Grounding/Earthing for Stress Relief

Research suggests that grounding or earthing — making direct physical contact with the Earth's surface or using conductive systems indoors — may be associated with reductions in stress-related markers such as cortisol levels and self-reported stress, pain, and sleep disturbances. The available evidence includes a small pilot study reporting improved cortisol rhythms and subjective wellbeing after eight weeks of grounded sleep, a narrative review synthesizing roughly 20 studies in support of broad health benefits, a speculative theoretical paper proposing nervous system mechanisms, and a 2025 review examining grounding's potential relevance to Alzheimer's-related pathology. Studies indicate a consistently supportive direction across these publications, but the overall body of evidence is quite limited — comprising small samples, no large randomized controlled trials, and several papers written by researchers who are themselves proponents of the practice, which introduces the possibility of bias. Readers should be aware that grounding remains outside mainstream clinical medicine and that stronger, independently conducted trials would be needed before firm conclusions about its effectiveness for stress relief can be drawn.
