cheers babes... you need a couple of digital hygrometers to regulate the humidity in the space you occupy... strangely, humidity can change rapidly... they are like $10 from the usual sources... not having a hygrometer is like driving without a speedometer! Its sad and revealing that top doctors don't know this, meanwhile obviously children should be taught this in order to maintain health... though we know "science"... create the problem, and come up with a fake solution!
