■ Background of MEDIAID Heatstroke Prevention Item Relaunch

In recent years, heatstroke in the workplace has become increasingly serious. The number of casualties requiring four or more days of leave from January 1 to December 31, 2025, was 1,681 (preliminary figures as of the end of December 2025), a significant increase of 40.6% compared to the same period last year (*1). The Ministry of Health, Labour and Welfare is also urging all business sites to thoroughly implement heatstroke prevention measures (*2).

Furthermore, from June 1, 2025, due to the revision of the Ordinance on Industrial Safety and Health, heatstroke countermeasures will become mandatory with penalties, making corporate heatstroke measures an urgent issue.

However, according to a survey of the construction industry (n=1,080) announced by the Ministry of Health, Labour and Welfare, two out of three people at sites where heatstroke occurred were wearing 'clothing with a body cooling function'. Since most of these were fan-equipped work clothes (*3), it is suggested that heatstroke measures not adapted to environments such as high temperature and humidity may not lead to sufficient effects.
