Abstract

Introduction

Accumulating evidence indicates that sleep health is worse in individuals living with a neurological condition and may hasten neurodegeneration. The extent to which the sleeping environment, particularly air temperature and light, influence sleep health has not been investigated in individuals living with a neurological condition. This research aimed to explore, for the first time, associations between air temperature and light in the sleeping environment and sleep health in individuals living with a neurological condition.

Methods

The sleep health, including the domains of sleep quality, duration, and disorders, of 46 individuals with a neurological condition was measured using the Sleep Health Index. Air temperature and light data were captured across seven days using a light/temperature data logger positioned next to the participant’s bed. Data recorded during the participants’ sleeping periods (determined using a sleep diary) were analysed. Linear regression models were used to assess the associations between air temperature and light and sleep health (including domains).

Results

This study showed that for every additional minute of low (10 to 50 lux) light exposure during sleep periods, sleep quality decreased by 9%.

Discussion

Our findings suggest that low light exposure during sleep periods may be detrimental to the sleep quality of individuals with neurological conditions.
