Sunlight outside the body, as regards Covid-19, may be a rather new and intriguing concept. Yet, we have alluded to it briefly in a previous blog. Research from the Department of Homeland Security (DHS) corroborates the idea that direct sunlight rapidly kills the Covid-19 virus. The researchers tested effects of sunlight on Covid-19 viruses in aerosols, suspensions of solid particles or liquid droplets in air. These aerosols represent a potential route of disease transmission, and in this case, transmissions of Covid-19 viruses. Therefore, if sunlight exposure accelerates the decay of these viruses, it prevents an avenue of human-to-human transmission. Thus, breathing in of viruses coughed, sneezed, or even breathed out by others (as in saliva) ceases to be problematic. Sunlight outside the body inactivates the viruses due to decaying them.
The bottom line regarding outside sunlight and Covid-19.
Because of this research, it we know that without sun exposure, the time required to decay the virus was 125 minutes. With direct sunlight, the time ranged from 6 to 19 minutes, according to the intensity of the exposure. That is a profoundly significant change, and is probably why Florida fared so much better than New York, with Covid-19.
Hence, we have shown that sunlight is a two-edged sword; sunlight outside the body helps to halt transmission of the disease. Sunlight’s ability to produce vitamin D in the skin (inside the body) prevents the cytokine storm, which is how Covid-19 kills.
People have long believed that sunlight was the best disinfectant.
First, the German microbiologist Robert Koch, who isolated TB bacteria in 1882, showed that sunlight had disinfectant qualities; it destroyed tuberculosis bacteria. In addition, even earlier, in 1877, other researchers discovered that sugar water left in the shade became cloudy, indicative of bacterial growth. However, if exposed to sunlight, it remained clear. Dr. Zane Kime, in his book, Sunlight Could Save Your Life, wrote that history. In addition, he also reviewed the results of research conducted between 1886 and 1909. Most noteworthy, it showed that the following bacteria succumbed to ultraviolet light: Anthrax, plague, streptococci, tubercle bacillus, cholera, staphylococcus, colon bacillus and dysentery bacillus. Nevertheless, most people forgot sunlight with the advent of antibiotic drugs, but now the interest has returned. (Cited in Kime, Z. Sunlight Could Save Your Life.

So, please realize that the master disinfectant, sunlight, is the best in the world. Thus, it is ready to do battle with the worst the Covid-19 virus can throw at the human body. Get your share of non-burning sunlight and survive this pandemic. For more information, visit sunlightinstitute.org and read the book, Embrace the Sun.
