Outline of Final Research Achievements

Previous studies suggested fluctuation of skin temperature as a potential indicator of internal biological rhythm because it shows mirror image of rectal temperature. In the present study, we assessed association between fluctuation of skin temperature and health problems among 590 elder participants in winter. Distal and proximal gradient (DPG) of skin temperature was significantly associated with nocturnal blood pressure decline and prevalence of nocturia. In addition, wrist temperature at evening (2h before bedtime) and initial night (2h after bedtime) was significantly associated with objectively measured sleep onset latency.
