Red Light Therapy / LLLT Cures Hypothyroid?

[tara]

Thanks dd99,
That'll why I had my reservations. Looking at one of those graphs, it would seem halogens are preferable to LEDs or CFLs, even warm white ones. Is that how you read it?

 

[dd99]

Yes, tara, that's right. I spent a long time deliberating over changing all our lighting (50-odd lights) to warm white LEDs from halogens for the long term cost savings, but my research (both theoretical and practical) led me and my wife to conclude that incandescent > halogen > warm white LED > cool white LED > CFL.

Interesting, I'll look into this and report back.

Meant to post this before: http://www.amazon.com/Illuminators-Ligh ... 850+nm+led

Should this work according to the study?

Thanks, cantstoppeating, that's interesting. But it's counter to what others have said in the forum about the spectrum of warm white LEDs, which appear to have a spike in the blue wavelengths. I'm on my mobile, so can't post images, so here are some links with graphs:

In addition, there appears to be some risk of eye damage from (admittedly cooler) white LED lighting:

I personally find LED lighting irritates my eyes, unlike halogens or incandescents which have better spectrums. (My brother in law is a TV presenter and they've had to remove LEDs from the studio because of the high frequency flickering and irritation to presenters eyes when they look directly at a light.)

The best and reddest, of course, is candle or fire light.

There does seem to be an emission of blue light from LED bulbs that do not have a red tinted coating.

I still prefer using LED bulbs with a makeshift solution of red filter paper like below. If you're doing your own lighting setup, get creative with the use of red filter paper which blocks all light but the red spectrum. And you don't need to buy a 'warm light' LED, choose any and slap on the red filter and you get the same blue-blocking effect.

A study on the use of amber tinted glasses to improve sleep by blocking blue light.
http://www.ncbi.nlm.nih.gov/pubmed/20030543

...At the end of the study, the amber lens group experienced significant (p < .001) improvement in sleep quality relative to the control group and positive affect (p = .005). Mood also improved significantly relative to controls. A replication with more detailed data on the subjects' circadian baseline and objective outcome measures is warranted.

My favorite and I think the best wavelengths + best feel/tone combo
is a 300W incandescent utility bulb.
They are like $5.
http://www.ruralking.com/300-watt-c...3Md2i-ByidD9KOx_5qGibUgSgoxzBc2IKlBoCePbw_wcB

Next would be a 500W halogen.
Best in my book for sheer power and production.
They have a little UVA...is that such a bad thing?...Vitamin D...
But they get very hot and are very bright and rather oppressive.
You can get them in the USA at Lowes for under $15.

I'll be having a say in some home lighting in the next while, so wondering what will be practical for living areas. I'll go with cheap and bright in passages, but kitchen and living room I want to have at least some supportive light in ceiling fittings.

I have tried a red light therapy bed much like this one
http://www.ebay.com/itm/Red-Light-Thera ... 1120086769
It lasted 14 minutes. I felt good at first then felt over stressed from too much stimulation at once I suppose.
I am unsure if the bulbs are very good (flouro) despite being 633nm.

If you feel over stressed that means your glycogen is empty and/or you use it too long. You need to eat and get your glycogen full first before using red light therapy.

That definitely fits with my experience. I felt better another time when I had eaten plenty beforehand.
The same place had a red light therapy chair with halogen bulbs. A couple of times I stopped early when it felt like more than enough.

 

[FredSonoma]

Anyone currently experimenting with this? I've been doing it for about 3 weeks now, not sure if it's helping. I have an 850 nm infrared LED.

 

[bluewren]

Yes Fred, I am doing the same.......850 nm. Have only had 2 sessions so far, of 20 mins duration. Am aiming for 10 sessions.

Trouble is, they run so damn hot. (halogen).

Thanks. Had not heard of those. They look quite interesting.

Do they run cooler than incandescent? They supposedly have similar light characteristics.

I think there are two types. The aluminium reflector halogens push the heat outward, so they feel hot. But if you have a fitting that can take the heat, non reflector halogens let the heat dissipate into the fitting, so feel much cooler.

I think they could be the holy grail of Ray Peat lights, personally. They mostly need the larger lamp screws unfortunately. They also have internal pressure which might make them delicate. But they range in pressure and can do the whole orange spectrum or the whole red spectrum, with much less infrared than incandescent or halogen.

I look forward to you riding this to ground, Such!

I'm fine without more hazards in the house...

This is what Dr. Hamblin from Harvard recommended me: http://www.larsonelectronics.com/p-4520 ... 940nm.aspx

Seems pretty intense, but that's what he recommended. 850nm model, floodlight.

[ilovethesea]

Would 1400nm do anything, or is that a waste of time? It's a device that you hold to the area around your eyes: http://www.triabeauty.com/eye-wrinkle-correcting-laser
I don't know if that means it's red light, blue light or something else.
