TL;DR
A Japanese company has created a large, human-sized refrigerator called the Do Hiemon Box to help prevent heat-related illnesses, mainly for outdoor and industrial settings. The device cools users to 15°C and targets key heat zones, but is currently only available for commercial use and costs around $10,000.
A Japanese company has introduced the Do Hiemon Box, a human-sized refrigerator designed to cool individuals directly, aiming to prevent heat-related illnesses during extreme heat conditions. The device is primarily targeted at outdoor workers and industrial sites, offering rapid cooling in a compact, vending machine-like form. This innovation highlights the increasing need for effective cooling solutions amid rising global temperatures and heatwaves.
The Do Hiemon Box is a large, human-sized cooling unit that maintains an interior temperature of 15°C from the moment a person enters. It features targeted airflow at 5°C directed at key heat-dissipation zones such as the head, neck, shoulders, and back, which are critical for body temperature regulation. The device automatically shuts off after 20 minutes to prevent overcooling and ensure safety, making it a quick-response tool for heat stress prevention.
Currently, the device is not available for personal purchase. It is marketed mainly for commercial use in environments like construction sites, factories, warehouses, and outdoor festivals. The cost is approximately $10,000 US per unit, making it a significant investment for most consumers. The technology underscores the growing concern over heat-related health risks as global temperatures rise.
Implications for Workplace Safety in Hot Climates
The Do Hiemon Box represents a novel approach to combatting heat stress, which is increasingly relevant as climate change causes more frequent and severe heatwaves. By providing immediate, targeted cooling for outdoor workers, it could reduce incidents of heat exhaustion and heatstroke, potentially saving lives and reducing healthcare costs. Its development signals a shift toward innovative, technology-driven solutions for climate-related health challenges, though its high cost limits immediate widespread adoption.

Rising Temperatures Drive Innovation in Cooling Technologies
Japan has experienced several days over 40°C (104°F), termed ‘Cruelly Hot Days,’ prompting increased efforts to protect vulnerable populations such as outdoor workers. Traditional cooling methods like fans and air conditioning are often impractical or unavailable in outdoor or industrial settings. The Do Hiemon Box is part of a broader trend of developing specialized cooling devices to address heat-related health risks amid climate change. Prior efforts have focused on portable fans and cooling vests, but this device offers a more direct and rapid cooling method.
“The Do Hiemon Box provides an immediate cooling solution that targets the body’s heat dissipation zones, which could significantly reduce heat-related health incidents.”

Unclear Long-Term Adoption and Cost-Effectiveness
It is not yet clear whether the Do Hiemon Box will become widely adopted outside of industrial and commercial settings. The high price point of around $10,000 per unit may limit accessibility for smaller businesses or individual consumers. Additionally, long-term durability, user comfort, and potential health risks associated with repeated use are still under assessment. Further testing and pilot programs are needed to evaluate its effectiveness and practicality in diverse environments.
Future Deployment and Potential for Consumer Versions
Manufacturers are expected to conduct pilot programs in various outdoor work environments to assess the device’s real-world performance. If successful, there may be efforts to reduce costs and develop smaller, more affordable versions for broader use, including possible consumer applications. Regulatory approval and safety testing will also influence how quickly the device can be integrated into standard safety protocols for outdoor workers.
Key Questions
Can I buy a Do Hiemon Box for personal use?
Currently, the Do Hiemon Box is only available for commercial use and costs around $10,000. Personal purchase options are not yet available.
How does the Do Hiemon Box work?
The device maintains an interior temperature of 15°C and directs targeted airflow at key heat-dissipation zones for rapid cooling. It automatically shuts off after 20 minutes for safety.
Initial testing suggests it can rapidly cool users and reduce heat stress, but extensive field studies are still underway to confirm its long-term effectiveness.
What environments is the Do Hiemon Box designed for?
It is mainly intended for outdoor work sites like construction, factories, warehouses, and outdoor festivals where heat exposure is a concern.
Will the device become more affordable in the future?
It is uncertain. Cost reduction may occur if the technology is mass-produced or adapted for consumer markets, but no official plans have been announced.
