670nm red light exposure improved aged mitochondrial function, colour vision
- ankitml 2y agoThere are more than 1000 similar papers on red and near infrared. All pointing to its impact on mitochondria. Near Infrared (NIR) penetrates few cm, leading to its mitochondrial impact in muscle cells too. https://scholar.google.com/scholar?hl=en&as_sdt=0,5&q=near+infrared+photo+bioillumination+mitochondria https://scholar.google.com/scholar?hl=en&as_sdt=0,5&q=near+i...
- nwienert 2y agoI've looked into red light at least a handful of nights, I never can come away with a conclusion. It seems like it helps, but it also seems super likely it doesn't do much. I've added the super high intensity arrays to my cart even, before reading into various studies and anecdotes and just not being convinced. What's the most convincing argument for it?
- theoreticalmal 2y agoYou seem like you’re hoping someone will convince you to try it. Why don’t you get a cheap one and give it a shot and see if you feel any different?
- nwienert 2y agoI typically don’t buy things unless I feel they have some utility, and it seems the cheap ones likely don’t do enough to notice.
- its-summertime 2y agoLight is light.
- ben_w 2y agoSome wavelengths don't penetrate so deep, and not all bulbs are the same brightness. I've seen obvious lies on some product descriptions on internet listings, therefore I wouldn't trust a specification claim like "x nm" or "y lumen", and unless I had tools to measure them I would not rely on them meeting those specifications.
- PeterStuer 2y agoLumen does not measure much red light.
- ben_w 2y agoLumens being perceputual brightness means any package listing it for IR is definitely lying; but that only makes it a first-pass filter, "no false positives" does not mean "no false negatives". e.g. even when it's about visible light, well, do you trust this claim of 500,000 lumen?: https://www.amazon.de/Shadowhawk-Rechargeable-Extremely-Waterproof-Emergencies/dp/B099S4CR82/ref=mp_s_a_1_14_sspa?crid=3ME1GUAUAQW3M&dib=eyJ2IjoiMSJ9.rh7FTpSGCyMorJnM69NNjPk3kR6q-fUx7my6W6A07lKkMrJlSbO56gSQC80ueRI-8IVNhj49zKIeHDQECwewKZhEJHBPNtQlVv1E0dsjUWbWmtSUS-yzDqoQ3JBRJeTJzWstZO3Wn9ZQxq26D3O6_Q3Rwcvi7CnmGRF1VpKo6Nk9fgmYCzPpCMqpgYvph1Hwa8kdIftD_ouZ7u1NcMMv4w.O8DOQKOrFgsd3g5-PyDxBRxsxAJAn5co_xEK6_XA4Ys&dib_tag=se&keywords=million+lumen&qid=1739873150&sprefix=million+lumen%2Caps%2C89&sr=8-14-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9waG9uZV9zZWFyY2hfbXRm&psc=1 https://www.amazon.de/Shadowhawk-Rechargeable-Extremely-Wate...

- bethekind 2y agoBuild your own. But direct from Alibaba or mouser or digikey. The main science behind it is to hit the absorption peaks of a mitochondrial enzyme. You can make em bright, but be limited on how long you can use it, or dim and be forced to use it constantly for the same effect. Pulse width modulation is very important in this for penetration. High intensity allows for deeper penetration, but heats up cells causing stress. The ideal scenario is a really strong light, run at a really low duty cycle, allowing for both intensity AND low average wattage, this lessening thermal issues There might be other mechanisms of actions, as there are so many papers that say "light good", but until they can give a mechanism of action, I'm sticking with what I know
- Fethbita 2y agoI have been wanting one of these and on multiple occasions tried to find some good quality lights. I have not been able to find one that I feel is trustworthy. Do you have any EU based recommendations?
- ankitml 2y agoget a broad spectrum red light bulb, that is most well understood and is least risky. Cons is the targetted spectrum would be only a small portion of it but good thing is it is a 4$ cheap test. It worked for me for smaller issues, like minor burns, cuts etc.
- kenjackson 2y agoI've used it for a while now on my knees and ankles. Seems like it works. But honestly its hard for me to tell if anything works. I even question Tylenol. All of it seems like it may work some, but its not something I feel has a very acute impact at all. Without a controlled study, as an individual, how can I tell if my sprain got better in 6 days but would've taken 9 days otherwise???
