In winter or all year round, there is a simple way to do 'Grounding', it is to carve out a small surface of square galvanized wire fencing, connect it to a wire on the outside, and a steel rod planted in the ground near the house. You can put this pin in your bed, under your legs, or under your back if you have back pain.

Fascinating.

God created earth and greens for us on day 3. He said it was good: Genesis Chapter 1 Close your eyes for imagery

Take a multimeter and check the ground voltage. God created everything we need to live on earth. God created nature. In principle, if you love God, you also love His creation.
