    The BPS-J had sufficient validity and reliability. Further, eliminating Item 2 from the original version of the BPS strengthened the ability to survey Japanese daytime workers

  • Treatment strategy for insomnia disorder

    Open Access•Yoshikazu Takaesu, Hitoshi Sakurai et al.•ARTICLE•Frontiers in Psychiatry•2023

  • Transdiagnostic association between subjective insomnia and depressive symptoms in major psychiatric disorders

    Open Access•Suguru Nakajima, Yoshiyuki Kaneko et al.•ARTICLE•Frontiers in Psychiatry•2023

    In psychiatric disorders, comorbid depressive symptoms are associated with clinically important issues such as reduced quality of life, a poor prognosis, and increased suicide risk. Previous studies have found a close relationship between insomnia and depressive symptoms in major depressive disorder (MDD), and that actively improving insomnia heightens the improvement of depressive symptoms. This study aimed to investigate whether the association…

  • The effect of nonrestorative sleep on incident hypertension 1–2 years later among middle-aged Hispanics/Latinos

    Open Access•Kaori Saitoh, Takuya Yoshiike et al.•ARTICLE•BMC Public Health•2023

    The present findings suggest the importance of focusing on NRS to help prevent the development of hypertension in middle-aged adults

  • Periocular Skin Warming Promotes Sleep Onset Through Heat Dissipation From Distal Skin in Patients With Insomnia Disorder

    Open Access•Tomohisa Ichiba, Aoi Kawamura et al.•ARTICLE•Frontiers in Psychiatry•2022

    These results suggest that periocular skin warming promotes sleep initiation by enhancing heat dissipation from the distal skin regions in individuals with sleep difficulty and insomnia disorder. Periocular skin warming could thus be a novel non-pharmacological therapy for insomnia disorder
