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 re-breathing of our exhaled air will without a doubt create oxygen deficiency and a flooding of carbon dioxide. We know 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 the 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 neuro-degenerative 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 you've gotten used to wearing your mask and re-breathing your own exhaled air, the degenerative processes in your brain are getting amplified as your oxygen deprivation continues.
The second problem is that nerve cells in your brain are unable to divide themselves normally. So in case our govern...[ Click here for full document ]
