Daily light exposure profiles and the association with objective sleep quality in patients with Parkinson's disease: The PHASE study.

ABSTRACT:

Study objectives

Light information crucially influences sleep initiation and continuity. The purpose of this study was to compare daily light exposure between patients with Parkinson's disease (PD) and non-PD older adults and evaluate the association of daily light exposure with objective sleep measures in patients with PD.

Methods

In this cross-sectional study of 189 outpatients with PD and 1101 community-dwelling older adults (controls), daily light exposure was measured using wrist light meters during the daytime and light meters set in the bedrooms during the nighttime, and objective sleep quality was measured by wrist actigraphy.

Results

The median duration of exposure to ≥ 1000 lux light was significantly shorter in patients with PD than in controls. The median
