Japan tests AI technology to prevent heatstroke in elderly

Japan’s Environment Ministry has launched a demonstration experiment using artificial intelligence and sensors to protect elderly citizens from heatstroke. The initiative aims to proactively identify risks, as extreme heat has caused many elderly deaths indoors. In 2024, elderly individuals accounted for approximately 85% of heatstroke fatalities, with most occurring at home.

The pilot project includes three primary programs: an AI-based system that estimates core body temperatures and alerts users via smartwatches, a monitoring system that notifies family members through an app when indoor temperatures reach certain levels, and a system that automatically activates air conditioners based on room temperature. The trial, which began in June with approximately 70 participants aged 65 and older, is scheduled to run through September.

Researchers will evaluate the technology’s effectiveness in encouraging preventive actions and assess psychological resistance to new technology among seniors. If successful, the ministry plans to support widespread adoption starting in fiscal 2027. The project seeks to address challenges posed by an increasing number of elderly people living alone and a shortage of caregivers.