- anon84873628 2y agoYou might want to look into BPC-157
- andreareina 2y agoBPC 157 has little to no reliable data to say it works. https://open.spotify.com/episode/6WLUUia6qZjVredWBuOlr6 https://open.spotify.com/episode/6WLUUia6qZjVredWBuOlr6
- cjbgkagh 2y agoA fair amount of anecdotal data though, it has helped me and others that I know. While the effect is pretty mild it is positive. Having a lifelong chronic condition I’m very sensitive to changes and have no discernible placebo effect. I’ve tried so many things that my prior belief when trying something new is that it wont work, so it’s a nice unexpected surprise when it does.
- BobaFloutist 2y agoGhosts have a fair amount of anecdotal data. Homeopathy has a fair amount of anecdotal data.
- cjbgkagh 2y agoI am aware of survivorship bias but for that to apply BPC157 would have to be killing people, this peptide is widely used so if it was killing people we would know due to investigations into their deaths. People usually hear about this stuff peer to peer and they report back to their peers if it helped or not, so there is a before and after, and for those people there isn’t a selection criteria biased on success. If people don’t report back then others become very interested in why.
- unclad5968 2y agoJust go outside, there is lots of IR out there. If it feels good then get whatever gadget you want to emulate it inside.
- bethekind 2y agoMost of the stuff online is overpriced and beyond the mitochondrial enzyme absorption spectrum, I can't find any reasonable mechanism for action. I think your hesitance is valid
- cowsaymoo 2y agoA family member of mine is involved in research into using red/NIR light to improve brain injuries outcomes. Apparently it can also irradiate passing blood which then circulates with the same mitochondrial clean up signals, so it has some secondary effects on non-penetrated areas. I got to try a prototype LED helmet that blasts 90 watts of lensed, circumspaced NIR beams through the skull for 4 minutes. I can say that an hour later it leaves me feeling mildly buzzed. The main effect I can identify is a mild and general sense of stamina/energy. I used it before/after an all-nighter and didn't feel as impacted as I should have; analogous to how you feel the next morning after drinking at age 20 vs. age 30. All anecdotal of course. They took the helmet away to give to a kid with an recent brain injury, but swapped it with a hefty 2-foot, 1800W panel. It comes with tanning goggles and instructions saying to be nude and 12 inches away from it for 20 minutes per day--so a bit quacky. But it's apparently big in professional sports clinics for speeding tissue and joint healing.
- prododev 2y agoI mean, it is kinda quacky to treat someone with that until it's demonstrated by science. I'm open to the idea that light is an important regulator, but that effect should be easily observable if it's truly effective.
- Etheryte 2y agoThe topmost comment in this comment thread starts with the fact that there are over a thousand studies on this already, no? Even if the whole effect isn't well understood, it seems like there is some science behind this.
- 0xEF 2y agoOne could argue that the research goes all the way back to Dr Frederick Cook aboard the Belgica during an Antarctic expedition I which they became trapped by the sea ice. The men suffered from multiple maladies, scurvy included, with one of the prescribed treatments being to stand nude near a blazing fire for an hour. If his notes are to be believed, the men saw some immediate changed in their overall health beyond simply getting warm. By some accounts, he became a bit of a fanatic about how much we humans need the sun, after that.
- mlhpdx 2y agoI have to wonder if sitting by a fire at night is analogous.
- selcuka 2y agoI remember reading somewhere that it is analogous to closing your eyes under the sun, as your eyelids only allow some wavelengths of sunlight. Not sure if that's accurate.
- mk_stjames 2y agoThe transmittance of light through the human eyelid is about two orders of magnitude greater at the start of the near-IR (~700) nm than it is at 450nm. [1] [1] "Measuring and predicting eyelid spectral transmittance" Journal of Biomedical Optics, Vol. 16, Issue 6, 067011 (June 2011) https://doi.org/10.1117/1.3593151 https://doi.org/10.1117/1.3593151
- bethekind 2y agoIt's quite analogous, especially for ideal intensity Bright enough to warm the body, but not thermally stress the cells. And yeah, closing your eyelids would block UV light from getting in and cross linking proteins and causing cataracts, while still allowing for NIR light to get in and speed up the mitochondria. Analogous for sure
- HumblyTossed 2y agoSo, to replicate the results of this study how long would a person have to do this each (morning?)?
