Safer UV Light Kills Virus That Causes COVID-19, Study Reveals


The Coronavirus outbreak has affected the world and there has been a change in the “normal” world we were all used to. Many families have lost their loved ones, economies of nations have crumbled and many have been left bitter. A recent study revealed that safer UV light kills the virus that causes COVID-19.

Who would not want a perfect antidote for Coronavirus? We all want to go back to normalcy and enjoy having mutual relationships with families, friends, and loved ones. Researches have been ongoing across the globe as to what the remedy to Coronavirus is. A recent study shows that researchers have offered first proof, which says that ultraviolet-C light having a 222 nm wavelength can effectively kill the virus that causes COVID-19.

It is revealed that the ultraviolet C light is quite safer and without harm when used in presence of humans and cannot harm the living cells in our eyes and skin. It is interesting to note that this is the first study globally that verifies the ultraviolet C light potency against the SARS-CoV-2.

The study was carried out by Hiroshima University researchers and it found out that safer UV light can kill the Coronavirus effectively. Hiroshima University conducted an in vitro experiment revealing that 99.7% of the viral culture of SARS-CoV-2 was terminated after a 30-second exposure to 222 nm ultraviolet-C irradiation at about 0.1mW/cm2.

As a result of this study, many laboratories in the university have begun to carry out researches on COVID-19 under the “Hiroshima University CoV-Peace-Project”. The research has been duly supported by the Japan Agency for Medical Research and Development (AMED).

Some studies that include 222 nm ultraviolet C, which is also widely called Far-UVC, have only considered its potency in killing seasonal Coronaviruses, which have a similar structure to the SARS-COV-2. But with safer UV light, the virus that causes COVID-19 can effectively be killed.
