Nonsense.
The black paint must be grounded, and the grounding brings dirty electricity into the rooms.

The high frequencies may be shielded, but the low frequencies, especially from 5kHz up to 10-30MHz can play a destructive part on your body.

Tin foil also shields against the nescessary cosmic rays, we need for living.

Charles,

Regarding not blocking the cosmic rays we need for health:  I have ceiling and most of 3 walls shielded - is leaving the fourth wall unshielded (and 1/2 of one of the other walls) enough to allow the cosmic rays that we need for health into the room?  The unshielded wall, which does not allow much RF in, so feel safe leaving it unshielded for RF purposes., is west-facing, if that makes any difference (I am in coastal California).
 
Thank you for any info, Ellen

Either way, I'd gladly be a guinea pig to test the efficacy of such a place.