- inciampati 2y agoWeirdly they didn't test nighttime exposure as an intervention. OK, "weird" means probably it was costly/hard to get people into a lab setting at 9pm... But it does make you wonder!
- 2y ago
- bluechair 2y agoAnecdotal, so take this with a grain of salt: I’ve used a pair of red light glasses from a Dr in the UK and saw noticeably improved vision.
- cenamus 2y agoWith those the same amount of red light would have hit your retinas anyways, no?
- AnthonBerg 2y agoYes, pretty much I’d think—but less of the other wavelengths. I imagine that this could serve as different enough input to matter. With the eyes being a very expensive and highly-strung instrument and all?
- alexey-salmin 2y agoProbably the pupils dilate due to overall decrease in light intensity
- m463 2y agoI remember reading about this wrt red light improving healing of burn victims.
- jensenbox 2y agoCan I do this with an LED strip and maybe home assistant in my office?
- trhway 2y ago>A single 3 min 670 nm morning exposure to the eye at energy levels approximately a log unit greater than found in environmental light it sounds like getting up early and getting out like for a run can be beneficial in one more way. https://www.researchgate.net/figure/Early-morning-6-am-relative-irradiance-of-the-sun-is-higher-in-the-visible-and-NIR_fig8_287807359 https://www.researchgate.net/figure/Early-morning-6-am-relat... : "Early morning (6 am) relative irradiance of the sun is higher in the visible and NIR spectrum compared to midday exposure (noon)"
- mitjam 2y agoYes and before reading HN on a screen which is my habit, unfortunately.
- imp0cat 2y agoJust need to redshift the screen. But the intensity will not be enough, unfortunately.
- khafra 2y agoA single 3min 670nm morning exposure may be more valuable in latitudes where the sun does not rise until after 8AM.
- RomanPushkin 2y agoI don't know wether it's true or not, but I liked the red light, and my spouse too. It helps - improves mood, heals minor pain, calms you down, and warms you up. It also helps with falling taking naps if needed, I fell asleep faster. Lots of joy for $70. I found vintage Kenmore red lamp with red bulb on eBay. I find it better than LEDs, since it emits heat as well.
- dr_kiszonka 2y agoI use a 10,000 LUX light therapy lamp in the morning and it does wonders for my mood. When I started, colleagues commented on my better mood without knowing about the lamp (obviously). It is amazing how large of an effect light has on us.
- imp0cat 2y agoIs that a red one? Or one of those "simulate the sun" full-spectrum ones?
- dr_kiszonka 2y agoIt is the full-spectrum one, not red. I should have been clearer in my comment.
- bethekind 2y agoThis is basically a mini grow light right?
- dr_kiszonka 2y agoYes, I think so.
- taraparo 2y agoI have one of those https://www.eye-power.co.uk/ https://www.eye-power.co.uk/ While I like the sensation using it I don't feel any noticeable effect.
- zanybear 2y agoHow old are you? What drove you to buy these?
- voisin 2y agoLooks really interesting. Wondering if I would need special equipment like they describe in order to hit the intensity they describe specifically on the cornea or if it would be effective enough to buy a 670nm red light bulb and sit near it in an otherwise dark room in the morning?
- zellyn 2y agoMy head canon is that sitting around drinking tea and watching the sunset is what humans need most…
- riversflow 2y agofor whatever it’s worth, I have found a lot of meaning in sunset runs.
- ziofill 2y agoIs this true only for vision? Mitochondria are in other places too
- crystaln 2y agoThere is a large amount of evidence for red light therapy for all parts of the body.
- pbmonster 2y agoA large amount of mostly inconclusive evidence! I don't know why the people running red light studies hate control groups so much. If you do that many studies, varying wave length and intensity for some of them should be trivial. Yet somehow they almost never do that. So: 90W mask or 1500W panel? Infrared, red light, or does yellow work just as well, maybe? The people doing near-UV therapy for skin conditions managed to do all that. There's a know effective wave length (it's always 311nm), there's dosage plans. There's licenced medical devices doing the irradiation. IR people seem less interested in all that.
