Summary
Matt Maruca discusses the principles of the "Light Diet" - a framework centered on how light exposure affects human health and biology. Maruca, known for his work on circadian health and light science, explores how different wavelengths of light influence the body's systems and why optimizing light exposure is a foundational health practice. The conversation examines the relationship between sunlight, artificial light, and human wellbeing.
Key Points
- The "Light Diet" framework for optimizing health through light exposure
- How different wavelengths of light affect human biology
- The role of sunlight in health and circadian rhythm regulation
- Impacts of artificial light on wellbeing
Key Moments
Modern windows block infrared and lower cell function
Energy-efficient windows filter out infrared light that powers mitochondria, creating excess oxidative stress in the body.
"coming into our windows and into our houses and our cars is we're immediately killing ourselves faster. So it's a really interesting trade-off that we're making. Like we're actually immediately lowering our body's cellular function, brain function, energy levels, quality of life. I mean, this is serious. This is not like a joke or hyperbole or exaggeration. It's super simple. When you block infrared light, which powers our mitochondria and our cells and charges up the water in our body, you create a lot of"
AM sunlight builds melatonin that blue light drains
Morning sunlight through the pineal gland builds melatonin reserves, but indoor blue light exposure during the day depletes them before bedtime.
"And that it's sort of like filling a bucket full of water and then you poke it with holes and then that melatonin slowly just goes away. And then when you actually try to go to sleep because you haven't held on to the melatonin, it can't be released. And so that's why people are like staying up and they can't sleep or fall asleep. And this is one of the things that your glasses helps to prevent, right? Yeah."
Blue blocking glasses: best bang-for-buck health tool
Compared to expensive saunas and devices, a $100-150 pair of blue-blocking glasses moves the needle most for circadian health.
"super duper duper over like one of the highest overly marked up industries in the world. Um, but so then they would go ahead and for the lenses, like a super high tech specialized lens, like for example, there's another company that makes a blue light blocking lens that blocks not nearly enough of, of the significant range of the most important range. Um, you know, for, for our, our standards now, but basically, um,"
Use red or orange incandescent bulbs at night
Red or orange incandescent bulbs eliminate blue and green light at night. During the day, open windows and skip artificial lights entirely.
"Um, so that's, that's what I would recommend to people. And that's good. But in general, if you have natural light in your house, like windows, open the windows, don't use any lights during the day is what I do. And then at night, don't use any lights at night. Uh, generally use candles or yeah, that's basically it. I use a red light headlamp that"
LED red light panels need low flicker and low EMF
Matt Maruca announces upcoming red light therapy panels designed for proper wavelengths, low flicker, and low EMF at a reasonable price.
"developed with the experts putting out all the right wavelengths of light that we need to be getting the very high doses of the specific wavelengths that people need for photobiomodulation and all of these types of things low flicker, low EMF, etc. We're going to be releasing that pretty soon for a pre-order so that's going to be really cool so people can get something at a good price, at a reasonable price for the level of what we're offering and we're going to be"
Near-infrared sun exposure creates melatonin locally
Exposing skin to sunlight triggers local melatonin production in the cells, and IrisTech software can reduce blue light from screens.
"You're able to create local melatonin, according to Nathan. That means you may want to consider getting some shorts that allow the sun to penetrate."
