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:
"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."
