This interaction can increase ATP production, improve cellular signaling, and restore metabolic function in damaged or energy-depleted tissues.Dr. Rountree explains how this mechanism has translated into clinical applications for chronic pain, musculoskeletal injuries, wound healing, and skin rejuvenation. By temporarily increasing nitric oxide release and improving microcirculation, photobiomodulation may accelerate tissue repair while reducing inflammation and pain signaling.The discussion then expands into neurological applications. Transcranial photobiomodulation, which delivers near-infrared light through the skull, is being explored as a potential intervention for neurodegenerative diseases such as Alzheimer’s. Early research suggests that targeted light exposure may reduce neuroinflammation, improve cerebral blood flow, and enhance glymphatic clearance - mechanisms that support cognitive function and brain health.Throughout the conversation, Dr. Rountree provides practical guidance on evaluating consumer devices. With many inexpensive products flooding the market, he explains how wavelength accuracy, energy density, and clinical testing determine whether a device delivers therapeutic results or simply expensive placebo.At its core, this episode reframes light as a biological tool: one capable of modulating mitochondrial function, improving tissue resilience, and potentially reshaping how we approach...","thumbnail_url":"https://img.transistorcdn.com/1b0HAhl7LyS1JMvttJBUPVo13Xhw89dNIYFNVWa7Un0/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS83NGVi/ODc5ZmE2MTI0Njdj/NWRjODE2NTkzNTQ0/ZjY0Yi5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
