Nationwide "Bathing for Heat Acclimation" Campaign Launches in Japan for Early Heatstroke Prevention
To prepare for a long, hot summer, the Heatstroke Prevention Call Project Secretariat (Japan Design association) launched the "Bathing for Heat Acclimation Action" nationwide in May as an easy-to-implement early countermeasure against heatstroke. This public-private initiative promotes bathing as an alternative method for heat acclimation, which can be difficult to achieve through sustained exercise. The campaign has launched a dedicated website with advice from medical experts and is expanding its reach through collaboration with 92 municipalities and corporate sponsor Kao Corporation, distributing awareness posters and bath additives.

The Heatstroke Prevention Call Project Secretariat (operated by the general incorporated association Japan Design, located in Shibuya, Tokyo; Secretary General/Social Entrepreneur: Taro Yamashita) has announced the full-scale, nationwide launch of the "Bathing for Heat Acclimation Action," a public-private partnership initiative designed as an accessible, early countermeasure for the anticipated hot summer.
Heat acclimation before the peak of summer is widely recognized as a crucial measure against heatstroke. However, a significant challenge has been that many people find it difficult to consistently perform the recommended light exercises or stretches for the necessary two-week period.
In response, the project has focused on bathing as a more accessible method. Since May, it has been promoting the "Bathing for Heat Acclimation Action" in collaboration with municipalities, companies, private organizations, and the general public across Japan.
A dedicated website for the campaign offers advice from Dr. Yasufumi Miyake, an emergency medicine physician and heatstroke specialist, and Dr. Shinya Hayasaka, a balneotherapy specialist and bathing expert. Furthermore, the initiative is supported by Kao Corporation, which provides fundamental bathing knowledge through its "Healthcare Navi" website, helping users deepen their understanding and easily practice heat acclimation through bathing.
The campaign has already garnered participation from 92 municipalities across 35 prefectures. At local seminars and events, dedicated posters are displayed, and Kao's carbonated bath additive, "Bub," is distributed free of charge.
Moving forward, the project secretariat will continue to support participating municipalities and organizations by providing posters and other materials. The goal is to establish the "Bathing for Heat Acclimation Action" as a nationwide preventative measure to reduce the number of heatstroke victims.
The awareness posters are available for anyone to download from the campaign website. The secretariat is encouraging the public to start practicing "Bathing for Heat Acclimation" now to prepare for the long, hot summer ahead.
