Schumann Resonator

Kind of OT, but...

Has anyone using these devises (especially in multiples) noticed a change in their bowel movements and/or blood pressure?

Just curious as having researched the device/mechanism these health issues popped up.

More interested in BP, but BM's are always fun reading as well.

Scratch what I said above about the phase of the resonator interacting with the earths natural Schumann resonance. That refers to a EMR frequency. Sound also has frequency and wavelength but is a different kind of wave (sound) altogether. I’m assuming these devices emit sound waves at the Schumann frequency not electro magnetic radiation EMR. 
In  either case however  the device is the source of whatever it is that it may emit so one would expect the results to vary significantly with distance from transmitter ie the device to the sensor ie the brain and ears.

Schumann frequency is apparently a popular marketing concept for herbal medicine but I am not able to find anything to substantiate that as a valid thing. The most common conclusion appears to be that it is merely a marketing ploy when it comes to selling health products.

I found a science article from Japan that said it reduces blood pressure.

The product info on Amazon is interesting. Reads like written in broken English. It says it does not emit sound. That would leave EMR as what is emitted by default. That is what the earths Schumann resonance is based on. So who knows? It’s a mystery. Try it and see if one must. It’s a good kibbutz that does not cost much at least.
