Japan built a 'human refrigerator' that cools your body in just 5 minutes

As record-breaking heatwaves become more frequent around the world, keeping outdoor workers safe has become an increasingly urgent challenge. Japan may have come up with an unusual solution. A Japanese company has developed what many are calling a "human refrigerator", a walk-in cooling booth designed to lower body temperature within minutes. Instead of cooling an entire room, the compact cabin focuses chilled air on key parts of the body to provide rapid relief from heat. The innovation is aimed at construction workers, factory employees and others who spend long hours in extreme temperatures, where heat stress and heatstroke remain serious occupational risks.What is Japan’s 'human refrigerator'?The device, officially known as the Do Reimon Box, has been developed by Japanese industrial supplier TRUSCO Nakayama Corporation.
