The lethal link between masks, hypoxia, and blood clots

An abnormally low level of oxygen in the blood negatively impacts the body in the form of hypoxia, a potentially deadly condition.

Just a 5% drop in blood oxygenation is considered “abnormal” but a 15% reduction will cause noticeable symptoms. These include headaches, dizziness, nausea, and cognitive impairment. Even surgeons can suffer low O2 and associated symptoms merely from wearing a surgical mask. But can hypoxia have more serious side effects?

Air travelers, mountaineers, and climbers are known to suffer an increase in blood clotting issues, namely venous thromboembolisms (VTE) like pulmonary embolism or deep-vein thrombosis. The cause of VTE at altitude is usually inadequate oxygen. High-altitude travel advisories for mile-high cities abound. And blood clots are not a minor affliction; VTE kills 300,000 people a year.

At sea level the air we breathe is 21% oxygen. High altitude where pilots can suffer ill effects begins at even 5,000 feet. The N95 mask commonly worn eclipses that elevation; it’s well known to cause a 20% reduction in O2, which simulates the 16% O2 of 6,000 feet. But is that dangerous? Could this increase the risk of potentially lethal blood clots?

Two years ago a causation was found– the biological link between hypoxia and blood clotting. The study discovered that hypoxia downregulates expression of the important natural anticoagulant protein S. The level of protein S was found to drop by 50% when O2 levels were at 15%.

As the N95 simulates a similarly low oxygen saturation, this indicates wearing a mask may decrease your natural ability to prevent blood clots by 50%.

This has potentially serious implications. A web search for “blood clot covid” returns many stories about the virus-induced blood clotting and its lethality for those patients. In late June researchers in Utah discovered that platelet hyperreactivity is the cause of COVID-19 clotting.

It’s a simple bit of math: if you’re masked and hypoxic with increased blood clotting, and then you get a virus which causes more blood clots, isn’t that a perfect recipe to die fast?

And this is the thought that has been keeping me up at night: I picture people who’d otherwise survive their COVID-19 case strapping on a mask to “protect others” and essentially killing themselves.

Also worrying me is the common expectation that to not infect others, those with the virus even recovering at home should mask up as often as possible. I strongly suspect that staying masked and hypoxic with increased blood clotting is not conducive to a speedy recovery from COVID-19 clotting issues.

I’m sure you can identify the many problems with intentionally increasing the blood clot risk for the general population through mass compulsory masking. Already millions of people take blood thinners just to stay alive. How could it possibly be a good idea to hinder their already diminished natural clotting ability?

And what about people who are unaware they have an existing clotting disorder and then wear a mask at work for hours? Especially those most at risk of VTE, who are also the most at-risk for COVID-19?

This information brings up hard questions that demand answers.

Why has this extremely serious and potentially fatal side effect from wearing a mask, especially N95, not been the subject of widespread health alerts?

How could any qualified health official not already know about the well established blood clot dangers of mandatory hypoxia for the masses, especially COVID-19 patients? If they did know, would they do anything?

And, what if they already know?


On July 6, a message was sent to Oregon Health Authority with a summary of this information, but unfortunately only received an auto-reply, stating “because of the large volume of questions, we cannot directly reply to every email.” A direct reply has not yet been received.

  2. I’m impressed, I must say. Seldom do I come across a blog that’s both equally educative and amusing, and let me tell you, you have hit the nail on the head. The problem is something which too few men and women are speaking intelligently about. Now i’m very happy I came across this in my hunt for something regarding this.


  3. Superb website you have here but I was curious about if
    you knew of any message boards that cover the same topics talked about
    in this article? I’d really like to be a part of group where I

  9. I couldn’t refrain from commenting. Exceptionally well written! I have been surfing online more than 3 hours these days, but I by
    no means found any attention-grabbing article like yours.

    It is beautiful price sufficient for me. In my opinion, if all site
    owners and bloggers made good content as you did, the net will probably be a lot
    more helpful than ever before. Amazing! This
    blog looks exactly like my old one! It’s on a entirely different topic but it has
    pretty much the same page layout and design. Great choice of colors!


  10. Holy crap, bro!

    This is one of the best articles I’ve seen on this area of discussion. Be mindful, the VTE problem is most likely going to be more a problem for those who are already at risk of strokes and other forms of blood clots.

    The Oxygen-deprivation problem is well-documented and very well-known in many scientific circles (except the bureaucratic ones, of course) in direct relation to extended use of prosthetic face masks, and similar. I am aware that there are nearly a dozen such Randomly-Control Tests/Experiments (RCT’s) that have produced some very convincing hard data to confirm this. Many of these tests were done even as far back as the eighties and nineties, because it was apparently becoming commonplace that many healthcare workers, EMT’s, and other health-professionals were showing high percentages of health problems related to Oxygen deprivation – all in direct relation to the wearing of “protective face masks” for many hours, daily.

    I am in the process of informing as many of my local and state officials by email, of this obnoxious fraud and “bad science” behind the various “mask mandates”. In my home town, many of our charitable church meals (for the poor and needy) are being shuttered under the excuse of this “COVID-19”! – I am ONE of those who depends on them. If THIS is going to result in many of us poor going hungry, all out of politics-masquerading-as-science, then this the words of truth and true science need to be spread far and wide!

    1. Yes, I was wondering that myself about who may be at risk for VTE, which is why near the end I did try to get that in there. Those said to be at risk are the same “vulnerable” populations to covid. I just want people to stop and think about the many many ways masks can cause harm to many people, and help it hit home in a real way.
      Food insecurity is affecting a lot more of us than the MSM is letting on, and I too am beginning to have issues keeping a full pantry.
      Best of luck in your fight, thank you for commenting, and be well!
      Thanks again for commenting!
