The purpose of this study was to evaluate the factors affecting sleep quality in winter and summer among the Japanese elderly, living with short daylight hours in winter. Overall, 149 participants who had joined the Citizen's College for the Elderly in Kyotango-city (Kyoto, Japan) were compared based on questionnaires filled by them in winter and summer. Sleep quality was assessed using the Pittsburgh Sleep Quality Index, and mood and daily activities were assessed by the "Profile of Mood Scale". The sleep duration in summer was significantly shorter than that in winter; the subjects had more sleep difficulties and significantly higher scores for "vigor" and "fatigue" in summer than that in winter. The proportion of participants who talked daily with someone was significantly lower in winter than that in summer. Multiple regression analysis revealed that their sleep quality in winter was related to factors such as "frequency of going out", "fatigue", and "mental disorders" and, in summer were "tension-anxiety" and "digestion disorders". The subjects lived in a snowfall zone; however, "daily going out in the winter" was suggested as one of the practical indicators leading to better sleep quality. Therefore, the appropriate nursing guidance for better sleep quality may vary between winter and summer.
