Red light definitions

Explains LLLT, Photobiomodulation and PBM.

You will have come across the various names for the use of red and near infrared lights. Michael Hamblin, one of the lead researchers in the area, has summarised the terminology changes beautifully in a recent article called (somewhat dauntingly) Mechanisms and Mitochondrial Redox Signalling in Photobiomodulation.

Low Level Laser Therapy (LLLT)

Almost 50 years ago in Hungary, Endre Mester found by accident, that a low power red laser noticeably improved wound healing.

It was initially thought that light delivered by a laser was the key factor in the wound healing, and so the term Low Level Laser Therapy, abbreviated to LLLT, was developed.

If you put “LLLT” in your favourite search engine, you’ll find a lot of references will pop up.

Neuroinflammation vs Neurodegeneration

I’ve been reading an interesting 2016 review article called Cytokine networks in neuroinflammation.*

Click here for the abstract.

Some of the differences between neuroinflammation and neurodegeneration are beautifully explained. Both diagrams come from this article.

Background

Cells in our body and brain produce cytokines, small proteins that are powerful and wilful little beasties. They provide a very effective means of cell communication, and can “orchestrate complex multicellular behaviour”.

Over 300 different cytokines have been identified, but some of them have shown that in one situation they will behave in one way, but in another situation the same cytokine will do the complete opposite.

Cytokines are part of the body and brain’s response to something going wrong. But cytokines themselves can go haywire (called cytokine network dysfunction or dysregulation) and set up and maintain cascades of activity that can ultimately cause harm to the tissue.

Public lectures in Melbourne – 1 July 2018

If you live close to Melbourne, you have a rare opportunity to hear two excellent lectures about the effects of red light on the head* for Parkinson’s and Alzheimer’s Disease.

Who are the speakers:

Prof John Mitrofanis, University of Sydney and Prof Liisa Laakso, Griffith University

What are they talking about:

Prof John is giving an update on case studies of people with Parkinson’s Disease using red light hats on a daily basis.

Prof Liisa is presenting recent research evidence on the effects of red light in Parkinson’s and Alzheimer’s disease.

When:

Sunday 1st July, 2018

9.00 – 9.45 am – Prof Liisa

9.45 -10.30 am – Prof John

Where:

Workshop 1 & 2,

The Larwill Studio, Art Series Hotels, 48 Flemington Road, Parkville, Vic 3052. Map

Cost:

These two lectures are free to the public, but you will need to book as numbers are limited.

Book your seat:

Email: natalie.amla@outlook.com

Background:

These two public presentations have been coordinated by the Australian Medical Laser Association, AMLA, and is part of a two day conference called Photobiomodulation Therapy.

*The official term for red light on the head is PBMt, shorthand for trans-cranial photobiomodulation.

Caution

Red and near infrared lights are complex. We know only a little, but we do know about the importance of wavelengths, dose and comfort.

I’ve just added a new page – Caution .

Check it out as it collates some of the words of warning from various blog posts.

 

 

 

 

Eliza dosage – when and how long?

A few people have asked how long a light hat should be worn.

A previous post about the Goldilocks Effect is really important to read, as it describes the research on the odd effect of too much red light.

More red light is not better – it can make things worse. Neurones are finicky fellows and we must respect this.

So how long should you wear an Eliza light hat, or any kind of red/near infrared light on the head? As everyone’s light hat is different, it is impossible to give absolutely firm advice. But based on what I’ve observed over the time of making many and varied light hats, I’d suggest the following considerations.

How to help your doctor

I’ve had a number of people tell me that conversations with their GP or specialist about red and near infrared lights haven’t gone well. One chap took his newly-made Eliza to show his neurologist, who roared with laughter and said that it would be very handy at Christmas.

I remember my reaction when patients brought in newspaper clippings about the latest and greatest cure for something – I’d keep a smile on my face and inwardly groan.

If you are getting less than supportive noises from your doctors, don’t get cranky with them, because they are trying to protect you. There are lots of charlatans and snake oil merchants out there, and people with chronic diseases are easy targets. They are worried that you and your family are going to be taken in by costly rubbish. If you read about the beginnings of my learning about red lights, here, you’ll see that I was also very skeptical.

So what can you do?
