One of the reasons behind this is said to be the aging of the working population. According to the 2022 survey by the Ministry of Internal Affairs and Communications, the number of workers aged 65 and above reached a record high of 9,120,000. There were 810,000 elderly workers in the construction industry, and 900,000 in the manufacturing industry, approximately 1.7 times and 1.4 times more, respectively, than 10 years ago. With that in mind, in March of 2023 the Ministry of Health, Labour and Welfare strongly urged approximately 500 organizations of construction and manufacturing companies to use the Wet Bulb Globe Temperature (WBGT) that shows the degree of risk for heatstroke, but the number of casualties (fatality and more than 4 days of absence from work) in the workplace caused by heatstroke in the workplace in 2023 was 1,106 (an increase of 279, 34% increase year-on-year), which is still increasing.

Starlite's beliefs

To eliminate the number of casualties caused by heatstroke in the workplace, we believe it is necessary to take individual measures to manage the physical condition of each person, rather than a "one-size-fits-all" approach for everyone, and to take measures according to whether a person is "heat-resistant" or "heat-sensitive". For example, we can further demonstrate the effectiveness of conventional methods such as "drinking water" and "taking a break" by individually visualizing the data trends on heatstroke risk, and taking appropriate measures based on the results of analyzing and detecting the signs of heatstroke.
