Red and near infrared lights – can they help degenerative neurological diseases?
Tag: Near infrared light
Near infrared light starts just at the edge of the visible spectrum – we can see 670nm deep red, but as the wavelengths lengthen then our eye just can’t make them out. We can just see 810nm in daylight, we can just see 850nm in a darkened room, but we can’t see 940nm.
I’ve had a query about 12V near-infrared LED strip, especially 850nm LED strip.
You can see 850nm, but only just! 850nm is at the very edge of the eye’s ability to see. If you turn on the 850nm LED strip in a dark room, you will see a nice pale red glow. It’s red, but to our eyes it seems pretty dim. That’s good, that means it is working.
Today I caught up with a lovely man who had started wearing an Eliza bucket light hat nearly a month ago. His Eliza has 670nm and 810nm and he uses each wavelength for 10-15 minutes, one straight after another.
Eliza isn’t pulsed. She just puts out continuous light.
He reported feeling a lot better in himself. He said he had more energy and more interest in doing things. He had been out in the garden much more than previously and was enjoying life a lot more.
Friends had been commenting on how well he was looking. As did his general practitioner who apparently doesn’t yet know that he is using an Eliza light hat on an daily basis!
Another significant thing is that he can now hold a cup of coffee without spilling it. He is convinced that his tremor has reduced.
For all those DIY light hatters out there, this story shows that continuous light works. Don’t fret about pulsing, just get that red glow on your head every day.
If you have looked at the availability of rolls of red and near infrared LED lights, you will see that there is a bewildering array, between orangey-red (630nm) to out of the visible spectrum so that you can’t see it at all (940nm).
So what, you ask. Surely it doesn’t matter? Surely red light, near infrared light – it’s all the same? One wavelength is as good as another?
There is good evidence now that pulsed light is more effective than continuous light. Maybe the cell batteries, the mitochondria like to have a little pause in between receiving a pulse of light energy and directing it into the cell as metabolic energy. It makes sense.
The other reason is that by pulsing the light, the light dose is then the average of the pulse-ON and pulse-OFF. This means you can push the power in the pulse-ON, knowing that it will be offset by the no-pulse time.
I know of several people who have gone on to pulse their LED-based Elizas and Cossacks, and I have nothing but total admiration and envy for them, but there is no way I could do that.
The reasons that I have not previously mentioned the value of pulsed light is because;
1. I couldn’t give instructions to achieve it
2. I didn’t want anyone to devalue the effectiveness of continuous red/near infrared light.
Daily unpulsed red light better than no red light.
If you are using your Eliza or Cossack with continuous red/infrared light, do not be tempted to chuck it in the corner and refuse to use it because it won’t pulse. It is still doing its very best for you, and that is a lot better than nothing.
