The research on grounding
Grounding research is early, and it's mixed. Some studies report changes in measurements like blood viscosity, cortisol, or self-reported sleep and mood; others are small pilot studies that haven't been repeated at scale. We're not going to inflate what's here. Below is what's been published, grouped by topic, with a link to each original study so you can read the methods and conclusions yourself.
Sleep & stress
- Ghaly & Teplitz (2004), Journal of Alternative and Complementary Medicine — measured cortisol levels and self-reported sleep, pain and stress in participants who slept grounded over an 8-week period. Read on PubMed
- Lin et al. (2022), pilot study — tracked sleep-quality scores (PSQI) in adults with mild Alzheimer's disease before and after a period of grounding. Read on PMC
- Chevalier (2010) — measured pulse rate, respiratory rate, blood oxygenation, perfusion index and skin conductance in participants during grounding sessions. Read on PubMed
- Chevalier et al. (2011), Physiologic Processes — a review summarizing physiological measurements (skin conductance, EEG, blood flow) reported across earlier grounding studies. Read on PMC
Muscle recovery
- Brown, Chevalier & Hill (2010), JACM — pilot study comparing delayed-onset muscle soreness (DOMS) in grounded vs. ungrounded participants after exercise. Read on PubMed

Blood & circulation research
- Chevalier, Sinatra, Oschman & Delany (2013), JACM — measured blood viscosity, a factor studied in cardiovascular health, before and after grounding. Read on PubMed
- Chevalier, Patel, Weiss, Chopra & Mills (2019), JACM — measured blood viscosity in participants doing yoga on a grounded yoga mat. Read on PubMed
