Preprint links 850-nm near-infrared light to lower glucose
A bioRxiv preprint reports that people in windowless offices exposed to desk lamps supplemented with 850-nm near-infrared light had reduced glucose measurements over a three-day experiment, while standard LED exposure was associated with increased levels. The study used an oral glucose tolerance test and continuous glucose monitoring.
