Innovative Cooling Solutions for Workers

In response to escalating instances of heat stroke, Japan Sigmax, a company rooted in the development of daily support products under the MEDIAID brand, is taking significant steps to bolster safety for workers in high-temperature environments. Beginning in April and continuing through July 2026, the company will showcase its groundbreaking Peltier water-cooled cooling vest, the "MEDIAID Icing Gear Best 2," at six upcoming exhibitions.

Rising Concerns Over Heat Stroke Cases

The urgency for effective heat stroke countermeasures has never been more pressing. A stark increase in emergency dispatches due to heat stroke has led to legislative changes reinforcing safety requirements in workplaces. As of June 2025, companies are mandated to comply with the revised Labor Safety and Health Regulations that implement penalties for non-compliance. Additionally, by March 2026, the Ministry of Health, Labour and Welfare is set to enforce guidelines for all workplaces to prevent heat-related illnesses.

Tragically, the year 2025 recorded the highest number of heat stroke-related injuries, with 1,681 cases requiring four or more days away from work, including fatalities. The manufacturing and construction sectors are particularly affected, exhibiting the most significant numbers in such cases due to operating under extreme heat conditions.

The Mediaaid Icing Gear Best 2

Addressing these pressing issues, Japan Sigmax has leveraged its extensive experience in the medical field to develop the "MEDIAID Icing Gear Best 2," which utilizes a combination of Peltier elements for cooling and water circulation. This innovative vest can maintain a cool temperature in environments exceeding 35°C for up to five hours. Since its launch in 2025, this cooling gear has received widespread acclaim in various labor environments and is a critical component in the fight against workplace heat stress.

Exhibition Plans

Last year’s exhibition received positive feedback, and the company plans to increase its presence this year with six scheduled appearances to demonstrate the cooling vest's effectiveness firsthand. Attendees can expect to experience the cooling technology in action, try on the vest, learn about best practices, and explore rental options.
