CSRPreventing heat disorders

Otsuka Pharmaceutical has been actively working to help the public understand and prevent heat disorders by developing educational tools and sending employees to venues around the country to talk about the issue.

Since POCARI SWEAT was first introduced, Otsuka has advocated the importance of hydration at a wide variety of events and venues. The public has become more aware of the issue since the Study Group for Prevention of Heat Disorders in Sports Activities was established by the Japan Sports Association in 1991, and Otsuka Pharmaceutical began to take part in activities to help prevent heat disorders.
The company has since expanded its activities in this area. Employees are focused on disseminating information, meeting with groups outside of the office to talk about children's sports, safety and health in the workplace, and the importance to senior citizens of staying hydrated.
The ‘Health and Illness’ section of this website contains information on preventing heat disorders, the contents of which are based on the “Guidebook for Prevention of Heat Disorders in Sports Activities” published by the Japan Sports Association. Animated movies within that section explain heat disorders and their prevention in a way that is easy to understand.
In 2012, Otsuka Pharmaceutical launched another heat disorders-prevention initiative, helping to set up the Heat Disorders Prevention website, in cooperation with weather forecasters. The website provides the latest heat indices and up-to-the-minute comments from weather forecasters for specific locations around Japan.

JASA has been engaged in heat disorders prevention initiatives for more than 20 years, and in that time it has reached a wide audience with its message. At the same time, Japan has experienced a number of heat waves in the last few years leading to deaths from heat disorders. Heat disorders can be prevented by taking suitable precautions. Sports legislation in Japan mandates that sports be carried out in a safe manner, and JASA will continue working to prevent heat disorders in an effort to contribute to safe sports.

Comparing the ten years before and after 1995, the death rate from heat disorders in a variety of places — the home, at school, in industry — we see there was an increase. By contrast, the death rate from heat disorders at sports facilities, which in the past had been the highest, has fallen by two-thirds.*1 The ratio of heat disorders victims 19 years old or younger has also fallen. *2 The “Five Articles for Prevention of Heat Disorders in Sports Activities” issued by the Japan Sports Association, as well as the various activities and lectures to publicize this information, have clearly had a positive impact.
