Ok, let's have more research info.

A normal human body luminesces mainly from the head; the color of the
luminescence is orange-red tinted with a little bluish-green. Red light is
emitted from all over the body of a man who is getting angry and forms a thick
halo. The inventor suggests that this is due to leakage of the internal energy
of the body. When the angry man is irradiated for 15 minutes with the apparatus
of the present invention, he will feel relaxed and the anger is relieved. At
this time, the red light around the body disappears from the photograph and the
status of normal luminescence is resumed.

One provocative study found that when some people with allergic rhinitis were
treated with intranasal exposure to low-energy, narrow-band red light, their
congestion was significantly, although not completely, relieved. Light therapy
may help suppress oxygen radicals and have a positive effect on calcium channels
in the immune system.

Dr. Brunler felt that flooding the body with red light helped rid the body of
excessive uric acid deposits and dissolved uric acid crystals in joints.



The eyelids are translucent to light transmitting about 10% (or 25 lux) in the
red end of the visible spectrum (above 700 nm), with the transmittance declining
to to 1%-2% in the green and blue end (below 500 nm).



Red light tends to increase EEG amplitude most efficiently at higher beta
frequencies, and the color itself seems to increase vigilance. Its efficiency
also varies as a function of certain aspects of cognitive style and ability to
visualize. It therefore appears to be the most appropriate color to use if beta
stimulation and increased vigilance are the desired result.



Red light was emitted onto the knees of 50 patients with osteoarthritis of the
knees. Those who received the red light therapy reported that their pain was
significantly reduced as compared to the group that had placebo light therapy



The depth of penetration is defined as the depth at which 60% of the light is
absorbed by the tissue.

There is little penetration up to 600nm, due to absorption by the various
peptide bonds, chromophores, porphyrins, haemoglobin, oxyhaemoglobin, and
photo-inducible components such as urocanic acid and melanin (Wilson and Jaques
1990). From 600nm to 700nm there is a steep rise in penetration (about 2.5 times
the distance), due to decreasing haemoglobin absorption, and then penetration is
roughly constant above this region to about 1300nm, with a small dip at 960nm
due the high absorption at this level by water (Smith 1991).

Visible red light, at a wavelength of 660 nanometers, penetrates tissue to a
depth of about 8-10 mm. It is very beneficial in treating problems close to the
surface such as wounds, cuts, scars and trigger and is particularly effective in
treating infections.

Infrared light (904nm) penetrates to a depth of about 30-40 mm, which makes it
more effective in the treatment of joints, deep muscle, etc



Calcium intake was also shown to be wavelength dependent. The most effective of
the wavelengths tested were 660, 820 and 870 nm. (Young, S. et. al. Effect of
light on Calcium Uptake by Macrophages. Original Articles. Lasers in Surgery and
Medicine. Supplement 1991 by John Wiley & Sons Ltd)

670-nm LED light therapy decreased the embryonic mortality rate by 41%,
resulting in increased embryonic survival and improved hatching success in eggs
exposed to 200 ppt dioxin. The eggs were treated once per day from embryonic
days 0-20 with 670-nm LED light at a fluence of 4 J/cm2
(http://www.liebertonline.com/doi/abs/10.1089/pho.2006.24.29)

There was observed a substantial decrease in overall and third-week mortality
rates in the light-treated chickens eggs. Overall, there was approximately a
41.5% decrease in mortality rate in the light-treated embryos (NL: 20%; L:
11.8%). During the third week of development, there was a 68.8% decrease in the
mortality rate in light-treated chickens (NL: 20%; L: 6.25%). In addition, body
weight, crown-rump length, and liver weight increased as a result of the 670-nm
phototherapy. Light-treated chickens pipped (broke shell) earlier and had a
shorter duration between pip and hatch.
