Fresh Air and Sunshine

It is strange, but now sadly predictable, that in the critical heat of a crisis, common sense is always the first to leave. Watching it all unfold before your eyes is so frustrating, especially when someone comes along with the results of research which seems to prove what your grannie could have told you long ago.  

Today we had the results from a study in a scientific journal, the “Journal of Photochemistry and Photobiology”, which find, surprise, surprise, that sunlight can kill the virus in about 30 minutes and being cooked up inside isn’t a great idea.

“Forcing people to remain indoors may have increased contagion among same household dwellers and among patients and personnel inside the same hospital or geriatric facilities.  In contrast, healthy people outdoors, receiving sunlight could have been exposed to a lower viral dose with more chances for mounting an efficient immune response.”

Now I cannot pretend for a minute that I know anything about the subject and there will be other scientist, especially those who favoured the lock-down method of combating the virus, who would take the opposing view, but when the science is not at all clear, I guess it is best to go with common sense.

One thing I do know a bit about is building. Yesterday I read about a study carried out by the Ministry of Housing responsible for building regulations in England. It came up with the finding, again surprise, surprise, that living in a hermetically sealed environment can seriously damage your health. Now I remember being at a seminar when the new regulations over air leakage in new buildings in Scotland were introduced. These define how air tight a new home should be, with strict tests to ensure that a building is compliant. I felt uneasy about it at the time and couldn’t see how this sat easily with the other important requirement, that a dwelling should be properly ventilated. Now we learn that there are serious risks to health directly associate with this regulation. It causes overheating in houses leaving people “stewing in their beds” with consequential “loss of productivity, domestic abuse and even deaths”. The push towards air tightness was driven, of course, by the need to be energy efficient and this is understandable, but the side effect doesn’t seem to have been properly considered.

It is astonishing how the focus on one specific objective seems to create a blindness to other equally important factors. The virus is racing through the population so we lock people in their homes to prevent its spread, not having considered that maybe that action might actually make matters worse. Air leakage from dwellings contributes to heat loss, energy inefficiency and ultimately global warming so we hermetically seal our homes, not having considered that maybe the consequential loss of ventilation might be a really bad thing.

I genuinely wonder how this happens. Is it because people become so locked into their own professionally specialised bubble that they can’t see the wood for the trees.  Is it because the way politics works, the immediate threat or issue, the one the media has locked on to, has to be the one we fixated on and it gets all the attention and resources? Or is it quite simply that, somewhere along the line, we have lost that virtue that we used to call common sense?
