睡眠と心身の健康

This paper reviews some of the representative epidemiological evidence for the relationship between sleep and physical and mental health. Sleep has elements of quantity (sleep duration), quality, and rhythm, and the evidence is summarized by focusing on abnormalities of each element. Regarding sleep duration, we present the results of a systematic review and meta-analysis of short sleep duration and health outcomes. Similarly, the results of a study on longer sleep duration and health outcomes are also presented. Regarding abnormalities in sleep rhythms, a systematic review and meta-analysis of systematic reviews and meta-analyses conducted on shift work and various health outcomes are reviewed to examine the evidence. The relationship between sleep and mental health is discussed in terms of the relationship between sleep and depression in previous epidemiological studies. Based on the findings from these observational epidemiological studies, future research is expected to be based on sleep hygiene education and intervention studies aimed at improving health by improving sleep.
