Regional differences in preventive behaviors against heat disorders during COVID-19 infection prevention

Abstract

The questionnaire survey was conducted from June to September 2021 on preventive behaviors against heat disorders under COVID-19 infection prevention. A total of 208 respondents aged 18-29 were divided into three groups which were Hokkaido, Kanto and Kansai region. In the Kanto and Kansai regions, people were more aware of the need to prevent heat stroke in summer than in Hokkaido, and took measures to prevent heat stroke by using body cooling products and air conditioners. Air conditioners and dehumidifiers were also used in houses. In Hokkaido, people were less conscious of preventive behaviors against heat disorders, and air conditioners and dehumidifiers were not widely used in houses. People in Kansai had the highest thermal discomfort due to wearing masks, and used cloth masks slightly more than the other regions. The respondents in Hokkaido were the most positive about removing masks, while those in Kanto were the most negative. These results suggest that regional differences in climate and COVID-19 infection status make a difference in people's awareness of heat disorders and preventive behaviors.
