This is a fantastic fact filled presentation. Thanks. With regard to the timing of exposure in the range of 650 - 900 nm, Glen Jeffery, PhD stated that early in the morning is the only/best option. Is this constrained by filtering of light coming through the atmosphere or is it related to the receptivity of the person upon waking? To the point, If I am a person who wakes up at midday from a darkened room, would I find benefit exposing my skin/eyes as soon as possible (to artificial lamps of appropriate wavelength) or has the ship left the mooring? Hoping moderator can answer this.

[@homeopathywellness1719]

​@williamwightman8409 Excellent Q! I've been on this topic of red light and far/near infrared for over 15 years and one of the teachers of mine said, the red light is strongest when the sun is at the horizon, which is when the angle is just right for the red light to be greater than blue; it is also at sunset, btw!

[@ChristineSaunders-x2m]

I am blown away. I was made aware of his studies by just going through my morning Twitter read and someone reposted your talk. To my surprise, GJ published the work with bees in PLoS1 in 2016! Why are more people not talking about these absolutely groundbreaking findings?? I was in awe of the slide where he mentioned that that truck drives who delivered the bees to California and Texas increased the survival rate of the bees by exposing them to red light…WOW!!! As I continued to listen and came to the part about “modern day scurvy”, I literally took my lap top outside to finish the talk. I really appreciate the historical links, the links to evolution…this resonates with me significantly. Thank you, Michael, for this uplifting interview.

I recently started going down the rabbit hole of red light therapy after researching a health issue regarding horses. One and only one veterinary discussed red light therapy for certain health issues. Coincidentally, I was recently diagnosed with a tick born illness, not Lyme but I took a chance and bought a rlt device. Everyone, including my holistic friends said I couldn't beat the illness without antibiotics but I did! Granted I included herbs, diet etc and red light therapy daily. I'm 55 and feeling great. I live near the North Canadian boarder in NY and continue to use it daily on my third eye, back & abdomen. I'm not totally transformed into a new human but I certainly feel much better. The biggest and most noticeable difference was that I didn't succumb to the deep depression I usually feel in the fall heading into winter! I've always hated living here especially after being born in Ft Lauderdale Florida. This is my first fall and winter season that I remained energetic and optimistic! Clearly this therapy works. This video was incredibly interesting and informative. I'm pleased that I watched it as I was about to disregard it and watch something entirely different.

Thanks to Prof. Jeffery as well for his fantastic work Mitochondria are almost everything, from aging, to diabetes and madness. Just a few days ago i had kind of an insight into my own metabolic condition: having quite good overall health, the only thing which s not good is the non-fasted glucose baseline. Despite the fasted glucose is 87, the non-fasted glucose is 98. I addressed the question about mitochondria and glucose to a med practitioner specialised in the field, and... did not receive an answer. I was chasing that conundrum now for 2 years.... The other part of aging is the immune system, both its decline in creativity due to thymus involution and capability to fight off intruders. I would be very much interested in the effect of NIR light on the complex between dhea, growth hormone, macrophage activity, CD38 and CD8/4 +/- lymphocytes.

Remember that NIR exposure benefits are dependent on frequency of short daylight exposures ideally, every few hours if you are living and working in NIR starvation indoor environments. Light from any bulbs, do not provide the same benefits as the daylight does. And, we need the dark as much as we need the daylight rhythm, so the research seems to inform IMHO.

@23 min. Glen speculates, based on Bee experiment, that a single dose of red light at around age of 40 might carry humans through. But if memory serves, mitochondria in humans turnover every 1 to 4 weeks. So it seems that from a mitochondria perspective in humans one would want at least a weekly dose. There might also be a synergy with methods which boost mitophagy, such as fasting (or very low calories) maybe 1 day every week or two. anyhow, a lot yet to learn.

