Abstract
Oxford Academic - The Journal of Infectious Diseases
Previous studies have demonstrated that SARS-CoV-2 is stable on surfaces for extended periods under indoor conditions. In the present study, simulated sunlight rapidly inactivated SARS-CoV-2 suspended in either simulated saliva or culture media and dried on stainless steel coupons. Ninety percent of infectious virus was inactivated every 6.8 minutes in simulated saliva and every 14.3 minutes in culture media when exposed to simulated sunlight representative of the summer solstice at 40oN latitude at sea level on a clear day. Significant inactivation also occurred, albeit at a slower rate, under lower simulated sunlight levels. The present study provides the first evidence that sunlight may rapidly inactivate SARS-CoV-2 on surfaces, suggesting that persistence, and subsequently exposure risk, may vary significantly between indoor and outdoor environments. Additionally, these data indicate that natural sunlight may be effective as a disinfectant for contaminated non-porous materials.
Over and over we've been told "to stay home" but increasingly, it is being shown that this virus tends to spread faster and easier indoor than outdoor.
So 'stay at home' should be replaced with 'stay outdoors in the sunshine', of course with the caution to use sunscreen and keep your distance from others as viruses can still spread from coughs and sneezes. 
Additional Information
Researchers led by Shanna Ratnesar-Shumate from the National Biodefense Analysis and Countermeasures Center, Operated by BNBI for the US Department of Homeland Security, have found that simulated sunlight could effectively kill severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that is responsible for the worldwide COVID-19 pandemic. The study titled, “Simulated Sunlight Rapidly Inactivates SARS-CoV-2 on Surfaces,” was published in the latest issue of the Journal of Infectious Diseases.

Coronavirus Pandemic Update 56:
What is “Forest Bathing” & Can It Boost Immunity Against Viruses?
COVID-19 Update 56 with Roger Seheult, MD of https://www.MedCram.com
A series of joint studies from Stanford University School of Medicine and several medical schools and institutions in Japan demonstrated that exposure to “phytoncides” released by trees and plants may boost immunity by increasing natural killer cell quantity and activity among other effects. Dr. Seheult illustrates how these studies were conducted as exposure to forests (forest bathing) may fall into the category of additional things we can do (and that don’t cause harm) to potentially help prevent viral infections such as COVID-19.

THERAPIE IM GRÜNEN Wie Wald auf unsere Gesundheit wirkt
Das aus Japan kommende "Waldbaden" und der Trend zur Nutzung der Wälder für Therapien sind in Europa bereits vielfach etabliert. Wer in einer sehr urbanen Umgebung lebt, entwickelt auch eigene Zugänge zur Natur. "Waldbaden", das sich auch in Europa als Trend etabliert, ist ein gutes Beispiel dafür. Der Ansatz resultiert aus der von großen Städten geprägten Kultur Japans. ...... MEHR LESEN

Hilfe aus dem Wald: Bäume als Medizin Scientists Claim That Quantum Theory Proves Consciousness Moves To Another Universe At Death13/4/2014 
A book titled “Biocentrism: How Life and Consciousness Are the Keys to Understanding the Nature of the Universe“ has stirred up the Internet, because it contained a notion that life does not end when the body dies, and it can last forever. The author of this publication, scientist Dr. Robert Lanza who was voted the 3rd most important scientist alive by the NY Times, has no doubts that this is possible. - See more at: http://xposethereal.com/scientists-claim-that-quantum-theory-proves-consciousness-moves-to-another-universe-at-death.html 
Every now and then, a simple yet radical idea shakes the very foundations of knowledge. The startling discovery that the world was not flat challenged and ultimately changed the way people perceived themselves and their relationships with the world. “If the earth were really round,” it was argued, “Then the people at the bottom would fall off.” For most humans of the 15th century, the notion of Earth as ball of rock was nonsense. The whole of Western natural philosophy is undergoing a sea change again, forced upon us by the experimental findings of quantum theory. At the same time, these findings have increased our doubt and uncertainty about traditional physical explanations of the universe’s genesis and structure.
Biocentrism completes this shift in worldview, turning the planet upside down again with the revolutionary view that life creates the universe instead of the other way around. In this new paradigm, life is not just an accidental byproduct of the laws of physics. |
