Dr. Russell Blaylock Says That Face Masks Pose Serious Risks To The Healthy

Dr. Russell Blaylock is the author of The Blaylock Wellness Report newsletter. He is a nationally recognized board-certified neurosurgeon, health practitioner, author, and lecturer. For 26 years Dr. Blaylock practiced neurosurgery, and he had nutritional practice. He recently retired from his neurosurgical duties to devote his full attention to nutritional research. Dr. Blaylock has authored four books, Excitotoxins: The Taste That Kills, Health and Nutrition Secrets That Can Save Your Life, Natural Strategies for Cancer Patients, and his most recent work, Cellular and Molecular Biology of Autism Spectrum Disorders.

Masks Are Ineffective

Dr. Blaylock states that “a recent careful examination of the literature, in which 17 of the best studies were analyzed, concluded that, ‘None of the studies established a conclusive relationship between mask/respirator use and protection against influenza infection.’   Keep in mind, no studies have been done to demonstrate that either a cloth mask or the N95 mask has any effect on transmission of the COVID-19 virus. Any recommendations, therefore, have to be based on studies of influenza virus transmission. And, as you have seen, there is no conclusive evidence of their efficiency in controlling flu virus transmission.”

Indeed, on April 1, 2020, the New England Journal of Medicine published an article that concluded that “wearing a mask outside health care facilities offers little, if any, protection from infection.” The article went on to state that “[t]he chance of catching Covid-19 from a passing interaction in a public space is therefore minimal.”  The article was authored by:

[NEJM Editor’s Note: This article was published on April 1, 2020, at NEJM.org. In a letter to the editor on June 3, 2020, the authors of this article state “We strongly support the calls of public health agencies for all people to wear masks when circumstances compel them to be within 6 ft of others for sustained periods.”]

The California Occupational and Health Administration gave official guidance on May 13, 2020, explaining that “[c]loth face covers are not protective equipment and do not protect the person wearing a cloth face cover from COVID-19.”

Denis G. Rancourt, PhD, researched the issue of the effectiveness of wearing a mask and he concluded that masks and respirators do not work in preventing influenza-like illnesses. Dr. Rancourt concluded:

There have been extensive randomized controlled trial (RCT) studies, and meta-analysis reviews of RCT studies, which all show that masks and respirators do not work to prevent respiratory influenza-like illnesses, or respiratory illnesses believed to be transmitted by droplets and aerosol particles.


Furthermore, individuals should know that there is no known benefit arising from wearing a mask in a viral respiratory illness epidemic, and that scientific studies have shown that any benefit must be residually small, compared to other and determinative factors.

CDC: 85% of COVID-19 patients report ‘always’ or ‘often’ wearing a mask

Above is the pertinent Mask Portion of Study Published by the CDC Regarding COVID-19 Contact Exposures

The CDC published a study showing that of the patients who tested positive for COVID-19, 85% (70.6% + 14.4% = 85%) of them either always wore a mask or often wore a mask. Thus, the study indicates that masks are largely ineffective in preventing the contraction of COVID-19. Another interesting outcome of the study is that 88.7% of non-COVID-19 participants either always wore a mask or often wore a mask. They nontheless were sympomatic with flu-like illnesses. There seems to be a high correlation between wearing a mask and becoming ill from disease.

Masks Don’t Work: A Review of Science Relevant to COVID-19 Social Policy

Masks Are Dangerous

Dr. Blaylock further states that “[w]hile most agree that the N95 mask can cause significant hypoxia [reduction in blood oxygenation] and hypercapnia [elevation of CO2 in the blood], another study of surgical masks found significant reductions in blood oxygen as well. In this study, researchers examined the blood oxygen levels in 53 surgeons using an oximeter. They measured blood oxygenation before surgery as well as at the end of surgeries. The researchers found that the mask reduced the blood oxygen levels (pa02) significantly. The longer the duration of wearing the mask, the greater the fall in blood oxygen levels.”

Dr. Blaylock points out that “the importance of these findings is that a drop in oxygen levels (hypoxia) is associated with an impairment in immunity. Studies have shown that hypoxia can inhibit the type of main immune cells used to fight viral infections called the CD4+ T-lymphocyte. This occurs because the hypoxia increases the level of a compound called hypoxia inducible factor-1 (HIF-1), which inhibits T-lymphocytes and stimulates a powerful immune inhibitor cell called the Tregs. This sets the stage for contracting any infection, including COVID-19 and making the consequences of that infection much graver. In essence, your mask may very well put you at an increased risk of infections and if so, having a much worse outcome.”

