Effects on Sleep and Cortisol Rhythm:
A study published in the Journal of Alternative and Complementary Medicine examined the effects of grounding on sleep and circadian cortisol profiles. The 8-week trial involved 12 subjects with sleep problems and pain. Results showed:
- Normalization of cortisol profiles
- Improved sleep quality
- Reduced pain and stress levels
The researchers concluded that grounding during sleep produces measurable changes in cortisol levels, which in turn improve sleep, pain, and stress.

Sleep Quality in Patients with Mild Alzheimer's Disease:
A 12-week placebo-controlled study published in Healthcare (Basel) in 2022 investigated the effects of grounding on sleep quality in patients with mild Alzheimer's disease. The study found:
- Significant improvement in sleep quality (measured by PSQI scores) in the grounded group compared to the sham-grounded group
- 62.5% of subjects in the grounded group showed improved sleep quality vs 14.3% in the sham-grounded group
- No significant changes in anxiety or depression scores
-
Effects on Pain:
A systematic review of studies on grounding and pain found mixed results:
- Two studies showed a reduction in pain with grounding
- One study by Ghaly et al. reported that 10 out of 12 subjects experienced decreased pain when sleeping grounded
- Brown et al. found that pain ratings in the grounded group were at least 80 percentage points lower than the placebo group
- However, one study by Chevalier et al. did not show significant differences in pain between grounded and placebo groups

Effects on Inflammation and Immune Response:
A comprehensive review published in the Journal of Inflammation Research in 2015 found that grounding:
- Significantly reduces inflammation
- Enhances immune response
- Accelerates wound healing
- Reduces pain and swelling
- Improves recovery from illness or injury
The study suggests that grounding helps regulate immune system activity and improves overall resilience to infections.
