Near-infrared light is sometimes described as if it were a “charger” for the brain. Although memorable, that metaphor is scientifically imprecise. Light does not supply cellular energy directly, nor does exposure automatically produce a particular neurological or cognitive outcome. Photobiomodulation...

Mitochondria are often described as the “energy factories” of cells. The comparison is useful, but mitochondrial biology is more complex than simply turning energy production up or down. One area of photobiomodulation (PBM) research explores how red and near-infrared light...
