There are whole companies dedicated to selling this, Google red light therapy and you'll find a few. Novothor is the gold standard for athletes at $100k/pop. I myself jerry-rigged my own comparable unit and bath in it everyday- I haven't noticed eyesight benefits but I'm convinced I feel healthier and stronger as a result.

I am not sure about eye sight, but oddly it was HN where I read abou LLLT previously, this was link shared: https://careclinic.io/low-level-laser-therapy-photobiomodula... Not to spread conspiracies but who would continue to fund this type of research as its non invasive and can essentially weed out the day to day optometrist business complex?

What's the wavelength of the red you see when facing the sun with your eyes closed? I remember seeing some claim a few years ago (can't find it right now) that doing that every day would improve eyesight.

Not sure about the wavelength, but I believe the claim can be found in Aldous Huxley’s “The Art of Seeing” which is an account of vision therapies using the Bates method.

That's a good point.

So it looks like you need a bit more than a prism to see Fraunhofer lines, but there seem to be online description of how to do it with a with a prism and a CD, maybe you don't even need a prism, there seem to be 'make your own spectroscope' tutorials than mention building one with cereal box, and maybe a lens of some kind

The D line is probably more easily seen in a colored flame made by adding salt water to an alcohol-burner flame: https://en.wikipedia.org/wiki/Emission_spectrum#/media/File:...

that sounds like a project to do with my kids, thanks : )

This makes me think of Bulletproof Executive's self-improvement blog. He was always talking about mitochondria and hacking cells with certain light wave-lengths and lasers. I thought it was very far-fetched at the time... but maybe he was onto something. Related links: https://www.bulletproof.com/sleep/sleep-hacks/light-hacking-... He talks about the red light idea there and the crazy laser idea I'm remembering I thi…

Several years ago, Dave Asprey (Bulletproof Executive) was one of the most positive influences on my diet/wellness. It's too bad that his constant hustle, eccentricity, and "going against the mainstream" attitude rub a lot of people the wrong way.

Me too. These days, to me Dave Asprey's a mixed bag.

He's the guy who's claimed for years that he's going to live past 180. But in reality, he has aged in a frightening way, much faster than the average person. He looks 20 years older than he did 6 years ago.

Maybe it's because of too much biohacking? The body is just not built for so much modification for such long periods of time?

But I don't take issue with his pursuit, and I wish him well. Perhaps he'll prove us wrong when something suddenly clicks when he's 80 and he actually starts decreasing in age again. I'm not being sarcastic. If he wants to keep trying, good on him.

I suspect you do not need to use 670nm exactly, however I suspect you need to be above 650nm. Note that many red LEDs are at a lower wavelength (~630nm). So you need to search for deep red or by wavelength. You can use a OSA, but yes they are expensive. Spectrometers are typically cheaper, but still expensive (you could go to a university optics group and ask them if they could measure it for you). That said if you b…

Instead of trying to emit 670nm, why not just use a wide spectrum source and a 670nm bandpass filter?

Like the sun and your closed eyelids. Light transmission goes up with wavelength https://www.spiedigitallibrary.org/journals/journal-of-biome... (see figure 5.) To speculate, perhaps we have evolved to benefit from closing our eyes in the sun.

> walk for an hour most days I've started doing the 10,000+ steps for a couple of years, and yes there does seem to be a difference to my health and energy.

Why shouldn't it, all parts of the body needs a frequent stimulation, otherwise process of minimizing energy output (ie for tissue maintenance, repair of muscles and joints, etc.) kicks in. Our bodies are a bit dumb in this, albeit with good intentions - momentarily preserve energy, make body weaker long term. It made sense in the past though, otherwise we wouldn't be probably here.

Yes indeed, its interesting the different quantities I've noticed - like up to 17,000 my body really ramps up, I could do that every day, and often do, but I did 30,000 the other day I was tired the next day. Though when I started 5,000 was a major achievement. I'd love to see wider studies on this, like do muscles change? and how etc. I guess sports science focuses on athletes, Is there much average Joe science? apart from weight loss. I'm amazed also at how easy walking is, and how little calories I burn walking - which is why I started - to lose a few pounds.

Surely it’s not controversial to post a scientific publication supporting your claims. I suggest you Google-fu yourself.

A quick search turned up the following. The list is non-exhaustive and wasn't vetted in detail. 2017: Aging Retinal Function Is Improved by Near Infrared Light (670 Nm) ... "Our data suggest, 670 nm light can significantly improve aged retinal function" https://pubmed.ncbi.nlm.nih.gov/28129566/ --------------------------------------------------- 2016: Red Light of the Visual Spectrum Attenuates Cell Death in Culture…

Thanks for posting, I appreciate it. This effect is quite interesting.

This is why I bought a squatty potty and make sure to walk for an hour most days. Physical evolution does not keep up so well with modern society's pace of change and understandings therein.

My uncle would say he was analog in a digital world.

That's a great connection. If it's that simple (and explained by human evolution), that would be awesome.
