- Plastic – not too thin as these can split when you cut them.
- Internal diameter at the top around 260mm (~10.5 inches). Definitely no less than 240mm (~9.5 inches) and no more than 300mm (~12inches).
- Straight sides. Well, straight-ish sides
- Depth of around 190mm (~7.5 inches). If you can find one of that depth, then you are saved a lot of cutting and fiddling. If you can only find buckets that are much deeper than that, like the one in the pic above, then brace yourself for some cutting and fiddling.
- Colour of your choice. If it is close to Christmas, red could be nice.
I’ve just written up the story of our red/near infrared light hats.
It started in 2015 with a lampshade from an Op-shop and ends with a bucket. More
It’s been longer than intended since the blog was updated. During this time, a new article by John Mitrofanis was published in April 2017, called Why and how does light therapy offer neuroprotection in Parkinson’s disease? You can download it here: Link.
This is a great article with much detail explained with great clarity. Even better, it is only two pages.
It poses two critical questions:
- Can red/near infrared light protect brain cells from dying?
- If yes, then how does the light do that?
Early versions of our devices used LEDs of a single wavelength. Different wavelengths were tried over time, but in the early cases each device featured LEDs of a single type (and therefore wavelength).
John’s research planted the idea that multiple wavelengths could improve the outcomes being achieved, so we started making devices with two or more types of LED.
Constant knee pain makes it hard to be active, so in mid 2015, I did a lot of sitting and reading. One of the books was Norman Doidge’s The Brain’s Way of Healing.
Chapter 4 covered the effect of red and near infrared light on the brain and spinal cord, and there were some remarkable stories told. In passing, Doidge mentioned the positive effect of red and near infrared light on arthritic joints and damaged tendons.
I went hunting on Google Scholar and found some medical journal articles that Continue reading “The Beginning”
Sunlight has a range of wavelengths, and these have been classified into four main groups: ultraviolet, visible, near infrared and far infrared. We can see the light in the visible spectrum (red, orange, yellow, green, blue indigo, violet) but we can’t see ultraviolet light and neither can we see infrared light.
Much research has been done on the effect of the sun’s ultraviolet light. It can cause premature ageing and increases the risk of skin cancers, hence the warnings to wear sunscreen to block those wavelengths from hitting the skin.
Until recent years, the effect of red and near infrared light, had been of less interest to medical science. It is now an area of increasing research, and the implications seem to be huge.
