Survey Overview Kracie Pharmaceuticals conducted a survey on heatstroke prevention involving 400 working men and women aged 30-60 across Japan.

Background On April 17, 2026, the Japan Meteorological Agency defined days with temperatures reaching 40°C or higher as "Extreme Heat Days." It has been one year since the implementation of mandatory heatstroke prevention measures under the Industrial Safety and Health Act in June 2025, and the importance of these measures is growing. Casualties from workplace heatstroke in 2025 increased by approximately 40% compared to the previous year.

Key Findings 1. **Awareness**: 62.8% of respondents were aware of the mandatory heatstroke prevention regulations. Among them, nearly half (49.8%) reported a change in their awareness. 2. **Current Practices**: 85.2% of workers implement some form of prevention, with "frequent hydration" (71.0%) and "salt/mineral intake" (43.5%) being the most common. 3. **Challenges**: Workers pointed out the limitations of these measures amidst extreme heat, environmental constraints such as the inability to hydrate during work, and physical challenges including sleep deprivation and appetite loss caused by the summer heat.

Recommendation In addition to basic measures, integrated health management from a Kampo (herbal medicine) perspective is suggested to help workers survive the extreme heat.
