Masks and Covid-19. Let’s start from oxygen!
Oxygen is the element that makes us live. A slight reduction in the supply of oxygen to the brain is enough to compromise alertness and behavioral response.
In this regard, I want to talk about a study conducted by the Institute of Molecular Bioimaging and Physiology of the National Research Council (IBFM-CNR) in collaboration with the University of Milan Bicocca. The research was presented at the World Congress of Neurosciences organized in Washington (USA) by the Society for Neuroscience (SfN).
“hypoxia or the lack of oxygen – explains Alberto Zani of the IBFM-CNR of Segrate – characterizes various clinical disorders, such as asthma or brain injuries, but it can also concern healthy individuals who stay at high altitudes: while we know that hypoxia, especially if serious, it may have effects on memory or calculation capacity, the study on supervisory systems was previously unpublished. “
“The differences detected experimentally – adds Alice Mado Proverbio della Bicocca – indicate how even a slight hypoxia acts on the cerebral system of regulation of the alert state, compromising the speed of response to stimuli: thanks to a particular magnetic resonance technique it was also possible highlight the activation of the medial anterior cingulate cortex and of the para-hippocampal gyrus of the left hemisphere, which suggest a state of exertion or suffering induced by hypoxia. “
“What about data?? The data that emerged – Zani concludes – have important implications for people who work in extreme environments, for the study of the nervous processes involved in states of consciousness and in patients with brain suffering: the effects of stress from prolonged exposure are also relevant to a pressurized environment, such as that of airplanes, or to air conditioning at sea level, where there is no exchange of natural air “.

Masks and Covid-19
Today we find ourselves breathing through sanitary tools: the masks!
We know that we can have various types of masks. There are the surgical ones, the ffp1, the ffp2, the ffp3, increasingly strong and impenetrable barriers from the coronavirus. Already! Thank god!! They save our lives!! But…. there is always a “but”!
There is always an opposite effect but with the same force of action: hypoxia. Clearly mild, but such as to cause all the symptoms that our patients are accusing in these two months: a great tiredness, exhaustion not adequate for the physical activity that is being practiced.
Confusion: patients tell me they are “like in a big bubble”, dulling. Memory labile. We make unusual gestures such as putting a lasagna to cook in the fridge and not in the oven. Many dizziness, palpitations, a feeling of heart in the throat. Certainly, there is hypoxia and also, an activation of various inflammation mechanisms.
To all my patients I suggest a correct diet and above all to stay as much as possible on the balcony and to take at least two walks a day without a mask!!! When out in the open air, walk without a mask! In closed environments such as lifts, shops or medical offices, is it necessary to bring the mask, but in the open air? Follow the video below.
I will explain what is going on … what this mild hypoxia can do to us.
