Helmets and caps using near infrared light are currently under study for neurodegenerative disorders like Alzheimer’s disease and Parkinson’s disease. They are also used to treat anxiety disorders.
A 2019 article published in the Journal of Photobiomodulation, Photomedicine, and Laser Surgery, titled ‘transcranial photobiomodulation with near infrared light for generalized anxiety disorder, a pilot study’ looked at 15 subjects with generalized anxiety disorder using an 830nm near infrared light head band with an intensity of 30 mW/cm2 (2.4W total) 20min daily for 8 weeks. They noticed a significant reduction in anxiety, as well as significant improvement in sleep.
This non-invasive technology is very promising to treat various conditions.
