| Annotation | Ageing is associated with a decrease in the quality of night sleep with 30% of older people experiencing chronic insomnia. Treatment of insomnia typically involves the use of hypnotic medications, and these have been associated with a range of negative outcomes in this population cohort. The present Australian study used a naturalistic design to explore the relationship between light, activity and night-time sleep quality in a sample of 33 healthy older subjects. Findings demonstrated a significant positive relationship between activity and sleep quality. Ambient light was shown to have a significant impact on night-time sleep, though the study identified a critical exposure threshold of 3000 lux. Factor analysis demonstrated the independent contribution of these two variables to subsequent sleep quality. These findings identify the potential for the development of non-pharmacological treatment strategies for insomnia in older people. (RH). |
