Earthing: The Most Important Health Discovery Ever?
by: Stephen Sinatra, M.D., F.A.C.C.

Throughout practically all of history, we humans have walked barefoot and slept on the ground, largely oblivious to the fact that the gentle surface energies of the Earth harmonize and stabilize the body’s fundamental biological rhythms and keep inflammation at bay.

In our contemporary Western world, the widespread use of insulative rubber or plastic soled shoes has disconnected us from these nurturing energies and, of course, we no longer sleep on the ground as we did in times past.

New research, which I am proud to be involved in, indicates that this physical disconnect from the Earth creates abnormalities in the physiology and contributes to the chronic inflammation, pain, fatigue, stress, and poor sleep that are so rampant in our modern society.

Along with the research has emerged an amazingly simple remedy for many health problems, including the chronic inflammation regarded as the cause of most common modern diseases, including cardiovascular disease.  The remedy is something right beneath our feet – the Earth itself!

The Greatest Health Discovery in My Career
During my nearly forty years as a practicing cardiologist, I have encountered and used many wonderful natural treatments and seen first-hand astounding lifesaving technological advances. The greatest health discovery of my career, however, is something totally different and more natural than anything I could ever have imagined.

This discovery is called Earthing and it means reconnecting the human body to the Earth’s natural and subtle electric frequencies that few people even know exist. The surface of the planet, science tells us, brims with health-sustaining energy, but until recently the extraordinary benefits that it offers were basically unknown.

Grounding or Earthing and Holistic Health

Thursday, December 9th, 2010

GroundingHow I learned of grounding:

I always had a connection (felt connected) to nature and our planet, once this connection was compromised I experienced dis-ease. I know this from personal experience.

In my quest to reverse my male pattern baldness, improve my vision and heal decaying teeth I researched many diets and theories, trying to figure out what the right thing to eat was, more accurately what my body evolved to eat.

I learned of great concepts such as paleolithic dieting and metabolic typing. Dr. Weston Price, like many others, also figured it was all in the diet, that natives and uncivilized people had great teeth (and hair) due to their diet.

One morning as I continued to research the correct genetic type of foods for me, I had a very simple idea sprout from my mind and catch my attention, “it’s not all in the diet”. While diet is a major factor of the body’s health, I believe looking at diets, supplements and chemicals only for an answer misses 1/2 the reality.

Yes the paleolithic humans ate differently, yes the uncivilized white-teethed tribes ate differently. Some ate raw foods, some ate a vegetarian diet of roots and fruits, some drank raw milk, others ate mostly sea food or meat. Finding commonalities in these diets has been the obsession of many researchers and remains an interest of mine; the same with metabolic typing. One convincing answer that explains why different diets had similar results in natives is that these people ate what was right for their metabolic type.

Keeping that in mind, I sifted through facts and theories on ancient and uncivilized diets, then I noticed something that was even more in common between these ancient people, besides how different their diets were than the typical SAD (Standard American Diet). they all were barefoot (or used thin leather sandals), sat on rocks or the ground, climbed trees, swam, and got a lot of sunshine. These people were more “grounded” than us today. I cannot comment on their spirituality, life habits, culture, mind-set, or rituals but I know they were grounded, got a lot of sun and plenty of functional physical activity.

I theorize that it was not just the diet that made our ancestors healthy, it also must have been their lifestyle: especially grounding activities, functional paleo-type physical activity, and plenty of sunshine. This is not to discount diet, diet is a huge part of health, but not the answer-to-all solution to a holistic whole health.

Early androgenetic alopecia as a marker of insulin resistance.

Matilainen V, Koskela P, Keinänen-Kiukaanniemi S.

Abstract

The previously proven association between androgenetic, alopecia and serious cardiovascular events raises a question of the common pathogenetic mechanism of these disorders. Our practice-based case-control study in men aged 19-50 years showed a strikingly increased risk of hyperinsulinaemia and insulin-resistance-associated disorders such as obesity, hypertension, and dyslipidemia in men with early onset of alopecia (<35), compared with age-matched controls.

