Earlier quoted context omitted.
Do you need an explanation of why the touch of another human would be obviously beneficial? I find walking on bare dirt or earth to be similar. I think experiencing is believing.
I think the need for an explanation/citation scales relative to how common a given anecdotal experience is. I’ve spent plenty of time walking barefoot outside but apparently have not experienced what people here are claiming. Not saying no one can/does, but at the very least the experience doesn’t seem to be universal.
>but apparently have not experienced what people here are claiming
Or you did have experience it just did not notice. The problem with experiential comparisons is that different people have different levels of sensitivity and attention. So just because you didn't feel it consciously doesn't mean you did not benefit from it.
