How does grounding exchange electrons?

The concept of grounding, also referred to as "earthing," involves the exchange of electrons between the body and the Earth. Andrew Huberman discusses grounding and suggests that it potentially improves mental and physical health through the exchange of electrons with the Earth's surface. He notes that rubber-soled shoes may block some of this electron exchange. The theories about grounding are tied to the tactile sensation of touching the Earth as well as this electron exchange, although the scientific evidence for grounding remains inconclusive and not robustly supported by high-impact scientific publications 1.
