Researchers have found that this act initiates the process of healing a large number of health conditions such as high blood pressure, high cholesterol, diabetes, sinusitis, dementia and various viral infections." - http://www.drgcohen.com/site/healing-approach/intranasal-light-therapy/ http://www.drgcohen.com/site/healing-approach/intranasal-lig... The more panacea it is, the more woo it probably is, eh? [Edit: NB. Nitric Oxide is produced in the paranasal sinus cavities[1], and when inhaling through the nose it gets drawn into the body. It appears to be involved in arterial flexibility, increasing blood flow, decreasing blood pressure, immunity, neurotransmission, and relatedly treating erectile dysfunction. Humming appears to increase the production of Nitric Oxide[3]. Maybe the red light up the nose just makes you breathe through your nose?] [1] https://thorax.bmj.com/content/54/10/947 https://thorax.bmj.com/content/54/10/947 [3] https://www.atsjournals.org/doi/full/10.1164/rccm.200202-138BC https://www.atsjournals.org/doi/full/10.1164/rccm.200202-138...