This finding supports the hypothesis that early androgenetic alopecia could be a clinical marker of insulin resistance.

Salt, Tea and Blood Pressure in Pastoral Nomads from Phala Tibet

Monday, August 2nd, 2010

These are a few quotes, resources I used in my research relating to the Tibetan Pastoral Nomads and their diet.

Title: Anthropological Fieldwork in Tibet Studying Nomadic Pastoralists on the Changtang
By: Melvyn C. Goldstein and Cynthia M. Beall (Case Western Reserve University)

Quote:

For example, the nomad diet is exclusively animal products and grain, i.e., they consume no vegetables or fruits, yet they show no obvious signs of vitamin or mineral deficiency. And despite the fact that they consume large Quantities of fat and salt from the Tibetan tea (made with butter and salt) they drink throughout the day and from their heavy consumption of meat, cheese and yogurt, they also have low blood pressure–we found no cases of hypertension.

Another quote, this one is from findarticles.com

The high consumption of salt and animal fat does nottranslate into high blood pressure, at least among Tibetan nomads studied last summer by anthropologist Cynthia M. Beall of Case Western Reserve University. Beall, who is working with Goldstein in Tibet, found no cases of hypertension among more than 120 Phala nomads. The average blood pressure of those measured so far is below reported averages for men and women in the United States. The nomads’ diet consists of meat, dairy products, barley flour and tea flavored with salt and butter; fresh fruits and vegetables are scarce at the 3-mile-high elevation. Beall now plans to measure the amount of salt consumed by nomads. Several factors, including extreme altitude, may help to depress blood pressure, she suggests.

Beall uncovered another surprising finding after takingblood samples from 110 Phala men and women and calculating their hemoglobin concentration–a measure that usually increases at high altitudes. Hemoglobin concentration was greater for Phala nomads than for sea-level populations or for Tibetans living at 12,000 feet above sea level, but residents of Chile’s Andes Mountains have the highest known hemoglobin rates at elevations several thousand feet lower than the Tibetan plateau. A larger sample of Phala nomads will be studied for hemoglobin concentration as well as for other measures of oxygen delivery in the body, says Beall.

The (political) science of salt
Gary Taubes. Science. Washington: Aug 14, 1998. Vol. 281, Iss. 5379; pg. 898, 9 pgs

Abstract (Summary)

Taubes discusses the debate over the benefits of salt reduction, which shows how the demands of good science clash with the pressures of public health policy.

Quotes from the full article:

The last 5 years have also seen two studies published-the latest this past March in The Lancet-suggesting that low-salt diets can increase mortality. Both studies were done by Michael Alderman, a hypertension specialist at New York City’s Albert Einstein College of Medicine and president of the American Society of Hypertension. Epidemiologists-and Alderman himself-caution against putting too much stock in the studies. “They are yet more association studies,” says Swales. “Any insult you make of Intersalt you can make of those as well.” But Alderman also notes that only a handful of such studies comparing salt intake to mortality have ever been done, and none have come out definitively negative. “People just rely upon statements that [salt reduction] can’t really do any harm,” says Swales. “It may or may not be true. Individual harmful effects can be as small as beneficial effects, and you can’t detect those in clinical trials either.”

After publication of his second study, Alderman recruited past and present presidents of hypertension societies and the American Heart Association and wrote to Lenfant at the NHLBI “urging prompt appointment of an independent panel of qualified medical and public health scientists to review existing recommendations [on salt consumption] in light of all available data.” In April Lenfant told Science that he had agreed to proceed with the review. If such a panel should convene, Hennekens has one observation worth keeping in mind: “The problem with this field is that people have chosen sides,” he says. “What we ought to do is let the science drive the system rather than the opinions.”

Dietary sodium and blood pressure: interactions with other nutrients.

Kotchen TA, Kotchen JM.

Department of Medicine, Medical College of Wisconsin, Milwaukee 53226, USA.

Abstract

This paper reviews the evidence that salt sensitivity of blood pressure is related both to the anion ingested with sodium as well as to other components of the diet.

