In 30 seconds
This randomized controlled trial investigated the effects of self-administered daytime light supplementation on older adults (ages 63-92) in urban settings. The study found that greater naturalistic light exposure correlated with increased daytime activity, improved sleep quality, and reduced metabolic disorder incidence. Participants who initiated indoor light supplementation earlier experienced greater benefits.
Key findings
- Greater naturalistic light exposure was linked to increased daytime activity and better subjective sleep quality.
- Participants with lower naturalistic light exposure self-initiated longer indoor light supplementation.
- Supplementation onset before 10:00 was associated with lower rest-activity fragmentation.
Why it matters
Understanding the impact of light supplementation on older adults is crucial for promoting healthy ageing, particularly in urban environments where natural light exposure may be limited. This intervention could enhance overall well-being and reduce health risks.
