From the Research
Grounding, also known as earthing, has been shown to have potential health benefits, including reducing inflammation and improving sleep, as evidenced by a 2023 study published in the Biomedical journal 1. The primary evidence comes from small-scale studies suggesting that direct physical contact with the Earth's surface may reduce inflammation, improve sleep, decrease pain, lower stress, and normalize cortisol rhythms. These studies propose that the Earth's negative electrical charge may neutralize free radicals in our bodies, acting as a natural antioxidant. The proposed mechanism involves electrons from the Earth flowing into our bodies when we make direct contact with soil, grass, sand, or water, potentially counteracting the positive charge of free radicals. Some research indicates that grounding may affect blood viscosity, heart rate variability, and immune responses, as noted in a 2023 study published in the Biomedical journal 2. However, most health claims about grounding lack robust scientific validation from large, well-controlled clinical trials. The practice is simple to implement by walking barefoot outdoors, sitting or lying on the ground, or using conductive systems like grounding mats or sheets that connect to the Earth. While generally considered safe, grounding should complement rather than replace conventional medical treatments for serious health conditions, as suggested by a 2020 review published in Explore (New York, N.Y.) 3. Key benefits of grounding include:
- Reducing inflammation
- Improving sleep
- Decreasing pain
- Lowering stress
- Normalizing cortisol rhythms It is essential to note that more extensive studies are warranted to fully understand the effects of grounding on human health, as stated in a 2015 study published in Psychological reports 4. In contrast, a 2019 study published in Neuropsychopharmacology did not provide relevant evidence for grounding 5. Overall, the current evidence suggests that grounding may be a useful adjunctive therapy for reducing inflammation and improving overall health, but more research is needed to fully establish its benefits 1, 2, 3.
