To quote this article https://healthandmoneynews.wordpress.com/2020/10/09/brain-damage-from-masks-cannot-be-reversed/
"Dr. Margarite Griesz-Brisson MD, PhD is a Consultant Neurologist and Neurophysiologist with a PhD in Pharmacology, with special interest in neurotoxicology, environmental medicine, neuroregeneration and neuroplasticity. This is what she has to say about masks and their effects on our brains:
“The rebreathing of our exhaled air will without a doubt create oxygen deficiency and a flooding of carbon dioxide. We know that the human brain is very sensitive to oxygen depravation. There are nerve cells for example in the hippocampus, that can’t be longer than 3 minutes without oxygen – they cannot survive. The acute warning symptoms are headaches, drowsiness, dizziness, issues in concentration, slowing down of the reaction time – reactions of the cognitive system."
This is compounded by forcing your brain to work harder while wearing a mask, such as being masked while taking a cognitive test, slower reaction times lead to a bad cognitive score when then becomes a self fulfilling prophecy.
Other health risks due to wearing of facemasks including the increased risk of bacterial pneumonia due to the masks attracting and holding said bacteria close to the nose and mouth. https://www.globalresearch.ca/medical-doctor-warns-bacterial-pneumonias-rise-mask-wearing/5725848
Evidence also points to toxic air exposure leads to the development of autism. The last think anyone needs is to wear masks that trap toxic air for 8+ hours a day.
On top of which hard evidence about masks causing brain damage is being suppressed by "fact checkers" on social media which have been proven to be more narrative controllers than actual fact checkers. https://thepostmillennial.com/fact-checkers-were-actually-fact-blockers-facebook-fact-check-masks-spread-disinformation
In fact their are AT LEAST 47 studies stating masks are ineffective against COVID and 32 more confirm their negative health effects. https://www.lifesitenews.com/mobile/news/47-studies-confirm-inefectiveness-of-masks-for-covid-and-32-more-confirm-their-negative-health-effects
Dr. Naomi Wolf discussed on Steve Bannon's War Room the dangers of masking children including conative loss. https://rumble.com/vl9f04-theres-going-to-be-chaos-in-the-us.html
The masks themselves have also been proven to be ineffective at preventing the spread of COVID, according to this University of Louisville study. https://escipub.com/Articles/IRJPH/IRJPH-2021-08-1005.pdf
An ethical and careful risk benefit evaluation for the wearing of masks on slowing the spread of SARS-CoV-2 virus has never been made while existing and scientific papers on harmful effects for people and environment have been neglected. https://brownstone.org/articles/why-mask-mandates-should-be-immediately-banned/
Masks have shown to delay speed development in children as well as drop IQ scores dramatically https://www.zerohedge.com/political/speech-therapist-364-surge-baby-and-toddler-referrals-thanks-mask-wearing
