photon light application restores serotonin levels in the brain's sleep-regulating region
Laser acupuncture reversed para-chlorophenylalanine-induced reductions in hypothalamic serotonin and 5-hydroxyindoleacetic acid (5-HIAA) in insomniac rats.
What this means for you
Serotonin is a key chemical your brain uses to regulate sleep, mood, and relaxation. When levels drop, falling and staying asleep becomes harder. Research suggests photon light application may help restore serotonin balance in the area of the brain that governs sleep cycles — a finding relevant to anyone who wakes up unrefreshed or struggles to wind down.
