physiological, psychological and health effects are established. Is has been hypothesized that facemasks have compromised safety and efficacy profile and should be avoided from use. The current article comprehensively summarizes scientific evidences with respect to wearing facemasks in the COVID-19 era, providing prosper information for public health and decisions making.”

The authors found that:
“Exercising with facemasks may reduce available Oxygen and increase air trapping preventing substantial carbon dioxide exchange. The hypercapnic hypoxia may potentially increase acidic environment, cardiac overload, anaerobic metabolism and renal overload, which may substantially aggravate the underlying pathology of established chronic diseases. Further contrary to the earlier thought, no evidence exists to claim the facemasks during exercise offer additional protection from the droplet transfer of the [COVID] virus.”
We then examined a recent PubMed study on the impacts of walking while wearing masks Jul-Aug 2021;34(4):798-801. doi: 10.3122/jabfm.2021.04.200559.
Effects of Wearing Facemasks During Brisk Walks: A COVID-19 Dilemma
The objective of this study was to evaluate the effects of facemasks on inhaled oxygen and exhaled carbon dioxide.
Healthy adults were assessed at rest and during slow and brisk 5-minute walks, with and without masks. What the results showed was that:
“EtCO2 increased; the rise was significantly higher while wearing masks: slow walk, mean EtCO2 (mmHg) change +4.5 ± 2.4 versus +2.9 ± 2.3, P = .004; brisk walk EtCO2 change +8.4 ± 3.0 versus +6.2 ± 4.0, P = .009, with and without masks, respectively. Wearing masks was also associated with higher proportions of participant hypercarbia (EtCO2 range, 46-49 mmHg) compared with walking without masks” and “Sensations of difficulty breathing and shortness of breath were more common while walking with masks.”
Thus, real world studies conducted during the pandemic are signaling a warning that prolonged mask wearing causes a shortage of oxygen to the brain and unhealthy blockage of excretion of carbon dioxide waste from the body.
Both hypoxia and hypercapnia are known dangerous medical conditions, but if you have avidly followed the FAKE NEWS peddled by the mainstream media you will never have heard of such risks from masking up.
While it is proven that in severe cases death may result, the more insidious danger is the unseen, long term effects on our brains. Just spare a thought for the harm being inflicted on children ordered to wear these soiled rags all day in schools.
To clarify the dangers on a strictly objective scientific footing we looked to American Journal of Respiratory and Critical Care Medicine (Volume 186, Issue 12) and looked at

The study especially addressed the impacts of low oxygen on subjects who already have poor health due to respiratory impairment (Adult Respiratory Distress Syndrome).
