Neurosurgeon: Face Masks Pose Serious Risks To The Healthy

Dr. Russell Blaylock, board-certified neurosurgeon, writes:
As for the scientific support for the use of face mask, 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.”1   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...

Now that we have established that there is no scientific evidence necessitating the wearing of a face mask for prevention, are there dangers to wearing a face mask, especially for long periods? Several studies have indeed found significant problems with wearing such a mask. This can vary from headaches, to increased airway resistance, carbon dioxide accumulation, to hypoxia, all the way to serious life-threatening complications.

There is a difference between the N95 respirator mask and the surgical mask (cloth or paper mask) in terms of side effects. The N95 mask, which filters out 95% of particles with a median diameter >0.3 ┬Ám2 , because it impairs respiratory exchange (breathing) to a greater degree than a soft mask, and is more often associated with headaches. In one such study, researchers surveyed 212 healthcare workers (47 males and 165 females) asking about presence of headaches with N95 mask use, duration of the headaches, type of headaches and if the person had preexisting headaches.2

They found that about a third of the workers developed headaches with use of the mask, most had preexisting headaches that were worsened by the mask wearing, and 60% required pain medications for relief. As to the cause of the headaches, while straps and pressure from the mask could be causative, the bulk of the evidence points toward hypoxia and/or hypercapnia as the cause. That is, a reduction in blood oxygenation (hypoxia) or an elevation in blood C02 (hypercapnia). It is known that the N95 mask, if worn for hours, can reduce blood oxygenation as much as 20%, which can lead to a loss of consciousness, as happened to the hapless fellow driving around alone in his car wearing an N95 mask, causing him to pass out, and to crash his car and sustain injuries. I am sure that we have several cases of elderly individuals or any person with poor lung function passing out, hitting their head. This, of course, can lead to death.

A more recent study involving 159 healthcare workers aged 21 to 35 years of age found that 81% developed headaches from wearing a face mask.3   Some had pre-existing headaches that were precipitated by the masks. All felt like the headaches affected their work performance.

Unfortunately, no one is telling the frail elderly and those with lung diseases, such as COPD, emphysema or pulmonary fibrosis, of these dangers when wearing a facial mask of any kind—which can cause a severe worsening of lung function. This also includes lung cancer patients and people having had lung surgery, especially with partial resection or even the removal of a whole lung.

While most agree that the N95 mask can cause significant hypoxia and hypercapnia, 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.4 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.

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... 
Repeated episodes of hypoxia has been proposed as a significant factor in atherosclerosis and hence increases all cardiovascular (heart attacks) and cerebrovascular (strokes) diseases.10

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.11,12 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.13
Yet, another important witness against the power freaks, Lori Lightfoot, Gretchen Whitmer, Andrew Cuomo, Gavin Newsom, Eric Garcetti, London Breed and Libby Schaaf, when the COVID-19 trials begin.

Hey, hey, ho, ho, power freaks, what lockdown studies did you consider before ordering lockdowns in your regions?

  1. Thanks for this post. Logical discourse is very difficult with advocates of masks. Perhaps this will be more persuasive.

  2. Face mask! No better way to signal virtue.
    Here's a fun exercise: When someone wearing a mask says something to you, say "huh?" , then continuously say you can't understand a thing through that mask. Hey, it's something to do while you're NOT working.

  3. Bob, It would be great if you or Dr. Blaylock could provide links to the referenced studies particularly the flu facemask studies referenced in the beginning of the quote. Cheers

  4. I wear a mask in the grocery store because (1) I've had a few old ladies yell at me, and I don't want them to have heart attacks; (2) It's a small gesture of consideration of other people's wacky anxieties and paranoia; If it puts them at ease, then fine; (3) I let my nose peek out the top, so I can breathe through my nose freely. Most if not all people don't even notice such a breach of "convention."
    I have considered just not wearing one, and when someone calls me out on it, just tell them "haven't you heard the latest?! The lockdown's over! It's all over the news!" By the time the leave the store and get to their car or maybe search the news sites and determine it's not true, I'll be long gone.

  5. I'm not going to forget the lesson I learned in the workforce, where co-workers got flu vaccines and then shed both the virus and the subsequent illness that developed within ten days. Face masks are protective, including to the user, which is not the scientific narrative now. And that's because it isn't science, but indoctrination. I learned well when illness no longer was inevitable because we wore face masks in the workforce, long before coronavirus. If you don't want to wear a face mask, don't wear one. If government measures that may save lives offend you, don't kill yourself because you can't take such pain - disobey! If you attack private business owners who remind you to wear a face mask as posted, pretty soon those private business owners will not even remind you and nobody will question your sovereignty. But please do one more thing - when you get a terroristic jury summons, either flat out refuse to go if for any reason it violates you, or go protest somewhere with a mob. Because the fact is you are owned, and it is demonstrated by the jury duty system.

    1. The jury "duty system," what is that? Many people who get called for jury duty, simply forget about it. In most jurisdictions, you will never hear any more about it. In a few, a judge might call you in, and you can explain that you forgot or that you don't think you ever got the summons. If you get ordered into the jury box, to be asked questions as a prospective juror, there are many ways to get disqualified. Expressing unrelenting bias will almost always work, in a civil or criminal case. Volunteering that you are an anarchist and do not believe in any laws, will also be effective. Answering that you do not trust lawyers or judges is another answer that will usually get you sent home. Just don't insult the judge, that may get you sent to jail.

  6. Very reckless and inaccurate reporting. Healthcare workers with good sense wear N-95. The virus re-entry BS you were pushing has been professionally debunked. I've worn the N-95 pushing a grocery cart around for 2 hours and didn't feel any different and no headache at all. Neither do 10s of 1000s of healthcare workers.
