Hi, guys:
I'll reply to both threads here.
It is very nice to hear that some parents understand smth about healthy living. When children drink water without rat poison added to it, they develop naturally. The only victims are the medical profession as well as those who manufacture health-care products, as they have less customers.

Regarding the bedding, I have to do some reading about BFR. But except winter, I keep windows open, I use Japanese-style heating - extra clothing. But so far the rationale for this was to minimize the effects of radon.
Some people I know never open a window even in summer!
Best regards:
Oleg
