We tend to forget the frequency of 7-8 Hz, which has been shown to have a healing effect on the body, and to help regulate the human body's electricity after flying on an airplane, or using wifi and bluetooth, or being surrounded by electronics, appliances and cell phone towers, and all these things that tend to deleteriously affect the electrical potential of ourselves.
Now, this 7-8 Hz frequency is actually located on the surface of our the Earth. That's right– our planet emits a natural frequency, a magnetic frequency, called the Schumann Resonance. And when you sleep on the Earth, as you would when you're camping, or when you go outside barefoot, it actually has a profound effect on your health and your emotions.
Ben Greenfield goes out of his way to get in touch with the earth for at least 10 minutes per day to take advantage of the benefits that comes from connecting with the Schumann Resonance.
Ben wears Earth Runners earthing sandals, which feature a copper plug and conductive laces, to reap the benefits of being grounded–even when footwear is required.
Ben Greenfield says:
There’s this company called Earth Runners, and they use this grounded conductive lacing system and copper plugs on the bottom of the sandals. They also sell grounding systems that you can use to outfit any shoe.
When you’re wearing these sandals, you’re actually grounded no matter where you’re at. There’s a stainless steel thread on the bottom of the lace, and a copper plug circuit on the bottom of the sole.
I own a few pairs of these things. I’m a huge fan of the concept of earthing shoes.
