UV is produced in all fluorescent tubes. It's how they work. UV is produced, which then strikes the phosphor coating on the inside of the tube. The light is absorbed and then re-emitted in visible wavelengths.
How much UV finds its way through? I'd certainly hope that it's not much, but most fluorescent tubes are made in China, and their quality control systems are.....spotty.
Incandescent bulbs also emit some ultraviolet. Not much, but they are blackbody emitters, and some of that wavelength distribution extends into the ultraviolet. The hotter the filament, the more UV there is. (Look at the left side of the x-axis, mainly anything below 400nm.)
Second, those "natural health" sites often have a habit of dipping into fiction ("pseudoscience") quite often.
Checking...
Dietary changes, increased physical activity, time-honored remedies that include herbs and homeopathic remedies, and rest—these should always be our first-line approaches.
By the time you get to a 30X dilution, there is no measurable part of the original substance left.
The precise mechanism of how homeopathy works—why greater and greater dilutions should have more and more power, and why the violent shaking with impact should be so important—is still unknown.
Yes, they've got some BS.
And the manner in which it works is known: Placebos are impressively effective on our species.
"Here, drink this. It will make you better."
"Wow, it works! I feel great! What was it?"
"Nothing, just distilled water."
Every electron in every cell vibrates; so if everything vibrates, it would seem fairly logical that one vibration must affect another. One current hypothesis is that the succussion of the dilution strengthens the vibratory resonance of the substance, even when the physical component of the substance has been removed.
Now they're really diving into the deep end of the pool of BS.
They should've thrown in the word "quantum" somewhere, just for good measure. :awe:
In the meantime, vicious attacks on homeopathy—in the US and UK and elsewhere—continue, both because it is an affront to conventional medical thought and an economic threat to the patent drug business.
Because it's an affront to rational thought. Because it can prevent people from using real medicine, and instead using something that's as useful as swallowing a quarter-ounce of distilled water. Because it is a waste of money and resources on an industry that is without value.
[Homepathic remedies are] far safer than FDA-approved drugs.
Well sure, a useless pill with no active ingredients is going to be pretty safe...assuming that the inert filler material isn't an allergen or toxin.
In fact, the UV rays are so strong that they can actually burn skin and skin cells.
I'm around fluorescent tubes every day, and I'm about as white as you can get. Sunlight is what burns me, and in a damn hurry, too. (I'm not too far south of Canada, and I still burn in under an hour outside.)
Mercury content: A few milligrams, maybe. I've seen some that have less than 1 milligram.
I like how they don't bother quantifying the amount of UV emission at all and are content to let the reader simply know that UV is emitted.
They did say, "In fact, the UV rays are so strong that they can actually burn skin and skin cells."
Also from the article:
There are also light-emitting diodes (LEDs), which are mercury-free—though LEDs emit blue light, which can be disruptive to sleep, as we noted in our 2012 article.
(
Psssst! So do all other kinds of normal indoor lighting.) LEDs just have a more defined band of it, and they're available in lots of different color temperatures. Get one that's a warm color temperature, 2700K-3000K, with a CRI of 80 at the very least (I prefer >90), and you won't tell the difference between that and an incandescent bulb.
2700K Philips Rebel LED wavelength distribution.
5650K Philips Rebel LED wavelength distribution.
In either one, you can see the defined band of blue light, over toward the left. More of it is allowed through on the higher color temperature emitters, making the light look more blue. In the warm white emitters, more of the blue is absorbed and converted to longer wavelengths, giving a redder light.
But, any kind of cool white source, whether it be filtered incandescent, fluorescent, LED...anything, could conceivably mess with your sleep - it probably would be because that spread of wavelengths, which is indeed heavier on the blue, mimics what you'd see during the middle of the day; not "because they're evil new technology that's out to getcha." Lighting that's shifted toward the red end of the spectrum is closer to what you'd expect in the evening, so some part of you's evolved to associate that with sleep.