- pjs_ 2y agoI like to read book in the dark with the red LED on my headtorch (so as not to bother gf) before I go to sleep. It’s prob 630nm not 670 but I get about two pages in and fall instantly asleep. Can recommend
- profsummergig 2y agoCould you please link to the product. I have trouble sleeping. Am interested in trying this technique. Thanks in advance.
- pjs_ 2y agoHere is the recipe. Don't skip any steps - Your room must be cold. If you stand around in the room you should feel kind of chilly - Your room should be quiet. If you have loud A/C which turns on and off that's a problem c.f. step 1 -- think hard about how to meet both requirements given your personal situation/constraints - Your room must be dark. Not necessarily pitch black but dark. No blinking LEDs. - A couple hours before bed, remind your brain that it is soon time to sleep - Your phone must not be in the room with you. Your phone sleeps in the kitchen. I cannot emphasize this enough. It's OK you are going to have a nice book to read instead - You need a real physical book. Books are cheap and make you more sexy and smarter. No Kindle - Here's the book I'm reading: https://www.abebooks.com/book-search/title/gormenghast/ https://www.abebooks.com/book-search/title/gormenghast/ - This is the headlamp I use: https://www.pelican.com/us/en/product/flashlights/headlamp/2750/ https://www.pelican.com/us/en/product/flashlights/headlamp/2... - There's nothing special about that headtorch -- there are hundreds of head torches you can buy with a red ~630nm LED. it's the standard red color LED. It would be interesting to swap it out for the 670nm wavelength described in the article though! - Actually that model is pretty heavy and just happens to be the one I bought for camping -- you could do a lot better/smaller/lighter e.g. Nitecore NU25, Black Diamond Spot 350 - You will feel like a clown when you put the headtorch on. That's okay -- you read books and sleep well, making you very attractive in the daytime. It's OK to look like a clown at nighttime - You are going to sleep on your back. You can do this, I believe in you. You are going to sleep positioned like Tutankhamun and for nearly as long - You need a reasonably firm pillow and you need to set it up right. It needs to support your neck and stop you rolling on your side. None of this foam bullshit it needs to have feathers in it. You are a human being not a cellphone. You don't sleep on plastic - OK let's get this bread. You lie down you turn off all the lights and you turn on your cool little headtorch. You get your head very well positioned on the pillow. You are about to sleep like a boss, you're going to sleep like Genghis Khan. You better get those covers tight because it's fucking cold in your room. Then you start reading. Hell yeah this book is so good. It feels so natural and rewarding and you remember that people used to write in ways that are outside our grasp today, no LLM or modern author can touch it. Within a couple of pages your eyes are shut. You find yourself holding the book with your eyes closed, barely awake. At that moment boom you put down the book, ideally switch off the headtorch, and disappear

- energy123 2y agoAre there any valid safety concerns with this? Or is it just the simple check: "as long as the wattage is low enough, it's fine."
- dr_kiszonka 2y agoMy experience with evaluating consumer medical devices ("lifestyle" and "fitness") is that what is on the box is often not what the device actually does. Besides wavelength and wattage, you would probably need to check for consistency, whether there aren't any spikes, etc. I don't know how much IR light is dangerous for the brain / what tolerances are acceptable.
- cowsaymoo 2y agoMore is not better. Research suggests optimal mJ/c^2/s dosages for each wavelength. Stuff on amazon is not going to be calibrated at all to dosage or even wavelength. Aside from being ineffective, there aren't dangerous side effects except prolonged exposure if staring into high intensity NIR.
- energy123 2y agoCan you explain more about optimal dosages and which products deliver those dosages? We get about 0.05 J/cm²/s of infrared irradiance from natural sunlight, so we'd probably want to be at that level, or above but less than an order of magnitude above it? One challenge is the irradiance drops off as a square a distance. So like 5 inch away vs 1 inch away is a difference of 25x irradiance.

