>>76262796 (OP)it's not rocket science - we walk in plastic clothing, in insulating shoes on insulated ground, ofc we loose electric charges
studies found that people that do electric grounding (for example touching the heating pipe (which is electrically grounded, has a huge capacity and is a great conductor)) are significantly better at healing and has less systemic inflammation on average
obv the efficiency of barefooting may vary greatly depending on soil type, hydration levels, etc. but the concept in itself is easy to comprehend and quite straightforward
pic related is not really a good answer because the chlorine in water is going through reduction (steals electrons) so eventhough water goes through electrically grounded systems and (by having electrolytes) is a fairly good conductor, regular (prepared) tap or swimming water is not good for this use