Dr. Blaylock warns that “there is another danger to wearing these masks on a daily basis, especially if worn for several hours. When a person is infected with a respiratory virus, they will expel some of the virus with each breath. If they are wearing a mask, especially an N95 mask or other tightly fitting mask, they will be constantly rebreathing the viruses, raising the concentration of the virus in the lungs and the nasal passages. We know that people who have the worst reactions to the coronavirus have the highest concentrations of the virus early on. And this leads to the deadly cytokine storm in a selected number. It gets even more frightening. Newer evidence suggests that in some cases the virus can enter the brain. In most instances it enters the brain by way of the olfactory nerves (smell nerves), which connect directly with the area of the brain dealing with recent memory and memory consolidation. By wearing a mask, the exhaled viruses will not be able to escape and will concentrate in the nasal passages, enter the olfactory nerves and travel into the brain.”

Dr. Blaylock concludes that “[o]ne should not attack and insult those who have chosen not to wear a mask, as these studies suggest that is the wise choice to make.”

Wearing a mask will reduce the intake of oxygen and cause carbon dioxide toxicity.

The Daily News reported on May 7, 2020, that two Chinese Schoolboys reportedly died within a week of each other while wearing face masks in gym class. “The students, both 14 years old, were running laps as part of their schools’ required physical examination tests when they both unexpectedly dropped dead.”

One of the teens dropped dead within two to three minutes of beginning his run around a track. The temperature was 20 degrees Celcius (68 degrees Fahrenheit). It was obvious that the two healthy 14 year-olds died from hypercapnia and hypoxia from wearing the masks. But in typical communist fashion, they have not lifted the requirement to wear masks during gym classes. Instead, the deaths have prompted calls to cancel the term’s running exams.

They don’t want you to know how dangerous wearing a mask is for your health. This video demonstrating the dangerous levels of carbon dioxide when wearing a mask was taken down from YouTube within hours of being posted.

Brain Damage From Masks CANNOT BE REVERSED

Doctors Recommend People NOT wear Masks

Based on the latest research studies, the Association Of American Physicians And Surgeons recommends against wearing masks to prevent the spread of COVID-19.

In addition, Dr. Lisa Brosseau ScD, and Dr. Margaret Sietsema, PhD recommend against wearing masks to protect against the spread of COVID-19.

Dr. Brosseau is a national expert on respiratory protection and infectious diseases and professor (retired), University of Illinois at Chicago. Dr. Sietsema is also an expert on respiratory protection and an assistant professor at the University of Illinois at Chicago.

The recommendation of the two doctors is based on a review of available literature and informed by professional expertise and consultation. These two eminent experts concluded: “Our review of relevant studies indicates that cloth masks will be ineffective at preventing SARS-CoV-2 transmission, whether worn as source control or as PPE [Personal Protective Equipment].” The researchers further determined that “[t]here is no evidence that surgical masks worn by healthcare workers are effective at limiting the emission of small particles or in preventing contamination of wounds during surgery.”

That in and of itself is an astounding finding since we are so accustomed to doctors wearing masks during surgery to prevent them from contaminating their patients. The two researchers determined that “[c]linical trials in the surgery theater have found no difference in wound infection rates with and without surgical masks. Despite these findings, it has been difficult for surgeons to give up a long-standing practice.”

Checking the studies themselves bears out their conclusion. One research study conducted by Th. Goran Tunivall, M.D., spanned 115 weeks and involved 3,088 patients. There were 1,537 operations performed with face masks, resulting in 73 (4.7%) wound infections. But among the 1,551 operations performed without face masks, there were only 55 (3.5%) infections. Dr. Tunivall deemed the difference not to be statistically significant and confirmed the data from all other studies that face masks do not decrease post-operative infections. Indeed, Dr. Tunivall stated that “[i]t has never been shown that wearing surgical face masks decreases postoperative wound infections.”

On February 29, 2020, the U.S. Surgeon General Jerome Adams firmly tweeted “Seriously people- STOP BUYING MASKS!” The Surgeon General explained in the tweet that masks “are NOT effective in preventing the general public from catching coronavirus.” (Emphasis in original)

In March 2020 Dr. Anthony Fauci told CBS News chief medical correspondent Dr. Jonathan LaPook that there’s no reason people in the U.S. should wear a mask. Fauci stated that “right now in the United States people should not be walking around with masks … there is no reason to be walking around in a mask.” Indeed, his statement is as true now as when he said it in March 2020.

