Japan Unveils 'Human Refrigerator' To Help Workers Beat Extreme Summer Heat
A Japanese company has launched a specialized one-person cooling station designed to provide immediate relief for workers during severe summer heatwaves. Known as the Do Hiemon Box, the localized booth aims to reduce heatstroke risks for individuals working in high-temperature environments.

Japanese developers have introduced a compact cooling solution called the Do Hiemon Box to address the rising frequency of extreme summer temperatures. This one-person booth functions as a personal recovery station, allowing workers to step inside and rapidly lower their body temperature through controlled air circulation.
The unit is mobile and can be deployed at construction sites, factories, or outdoor events where traditional air conditioning is impractical. By providing a concentrated blast of cold air, the booth helps mitigate the physical toll of humidity and high heat on laborers and service staff.
This innovation comes as Japan tracks record-breaking summer temperatures, prompting businesses to seek new technological methods for employee safety. The device is being marketed as a critical tool for heatstroke prevention in industries that require prolonged physical activity in the sun. Source: Do Hiemon Box
