Can new LED light therapy improve mental health and well-being?

September 19, 2018

SFU postdoctoral fellow Myriam Juda is studying whether new LED lighting that mimics natural sunlight can affect the body’s natural circadian rhythms and improve mental health and recovery.

She's using the programmable LED lighting technology to see how it affects the rest-activity cycle, sleep and psychological well-being of patients who have a co-occurring substance abuse disorder and a mental health disorder.

In the study, the LED lighting is automatically programmed to change in colour and intensity as the day progresses, beginning with with a sunrise, then a more intense, blue-enriched light during the day, a sunset and, during the evening, a dimmed red light.

Juda is conducting this research into human circadian rhythms during a Mitacs Accelerate internship with BC Hydro and the Burnaby Centre for Mental Health and Addiction (BCMHA).
