Abstract Summary

Objective: This study investigates the role of grounding in reducing stress and improving sleep quality in individuals with insomnia.

Context: Grounding, also known as earthing, involves direct skin contact with the Earth's surface. It is believed to neutralize free radicals and reduce stress. This research aims to assess the effectiveness of grounding in reducing stress levels and improving sleep quality in individuals with insomnia.

Methods Used

Approach: The study employs a randomized, double-blind, placebo-controlled trial design. Participants included individuals aged 20-50 with diagnosed insomnia. They were assigned to either the grounding group (using grounding sheets) or a placebo group (using identical but non-grounding sheets) for six weeks. Stress levels and sleep quality were monitored throughout the study.

Data Collection: Measurements included assessments of cortisol levels, heart rate variability (HRV), and self-reported sleep quality using the Pittsburgh Sleep Quality Index (PSQI) at the start, three weeks, and six weeks. The results from the grounding group were compared to those from the placebo group.

Researchers' Summary of Findings

Impact on Health: The study found that grounding significantly reduces stress and improves sleep quality in individuals with insomnia. Participants in the grounding group showed lower cortisol levels, improved HRV, and better sleep quality scores compared to the placebo group.

Health Implications: Grounding can be a valuable non-invasive strategy for reducing stress and improving sleep quality in individuals with insomnia. This suggests potential benefits for overall health and well-being through regular grounding practices.
