Photobiomodulation as an adjunctive treatment for depression and anxiety. Meta-analysis shows significant improvement. Panacea.

Depression and anxiety disorders are among the most common mental health conditions. In addition to medication and therapy, photobiomodulation is increasingly being investigated as an adjunctive treatment.

Meta-analysis evidence

A meta-analysis in Frontiers in Psychiatry (2023) concluded that photobiomodulation significantly improves depressive symptoms. Transcranial photobiomodulation in patients with severe depression and anxiety disorders showed significant improvements as early as week two and four.

Neuroscientific mechanisms

Photobiomodulation improves cerebral blood flow in the prefrontal cortex - crucial for emotion regulation. It modulates neurotransmitters (serotonin, dopamine), reduces neuroinflammation, and has neuroprotective effects.

Important

Light therapy does not replace professional help but can be a valuable, accessible addition with a favorable side effect profile. Always in consultation with your healthcare provider.
