Okay I may be completely reaching out here. But here are few of my experiences.
Few days back I overate and while sleeping sideways I put the phone speaker towards my stomach. Believe me I was feeling normal in about 20 minutes. But when I used it near my ear, it felt less not a lot but less effective.
Same thing I tried while I was having stomach pain few days back, I put on immunity booster. And instead of putting the phone next to me I placed it inside my blanket making it face my stomach directly. Trust me it was miraculous.
Yet another example when I was overdrunk few days back. Low volume. Put it in same position. Couldn’t even listen to the alcohol metaboliser, but my stomach was reacting to it in a positive manner.
So maybe targeting the organ produces little bit better results? Or am I just dreaming?
Now I know it’s not always possible to do it. But maybe give it a try. Lol