In several experimental models of salt-sensitive hypertension and in humans, blood pressure is not increased by a high sodium intake provided with anions other than chloride. Salt-induced increase of blood pressure depends on the concomitant ingestion of both sodium and chloride.

Both epidemiologic and clinical evidence suggest that sodium chloride-induced increases of blood pressure are augmented by diets deficient in potassium or calcium. In experimental animals, a high intake of simple carbohydrates also augments sodium chloride sensitivity of blood pressure.

These observations indicate that the effect of dietary sodium on blood pressure is modulated by other components of the diet.

Does sodium play an adverse role in hypertension?

Singh RB, Singh NK, Mody R, Cameron EA.

Medical Hospital and Research Centre, Moradabad.

Abstract

It is clear that salt is known to be a health hazard from the ancient times. Sodium intake, which was minimal during evolution, increased significantly with the civilization. The rise in prevalence of hypertension in populations with increased consumption of salt suggested a casual relationship. However, several of these studies showed conflicting results.

Many investigators agree that salt-sensitive persons often have a family history of hypertension. Such individuals possess a sodium transport inhibitor in the arterial smooth muscle cells, which affects their sodium handling (as compared to other persons).

However, many of the putative defects related to sodium can be dissociated from blood pressure and sodium consumption status. It is possible that calcium defects of deficiency of potassium and magnesium follow hypertension and sodium status. For example, the pressure response to sodium chloride may be dissociated from sodium, which may be secondary to adverse effects of chloride on calcium homeostasis. Clinical studies also indicate that the role of sodium is controversial in hypertension.

Sodium restriction can benefit salt-sensitive persons and might not otherwise. However, most authorities believe that moderation of salt intake to a relevant extent is justifiable.

Calcium, Magnesium, Potassium, Phosphate, Vitamin D and Hypertention in Dahl Rats – Sources

Hypertension development in Dahl S and R rats on high salt-low potassium diet: calcium, magnesium and sympathetic nervous system.

Wu X, Ackermann U, Sonnenberg H.

Department of Physiology, University of Toronto, Ontario, Canada.

Abstract

Dietary combination of high salt with low potassium (HSLK) exacerbates hypertension development in Dahl salt-sensitive (S) rats, and produces a mild degree of hypertension in otherwise salt-resistant (R) rats. Increased blood pressure in both strains is associated with increased urinary excretion of calcium and magnesium. The objective of this study was to determine the effect of blood pressure on body balance of these ions in Dahl rats on HSLK diet. Two groups of S and two groups of R weanlings were all placed on HSLK diet (NaCl=8%, K=0.2%) for eight weeks. One group of each strain was subjected to chemical sympathectomy with 6-hydroxydopamine (6-OHDA) to counteract hypertension development. Urinary norepinephrine was used to determine efficacy of 6-OHDA treatment. Systolic blood pressures of conscious animals were measured daily throughout the study. The last three days on the diet were used to determine total dietary intake and urinary as well as fecal excretion of sodium, calcium and magnesium. At the end of the study, extracellular fluid volume, serum aldosterone and parathyroid hormone were analyzed. Final systolic blood pressures in the 4 groups were as follows: S=235+/-9 mmHg (n=9); R=155+/-3 mmHg (n=8); 6-OHDA S=151+/-6 mm Hg (n=8); 6-OHDA R=117+/-6 mm Hg. Chemical sympathectomy decreased blood pressure in both S and R rats. There was no indication of sodium accumulation in S rats. Associated with reduced parathyroid hormone levels the S strain had significantly less positive balance for calcium than the R strain, primarily due to increased urinary excretion. A less positive balance for magnesium was also observed, due mainly to relatively reduced intestinal absorption of the ion. We conclude that the HSLK diet is associated with inappropriate activation of the sympathetic nervous system and increased arterial pressure in both strains. In addition, since divalent cations may influence blood pressure, we suggest that the observed abnormalities in calcium and magnesium metabolism might independently promote hypertension development in the S strain.
