The research explores how grounding influences inflammation, immune responses, wound healing, and chronic diseases. The study proposes that grounding leads to measurable changes in white blood cell concentrations, cytokines, and molecules involved in inflammation. It suggests that grounding may alleviate pain, modulate immune cell numbers, and affect circulating chemical factors related to inflammation. The central hypothesis suggests that connecting the body to the Earth spreads free electrons, creating antioxidant effects. Additionally, the study explores the potential of Earth-derived electrons in preventing or resolving "silent" inflammation, offering insights into inflammatory responses, wound healing, and immune system functioning. Grounding also shows promise in improving sleep, cortisol rhythm, pain reduction, stress alleviation, autonomic nervous system modulation, heart rate variability, wound healing, and blood viscosity. 

A preliminary study involving 12 subjects experiencing pain and sleep difficulties demonstrated normalized cortisol profiles, improved sleep, and reduced pain and stress levels during an 8-week grounded sleep intervention.