Dr. Anthony Fauci states that “right now in the United States people should not be walking around with masks … there is no reason to be walking around in a mask.”

Dr. Fauci’s advice has been confirmed as accurate by Dr. Juday Mikovits and Dr. Rahid Buttar.

Both Dr. Fauci and Surgeon General Adams later changed their original no-mask opinions. But their reason for flip-flopping was based on an unproven theory that asymptomatic people can infect other people with coronavirus. President Donald Trump recognized the strange flip-flop of Dr. Fauci and the U.S. Surgeon General about wearing face masks; the president also recognized the danger of wearing face masks. During a July 19, 2020, interview with Fox News’ Chris Wallace, President Trump stated: “Hey, Dr. Fauci said ‘don’t wear a mask.’ Our surgeon general, a terrific guy, said ‘don’t wear a mask.’ Everybody was saying ‘don’t wear a mask.’ All of a sudden everybody’s got to wear a mask. And as you know masks cause problems too.”

The World Health Organization (WHO) has also stated that “[t]he only people who should be wearing masks are healthy people who are taking care of someone who is sick or sick people who are coughing or sneezing when they are in public.”

The advice not to wear a mask is advice that is also confirmed by Drs. Dan Erickson and Atin Massihi.

Dr. Andrew Kaufman notes that not only is it unhealthy to breathe your own exhaled breath but the masks often have toxic materials that are being breathed into the wearers’ lungs. He concludes based upon studies that people who wear cloth masks actually increase their risk of getting sick.

Dr. Kaufman points out that the COVID-19 virus is approximately 100 nanometers (.1 microns) in diameter. According to the FDA, an N95 mask filters out only particles that are larger than .3 microns. All particles smaller than .3 microns will pass through the mask.

Wearing A Mask Can Be Dangerous to Your Health

That means that the smallest hole on an N95 mask is 3 times larger than the COVID-19 virus. It would be like putting up a chain-link fence to keep misquotes out. An N95 mask is completely ineffective to keep put the COVID-19 virus.

Studies Prove Masks are Ineffective and Unsafe

Masks Reduce Oxygen Intake to Dangerously Low Levels

The typical oxygen range at sea level is between 20.8% and 21%. According to the Occupational Safety and Health Administration (OSHA), “[o]xygen deficient atmosphere means an atmosphere with an oxygen content below 19.5%.”

OSHA explains in an official post that “[p]aragraph (d)(2)(iii) of the Respiratory Protection Standard considers any atmosphere with an oxygen level below 19.5 percent to be oxygen-deficient and immediately dangerous to life or health.”

What would cause such an oxygen-deficient condition? According to OSHA, “[o]xygen-deficient atmospheres may be created when oxygen is displaced by inerting gases, such as carbon dioxide.”

That is precisely the condition a person finds himself in when wearing a mask over his mouth and nose. Such a practice lowers the oxygen level below the safe limit of 19.5%, which OSHA has deemed to be “immediately dangerous to life.” That fact seems to be the cause of the deleterious health effects of wearing masks found in the studies cited by Dr. Blaylock.

The typical oxygen level is approximately between 20.8% and 21%. But when a mask is put over the wearer’s mouth and nose, the oxygen level that is being breathed back in by the wearer of a mask drops to a range between 17% and 18%. That reduced level of oxygen, according to OSHA, is “immediately dangerous to life.” And it does not matter whether it is a surgical mask, an N95 mask, or a thin cloth covering. In tests, using all different types of masks, the oxygen level for the wearer dropped to a level below 19.5%, which OSHA has determined is an “oxygen-deficient atmosphere” that is “immediately dangerous to life.” Indeed, one woman who was wearing a mask while driving her car passed out unconscious from oxygen deprivation and crashed into a wooden telephone pole.

The person in the video below used an OSHA approved and calibrated air quality monitor to test the oxygen level beneath his mask he wore on his face. The air quality monitor showed that the oxygen level underneath his surgical mask was 17.4%. Thus, according to OSHA, wearing a surgical mask is “immediately dangerous to life or health” because it lowers the oxygen level to below 19.5%.

Furthermore, according to OSHA, cloth face coverings “[a]re not considered personal protective equipment (PPE). Will not protect the wearer against airborne transmissible infectious agents due to loose fit and lack of seal or inadequate filtration.”

