THE SUN'S RAYS HAVE DISINFECTING POWER
Many people do not know that the Sun's rays can do much to safeguard our daily health.
Several studies have shown that ultraviolet rays in particular, i.e. certain electromagnetic waves generated by the Sun, can deactivate bacteria, viruses, spores, fungi, mould and mites in a completely natural way.
This means avoiding the use of detergents and chemical solutions, with consequent benefits for the environment, health safety and economic savings.
ULTRAVIOLET RAYS. WHAT TYPES ARE THERE?
UVA, UVB and UVC ultraviolet rays. What are the differences in nature and in the laboratory?
Natural light contains various types of rays, from those we can see with our eyes to invisible ones like ultraviolet.
The latter in turn are divided into UVA, UVB and UVC rays.
UVA rays
These constitute about 95% of UV light and their irradiation is constant throughout the summer and winter, so we are always exposed to them during the day.
They promote the photo-oxidation of melanin and also affect cellular metabolism.
These rays increase the human immune response to infections and increase the number of antibodies present in the blood.
Massive exposure, on the other hand, may age the skin prematurely and lead to other harmful effects.
UVB rays
These constitute about 5% of UV light and their intensity varies according to different factors such as season, altitude, clouds and pollution.
They not only darken the skin, but also stimulate vitamin D production, activate melanocytes and increase keratin production.
Here too, excessive exposure can cause not only rash, but also more serious damage.
UVC rays
These are very useful in sterilization and due to their high energy are effective against all microorganisms. They do not reach the surface of the Earth because they are stopped by the atmosphere.
Recreated in the laboratory, these rays are able to deactivate pathogens and thus stop their uncontrolled growth.
UV RAYS AND THE SPECTRUM OF LIGHT INVISIBLE TO THE HUMAN EYE
Th UVC band of rays eliminates bacteria, viruses, fungi, spores, mould and mites by acting directly on their DNA, destroying it and blocking reproduction and multiplication.
In other words, microbes do not withstand treatment with UVC rays. This has the great advantage that it is completely ecological compared to other products used for the same purpose.
In light of this, it is clear that UVC rays are very different from UVA and UVB rays.
Their frequencies, which are not perceived by the human eye, have long been used successfully to disinfect water, air and surfaces.
Safety, effectiveness, and environmental sustainability are the main strengths of sterilization systems using UVC technology.
UVC RAYS, BECAUSE THEY ARE DIFFERENT FROM OTHER RAYS
Drawing inspiration from nature, we have transformed them into a technology applicable to everyday use.
SAFETY: UVC-based disinfection, especially in the food, pharmaceutical and healthcare sectors, proves to be an environmentally friendly, cost-effective system.
EFFECTIVENESS: UVC rays are considered an effective solution for sanitation.
Organizations worldwide, such as the Italian National Health Institute, believe that UVC-based technology is suitable for eliminating a wide variety of viruses, including those belonging to the dreaded SARS (COVID) family.
The ISS COVID-19 report is clear: "UVC radiation has the ability to modify the DNA or RNA of microorganisms by preventing them from reproducing and inactivating 99.99% of the influenza virus in aerosols."
The virucidal and bactericidal action of UVC rays has been demonstrated in studies on MHV-A59, a rodent virus similar to MERS-CoV and SARS-CoV-1.’
Further encouraging opinions in line with this report have come from scholars at Columbia University, who are constantly engaged in testing the UVC band against SARS-CoV-2, offering interesting implications for our future.
UVC TECHNOLOGY ELIMINATES CONTAMINANTS IN SECONDS
Drawing inspiration from nature, we have transformed them into a technology applicable to everyday use.
The germicidal action is very high and targeted since it acts directly on the DNA of contaminants, be they bacteria, viruses, allergens, or other pathogens harmful to humans.
The destruction of DNA inhibits the possibility of reproduction, so the microorganisms subjected to UVC rays ultimately have no chance of survival.
When it comes to health and safety, a comprehensive approach must be adopted.
Treatments using UVC rays guarantee thorough hygiene and protection in all situations without having to rely on any chemical detergents or other polluting products.
HOW DO UVC RAYS ELIMINATE MICROORGANISMS?
No microorganism can withstand UVC rays.
What, specifically, is sanitation?
Sanitation is nothing more than the combination of two distinct and effective UVC ray actions that definitively eradicate contaminants.
UVC rays both sanitize and disinfect.
Today UVC rays are used to sanitize air and surfaces in many sectors, for example, the food and pharmaceutical industries.
UVC rays are also used in hospitals to prevent contagion and bacterial transmission between employees and patients.
In short, there are no limitations to UVC technology.
This is why we have decided to use these rays in a new system intended for clothing shops and elsewhere.
What’s more, UVC-based treatments also eliminate unpleasant odours due to microorganisms.
World-renowned entities and organizations recommend UVC sanitation as a safe, effective and environmentally friendly solution.
Some contaminants are also particularly sensitive to treatment, which has already been tested on several viral strains, including coronavirus.
The WHO, EPA, CDC and ASHRAE are just some of the organizations that recommend the use of UVC rays to sanitize water, air and surfaces.
CONSTANTLY EVOLVING RESEARCH AND EXPERIMENTATION
New scientific discoveries
COVID ‘can be destroyed simply with light’.
This is the result from researchers at the University of Hiroshima, who have made a very interesting discovery at this very moment in history.
The team of scholars led by Professor Hiroki Kitagawa found that UVC light effectively counteracts SARS-CoV-2 on contaminated surfaces and in closed environments, remaining completely harmless to people.
The results of the study, entitled Effectiveness of 222-nm ultraviolet light on disinfecting SARS-CoV-2 surface contamination, were published in the American Journal of Infection Control.
Through in vitro tests, researchers were able to determine that as much as 99.7% of the SARS-CoV-2 virus strain was destroyed after about 30 seconds of exposure to a beam of UVC light.
