of 10 years from 2005 to 2017. According to a nationwide scale, the number of accidents in schools tended to decrease. However, the ratio of heatstroke episode in schools tended to increase. The highest ratio of heat stroke occurred in high schools. The index of “heatstroke rate” was defined as the number of heatstroke occurred at an objective area block of Japan divided by the number of total students in the corresponding objective area block. The heatstroke rates occurred on schoolyard, in gymnasium, and in school building were high in Kyushu, Shikoku, and Chugoku area (hot and humid area). In 2017, the heatstroke rate in school building in Hokkaido area was the highest, although the mean outdoor temperature was the lowest in Hokkaido. In the heatstroke ratio of Hokkaido in gymnasium and school building, many cases occurred at cultural events.
