The history of medicine is rich in constantly changing theories and views and not only that but also old truth based upon basic observations of human nature. In that way, air and light , always were the sources of life for both mind and body. They were the stepping stones for the physical and mental wellbeing which in the early day was all covered in mystery. The uses of sun’s rays in Roman and Greek times was widespread common knowledge. Hippocrates himself was describing the uses of the solar baths as dietary and hygienic purposes. Herodotus on the other hand already begins to describe the uses for therapeutic treatments with sunlight. The treatment was not only for external cuts and bruises but also for internal illnesses.

 

And just like that emperor Aurelian (A.D. 270-275) advises light treatment of general cachexia, obesity, arthritis, edema, womb infections and chronic bladder diseases. Also the light therapy included treatments for colic, jaundice, atrophy and general constitutional anomalies in children.

The sun baths that treated nervous systems, paralysis, hypochondria, hysteria and even epilepsy were in great demand. The sunlight was not only used on the body as a whole all the time but rather localized to some area of the body at times. An ancient roman technique - to sunbathe after having a meal. This tradition still remains to this day in parts of Italy, in the Alps valleys people still follow it. Thanks to that kind of treatment, people of Tessin; Boizenburg, live until very old age and within the people there is a saying, “Where the sunlight reaches, doctors can’t get to.”

 

In the 18^th century, physiologists Edwards and Moleschott, by setting up a row of experiments, managed to prove the effects of light on the metabolic rate in animals. Edwards has shown that a baby frog cannot develop well in the dark when Moleschott, during the experiments, discovered that by shining a light on to the frog made it produce 3 times as much carbon dioxide as in the dark and the increase production depends on the intensity of the light. As it is known, Carbon Dioxide is the byproduct of respiration and mineral exchange in the body. Also, the visible light spectrum (390-750nm) does not have any negative effects on the body. The sunlight, with clear sky, separates into UV radiation (0.1-390nm) - 10%; Visible light (390-750nm) – 40%; IR radiation (750-10000nm) – 50%. Most important is the visible affect on the plant life with the production of chlorophyll. Without light, the only life forms that survive are fungus and several other primitive life forms.

The effects of the visible lights on animal and plant cells were formed from the times of the single cell organism and continue to this day. Mineral exchange, cell synthesis, utilizing products for a living cell all happen thanks to the visible light spectrum which also has antibacterial properties. In 1877 it was first proven by 2 physiologists Downes and Blunt that sunlight can either kill bacteria or slow down their rate of development. This was later verified in the 20^th century with experiments, that even a single light specter of one set colour but with a slightly different wavelength can have a different effect overall because in the cell there are molecules called photosensibilisers which take in a specific quant with a predetermined wavelength (440nm – blood porphyrin, 450nm - flavin nucleotide, 460nm – bilirubin). These are all the principles upon which “Avers” products are based. Same goes for “Avers-Sun” as it is like having am mini sun in your house or office or even medical center.
