Earthing or Grounding is a concept where one spends time barefoot on moist soil or grass or wears an electrical connection while sleeping connected to a electrical ground source. It is supposed to help the body normalize free radicals. Claims are that it can help with insomnia, reduce inflammation, help the immune system and some other health problems.

Free radicals are known to cause health issues. Anti-oxidants are one way to reduce free radicals.

Amazon and other online sources sell earthing kits, $30 or more, depending on the version. It has some science behind it, including some blind studies. The cost is cheap enough to try it with minimal risk. The kits either use an EKG patch or wrist or ankle bands connected by a wire to the third prong (only the third prong, it is not energized) of a grounded electrical outlet.

I found this while looking into the Fisher Wallace Stimulator that some use for insomnia. Google appears to have targeted me for Fisher Wallace Stimulator ads since I googled it last week.
