Earthing

TECHNIQUE — Take off your shoes and stand or walk barefoot on grass, sand or soil. Slow down and feel the earth beneath your feet.

THE SCIENCE — Direct contact with the ground electrically connects the body to the Earth's surface. The Earth also has natural electromagnetic activity, including the approximately 7.83 Hz Schumann resonance. Small studies of earthing have reported possible effects on sleep, stress and physiological measures, although research remains limited and hasn't established that 7.83 Hz itself produces these effects.
