In preparation for GREENxEXPO, an international horticultural exposition to be held in Yokohama in FY2027, activities were developed with the goal of proposing a behavioral change model to reduce the risk of heat stroke in a hot environment. In FY2024, with the cooperation of the Public Works Office of the Kohoku Ward Office, we visualized and analyzed the risk of heat stroke during work for employees doing civil engineering work outdoors in the hot sun, and constructed a hypothesis for risk reduction.
Of the nine employees who worked throughout the day on a sunny day in early September, we obtained heart rate and location data for three employees of different ages, as well as environmental data such as temperature, humidity, and ground surface temperature. As a result, it was confirmed from the increase in heart rate data that the workload of "Collaborative projects with the City of Yokohama Kohoku Ward" was particularly heavy in an environment where the ground surface temperature increased, and at the same time, it was confirmed that a reduction in the load could be achieved by taking breaks at appropriate times.
