Red light therapy is a literal light in the dark to possibly improve mental health and mood changes. While there is a clear need for more research on this topic, we would like to look at a few of the most significant studies that have shared incredible results.

  • In a 2018 clinical study, 20 participants suffering from mood disorders and MDD were administered transcranial red light therapy for 20 to 30 minutes twice a week for eight weeks. After only eight weeks, the HAM-D17 scores in the real group were significantly lower than in the placebo group.
  • In a 2018 case study, a 76-year-old woman with severe mood swings, depression, and anxiety was irradiated with near-infrared light. The daily forehead irradiation proved possibly effective in reducing mood changes, negative mood, and anxiety symptoms, and her overall functioning improved.

Red light and brain health

A few studies indicate that red light might stimulate the production of one extremely important brain chemical, melatonin.

This chemical is a naturally occurring hormone released to help you sleep. As this light is believed to possibly promote melatonin release, after the therapy, you might feel much calmer, and if you do this therapy at night, you should be able to sleep faster and improve your sleep quality.

That being said, as we know that insomnia is one of the biggest factors that make mood changes and low mood even worse, having a quality good night’s sleep and being well-rested might significantly improve your mood and make you feel more energized, calmer, and more positive in general.
