Grounding: A Simple, Pleasurable Way to Reduce Inflammation and Chronic Disease — With Dr. Joe Mercola
Did you know the energy from the Earth can help you live a healthier life? The concept is known as earthing or grounding, and it is no more complicated than walking barefoot. In fact, using grounding sheets or spending time barefoot outdoors may be one of the most overlooked strategies for improving human health.
In "Down to Earth" — which received the IndieFEST Award of Excellence for a documentary short in January 2017 — Dr. Joe Mercola speaks alongside other experts to shed light on this simple yet commonly overlooked practice. As cardiologist Dr. Stephen Sinatra, author of Earthing: The Most Important Health Discovery Ever?, explains in the film:
"[G]rounding is literally putting your bare feet on the ground. When you do that, you're in contact with the Earth, and mother Earth is endowed with electrons, and these electrons are literally absorbed through your feet. It's like taking handfuls of antioxidants, but you're getting it through your feet."
Why Your Body Needs Grounding
Research suggests a general lack of grounding — also referred to as "electron deficiency syndrome" — has a lot to do with the rise of modern diseases. It is not unusual for Americans to spend entire days without being grounded. Though it has become the norm, it is completely unnatural, and did not become widespread until the advent of shoes with artificial soles that prevent grounding.
When you are grounded, free electrons from the Earth are transferred into your body. These free electrons are among the most potent antioxidants known to man. Because electrons are negatively charged and free radicals are positively charged, any free radicals encountered in your tissues are electrically neutralized or cancelled out by these free electrons. This is why grounding is so effective against chronic inflammation.
Dr. Laura Koniver, who discovered grounding quite by accident after it seemed to soothe her crying infant, says in the film, "Grounding … supports the body as a whole but it specifically supports organ systems down to the tissues and the cellular function of the entire body."
Additionally, while you may not think of your body as a generator of electricity, you are very much an electrical being. This is in large part why it is so important to use grounding to harness the electrical charge of the Earth. In the film, Gaetan Chevalier, Ph.D., an engineer and physicist who has studied grounding, explains:
"Unbeknownst to us, we live inside a battery. The surface of the Earth is charged negatively and the ionosphere, a layer of the atmosphere about 60 miles up, is ionized by the sun. The rays of the sun are so strong that they split the molecules in two — a positive charge and a negative charge. The negative charges are transferred to the surface of the Earth, through lightning mainly, and the positive charges stay 60 miles up. The problem arises when we don't have a negative charge. We need grounding just as we need air and we need sunshine."
Grounding Reduces Electric Field Induction
Furthermore, there is strong evidence that grounding reduces the voltage induced on your body from electricity in your environment — a factor that has become increasingly important in the modern world. As noted in the 2012 review, Applewhite, an electrical engineer and expert in electrostatic discharge systems, was both subject and author of a key study.
Measurements were taken while ungrounded and then grounded using a conductive patch and conductive bed pad. Each method immediately reduced the common alternating current (AC) 60 Hz ambient voltage induced on the body by a highly significant factor of about 70 on average. The study showed that when the body is grounded, its electrical potential becomes equalized with the Earth's electrical potential.
This, in turn, prevents the 60 Hz mode from producing an AC electric potential at the surface of the body and from producing perturbations of the electric charges of the molecules inside the body. The study confirms the "umbrella" effect of earthing the body explained by Nobel Prize winner Richard Feynman in his lectures on electromagnetism. Feynman said that when the body potential is the same as the Earth's electric potential, it becomes an extension of the Earth's gigantic electric system — and the Earth's potential becomes the "working agent that cancels, reduces, or pushes away electric fields from the body."
Proven Health Benefits of Grounding and Earthing Sheets
While it may sound too easy, the simple pleasure of walking barefoot — or sleeping on grounding sheets — can be a powerful health-promoting activity. A scientific review published in the Journal of Environmental and Public Health in 2012 found that grounding can help with the following:
- Improve quality of sleep and feelings of restfulness upon waking.
- Reduce muscle stiffness and soreness.
- Reduce chronic pain.
- Normalize secretion of the stress hormone cortisol, so that it adheres to a typical cycle of peaking in the morning and dipping lowest at midnight. This in turn helps promote more restful sleep and improve blood sugar regulation and weight control.
- Reduce stress and balance your autonomic nervous system by stimulating the parasympathetic nervous system (which rules the "rest and digest" functions) and quieting the sympathetic nervous system (which cues the "fight or flight" response).
- Reduce the severity of the inflammatory response after intense workouts.
- Raise your heart rate variability — your heart's ability to respond to stimuli.
- Speed up wound healing.
- Improve mood. In one study, grounding for one hour significantly improved mood among adults.
How Grounding Reduces Inflammation and Supports Cardiovascular Health
Grounding has also been shown to reduce inflammation. In the film, grounding pioneer Clint Ober explains how grounding quenches inflammation: "Inflammation is produced by neutrophils, which are white blood cells. [When] you have an injury … a damaged cell … these white blood cells come over and encapsulate the damaged cell and … release reactive oxygen species, which rip electrons from the damaged cell and that destroys the damaged cell.
If there's not enough free electrons there to reduce the remaining radicals, they're going to steal an electron from a healthy cell and in the process damage it. Then the message goes out to the immune system and another neutrophil does the same thing and eliminates that cell, and then you have a chain reaction."
In addition, grounding can thin your blood, making it less viscous, by strengthening the negative electrical surface charge on your red blood cells. This improves their ability to repel each other and allows them to flow more easily through tiny capillaries — incredibly valuable since cardiovascular disease is correlated with thicker, slow-moving blood. It can also help protect against blood clots.
