SCIENCE BACKED
Who Is It For
The research
Peer-reviewed studies and reviews exploring how grounding may support sleep, pain, mood, recovery, and circulation.
Sleep & Cortisol
The biologic effects of grounding the human body during sleep as measured during cortisol levels and subjective reporting of sleep, pain, and stress
A pilot study explored grounding during sleep and reported changes in nighttime cortisol rhythm, along with subjective improvements in sleep, pain, and stress.

The Effects of Grounding (Earthing) on Bodyworkers' Pain and Overall Quality of Life: A Randomized Controlled Trial
A randomized controlled trial in bodyworkers reported beneficial effects in areas related to pain, physical function, mood, and quality of life.

The effects of grounding (earthing) on inflammation, the immune response, wound healing, and prevention and treatment of chronic inflammatory and autoimmune diseases
A published review discusses grounding research related to inflammation, immune response, recovery, pain, stress, and sleep.

Frequently Asked Questions
A Grooni Grounding Mat is a conductive bed mat that reconnects your body to the Earth's natural electrical field while you sleep. It works by plugging a grounding cord into the ground port (third prong) of a standard wall outlet, no electricity flows through the mat, only the Earth's free electrons, which transfer to your body through contact and have been shown in peer-reviewed research to reduce inflammation, support deeper sleep, and help restore the body's natural electrical balance. Grooni offers two mat formats built on the same conductive carbon leatherette core:
Carbon Grounding Mat: Micro-perforated carbon leatherette surface, breathable, firm, wipe-clean, and highly durable. Works placed directly on the mattress, under or on top of your sheet. Ideal for those who prioritize durability and low maintenance.
Plush Grounding Mat: Same conductive carbon base with a GOTS-certified organic cotton comfort layer on the sleeping surface, soft, hypoallergenic, and gentle on skin. Ideal for those who prefer the feel of natural fabric and want to sleep directly on the mat.
Both Grooni mat formats aredesigned to work placed under your regular fitted sheet, direct skin contact is not required. The carbon leatherette conducts the Earth's electrons through a thin natural-fiber sheet to your body as you sleep. That said, direct skin contact always produces the fastest and strongest grounding effect, and the Plush Mat's organic cotton surface makes sleeping directly on it just as comfortable as sleeping on a regular sheet. One important rule for both mats:if placing a sheet on top, always use a natural fiber, cotton, linen, or bamboo. Synthetic fabrics like polyester or microfiber act as insulators and will block electron transfer entirely.
Both ground your body using the same Earth connection principle, but they differ in material, maintenance, and use:
Grounding Mat (Carbon Leatherette) Wipe-clean surface, no machine washing needed. More durable, unaffected by body oils, lotions, or detergents. Works under or over a sheet. Preferred for low-maintenance nightly grounding.
Grounding Sheet (Silver-Threaded Fabric) Softer, full-sheet feel. Requires careful machine washing with specific detergents to preserve silver conductivity. Silver threads can degrade over time with improper care. Many users start with a mat for its durability and simplicity, and add a sheet later for full-fabric comfort.
Results vary by person, but peer-reviewed studies show measurable effects, including reduced blood viscosity and cortisol shifts, beginning within a single 30–40 minute grounding session. For sleep quality specifically, most Grooni customers report noticeable improvements within the first 3–7 nights of consistent use. People with chronic inflammation, joint pain, or stress-related sleep issues tend to feel the shift more quickly and more dramatically. If you have excellent baseline health, benefits may be subtler but are still occurring at a cellular level. Grounding is cumulative, the more consistently you use the mat each night, the more pronounced and lasting the results. We recommend committing to at least 30 consecutive nights before evaluating the full effect.
Yes on both counts — and both mat versions qualify.Both the Carbon and Plush Grounding Mats are HSA and FSA eligible, allowing US customers to purchase using pre-tax health savings funds and reduce out-of-pocket cost by 20–35% depending on their tax bracket. This is uncommon in the grounding mat category — most competing brands do not offer confirmed HSA/FSA eligibility
Setup takes under two minutes and requires no tools:
1) Use the included outlet tester to confirm your bedroom outlet is properly grounded, not all three-prong outlets in homes are connected to a ground, particularly in homes built before the 1960s.
2) Place the mat on your mattress, conductive side up (the side with the snap connector).
3) Snap the grounding cord onto the connector at the mat's edge.
4) Plug the single-prong end into the ground port of your verified outlet.
5) Place your sheet over the mat or sleep directly on it. Leave the cord plugged in at all times — simply unsnap it from the mat when cleaning, then reconnect.