[@monnoo8221]

the population of mitochondria is constantly being renewed, with a wide varriety of half lifes. he point is, that red light seems to help to repair mitochondria, such that their majority is healthy. Both healthy and damaged mito may reproduce. and note, that their is a metabolic hypothesis of cancer, which can be seen as a statistical game where the probability of a cell transitioning to a cancerous state depends on the number of damaged mitochondria, their degree of dysfunction, and the cell's genetic susceptibility.

It is important to take them on an empty stomach at bedtime each night. They are excellent scavengers of dead protein cells. Be well all.

[@RayKinney-d6u]

Yes, but just first getting our light diets better, so we are not eating 'junk light' after darkness sets in in the evening, enables huge benefits to increase depth of slow wave sleep in the first two hours, by increasing the paralysis necessary to 'throw switches' in the brainstem to initiate the cleanup crew mechanisms in the glymphatic system in brain, to phagocytose the mis-folded proteins and recycle them. Blue light toxic effects w/o NIR, disrupt this natural depth of paralysis necessary.

If you go out in the sun when your shadow is at least twice as long as you are tall, the blue wavelengths will be filtered out of the sunlight. But, even if you lie in the sun to get your vitamin D during the middle of the day for 5 or 10 minutes, the red light is still there. Does it fail to affect the mitochondria like afternoon light? Don't know. As to that, I wonder if it takes darkness or sleep to reset whatever is affected by the red light? edit Or maybe it had already been switched by exposure to earlier daylight in the people who went out in the afternoon, and didn't cause an effect.

@@jetterbuglove A graph was shown at about 12 minute mark which showed an increase in a number of cytokines, chemical messengers which among other things can stimulate immune function and inflammation. Chronic elevation of many of these cytokines, like IL-6, would indicate something negative about one's health status. But it is normal for many of these to increase temporarily, maybe over the course of hours, as part of an adaptive response with the net effect being that your over health is improved. My point in mentioning "time course" was that we really need to see how these cytokines respond over time - do some stay up too long in some people? Does intensity or duration of light exposure impact how long they stay elevated? Another example is ROS (reactive oxygen species) which is generated for a short period during exercise but then subside shortly after. This elevation in ROS improves the body's ability to respond to ROS but increasing natural background level of antioxidants. But you wouldn't want ROS to stay up all the time or for long periods.

[@peterz53]

@@jetterbuglove Sorry to hear. I've had multiple issues too, still do, plus just getting old. What has helped me a lot is a combination of daily physical activity, mostly 5 to 6 miles of walking spread throughout the day, but starting with a 20 minute walk in the early morning, Eating quality food, mostly plant based, but almost no ultra processed, and trying to get enough sleep. I also eat two meals within a 9 or 10 hour window (TRE). Sleep, an issue for me, is helped a lot if I don't eat or drink alcohol with 3 to 4 hours of bedtime. Even better if I drink no alcohol. Sauna might help too. On NIR or plain old IR, just being outside in the shade an hour or so a day will get you quite a bit, or sit with your face shaded in the direct sun. You might have blood work done to check for level of toxic metals, although that might be a reach. And check for mineral balance, magnesium, zinc, etc. A study of Fire fighters was done where they donated plasma every month or so to see effect on chemicals they are exposed to and found that plasma donation was effective at removing persistent toxins. It may be a reach, but you could try monthly plasma donation (not whole blood) for a year or so t your local blood bank. It should also help reduce inflammation and studies (2020 conboy lab) have shown multiple positive effects in older lab animals on removal of some of their old plasma. In any case, good luck.

I’d be interested to know if people who live in sunny places have less Macular degeneration. Even if they spend most of their time indoors, they are still exposed to far more sunlight than I am in a high latitude. And…is there more MDG in higher latitudes. I’d like to also know about how latitude affects a body’s response to sunlight.

