Statement on Facemasks:

Dr Margarite Greisz-Brisson MD statement on facemasks:

'The re-inhalation 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 live longer than 3 minutes without oxygen, they cannot survive.  Acute warning symptoms are headaches, drowsiness, dizziness, issues in concentration and reaction of the cognitive system".
