Abstract
The purpose of this study is to investigate how the aged persons adapt themselves to the living environment and the environmental temperature. A survey of questionnaire on the daily living action and the residential thermal adaptation have been conducted on about 3, 000 aged persons, living in various regions, in summer and winter time.
The results are as follows :
(1) The structure of body has become smaller and thinner with aging.
(2) There have been high correlations between aging and actions involved in the physiological factors. The amount of sleeping time has become longer and the frequency to go to stool, during sleeping, has increased with aging.
(3) A significant regional difference has been recognized in the frequency of bathing. Groups of aged persons at high latitude, who take fewer bathes, spend longer time for one bathing than groups at lower latitude.
(4) A seasonal difference has been remarked in the amount of sleeping time, that has become longer in winter time because of the delay of the hour of rising.
