Japan Unveils 'Human Fridge' to Beat Extreme Heat

As record-breaking heat continues to grip Japan, a refrigeration company has introduced an innovative cooling device dubbed the "Human Fridge" to help people recover quickly from extreme temperatures.

Developed by SDRS, the machine, officially named the Do Hiemon Box, is designed primarily for construction workers, factory employees, and others who spend long hours outdoors. Resembling a typical Japanese vending machine, the booth allows one person at a time to step inside and cool down.

The unit maintains an internal temperature of around 15°C (59°F). Once inside, cool air is directed toward the user's head, neck, shoulders, and back. According to the company, the system can help the body feel noticeably cooler within five minutes, potentially reducing the early effects of heat exhaustion. However, it is not intended to replace medical treatment in cases of severe heat-related illness.

The Human Fridge is being distributed through industrial equipment supplier Trusco Nakayama. A public unit has also been installed at Maebashi City Hall in Gunma Prefecture, where visitors can use it free of charge during office hours.

With temperatures in parts of Japan approaching 38°C and heatstroke cases on the rise, authorities and businesses are exploring new ways to protect people from extreme weather.

Priced at around $9,326 (approximately ₹8 lakh), the Do Hiemon Box is currently aimed at workplaces and public institutions rather than home use. Experts believe that as climate change drives more frequent heatwaves, demand for personal cooling technologies like this could continue to grow.
