Association between daily long working hours and actigraphic sleep, vigilance, blood pressure and psychological responses: a 10-day observational study among Japanese daytime workers.

ABSTRACT:

Objectives

This study examined the association between daily long working hours (LWHs) and diverse health-related outcomes, using objective and subjective measures. It further evaluated the specific durations of daily LWHs that may be considered inappropriate in cases with adverse health effects.

Methods

98 employees participated in a 10-day observational study. Participants self-reported their daily working hours, subjective states and performed the measurement of blood pressure (BP) and psychomotor vigilance test (PVT) immediately on waking and before bedtime. Objective sleep was recorded nightly using actigraphy. Linear mixed model (LMM) analysis was performed.

Results

LWHs were significantly associated with higher systolic BP (β=0.65), greater fatigue (β=1.79) bef
