A 2024 systematic review and meta-analysis published in Frontiers in Psychiatry analyzed 11 randomized controlled trials and found that red light (photobiomodulation) therapy significantly reduced depression symptoms across all study groups.
Researchers concluded that red light acts as a non-invasive neuromodulation technique, stimulating brain cells at the mitochondrial level to help regulate mood and reduce feelings of low energy, fatigue, and loss of pleasure.
This drug-free approach offers a promising complementary option for those looking to naturally support their mental health and emotional well-being.
