Red and near infrared lights – can they help degenerative neurological diseases?
Tag: LED Lights
LED lights are now commonplace. Even a decade ago, they were expensive, but now they are available for very reasonable prices. They use much less energy than other light sources, and they come in a range of wavelengths. They are now becoming the standard light-type being used in research into the health effects of red and near infrared lights.
I’ve had a few queries about the use of laser lights. I can understand the allure of a laser, as its coherent light with such total focus is pretty impressive.
LED lights used to be very expensive. In the last decade the costs of LEDs have really dropped, and we can now buy them easily and inexpensively. LED lights are not coherent like lasers – the light from the average LED lights scatters and shines over a bigger area.
Question: For lights on the head, are lasers better than LEDs?
Both have their place, but the previous dominance of laser lights is being whittled away by practicality and safety of LED lights.
For trans-cranial use, you want the red lights to scatter – you want coverage of the lights over the head. You also want to use the lights daily, safely and at home.
Lasers are a pain to use, they come with safety issues and they are not suitable for home use.
I’ve had lots of emails from people making a DIY light hat from the blog instructions. The tricky part is finding the best red LED strip.
670nm is hard to come by, as is 660nm.
The tendency is to stop work on the light hat, on the basis that it can only be made with the best possible LED strip.
The best thing is to get any old red LED strip and make a light hat as soon as you can and get it on the suffering head every morning – as soon as you can.
Then, and only then, start hunting for the elusive 670nm LED strip. And when you find it, make another light hat with the new LEDs. And give away your first one – there is always someone who can put it to good use.
It is far more effective to have red lights on brain than it is to have no red lights. Every day counts.
And remember – the Cossack is a far better design than the bucket Eliza.
I know that this term has been recently used in conjunction with red lights which is a pity. While it might make a thrilling moment on television, it gives a very inaccurate and misleading picture of how red lights work.
Even worse, it raises unnecessary fears.
The answer: red lights won’t fry your brains.
If you follow the guidance given in this blog, you’ll notice that there is occasional mention of heat, because some LED strips can get warm. And anything warm on your head can be uncomfortable.
This is easily avoided by making yourself a light hat that is open and not closed in – the Cossack is the best DIY design.
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?
