This brings to mind a piece of advice I was given by my yogi that seems related.
Within yoga there are meditations that increase accessibility to the subtler bodies. During such meditations the body should not be in contact with anything metallic or electrically conducting material. If so, the body can be shielded by using either silk or wool.
A starting hypothesis could be that there are some sort of field shielding properties in textiles woven from fabric that come from living beings (sheep, silk worms).
But it may not be the fabric alone but also the geometry involved in the weaving that creates the shielding effect. I wonder whether sheep would as affected as other animals or by testing if there's a difference when wearing woven wool compared to just clumps of wool like when it's on the living sheep.
