"Masks don't work." - not so much, COMPARED WITH RESPIRATORS!
And of course, depending upon your definition of "work" and for what purpose...
But! Hear from the pros Dr. Mike Osterholm (#PublicHealth #InfectiousDisease) and Dr. Lisa Brosseau (#IndustrialHygiene) regarding recent research on it!
Masking is not fun or convenient. That is clear.
The #HierarchyOfControls from #IndustrialHygiene will also tell you that masks are our worst defense, but that doesn't mean they don't help.
We must invest in affordable solutions to increase #IndoorAirExchange, and with plans to retrofit existing buildings.
The challenge: #ClimateChange makes the need for temperature management indoors even more important, with more extremes and limiting combustible sources.
How can we do it? π€
