    Studies are showing that artificial light is linked to breast cancer, particularly shift workers. I saw a show on TV the other night that talked about how artifical light inhibits production of melatonin which apparently is a cancer inhibitor. People who are working on this have actually tested the whole spectrum of light versus melatonin production and found that blue light is the most favorable in which to work in at night.


    All that belongs to human understanding, in this deep ignorance and obscurity, is to be skeptical, or at least cautious; and not to admit of any hypothesis, whatsoever; much less, of any which is supported by no appearance of probability...Hume

    Maybe keep the things covered at work and actually get outside once in a while...

    That's interesting, because other studies have shown people who spend lots of time away from natural light are also at more risk from SAD, so perharps it's time to rethink some of the architecture of some of these buildings to enable more natural light into working enviroments, or at the very least start to rotate enviroments so that it isn't always the same people working under artifical light, either this or send the staff off to the Sun for an extra 4 weeks holiday every year to build up their melatonin levels.

    It's unclear whether it's the frequencies of the light, or the unnatural times for light exposure creating the problem. We did after all evolve in the tropics with roughly 12 hour day and nights.

    Originate maybe, but not evolve. Once humans went into Europe, the evolution went a different way, with breeding preferences to lighter skin, hair and eyes.

    Just a thought here but it would be interesting to do some contrasting studies of countries where there is naturally more sun light with those with much less, also if there is anything that they do in the later countries that might have some sort counter balancing effects, such as something dietry maybe.

    Zinthopropos, I mentioned this topic some time ago on this forum and I was ridiculed, I even mentioned that electric light was the main cause of bad vission in young and older people. The studies goes even farther it states that electric light contributes to lack of melanin growth which is connected to the lack of brain power. If you come into Los Angeles at night and see the amount of lights lightening up the night skies, it would not directly make you think it could be affecting the people who live in it. Even the plants in the lighted cities cannot sleep at nights although they need both lights meaning day light, and night light.

    There is still more to come because demographics is telling the same story. I know the hawks are waiting to ask me for proof but now a days even the proof that is given needs proof. The slide in birth rates especially in caucasians to 1.3 per family are leading back to a melanin deficit and most of it is coming from the use of electric power. I am surmising it is because of the low vibration rate of the waveform we use. The reason that blue light is better is because it is nearer to the ultra violet rays and that is good to a certain extent than white light. Mind you black people can absorb more blue light that clear skinned people. Ultra violet tends to burn you while infra red seems to cook you.

    If you take a study that is valid- then run with a whole bunch of assumptions based off of it- sure... people are going to ask you to support what you say.

    What do you do with a study that is incomplete and you do not know that it is incomplete, yet you quote what you do not know? Any knowledge only goes up to a certain point. What was common becomes esoteric and versa visa.

    What studies are incomplete? Do you think that making up or assuming additional details outside of the study accounts for anything you feel may be missing?

    There is a lot more to this study than meets the eye, frankly I am supprised that this is coming out at this time when other studies have identified the problem with the decling birth rates of caucasian and clearer shinned peoples. There are so many things going on at the same time that studies and real knowledge are being criss crossed over the now social networks. people are becoming knowledgable not by experience but by google. They google the knowledge base and hypothosize and try to bring the universe to a pin point where they can claim to know the universe.

    It really does not matter where you look, every one is making a claim on planet earth. Electric light is not a present phenomeon, it goes and comes like anything else. If you use too much of anything it will harm this earthly body. Sience is not even a word if it does not serve the people. If there was any trust in the capabilities of the planet then it would be left alone to have a life of its own. Melanin is a prerequisite for life on planet earth, if you do not produce it, life on planet earth will be short lived. It is not man made or God made, it is. This substance is the balancing substance that keeps the DNA in harmony with the evoluting force that permiates through the cosmos.

    The lights of the inner cosmos harmonises with the lights of the outer cosmos which we know as light and dark. These two energies create a ballance in our beings
    that enables our actions in the light time or day time. If we upset that balance it will cause a disruption in our energy flow and cause all kinds of diseases. Melanin is produced in the Pineal gland and shows on the pigment of the skin. Very important to know is that the production of melanin is tied to fertility.

    You asked a question in #8 and I am responding to it.
    I am not talking about you studying something and know the totality of that study. If you know the totality of any study you know the cycle, or not?

    Explain something here... What is the problem in a declining birth rate? Can you be specific?
    What was the identified cause of this problem in these studies?

