Absolutely not true that mask wearing causing atrial fibrillation or hypoxia.. It is also BS that most people with asthma can't wear masks. For the love of heaven, allergists often RECOMMEND MASKS be work by asthmatics during times of pollen, pollution, flu season etc. People who have so much anxiety and/or are prone to hysteria or panic attacks that they claim to be dizzy or sick when wearing a mask need mental health treatment. Do you think doctors and nurses - and I assure you, some of them even have asthma and heart conditions themselves - work for hours in surgery wearing masks and don't become ill? I realize the propaganda is rife. I also realize that the lack of leadership in this country - where public health decisions are made by politicians with their own agendas and not PROVEN HEALTH PROTOCOLS that have virtually halted COVID-19 in other localities -- is rife. It is selfish and irresponsible in a time of pandemic to not wear a mask. Unfortunately, the absolutely false, bogus and despicable "Plandemic" - featuring a researcher I remember from my own work was thoroughly discredited and her "study" absolutely shown to be the result of contamination, not a virus "discovery" in 2009 - fed the dangerous-to-health lies about mask wearing. Here is information about the silly untrue but oft repeated "information" about masks "dangers" from a REAL and highly trained physician,Jennifer Kasten, MD, (pathologist with degrees in medicine from the Columbia University College of Physicians and Surgeons, infectious disease epidemiology (CID) from the London School of Hygiene and Tropical Medicine, postgraduate work in the mathematical modeling of infectious disease at Oxford University and MORE) :
Mikovits states that a mask causes the wearer to re-inhale their own carbon dioxide -- "a toxic gas!" Fortunately, it's not a steel-lined trap. Just as you can suck air in through a mask rather easily, so can you exhale air out through it. If you'd like to feel the difference, clamp your hand over your mouth and nose and take a stroll. Also, exhaled air is about 16% oxygen, versus atmospheric air which sits at 21%. It's not pure carbon dioxide, like the clouds on Venus.
You also cannot infect yourself with your own virus. If it comes out of you (i.e., virus droplets in exhaled breath) putting it back in you won't make you any sicker. Being exposed to the atmosphere -- in fact, leaving its host cell at all -- is a very precarious thing for a virus. It risks drying out its protective moisture coat and falling apart. Taking a brief, exciting tour out your nose, into your mask, and back inside does not energize it, but instead risks inactivating it entirely." https://www.medpagetoday.com/infectiousdisease/generalinfectiousdisease/86461
