Japan Introduces ‘Human Refrigerator’ to Beat Summer Heat

Japan has announced a new wearable cooling system called the “human refrigerator.” The device is designed to lower body temperature during heat waves. It uses a combination of liquid circulation and thermoelectric elements. Engineers claim it can reduce core temperature by several degrees. The product targets outdoor workers and vulnerable populations. Officials say it could help mitigate health risks from rising temperatures. The prototype will be tested in several prefectures this summer. Success could lead to wider commercial rollout and influence future cooling tech.
