Podcast listeners on mobile click here for full show page. Blocking blue light is one of the most important things you can do for your sleep, energy levels, hormones, overall health and your longevity. It has been by far the most important change I've made to my health routine. Want to sleep better? Block blue light. Want to have more energy (by sleeping better) Block blue light. Want to prevent cancer? Block blue light. Want to prevent your vision from declining with age? Block blue light Want to regulate your hormones? Block blue light. Want to prevent diabetes? Block blue light. I've been talking about the idea of blocking blue light for over a decade now. I just looked at my Amazon purchase history and I bought my first pair of blue blockers in 2012. I even devoted an entire radio show to light which you can listen to below. The idea of blocking blue light is gaining more and more attention in the natural health space. Sometimes though it gets lip service and it's not really explained in a way that's powerful enough to elicit emotion or change. Why Light Matters Humans are light beings. Everything about our biology and physiology is run by light. The primary driver of our circadian rhythm is light. Yes other things affect our circadian rhythm (and they also should not be ignored) like food, body temperature and hydration but light is the primary driver. “We know today that man, essentially, is a being of light. And the modern science of photobiology … is presently proving this. In terms of healing, the implications are immense. We now know, for example, that quanta of light can initiate, or arrest, cascade-like reactions in the cells, and that genetic cellular damage can be virtually repaired, within hours, by faint beams of light. We are still on the threshold of fully understanding the complex relationship between light and life, but we can now say emphatically, that the function of our entire metabolism in dependent on light.” - Fritz Albert Popp For example when light enters the pupil in eye, those photons travel through your central retinal pathway making it to your suprachiasmatic nucleus (your master circadian clock). The pathway is as follows... Photon → Pupil → Lens → Retina → Retinal Ganglion Cells (particularly the photosensitive ganglion cells containing melanopsin) → Optic Nerve → Optic Chiasm → Retinohypothalamic Tract → Suprachiasmatic Nucleus (SCN) Every cell in your body has it's own
