What masks do and don't do?
excerpts from Studies Involving Mask-Wearing
Study on CDC website which reviewed ten different randomized clinical trials,
world-wide, reviewing highly infectious respiratory virus transmission which
found “no significant reduction” in “transmission with the use of face masks.”

● World Health Organization states there “is no evidence wearing a mask by a
healthy person in a community setting can prevent infection with respiratory
viruses, including COVID-19” and further concludes “universal community
masking” is ineffective at preventing “infection from respiratory viruses,
including COVID-19.” The WHO recommended against wearing medical
masks as they “may create a false sense of security” against COVID-19, while
it further went out of its way to reiterate that there is “no evidence available on
a [mask’s] usefulness to protect non-sick persons.”

● British Medical Journal notes that cloth face masks may INCREASE spread of
virus: “This study is the first RCT of cloth masks, and the results caution
against the use of cloth masks. This is an important finding to inform
occupational health and safety. Moisture retention, reuse of cloth masks and
poor filtration may result in increased risk of infection.”

● Wearing respirators come[s] with a host of physiological and psychological
burdens. These can interfere with task performances and reduce work
efficiency. These burdens can even be severe enough to cause life-
threatening conditions if not ameliorated. Arthur Johnson, Journal of Biological
Engineering (2016).
● When the N95 respirator was tested in use in 2010, the “dead-space oxygen
and carbon dioxide levels did not meet the Occupational Safety and Health
Administration’s ambient workplace standards.”
● In a study conducted by the National Taiwan University Hospital fifteen years
ago, it was found that the use of N-95 masks in healthcare workers caused
them to experience hypoxemia, a low level of oxygen in the blood, and
hypercapnia, an elevation in the blood's carbon dioxide levels. Not only did
the mask create dangerously low levels of oxygen and an equally dangerous
spike in carbon dioxide in the human body, the study found that “medical staff
are at increased risk of getting Severe acute respiratory syndrome; (SARS)
from wearing N95 masks….” Lastly, the study’s authors further found that
“dizziness, headache, and shortness of breath are commonly experienced by
the medical staff wearing N95 masks” and that the “ability to make correct
decisions” was also likely impaired. The Physiological Impact of N95 Masks on
Medical Staff, National Taiwan University Hospital (June 2005).
● Studies show that headaches in medical professionals are commonly found as
a result of mask-wearing, which is a sign of hypoxia: Just under 10% of the
healthcare workers in one study experienced such severe symptoms that they
were forced to take, on average, two full days of sick leave from their
healthcare jobs, while 60% of these healthcare professionals “required use of
abortive analgesics because of headache.” Headaches and the N95 Face-Mask

● 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 – which
is a sign of dangerously low levels of oxygenation – and ALL healthcare
workers felt like the headaches affected their work performance. Ong JJY et al.

● “It is known that the N95 mask, if worn for hours, can reduce blood
oxygenation as much as 20%” which in turn "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.” Are Face Masks Effective Against Covid-19? The Science
Times (May 25, 2020).
● In this study, researchers examined the blood oxygen levels in 53 surgeons.
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 significantly. The longer the duration of wearing the mask, the greater
the fall in blood oxygen levels. Bader A et al. Preliminary report on surgical mask
induced deoxygenation during major surgery. Neurocirugia 2008;19:12-126.
● In a study of dentists and dental assistants who adopted new protocols since
COVID, headaches jumped from 16% pre-COVID to 65%, with half of
respondents (49%) noting it was not hard to breathe “all the time” and 40%
noting it was hard to breathe some of the time. Link to findings
● The immunity of the mask wearer – and his or her subsequent ability to fight
off COVID-19 or any other harmful infection – is actually harmed by wearing a
mask. The drop in oxygen levels (hypoxia) noted in many studies is directly
associated with an impairment in immunity. In terms of the biological effects,
what the studies have shown is that the lowered rate of oxygen (hypoxia) in
turn inhibits the production of the type of primary immune cells that our bodies
use to fight viral infections (known as the CD4+ T-lymphocyte). Functionally
speaking, what happens inside our bodies is that the decrease in oxygen
causes a spike in the level of a compound called hypoxia-inducible-factor-1
(HIF-1). Once that compound spikes, it in turn inhibits the production of T-
lymphocytes we need for our bodies to fight off invaders and infections. Yet
worse, the lack of oxygen stimulates a powerful inhibitor of the immune system
(a cell called the Tregs), which in turn makes one’s body ripe for contracting a
COVID-19 infection and experiencing said illness more severely: “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.” Russell Blaylock, Id. (quoting Shehade H et al. Cutting edge: Hypoxia-Inducible
Factor-1 negatively regulates Th1 function. J Immunol 2015;195:1372-1376. See also:
Westendorf AM et al. Hypoxia enhances immunosuppression by inhibiting CD4+ effector T
cell function and promoting Treg activity. Cell Physiol Biochem 2017;41:1271-84. See further:

Oncoimmunology 2013;2:1 e22355.
● People with cancer may be at a further risk from hypoxia – as cancer cells
grow best in a bodily environment that is low in oxygen. Low oxygen also
promotes systemic inflammation which, in turn, promotes “the growth, invasion
and spread of cancers.” Aggarwal BB. Nucler factor-kappaB: The enemy within. Cancer
Cell 2004;6:203-208, and Blaylock RL. Immunoexcitatory mechanisms in glioma proliferation,
invasion and occasional metastasis. Surg Neurol Inter 2013;4:15.
● Repeated episodes of low oxygen – known as intermittent hypoxia – also
“causes atherosclerosis” and hence increases “all cardiovascular events” such
as heart attacks – as well as adverse cerebral events like stroke. Blaylock,
quoting Savransky V et al. Chronic intermittent hypoxia induces atherosclerosis. Am J Resp
Crit Care Med 2007;175:1290-1297.
● It appears the virus may be able to enter the brain. According to those who
practice neurosurgery, in most instances where the virus enters the brain, it
does so by way of the olfactory nerves (smell nerves) – and accordingly – 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.’’ Blaylock, reviewing Baig AM et al. Evidence of the COVID-19 virus targeting the
CNS: Tissue distribution, host-virus interaction, and proposed neurotropic mechanisms. ACS