[@monnoo8221]

red light is a way to repair mitochondria. macular degeneraion has been shown o be related to mitochondrial dysfunction. The risk for that to develop is massively influenced by nutrition (too much sugars, carbs, too little lutein) and eye stress, like extreme contrasts: LED headlamps in vehicles, bad light hygieneat the working place. So, it is better to avoid damage than needing repair, but if damaged, then red light def. helps

[@dirkheyer6871]

A lot of Fitnessstudio's have LED Lights and when you think you do something good for your health, maybe the LEDs have to much blue light!!!😮 So the best would be to go every day into the sunlight for some minutes, but would it reduce the negative effect of the blue light before in the Fitness Studio?🤔

[@magnusdanielsson2749]

Istarted looking at finding light sources for red light, seeing of the "red light therapy" panels are so expensive. Also some of them dont seem to have all of the red light spectrum due to claims of "how certain wavelengths" etc.. Seems like a shame that the incandecants got replaced. Never really understood the argument of them being a waste indoors seeing how the heat will warm the house to some extent. At the same time loosing out on the full spectrum light seems like a real loss. I guess getting a fire place is a good idea if one can manage that. But how about infrared heating panels? Theyre typically in the 700-1000 um range wich I guess would satisfy the required wavelengths? Been thinking about infrared saunas also but as I understand it research dont see the same benefit from them as a from a regular sauna? This whole area seems a bit muddy to me. I recently saw that theres research saying blue light have no detrimental effect at all. Makes you wonder.

[@conqueragingordietrying123]

I think the best option is getting red light exposure from sunlight (but not too much sun exposure, which can photoage skin). If that's not possible, red and/or near-infra-red light to supplement. As Glen mentioned in the video, the panels don't have to be expensive.

Hmmm - I put in LED’s that allow you to adjust/ control their temperature to 2700,3000,or 3300 kelvin. The 2700 temperature is similar to incandescent bulbs. If I set them to 2700, shouldn’t they be beneficial even though they are LED’s?

[@wattsobx]

No, that’s just the temperature but the light spectrum behind it still has tons of blue and how LEDs work you get a nonstop flicker versus a steady burn from the filament and incandescent bottom line LEDs are horrible for our health and incandescent are amazing. I’ll be not nearly as efficient.

[@geoff_onYT]

I'm actually lightly concerned that light therapy might accelerate aging in some tissues. If red & infra-red light cause the mitochondria to ramp up their ATP production (i.e. our basal metabolic rate is increased), this may be somewhat analogous to doing the opposite of caloric restriction, which is proven to extend lifespan in rodents & probably primates In general, you want to slightly reduce metabolism to extend lifespan. the whole "Live Slow, Die Old" thing & burn the fire/furnace slowly rather than going "full bore" This is why we need an outcome longevity/life span outcome study in mice to determine the potential of red light therapy for anti-aging, similar to what the Interventions Testing Program does for drugs. Speculating based on biomarkers & mechanisms doesn't tell us what we want to know

[@conqueragingordietrying123]

Interesting insight, thanks @geoffwhite3385 Even on CR, mitochondrial function declines during aging, albeit more slowly than ad lib. If red light therapy works, it could potentially slow that process further. As you mentioned, we need long-term trials...

[@jamesgilmore8192]

I agree with you Geoff regarding lifespan and aging acceleration. Effects of red-light are hard to measure in general in humans, whereas the retina is much more sensitive. Even if you did everything right at home, it's doubtful you could measure any effect. It's an add-on to other approaches that have larger effects.

depends on the power, most lamps and panels are around 50 milliwatt per cm2 or more - so sit 3 feet away from those for a short time , like max 10 minutes, like 3 times a week not more, the eyelid hardly blocks any light, if they come with goggles wear them, I assume your lamp doesn't, red light at low power for 3 minutes in the morning is good for the eyes, slows ageing of the eyes if you do it a minimum of once a week especially if you are 40 and over, like power of 8 milliwatts per cm2 - 25 mW/cm2 and can also improve color vision, depending on the individual (does with me) , if the light seems really bright to your eyes wear goggles or don't sit in front of it, some people are extra sensitive, for eye illnesses, consult your doctor / optometrist
