Japanese Portable Fridge Fights Heatwaves
A Japanese company has developed a device called the "Do Hiemon Box," which resembles a "human refrigerator," aiming to rapidly cool the body and reduce the risk of heat stress during intense heatwaves. The device is about the size of a vending machine and is mounted on areas such as the head, neck, shoulders, and back. It works by lowering the body's internal temperature to 15°C (59°F), while blowing cool air at 5°C (41°F). Users can experience a noticeable reduction in body heat within 5 minutes, and spending 10 minutes inside helps alleviate symptoms of heat stress. The device features three control levels and automatically turns off after 20 minutes to prevent overcooling. It consumes roughly half the energy of a traditional air conditioner. The device was launched for sale in April at a price of approximately $9,230 and is targeted at institutions and companies. This development comes in the context of increasing heatwaves in Japan, with Tokyo recording 48 hospitalizations due to heatstroke in a single day in July.
