Introduction

On July 6, 2025, Wellness Design LLC, headquartered in Chiyoda, Tokyo, officially launched its latest innovation: the health management app 'Mizutama Sun'. The application is designed to support the prevention of heat-related illnesses, such as heat stroke and dehydration. By incorporating environmental information like the Wet Bulb Globe Temperature (WBGT) along with individual user characteristics such as health status, constitution, and lifestyle habits, Mizutama Sun offers a sophisticated visualization of health risks. Utilizing a unique AI algorithm, this app sets itself apart in the preventative healthcare community.

Background and Development

In recent years, heat-related illnesses and dehydration have become significant public health concerns. Despite this, traditional methods of monitoring risk often depend solely on environmental factors like temperature and humidity, which may not correlate with individual physiological differences or lifestyle habits. Mizutama Sun addresses this gap by focusing on the personal risk level for each user. By analyzing factors including age, trends in measured values, and lifestyle patterns, users can receive a tailored and reliable preventative strategy. The app also analyzes situations where risks may heighten and visualizes warning signs or patterns specific to each user, effectively serving as both a preventative tool and a means for personal insight and future action planning.