This blood-thinning effect is so profound that if you are taking a blood thinner such as Coumadin, you should consult your doctor before grounding regularly. You may need to lower your dosage to avoid overdosing on your medication.
Research published in the Journal of Alternative and Complementary Medicine revealed that two hours of grounding increased the surface charge of red blood cells, thereby reducing blood viscosity and clumping. According to the authors, "Grounding appears to be one of the simplest and yet most profound interventions for helping reduce cardiovascular risk and cardiovascular events."
Grounding and the Role of Structured Water in Your Cells
Grounding also works to increase the structure of the water in your cells. Water is present in every cell in your body, and this water is highly ordered (structured) and charged. If you don't have properly structured water in your cells, it can impact the functioning of the much larger protein molecules that interface with the cell.
The water inside the cell also interfaces with water outside the cell, which has the opposite charge, creating a battery effect. Your body's ability to generate electricity is a key part of achieving and maintaining health. Electrical charges delivered from cell to cell allow for nearly instantaneous communication within your body, controlling the rhythm of your heartbeat, the movement of blood, and much more.
In fact, most of your biological processes are electrical. The water in your cells achieves its ordered structure from energy obtained from the environment, typically in the form of electromagnetic radiation, including sunlight and infrared heat. However, grounding may also play an important role.
Just as water increases in structure when a negative charge is introduced by an electrode, the negatively charged electrons you receive when grounded help increase the structure of the water in your cells. By restructuring this water, you promote more efficient tissue healing. So, when you ground — whether outdoors or through earthing sheets — you are charging every single cell in your body with energy your body can use for self-healing.
How and Where to Ground Outdoors
While connecting just about any part of your skin to the Earth is beneficial, one particularly potent area is the center of the ball of your foot — a point known to acupuncturists as Kidney 1 (K1). It is a well-known acupuncture point that conductively connects to all of the acupuncture meridians in your body. Exercising barefoot outdoors is a great way to incorporate earthing into your daily life and will also help speed up tissue repair and ease muscle pain associated with strenuous exercise.
The ideal location for walking barefoot is the beach, close to or in the water, as saltwater is a great conductor. Your body is also somewhat conductive because it contains a large number of charged ions, called electrolytes, dissolved in water, making your blood and other body fluids good conductors.
A close second would be a grassy area, especially if it is covered with dew, and/or bare soil. Ceramic tiles and concrete are good conductors as long as they have not been sealed — painted concrete does not allow electrons to pass through very well. Materials like asphalt, wood, rubber, or plastic will not allow electrons to pass through and are not suitable for barefoot grounding.
While any amount of grounding is better than none, research has demonstrated it takes about 80 minutes for free electrons from the Earth to reach your bloodstream and transform your blood. That is when you reap the greatest benefits. As a result, ideally aim for 80 to 120 minutes of grounding each day.
How to Ground Indoors Using Grounding Sheets and Earthing Mats
Just as walking barefoot was once widespread, so too was sleeping on the ground. In the modern world, sleeping indoors serves to further insulate you from the Earth. There is also the issue of elevation. When you are grounded, your body cannot carry a charge — which is good. The greater the distance between your body and the Earth, the greater the charge your body carries.
In fact, this has been precisely calculated: for every meter (3.28 feet) you are above the ground, 300 volts of charge will build up in your body. So, if you are in a second-story bedroom, your charge would be approximately 1,000 volts on average, and this increased charge may raise your risk of health problems. For example, one 2009 study found a 40 percent increase in stroke risk among people living in multistory homes.
Flying can also make you severely ungrounded. Fortunately, when indoors and/or at elevation, you can ground yourself using several practical methods:
- Using grounding sheets to ground your mattress while sleeping. Most modern homes built after 1970 have a grounded electrical system, making this approach straightforward and effective.
- Using an earthing mat or grounding mat for sleep and rest, making sure your bare skin is in direct contact with it. There should not be a layer of clothing between you and the mat.
- Using a grounded yoga mat when exercising indoors. Research has shown doing yoga indoors on a grounded yoga mat helps reduce blood viscosity and exercise-induced inflammation — the same effects you would expect from walking barefoot outdoors.
- Touching the faucet with one hand while shaving or brushing your teeth with the other.
- When flying, taking off your shoes and placing your feet (bare or with socks) on the steel struts of the chair in front of you.
Grounding May Be Essential for Life and Long-Term Health
It is important to understand that grounding is not a "treatment" or "cure" for any disease or disorder. Rather, it is one of the key mechanisms by which your body maintains equilibrium and health. The human body evolved in constant contact with the Earth, and your body needs this continuous interchange of energy to function properly.
Free radical stress from exposure to pollution, cigarettes, pesticides, processed foods, and electromagnetic radiation continually depletes your body of electrons. The Earth, however, is always electron-rich and can serve as a powerful and abundant supply of antioxidant, free radical-busting electrons — provided you make an effort to stay grounded.
Without a proper supply of antioxidants, free radicals can overwhelm your system, leading to oxidative stress, inflammation, and accelerated aging. "We now know that oxidative stress causes disease. It causes inflammation," Dr. Sinatra says. "[But] we have this Earth — Mother Earth — that's going to give us all these free electrons."
In conclusion, exercising barefoot outdoors is a wonderful way to incorporate grounding into your daily routine. Alternatively, using grounding sheets or an earthing mat while you sleep ensures you benefit from the Earth's natural healing potential every single night — even when you cannot get outside.
