I'm posting this in the forum that a) seems most appropriate, and b) likely to get the fewest number of views. But I'm trying to play by the rules, so I'll take my chances. Here's the thing: in a seemingly endless search to assist my better half with her insomnia problem, we came across the concept of grounding (the word Earthing is a trademarked term, meant for commerce, so I'm going to stick with the word indicating what is actually happening). Many of you are probably familiar with it; I was not until just recently. But the more I read about it, the more intriguing the idea gets, for this reason: My barefoot running experience, blisters notwithstanding, has been revelatory in so many ways. Yet it leaves me wondering: is all this (for lack of a better term) positive energy due solely to the improved running form, cadence, and running style, or is there something else going on? For instance, that tingly feeling that I often get in my feet and legs after a run -- is that merely nerve-ending stimulation and capillary opening, or is there something else happening? Hence, when I came across the grounding idea, it caught my attention, because it seemed to answer those questions. Could this be the reason, for instance, why running with (close to) exactly the same form in minshoes doesn't result in the same sensory experience as the same run done bare? So, I'm asking for any experience any of you have with grounding. Have you done it during sleeptime? Do you know others who've had experience, good, bad, or indifferent, with it? If you have electrical engineering in your background, can you explain why the concept is full of horseshit, if you believe it is? Spare me your skepticism; I have enough of that of my own and can't carry the burden of yours. No fair judging without prior investigation, either. I'm looking for genuine experience with grounding, even if that experience results in your conclusion of snake-oil-equivalency because it didn't work for you.
