Grounding / Earthing
Grounding / Earthing is classified as a nature-therapy practice and has been examined in relation to possible changes in symptoms and broader health. The overall picture remains unsettled: some findings come from clinical research, while other proposed effects are supported only by anecdotal reports or theoretical reasoning.
Grounding / Earthing is a nature-therapy practice.
Overview
Grounding / Earthing is classified as a nature-therapy practice and has been examined in relation to possible changes in symptoms and broader health. The overall picture remains unsettled: some findings come from clinical research, while other proposed effects are supported only by anecdotal reports or theoretical reasoning. Clinical research covers more than one outcome area, but the strength and type of support varies by claim, so a finding in one area cannot establish benefits across the practice’s other proposed uses. Overall, the available evidence does not establish Grounding / Earthing as a way to improve health or manage a condition.

How to read the evidence
Evidence tier — overall strength of the evidence for the whole compound
- StrongWell established — backed by strong, consistent human research.
- ModerateSome genuine support, but mostly from small or lower-quality studies. Promising, not proven.
- PreliminaryEarly-stage evidence — a promising hypothesis, not an established effect yet.
- LimitedVery limited evidence — treat this as a hypothesis, not proof.
- InsufficientNot enough good evidence to draw conclusions yet.
Certainty — how sure we can be that the effect is real
- Very highVery sure — strong, consistent evidence
- HighFairly sure — consistent evidence from good studies
- MediumModerately sure — new studies could change this
- LowNot sure — little or mixed evidence
- Very lowVery unsure — almost no usable evidence
Source — where the data comes from
- Meta-analysisPooled analysis of many trials — the strongest evidence
- RCTRandomized controlled trial — a strong human study design
- ClinicalA human clinical study
- Reference knowledgeFrom general health-science or pharmacology references, not a study of this exact claim
- Animal researchStudied in animals, not humans
- Community reportsAggregated user reports — anecdotal signal, not evidence
- TheoreticalMechanism-based reasoning, not yet tested
Study grade — quality of each underlying study (A best, D weakest)
- AHigh-quality — strong, consistent human trials
- BGood — solid evidence with some limitations
- CModerate — limited, small, or mixed-quality studies
- DWeak — preliminary, indirect, or animal-only
Confidence — how strongly the sources back a finding
A 0–100 score from study quality and agreement
Most supplement evidence is graded C–D. Read it as preliminary signal, not proof.
These are research findings, not promises. A practice does not replace medical treatment.

- Creatine kinaseInflammationproposed
Grounding reduced the loss of CK from injured muscles, indicating reduced muscle damage.
- Hepatic protein catabolismProtein metabolismproposed
Earthing during exercise may inhibit hepatic protein catabolism, leading to lower blood urea levels.
- Immune responseImmune enhancementproposed
Earthing may enhance immune response, possibly by increasing gamma globulin levels.
- InflammationAnti-inflammatoryproposed
Earthing may reduce inflammation by neutralizing free radicals through electron influx.
- Inflammation (CRP)Plantar stimulation and walking exerciseproposed
Barefoot walking stimulates the soles of the feet, improving circulation and reducing inflammation, leading to decreased CRP levels.
- Inflammatory biomarkers, blood viscosity, HRVInflammatory, blood viscosity and heart rate variabilityproposed
Authors cite prior results from this trial indicating improvements in these markers; not measured in the reported outcomes here.
- Neutrophils, eosinophils, plateletsImmune responseproposed
Grounding increased neutrophils, eosinophils, and platelets compared to sham, suggesting modulation of the inflammatory/immune response.
- Orexin neuronsOrexin signaling in the lateral hypothalamusproposed
Reduced orexin expression after earthing mat exposure, potentially reducing arousal and promoting sleep.
- RBC aggregation and blood viscosityRed blood cell surface charge (zeta potential)proposed
Grounding increased RBC zeta potential and reduced RBC clumping, which the authors interpret as reducing blood viscosity.

A general description of the practice, not instruction or medical advice.
Steps
- Find a safe, natural forest trail free of sharp objects or hazardous debris.
- Remove your shoes and socks to allow direct skin contact with the earth.
- Begin with a 5-minute warm-up walk at a leisurely pace to acclimate your feet.
- Walk barefoot for the main session, aiming for a distance of 2.7 to 4.4 km, maintaining a pace that keeps your heart rate at 50-70% of your maximum.
- Focus on the sensations under your feet and your natural surroundings.
- Conclude with a 5-minute cool-down walk at a slower pace, then gently stretch your calves and feet.
Cues
- · Land softly on the midfoot, not the heel.
- · Keep your gaze forward, not down at your feet, to maintain posture.
- · Breathe deeply and rhythmically through your nose.
Common mistakes
- Walking on unsafe terrain with hidden sharp objects.
- Tensing the feet and toes instead of relaxing them.
- Starting with too long a distance before the soles of the feet have adapted.

The mat or patches require direct skin contact and a verified earth connection; an ungrounded outlet provides no earthing benefit. The suggested contact period is typically 2-4 hours while resting, reading, or sleeping.
Equipment: Grounding mat or conductive electrode patches, Connection cord with safety resistor, Wall outlet checker or ground rod
How it's done6 steps · 2 cues · 3 common mistakes
A general description of the practice, not instruction or medical advice.
Steps
- Verify your wall outlet is properly grounded using an outlet checker, or set up a direct ground rod connection.
- Connect the grounding cord to the mat or electrode patches and plug it into the ground port of the outlet.
- Place the grounding mat on your chair, floor, or bed, or apply the electrode patches to clean, dry skin on the target area (e.g., quadriceps, soles of feet).
- Ensure direct skin contact with the conductive surface of the mat or patches.
- Remain in contact with the grounded surface for the desired duration, typically 2-4 hours, while resting, reading, or sleeping.
- Disconnect the cord from the outlet before removing the mat or patches.
Cues
- · Check that the connection cord is not creating a tripping hazard.
- · A slight tingling sensation is normal for some; sharp pain is not and means you should disconnect immediately.
Common mistakes
- Using an ungrounded outlet, which provides no earthing benefit.
- Placing a thick sheet or clothing between the skin and the mat, blocking conductivity.
- Using a damaged or non-safety-rated connection cord.
