Gary Brecka is a human biologist and performance coach who has become one of the most recognised voices in the biohacking and wellness space. Known for his work with elite athletes and high-performance individuals, Brecka focuses on optimising the body's natural systems — from sleep and recovery to cellular health and energy production.
His approach centres on understanding what the body needs at a biological level and removing the barriers that prevent it from functioning optimally. Grounding is one of the practices he has consistently highlighted as a simple but effective tool for supporting the body's natural recovery processes.
Brecka has spoken about grounding in the context of how modern life has disconnected us from the earth's natural electrical field. For most of human history, people walked barefoot, slept on the ground, and maintained constant contact with the earth. Today, rubber-soled shoes, insulated buildings, and elevated beds mean most people go days, weeks, or even years without direct earth contact.
Grounding — also called earthing — restores this connection. When your body makes contact with the earth's surface (or a conductive grounding product connected to the earth), free electrons flow into your body. Research published in the Journal of Inflammation Research and other peer-reviewed publications suggests this electron transfer may support the body's natural inflammatory response and promote more restful sleep.
Brecka's interest in grounding aligns with his broader philosophy: the simplest interventions are often the most powerful, especially when they work with the body's existing biology rather than against it.
A grounding sheet is a bed sheet woven with conductive material — in Premium Grounding's case, stainless steel fibres — that connects to your home's earth via a grounding cable plugged into the earth port of a standard power outlet.
When you sleep on or near the sheet, your body absorbs free electrons from the earth's electrical field. This happens passively while you sleep, requiring no effort or lifestyle change beyond making your bed.
Most people begin noticing changes within the first few weeks, though the full range of benefits typically becomes apparent after 8 to 10 weeks of consistent use.
Not all grounding sheets are created equal. If you are exploring grounding based on Gary Brecka's recommendations, here are the key factors to consider:
Most grounding sheets on the market use either silver-coated fibres or stainless steel. There are meaningful differences:
Premium Grounding uses 30% stainless steel woven throughout the sheet, ensuring consistent conductivity that does not degrade with regular use and washing.
Look for sheets where the conductive material is woven throughout the fabric, not just coated on the surface. Surface coatings wear off. Woven-in stainless steel maintains its grounding properties for the life of the sheet.
Quality grounding sheets include a built-in resistor in the grounding cable. This is a critical safety feature that limits current flow and ensures the sheet only transfers the earth's natural electrical field — not mains electricity. Premium Grounding includes this in every product.
A good grounding brand will include or offer testing tools so you can verify the connection is working. Premium Grounding offers a socket tester and a multimeter (both available for purchase) for those who want precise readings.
Sleep is the area where most people notice grounding's effects first, and it is central to why Brecka highlights the practice.
A study published in the Journal of Alternative and Complementary Medicine found that participants who slept grounded reported improvements in sleep quality, reduced pain, and lower stress levels. Cortisol measurements showed a normalisation of the cortisol circadian rhythm — the body's natural sleep-wake hormone cycle.
These findings are consistent with the broader biohacking approach that Brecka advocates: support the body's natural systems, and the downstream effects cascade across multiple areas of health.
