Abstract
The aspects of skin temperature on the aged is considered from the viewpoint of seasons, daily activities, air conditioning and forth.
The following results were obtained :
1) During the day in summer, the skin temperatures on the aged are lower than that of college students, but at night those of the aged are higher. 2) During the day in winter, the chest temperatures of the aged are lower than those of students. The foot skin temperatures of aged are, however, higher, especially among men. That is because of the use of Kotatu.
3) In winter, the chest skin temperatures of the aged are the same as those recorded in summer, because most of them use electric blankets when sleeping.
4) During ambient temperatures are greater than 27°C, chest skin temperatures of aged women is harder to increase than those of female college students, but when ambient temperatures fall bellow 17°C they go down more.
5) As results of considering the relationship between skin temperature and thermal sensation, it was found that insensitiveness increases by aging, and it is more significant in winter.
