Objective: To investigate the effects of grounding on heart rate variability and stress.
Context: Grounding may help regulate the autonomic nervous system and reduce stress, but high-quality evidence is limited.
Methods Used: A randomized controlled trial of grounded sleeping (conductive sheets) versus sham grounding for 8 weeks in adults with elevated stress levels.
Data Collection: Measured heart rate variability, cortisol, and self-reported stress levels at baseline and biweekly.
Researchers' Summary of Findings
Impact on Health: Grounding significantly increased heart rate variability and reduced cortisol versus sham, indicating reduced stress and increased autonomic regulation.
Health Implications: Simple grounding techniques may improve autonomic function and resilience against stress. Larger studies on long-term cardiovascular impacts are warranted.
