There’s definitely something to it in the sense of mechanistically conducting electricity. Sometimes I feel an unmistakable subtle zap. But I can’t say I’ve used it very regularly because when I wash the pillow case I don’t put it back on until it makes its way to the clean laundry and the one it got replaced by is due for a change. So I use it intermittently and if I can call the times I don’t use it my cross over phase, I can’t say I notice anything positive or negative so I wouldn’t bother. Perhaps it’s having physiological effects that I just can’t detect but I doubt they’re large.
