I’m attaching a two-page report about new research into the effects of red lights (photobiomodulation) and on gait in Parkinson’s Disease.
The Spanish researchers separated the participants into two groups, one group having real 670nm red light exposure and the other having sham light exposure. The participants didn’t know whether they were getting the red light or the sham treatment.
All participants were assessed for different movement activities before and after the study period.
The participants given the sham treatment were no different at the end of the study time. The participants given the real photobiomodulation all improved in their walking and movement.
The researchers commented, “Our findings are in agreement with those of a previous study which that reported gait improvements in PD patients after trans-cranial photobiomodulation, as well as with other clinical studies that suggest that photobiomodulation could be a potential strategy against neurodegenerative diseases.”
I’ve been reading articles suggesting that Alzheimer’s disease is linked with a disruption of brain wave patterns, especially the gamma waves which are predominant in the brain when we are concentrating and focussed.
One group increased gamma wave activity in Alzheimer’s mice by pulsing light. In this research, it wasn’t the light that was of interest to the researchers, it was the pulse rate. They used 40Hz, in the gamma brainwave frequency range.
Here is a great report about that experiment and it’s implications.
…stimulating neurons to produce gamma waves at a frequency of 40 Hz reduces the occurrence and severity of several Alzheimer’s-associated symptoms in a mouse model of the disease.
It seems that pulsing the light does more than enable red light to penetrate more deeply into the brain. Pulsing at 40Hz seems to stimulate the brain’s immune and clean-up cells, the microglia to get cracking with brush and pan.
I have visions of microglial cells dancing to the 40 Hz rhythm as they clear up brain rubbish, including the proteins that accumulate in Alzheimer’s – amyloid and tau.
In 40Hz pulsed red light, the brain gets the benefits of the red light action inside the cells, and the benefits of brain-protection activities stimulated by brainwaves responding at 40Hz.
Fascinating stuff, isn’t it.
Meanwhile, if you are feeling worried that your Eliza or Cossack doesn’t pulse, don’t fret. The daily light dose is doing its work. More.
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?
