For millennia, people had one apparent and dependable supply of sunshine – the Solar – and we knew the Solar was important for our survival.
This may be why historic religions – resembling these in Egypt, Greece, the Center East, India, Asia, and Central and South America – concerned Solar worship.
Early religions have been additionally usually tied up with therapeutic. Sick individuals would flip to the shaman, priest or priestess for assist.
Whereas historic peoples used the Solar to heal, this may not be the way you suppose.
Since then, we have used mild to heal in quite a few methods. Some you would possibly recognise in the present day, others sound extra like magic.
From warming ointments to sunbaking
There’s not a lot proof round in the present day that historic peoples believed daylight itself might remedy sickness. As a substitute, there’s extra proof they used the heat of the Solar to heal.
The Ebers Papyrus is an historic Egyptian medical scroll from round 1500 BCE. It accommodates a recipe for an ointment to “make the sinews […] versatile“.
The ointment was fabricated from wine, onion, soot, fruit and the tree extracts frankincense and myrrh. As soon as it was utilized, the individual was “put in sunlight”.
Different recipes, to deal with coughs for instance, concerned placing components in a vessel and letting it stand in daylight. That is presumably to heat it up and assist it infuse extra strongly. The identical approach is within the medical writings attributed to Greek doctor Hippocrates who lived round 450-380 BCE.
The doctor Aretaeus, who was lively round 150 CE in what’s now trendy Turkey, wrote that daylight might remedy persistent circumstances of what he referred to as “lethargy” however we would recognise in the present day as despair:
Lethargics are to be laid within the mild, and uncovered to the rays of the Solar (for the illness is gloom); and in a relatively heat place, for the trigger is a congelation of the innate warmth.
Classical Islamic scholar Ibn Sina (980-1037 CE) described the well being results of sunbathing (at a time after we did not know in regards to the hyperlink to pores and skin most cancers).
In E book I of The Canon of Medication he mentioned the new Solar helped every thing from flatulence and bronchial asthma to hysteria. He additionally mentioned the Solar “invigorates the brain” and is useful for “clearing the uterus”.
It was generally arduous to inform science from magic
All of the methods of curing described to this point rely extra on the Solar’s warmth relatively than its mild. However what about curing with mild itself?
English scientist Sir Isaac Newton (1642-1727) knew you may “split” daylight right into a rainbow spectrum of colors.
This and plenty of different discoveries radically modified concepts about therapeutic within the subsequent 200 years.
However as new concepts flourished, it was generally arduous to inform science from magic.
For instance, German mystic and visionary Jakob Lorber (1800-1864) believed daylight was the most effective remedy for just about something. His 1851 e-book The Therapeutic Energy of Daylight was nonetheless in print in 1997.
Public well being reformer Florence Nightingale (1820-1910) additionally believed within the energy of daylight. In her well-known e-book Notes on Nursing, she mentioned of her sufferers:
second solely to their want of contemporary air is their want for mild […] not solely mild however direct daylight.
Nightingale additionally believed daylight was the pure enemy of micro organism and viruses. She appears at the least partially proper. Daylight can kill some, however not all, micro organism and viruses.
Chromotherapy – a approach of therapeutic based mostly on colors and lightweight – emerged on this interval. Whereas a few of its supporters declare utilizing colored mild for therapeutic dates again to historic Egypt, it is arduous to search out proof of this now.
Fashionable chromotherapy owes rather a lot to the fertile thoughts of doctor Edwin Babbitt (1828-1905) from america. Babbitt’s 1878 e-book The Ideas of Mild and Colour was based mostly on experiments with colored mild and his personal visions and clairvoyant insights. It is nonetheless in print.
Babbitt invented a transportable stained-glass window referred to as the Chromolume, designed to revive the stability of the physique’s pure colored power. Sitting for set intervals underneath the colored lights from the window was mentioned to revive your well being.
Indian entrepreneur Dinshah Ghadiali (1873-1966) examine this, moved to the US and invented his personal instrument, the Spectro-Chrome, in 1920.
The idea behind the Spectro-Chrome was that the human physique was made up of 4 components – oxygen (blue), hydrogen (purple), nitrogen (inexperienced) and carbon (yellow). When these colors have been out of stability, it precipitated illness.
Some hour-long classes with the Spectro-Chrome would restore stability and well being. By utilizing its inexperienced mild, for instance, you may reportedly support your pituitary gland, whereas yellow mild helped your digestion.
By 1946 Ghadiali had made round 1,000,000 {dollars} from gross sales of this gadget within the US.
And in the present day?
Whereas a few of these remedies sound weird, we now know sure colored lights deal with some sicknesses and problems.
Phototherapy with blue mild is used to deal with new child infants with jaundice in hospital. Folks with seasonal affective dysfunction (generally referred to as winter despair) may be handled with common publicity to white or blue mild. And ultraviolet mild is used to deal with pores and skin situations, resembling psoriasis.
At present, mild remedy has even discovered its approach into the magnificence business. LED face masks, with celeb endorsements, promise to battle zits and cut back indicators of ageing.
However like all types of mild, publicity to it has each dangers and advantages. Within the case of those LED face masks, they might disrupt your sleep.
