Rogan shares one of the most concrete personal longevity testimonials in the episode: after years of red light therapy three to five times weekly, he no longer needs reading glasses he once needed at 2.5x magnification. Sinclair validates this biologically: retinal nerves lose their identity and energy production as we age, but near-infrared light revitalizes their mitochondria, restoring function to nerves that aren't dead, just forgetting how to work. He notes that red light and Viagra (tadalafil) actually share a mechanism involving nitric oxide signaling. A fascinating digression follows about a Japanese researcher who argues that the modern absence of violet light — due to indoor LED lighting — is causing the epidemic of myopia, because the lens and retina evolved to receive the full spectrum of outdoor light. The practical implication: spend more time outside.