OSHA is also on record as stating that surgical masks “will not protect the wearer against airborne transmissible infectious agents due to their loose fit and lack of seal or inadequate filtration.”

If that is the case why is the Center for Disease Control (CDC) recommending the use of face masks? The theory is that the asymptomatic carriers of COVID-19 could transmit the disease.

Official Reason for Wearing Masks is Unproven by Studies

That new theory is the reason that on April 3, 2020, the U.S. Surgeon General changed course from his February 29, 2020, advice not to wear a mask to state that masks are recommended to prevent the spread of COVID-19. But he explained that the mask is not a protective device. He did not back off on his reason for initially stating that masks are unnecessary and ineffective. He reiterated that a mask does not prevent a person from being infected, the mask only prevents a person who has COVID-19 from spreading it to another person. A mask does not protect a healthy person. The theory is that a mask prevents a person wearing the mask who is a carrier of COVID-19 from spreading the disease to another person.

The recommendation for healthy person to wear a mask is based on the theory that the healthy person could be a carrier of COVID-19 but show no symptoms of the disease; they are called asymptomatic carriers. The problem is that studies have shown that there is no proof that theory of transmission is true. Indeed, the studies have disproved that theory. As reported by CNN, on June 9, 2020, “Maria Van Kerkhove, WHO’s technical lead for coronavirus response and head of its emerging diseases and zoonoses unit, said during a media briefing in Geneva on Monday that ‘it still seems to be rare that an asymptomatic person actually transmits onward to a secondary individual.’”

The next day, Dr. Anthony Fauci came out swinging and stated that Kerkove was wrong. That forced Kerkove to clarify her statement. But she did not retract it. Kerkhove tried to put the toothpaste back in the tube, by explaining (but not retracting) her statement. Kerkhove stated in pertinent part:

“What I was referring to yesterday in the press conference were very few studies — some two or three studies that had been published that actually try to follow asymptomatic cases, so people who are infected, over time, and then look at all of their contacts and see how many additional people were infected. And that’s a very small subset of studies. So I was responding to a question at the press conference. I wasn’t stating a policy of WHO or anything like that. Because this is a major unknown, because there are so many unknowns around this, some modeling groups have tried to estimate what is the proportion of asymptomatic people that may transmit.”

That statement by Kerkove was NOT a retraction of her statement that asymptomatic transmission of COVID-19 is rare. She was simply clarifying that there have been only two to three studies done so far. And, although all those studies show that asymptomatic transfer is rare, those study findings are not the official “policy” of the WHO. In the end, the WHO technical lead for COVID-19 remains on the record stating that it is “rare that an asymptomatic person actually transmits onward to a secondary individual.”

Furthermore, on April 1, 1990, the California Department of Public Health acknowledged in official guidance on face coverings that “[t]here is limited evidence to suggest that use of cloth face coverings by the public during a pandemic could help reduce disease transmission.”

The CDC Recommendation to Wear Masks Is Not Supported by the Studies Cited by the CDC

The facts remain that asymptomatic transfer of COVID-19 is a myth, but that cannot be revealed because if it was generally known then there would be no basis to require healthy people to wear masks and be quarantined. The purported COVID-19 pandemic is an Orwellian scam designed to control the general population.

“And when he thus had spoken, he cried with a loud voice, Lazarus, come forth. And he that was dead came forth, bound hand and foot with graveclothes: and his face was bound about with a napkin. Jesus saith unto them, Loose him, and let him go.” (John 11:43-44)

Expert Testimony: Stephen Petty – On the effectiveness of masks

Why are the governments of the world requiring citizens to wear masks when masks are known to be unsafe and ineffective? It is an integral part of a plan to coerce you into accepting the planned COVID-19 Vaccination. You are being broken down so that you accept the vaccine just to get on with your life.

  1. Great article summarizing that the mask recommendations and binding laws create the opposite effects of what masks are supposed to do. Having seen Dr. Blaylock’s research before, this succinct reference article should be widely shared with all whom have been subjected to inaccurate information that act as if masks have never been studied and researched before now. Thank you for posting this article!

  2. In 1918, during the Spanish Flu, the question of face masks was considered and the consensus opinion of “all leading physicians” was that they do not help and that good health dictates against it. Therefore, they were against universal wearing of face masks. I got the article from the 1918 newspapers (newspaperarchives.com)
