Is there anything that the general population can do to prevent themselves from getting #Covid-19, apart from the basic steps like social distancing, masks and handwashing?
Yes, says a new study done by two researchers formerly with the US FDA and US Army, and appearing in the journal ‘Photochemistry and Photobiology’. Their study says that hard midday sunlight in summer season across the world can destroy 90% of the Covid-19 viruses in just 34 minutes, from surfaces that have been coughed or sneezed upon. The ultraviolet type B (UVB) rays in such sunlight is said to be destroying the virus.
Now, isn’t that great news? Yes, but more than that, I want you to focus on the macro picture unravelled by such studies. Interestingly, there were competing studies earlier that claimed sunlight won’t help. My take is that, it is always better to look at the macro picture.
Plain common sense tells us that strong sunlight should be germicidal in nature. Let the studies come up with the finer details. But don’t miss the macro picture. A little bit of sunlight has always been good for us, not just by this UVB action, but in numerous known and unknown ways.
