Re: What to do about PMS...

 Earthing is connecting yourself to the earth.   The earth has a magnetic field and an electrical charge that we are supposed to be in contact with

The benefits of reconnecting were discovered by an electrician who knew that cable systems did not work well if not grounded to the earth due to all the interference.

He tried grounding himself, slept better, less joint pain and many other benefits.  Here is a book on Amazon

You can get sheets, ankle straps, mouse pads, foot mats, etc.  One wire plugs into the little round electrical hole in your receptacle. The “3^rd hole” of your receptable is connected to the earth

There are starting to be more and more studies on Pubmed
