When you first put your mask on, does it smell bad? (You get used to it after a while.)
The human body is a chemical factory and must constantly remove toxic products—some from food or the environment, some from your own metabolism. As we learned from the space program, you make a huge number of volatile organic compounds (VOCs), such as formaldehyde and trichloroethylene (TCE). These poisons are eliminated by your liver, kidneys, GI tract, sweat glands—and your lungs.
Your breath contains thousands of chemicals.
We are hyper concerned about outdoor air pollution, such as minuscule concentrations of PM2.5s (tiny particulates) from diesel exhaust or coal-fired generating stations. But what is concentrated inside your mask?
One thing I can measure is carbon dioxide. Outside air contains about 400 ppm (parts per million) CO2. Inside most masks, my CO2 monitor goes off scale at > 10,000 ppm, twice what OSHA considers acceptable for an 8-hour exposure in a workplace. Oxygen inside the mask may also be lower than acceptable in a workplace. If you have a pulse oximeter, you can measure your blood oxygen saturation without and with the mask. Some people (not all) see a decrease.
In addition to CO2 and VOCs, other things that may be concentrated inside the mask include fibers from the mask itself, bacteria, and fungi. Skin infections and increased tooth decay and periodontal disease are reported.
And viruses are also trapped there. Dr. Peter McCullough warns against self re-inoculation of the viruses you are trying to flush out of your nose.
German neurologist Margarite Griez-Brisson warns about long-term consequences of oxygen deprivation. Are we starving the developing brains of children and adolescents, who will as a result never reach their full potential? Are we causing irreversible damage that will show up in increased rates of dementia? Among other adverse effects, American neurosurgeon Russell Blaylock warns that chronic hypoxia impairs immunity.
How many cases of respiratory illness are we preventing? A CDC study showed that of patients presenting to a clinic with a respiratory illness, 71 percent of the PCR-positive and 74 percent of the PCR-negative patients said they “always” wore a mask, and only 8 percent of each group said they rarely or never wore a mask.
Mask mandates force the population into a giant non-consented experiment of breathing polluted air in the hope that it might reduce the risk of transmission of COVID-19 by an unknowingly infected person. Neither risks nor benefits are being measured.