[14] found that all three approaches could in principal achieve such specificity. However, because brain tissue is conductive, it can be challenging to confine neuronal activation by traditional electrical stimulation to a single cortical column. In contrast, optogenetic stimulation can be applied with high spatial specificity (e.g. by delivering light via a 200um fiber optic apposed to the cortex) and with cell-type specificity (e.g. excitatory or inhibitory cells); however, optogenetics requires viral vectors and gene transduction procedures, making it less easy for human applications [15]. Over the last decade, infrared neural stimulation (INS), which is a pulsed heat-mediated approach, has provided an alternative method of neural activation. Because brain tissue is 75% water, infrared light delivered near peak absorption wavelengths (e.g. 1875 nm [16]) permits effective delivery of heat to the brain tissue. In particular, experimental and modelling studies [[17], [18], [19]] have shown that 1875 nm light (brief 0.5sec trains of 0.25msec pulses forming a bolus of heat) effectively achieves focal (submillimeter to millimeter sized) activation of neural tissue Does NIRS -based (neuro-) imaging induce neuronal growth? Are there better photonic beam-forming apparatuses than TI DLP projectors with millions of tiny actuated mirrors; isn't that what a TV does? Cold plasma also affects neuronal regrowth and could or should be used for wound closure. Are they cold plasma-ing Sam (Hedlund) in "Tron: Legacy" (2010) before the disc golf discus thing? Does cold plasma reduce epithelial scarring? A certain duration of cold plasma also appears to increase seed germination rate FWIW. To find these studies, I used a search engine and search terms and then picked studies which seem to confirm our bias.
- crystaln 2y agoRed light therapy is vasty undervalued among the techie longevity crowd I know when compared to supplements, perhaps because of the large initial cost and lower portability of systems.

- FollowingTheDao 2y agoThe most important part of that paper is the first two sentences: "Metabolic rate and ageing are both regulated by mitochondria. Mitochondrial membrane potential, however, declines with age resulting in reduced adenosine triphosphate (ATP) production, which is a major source of cellular energy. Cellular decline is further accelerated with ageing by increased production of pro-inflammatory reactive oxygen species (ROS)1." Forget everything else. Why does "Exposure to long wavelength light (650–900 nm) in animals improves mitochondrial function, increasing ATP production and reducing ROS"? That is what needs to be figured out, because red light will not always increase ATP production and reducing ROS because we are all different. Genetics, nutrition, it all plays a role. It might be as well that red light helps in the short term but hurts in the long term. On ATP, do you know what the real name for ATP is Mg-ATP, That is magnesium ATP. Not enough magnesium, not enough ATP. (I am in no way claiming that magnesium is a cure all, just making a point.) What reduces ROS? Selenium, magnesium, Catalase, etc...

Has anyone gone down the rabbit hole here and have genuine product recommendations that roughly satisfy the conditions laid out in the paper? * Wavelength: 650–900 nm red light * Power output: 8 mW/cm² * Misc design choices: e.g. light diffusers * what other considerations???
- pseudosaid 2y agoMitsubishi makes the best leds. get ones made by them. the rest can be driven by whatever
- heyoni 2y agoMaybe, maybe not. At power levels high enough to be therapeutic you’re gonna want to think about cooling.

- goda90 2y agoI recently bought a panel on AliExpress for much cheaper than most of the branded one. There's not really reason for them to lie about the wavelength of the LEDs, so build quality is really the only risk factor.
- pseudosaid 2y agojust lie about the led itself as that is the costly component. Who is gonna measure wavelengths and hold them accountable? its a no brainer move to scam the most expensive component that also is hard to verify

- hombre_fatal 2y agoSo many grifters in this space. Someone I know desperately bought a $8000 red light therapy gun pitched to her by a chiropractor to help her father who had catastrophic brain damage from a stroke. :/ The gun has a dial on the side that lets you cycle through "Cancer", "Chronic pain", "Acute pain", and other ailments. https://neuro-solution.com/ https://neuro-solution.com/ Whatever legitimacy red light therapy has, it's set back by the legion of people trying to make money selling confusing products, and it's hard to tell what's legitimate or not. Between some red-colored LEDs glued inside an eye mask and those fan-cooled NIR array panels on aliexpress, what is legitimate and how do you tell? I think it's that confusion that seeds the field for people to say "none of it unless you're spending good money [on my product]."
- kubb 2y agoI hate it, and I'd consider this a crime akin to theft. It's literally taking advantage of people who don't have the faculty to defend themselves, and capitalising on their human weakness.
- goda90 2y agoFrom what I've read, it actually seems like a bad idea for cancer. Red light is not going to induce cancer like UV, but if cancer is already there, it'd get the same mitochondria boosting effect, essentially helping it grow more.
