Morning Blue Light Therapy Found to Improve Sleep and Activity in Older Adults

A new study highlights the benefits of timed blue light exposure for enhancing sleep quality and daily rhythms in seniors living independently.

Research shows that morning exposure to blue-enriched light stabilizes daily activity patterns and reduces sleep fragmentation in older adults.
Evening exposure to the same light disrupts sleep, leading to longer times to fall asleep and lower sleep efficiency.
Participants spending more time in bright natural daylight experienced stronger daily rhythms and earlier bedtimes.
The study suggests light therapy as a non-pharmacological, affordable solution to age-related sleep issues, promoting better overall well-being.
Researchers emphasize the importance of maximizing morning light exposure while minimizing blue light in the evening for optimal sleep health.
