Just 1 minute of red light is effective
-
@cs3000 Just one minute in the morning was enough to improve eye health in a study . It only worked in the morning as far as I remember. There seems to be something about red light in the morning being very healthy . Huber man talks about that a lot. It regulating circadian rhythms etc.
Red light also increases exercise recovery.
And it changes the micro biome in a beneficial way.Ray also said that after sunbathing shining red light on the hair (or skin) for a few seconds will prevent damage.
Dare to think.

Just 5 minutes a week (20mw/cm2) increased lifespan, bone size, cartilage amount in aged mice

That's pretty decent for a little bit of light. -
@cs3000 - Thanks, I like this thread. But my approach to eye health (in addition to red light) is to get a lot of lutein in my diet on a daily basis. See the thread https://bioenergetic.forum/topic/3281/is-lutein-a-magic-bullet-for-cognition?_=1732048163020

Pretty interesting, thanks for sharing.
I sometimes turn on my red light for many hours at a time in the winter with some idea of emulating sunlight... I actually did that yesterday and today I felt quite tired and my eyes were hurting.
Perhaps that is counterproductive.

Some time ago, I posted about it on RPF here.
Below is that post screenshot as I don't know whether the link is generally usable.

is this done in combination to having an incandescent bulb? i remember hearing red light should be greater but needing the full spectrum.

@Lejeboca - Your screenshot works great. Glen Jeffery, University College London is the last named author in the image. He has been interviewed a number of times on YouTube. He has explained the there is nothing magical about the 670 wavelength; it was just the wavelength of the red LED bulbs that were commercially available at the time. I got the impression from the videos that his department operates on a shoestring budget.
The density of the mitochondria is greatest in the eye and it is their circadian rhythm that responds to the early morning light. Their response begin shortly before dawn and they do not respond well in the afternoon.
Full spectrum light of course would be the healthiest.

When we’re talking about reduced effectiveness from too much red/nir exposure, are we talking about actually reversing the benefit, or just wasting time

Probably depends on what benefits we are talking about.
From my own experience: Red-light exposure can be pretty stimulating and if I overdid it in the past, I would sometimes get some negative symptoms like fatigue or low blood sugar symptoms. I now treat it like a form of exercise. I make sure to have enough fuel in the system and I don't use it for more than ~ ten minutes a day, mostly less.
Some anecdotal evidence, since the effect on eye health was mentioned several times; I have used red light pretty regularly for almost 20 years now (back then for acne) and I never cared about the warnings not to look into it. I didn't shine it directly into the eyes intentionally, but I also never closed or covered them. And I'm the only one in my family, including extended family (aside from one cousin) who has good eyes and never needed glasses. Could have many reasons of course, but maybe the red light was a factor.

interesting. were you limiting your exposure all that time?

I never did more than 15 minutes a day or so, maximum 20. But I didn't limit it deliberately, I just didn't see the benefit in using it more.