    I note that the reference Zinj was quoting seems to be from people selling lights. Possible commercial bias?

    There is no doubt that lighting has an effect on human biology, and people who work at night under artificial lights end up more stressed than people working daylight hours. They also, on average, do not live as long. Even so, I would be a little careful about accepting as true something that seems to come from a biased source.

    Thats what you guys always say when the studies come from your own sourse.

    I think you should read up a little on melanin, and melatonin, and while you are at it look up the effects of electricity and electric light on the human tissue. Oh and look up where the pineal glad sits and what it does.

    I'll do that.

    Prof. Haim presented one of his studies showing the adverse effects of exposure to light at night -- particularly short wavelength blue LED -- in the blind mole rat and in seeing rats, both of which showed varying levels of damage to their metabolic rates, hormone production, body mass, and oxygen consumption following exposure to LAN, as well as suppressed levels of melatonin production, which is responsible for tumor growth. "We expect to find similar results of damage from human exposure to LED lighting," Prof. Abraham concluded, and pointed out that "Western youngsters are typically surrounded by this sort of lighting in the confines of their own bedroom: from the smartphone, computer screen, and television."

    There was an excellent documentary recently on 'The Nature Of Things' titled 'Lights out!' Unfortunately the video is only available to view in Canada.

    Scherezade posted some links earlier- but it threw me for a loop as one seemed to be suggesting that blue light was the problem...

    Aha! The problems of blue light and sleep. I've installed F-lux ( f.lux: software to make your life better ) on my computer to cut down on this problem.

    It's not at all as subtle as the blurb suggests - though it does make a difference. It seems to work on a 12 hour schedule regardless of time of year. Basically, while you're working in late afternoon a softish, peachyish tone washes into the upper half of your screen if you're looking at it when it happens. You might notice it when it happens, but you never, ever notice it in the mornings until, suddenly, the whole screen seems to brighten.

    It might not suit all people. But one thing I would definitely recommend - every parent should instal it on every electronic device their schoolchildren use. As a tutor, my heart sinks when I check with kids or their parents about their screen use and their sleeping habits. Far too much screen. Far too little sleep. If parents can't supervise, or they run out of steam when 'parenting' stubborn kids at 9 pm, they can at least be reassured that if their kids insist on using computers, etc long after bedtime (or they wake themselves up to do stuff in the middle of the night) when they eventually go to bed their ability to go to sleep won't be adversely affected by the screen use itself.

    It is my understanding from what I have read and researched that blue light does interfere with melatonin production and so one should limit their time in front of a screen before retiring or use some form of light protection or filter as adelady suggests. I have a light tint in my eyeglasses which may do the same thing as I can be at my laptop until minutes before retiring and then be sleeping soundly within minutes of hitting 'horizontal hold', and never a problem hearing the alarm, often wakening minutes before it goes off, usually after 4-5 hours sleep when I am on graveyards. I take my rest between 6-10:30 p.m. on those shifts.

    Light dependence
    Production of melatonin by the pineal gland is inhibited by light to the retina and permitted by darkness. Its onset each evening is called the dim-light melatonin onset (DLMO).
    It is principally blue light, around 460 to 480 nm, that suppresses melatonin,[32] proportional to the light intensity and length of exposure. Until recent history, humans in temperate climates were exposed to few hours of (blue) daylight in the winter; their fires gave predominantly yellow light. Wearing glasses that block blue light in the hours before bedtime may avoid melatonin loss. Kayumov et al. showed that light containing only wavelengths greater than 530 nm does not suppress melatonin in bright-light conditions.[33] Use of blue-blocking goggles the last hours before bedtime has also been advised for people who need to adjust to an earlier bedtime, as melatonin promotes sleepiness.[34]

    Far from it my friend, I think this is an exelent topic, I am sure there will be some live discussions on it. I myself have always been interested in the two lights that governs our lives, so no ridicule here, more like praise.

    if you can remember at one time we had TV's where the screen was bombarded with electronen. There were large magnets on the necks of the TV tube. People use to sit very close to the screens and at the time we were told the screen would emmit light xrays. There were some things that the public did not know. When you turned the tv on or off, there was a bust of exray energy. The high voltage builup was sometimes 30,000 volts depending on the size of the screen. This constant flash over longer periods of time lead to a breakdown of bone structure and eye diseases.

    Some of these thing we have and use on the planet are sometimes helpful, but what does that mean. In reality what we do is after the damage is done we look at the sientific value.
