[Abstract]

　Temperature control using air conditioners(AC) at home and office was studied in a rural area a new flats area and an old town near Naha city. People in high flats suffered from poor wind intake with symptoms related to AC. In office the actual temperature was lower than the comfortable level, the latter was similar to that at home. Patients of hypertension and ECG abnormality had a lower temperature in the office. Nutritional data from 19 prefectures of the national survey were combined with the local temperature. The temperature had significant negative relationships with the total calorie, protein, lipid, and carbohydrate intakes in rural area during 1982-1986, which disappeared in 1987-1990. Analyses of the total death, and the death from traffic accidents(TA) were done using temperature on the day of death. The total death rate in the maximum temperature levels divided in six decreased commonly during 1980-1984 but increased during 1986-1990 The death rate from TA had relations with the monthly mean temperature only in winter(positive) and summer(negative). n winter and summer the mean, daily temperature of TA (percentile of cumulative death frequency) was low during 1980-1984, however became high during 1985-1989.
