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 facemasks and their effects on our brains:I would like to see that evidence. Carbon dioxide molecules are tiny for a start and would diffuse through the mask. Even before masks you still breath some of what is expelled back in any way from natural breathing. The amount is what makes Co2 a threat. The amount seems so negligible even pulmonary patients can wear them. I can't see how it can shift blood levels of either O2 or Co2 to any worrying level. If you have a study on that please reference it.
“The reinhalation 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 deprivation. 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 reaction time – reactions of the cognitive system.
However, when you have chronic oxygen deprivation, all of those symptoms disappear, because you get used to it. But your efficiency will remain impaired and the under-supply of oxygen in your brain continues to progress.
We know that neurodegenerative diseases take years to decades to develop. If today you forget your phone number, the breakdown in your brain would have already started 20 or 30 years ago.
While you’re thinking that you have gotten used to wearing your mask and rebreathing your own exhaled air, the degenerative processes in your brain are getting amplified as your oxygen deprivation continues.”
