We are electrical beings.  I recommend walking barefoot on grass or soil or the beach… but it’s not always convenient on a daily basis.  Here’s a solution: get a grounding sheet or mat. 

www.groundology.co.uk

produces these and more and you can watch videos, films and interviews from their website.
Being earthed daily (or nightly with a grounding sheet or blanket) reduces pain, swelling, blood pressure, promotes good sleep and improves energy.
