Jun 19, 2025 (News On Japan) - On June 18th, Fukuoka Prefecture issued its first heatstroke alert of the year, with 16 people being transported due to suspected heatstroke, according to a summary from FBS. The scorching heat, which already feels like midsummer, has led to the launch of a product showcase aimed at helping people cope with the extreme temperatures.
At around 3 p.m. on June 18th, Fukuoka City recorded its highest temperature of the year, reaching 33°C. Other parts of the region also experienced similarly high temperatures. According to the Japan Meteorological Agency, temperatures in northern Kyushu are expected to be above average over the next three months.
The event, which began in Fukuoka City on June 18th, introduces innovative products designed to beat the intense summer heat. Among the exhibits is a cooling vest that works solely by adding water, no electricity required. The vest uses a phenomenon where liquid evaporation absorbs surrounding heat, lowering temperatures by 5°C to 15°C. Once water is added, the cooling effect can last up to 72 hours, making it particularly useful in disaster-stricken areas where power outages may occur.
In addition to the cooling vest, there are products that monitor changes in the body's condition due to heat. One such device uses AI to analyze facial expressions and provide an assessment of the risk of heat-related illness. By recognizing factors such as sweating and changes in skin color, the AI system can predict health risks several hours in advance. This system was developed by a subsidiary of Pola, the cosmetics giant, in collaboration with a healthcare company, utilizing approximately 20 million facial data samples.
This product has seen growing demand since its release over a year ago, with educational institutions, such as junior high schools in Yonezawa City, Yamagata Prefecture, and Todoroki High School in Setagaya, Tokyo, adopting the technology.
Additionally, another product offers a wearable cooling device for the neck, capable of reducing the temperature by up to 20°C. This product, dubbed a "wearable air conditioner," uses thermoelectric materials to absorb heat when powered by a battery, offering a portable solution to personal cooling. The product has experienced a 20-fold increase in sales compared to last year, as its lightweight and compact design make it easier to use.
By embracing the latest heat-relief innovations, individuals can protect themselves from the dangers of extreme heat.
