The purpose of this study was to examine the effects of two 15-min naps on nurses who work at night in a three-shift system. Of the 15 nurses who were included as study subjects on a night shift, eight took two short naps (the Nap condition), and seven worked without taking a nap (the No-nap condition) during the night shift. We measured sublingual temperature and the bispectral index (BIS), obtained heart rate and heart rate variability measures from an electrocardiogram (ECG), and evaluated sleepiness and fatigue levels every hour using the Visual Analog Scale (VAS). Both subjective sleepiness and fatigue increased between 4:00 and 5:00, with no significant differences observed between the two groups. However, the low- to high-frequency ratio (LF/HF) in the Nap condition group was found to be significantly lower than in the No-nap condition group. Furthermore, a sudden, brief increase in HF values was observed in the No-nap condition group in the morning. The results of this study suggest that taking two short naps may effectively reduce tension and prevent a brief increase in HF values by suppressing sympathetic nervous activity in the morning.

脳血管疾患は,我が国の死因の首位を昭和56年より悪性新生物に譲ったとは言え,依然第2位を占めている疾患である。幸いにして救命し得た場合でも,後遺症の1つである片麻痺は患者が社会復帰する上で大きな問題となっている。特に利き手側に片麻痺が生じた場合には,日常生活動作上の支障をきたし,利き手変換を余儀なくされることが多い。そこで,今回,我々は,日常生活動作の中でも重要と思われる食事動作と,コミュニケーションの大きな要素である書字について,健常者を対象として利き手変換を行ない,筋電図を用いて検討したので,その結果を報告する。
