Outline of Final Research Achievements

The purpose of this study is to examine the influence of bright light via ear cannal on stress and sleeping in nurses with night-shift work and to examine whether or not attention is improved by essential oils . Twenty nurses were divided into groups with ear canal irradiation in the morning, groups in the evening group for 4 weeks, and groups not doing anything. Attention was measured using the Psychomotor Vigilance Task (PVT), and as the subjective evaluation the Athens Sleep Rating Scale, POMS 2 to evaluate mood / emotion was used.

By inhaling the fragrance of peppermint the reaction time of PVT was significantly shortened accompanied with subjective sensation. This reslt indicates that attention must improve by inhaling by peppermint oil.
