Photobiomodulation as an Innovative Strategy for Night Therapy of Brain Diseases
When light stimulation (photobiomodulation, PBM) is applied during deep sleep, it enhances the brain’s natural waste-clearance system (the glymphatic pathway), accelerating the removal of amyloid-beta and improving cognitive recovery in animal studies.
Conclusion
“When sleep turns on, light can help cleanse the brain.”
Night-time PBM activates the brain’s natural cleaning system, promoting recovery and memory maintenance through precise timing with the body’s sleep rhythm.
