Putting your bare feet on natural soil, like grass or sand. Cement works too, but asphalt does not. Wet/damp grass/sand works best.

Supposedly, it lowers inflammation, blood pressure, changes your brainwaves, helps against jet lag, and more.

Sometimes it’s also called #grounding 

 Ummm interesting, why it doesn't works on asphalt ? It's isolating like rubber ? 

 Exactly 😉
