Infrared light reduces the viscosity of water surrounding ATP synthase, enabling its rotor to spin faster and produce more ATP.

"this rotor also has water around it. And the water is viscous. So, if we can reduce the viscosity of the water around the rotor, the rotor can spin faster, right? Makes sense. You have lower viscosity, the rotor can spin faster, thus producing more ATP. And that's exactly what infrared light does. So, infrared light can be absorbed by this water around ATP synthase, reducing the viscosity of the water, and then ultimately producing more ATP." (said at 0:11:08)

The speaker presents this mechanism as an established fact ("that's exactly what infrared light does"), whereas in published biomedical literature it is a proposed theoretical and biophysical model developed primarily by Andrei P. Sommer and colleagues. In vitro nanoindentation experiments demonstrated that red/near-infrared (NIR) light can reduce the viscosity of interfacial water layers, leading to the hypothesis that lower interfacial water viscosity around the ATP synthase rotor decreases frictional drag and enhances ATP synthesis. However, direct real-time measurement of this exact mechanism inside living human mitochondria remains unproven, and it remains a competing hypothesis alongside classical photoacceptor models (such as cytochrome c oxidase).

  "Here, we wish to suggest a physicochemical mechanism which assumes intramitochondrial water viscosity gradients and consistently explains two cellular responses: The decrease and increase in ATP synthesis in response to reactive oxygen species and non-destructive levels of near-infrared (NIR) laser light, respectively. The mechanism is derived from the results of a new experimental method, which combines the technique of nanoindentation with the modulation of interfacial water layers by laser irradiation."

  "By reducing the viscosity of the nanoscopic interfacial water layers within and around the mitochondrial rotary motor in oxidatively stressed cells R-NIR light promotes the synthesis of extra adenosine triphosphate (ATP). Based on the results of our own work and a review of the published literature, we present the effect of R-NIR photons on nanoscopic interfacial water layers in mitochondria and cells as a novel understanding of the biomedical effects R-NIR light."

LED lighting damages mitochondria.

"So, one, they have LED lighting, which is damaging their their mitochondria" (said at 0:30:50)

The claim that LED lighting damages mitochondria overstates preclinical findings. While high-intensity blue-wavelength LED exposure can induce reactive oxygen species (ROS) accumulation, mitochondrial depolarization, and cellular apoptosis in isolated retinal cell cultures and rodent models, these laboratory models use intense, direct light exposures. There is no high-quality clinical evidence demonstrating that standard ambient indoor LED room lighting causes systemic or ocular mitochondrial damage in humans under normal daily conditions.
