Reducing Stress Naturally: How Grounding Influences Psychological Well-being and Cortisol Levels

Abstract

Objective: This study examines the effects of grounding on psychological stress reduction and cortisol levels in adults under chronic stress.

Context: Grounding or earthing refers to direct contact with the earth's surface electrons, theorized to promote physiological and psychological well-being. Despite anecdotal claims of its stress-reducing benefits, there is a paucity of empirical research validating these effects.

Methods Used: A randomized, double-blind, placebo-controlled trial involved 100 participants with clinically assessed chronic stress. Subjects were assigned to either a grounding group, engaging in daily grounded walking (barefoot on grass) for 30 minutes, or a control group performing the same activity with insulated shoes. The 8-week intervention measured subjective stress levels using the Perceived Stress Scale (PSS) and physiological stress via salivary cortisol samples collected at four time points throughout the day.

Researchers' Summary of Findings: The grounding group exhibited a significant decrease in PSS scores and a normalized cortisol daily rhythm compared to the control group. These results suggest that grounding may mitigate psychological stress and modulate cortisol levels, possibly through the reduction of systemic inflammation.

Health Implications: Grounding offers a simple, accessible intervention for stress management, with potential benefits for cortisol regulation and overall stress resilience. Further research is encouraged to explore grounding as part of holistic approaches to stress and mental health.
