So...all I had to do was type in the name of the author of this “study”.

And since you are going to disagree with politifact for being leftist.

This article is literally being used as a method to teach people about how to identify misinformation.

Who has the mask on for 4 hours straight?

Presumably pilots 🤷🏼‍♂️

You’re not going to be spending 4 hours at Walmart. At least I hope not!

Pretty much everyone that has to be around customers and wear a mask for work.

Yep, so a different website with a different political agenda says this is all fake science - OK, but do we ever ask why? Did you check any of the citations in the article to see if they did in fact support the authors claims of masking having health impacts? Like this piece, an actual RCT study done before COVID:

The physiological impact of wearing an N95 mask during hemodialysis as a precaution against SARS in patients with end-stage renal disease

Methods: ESRD patients who received regular HD at National Taiwan University Hospital between April to June 2003 were enrolled. Each patient wore a new N95 mask (3M Model 8210) during HD (4 hours). Vital signs, clinical symptoms and arterial blood gas measured before and at the end of HD were compared.

Results: Thirty nine patients (23 men; mean age, 57.2 years) were recruited for participation in the study. Seventy percent of the patients showed a reduction in partial pressure of oxygen (PaO2), and 19% developed various degrees of hypoxemia. Wearing an N95 mask significantly reduced the PaO2 level (101.7 +/- 12.6 to 92.7 +/- 15.8 mm Hg, p = 0.006), increased the respiratory rate (16.8 +/- 2.8 to 18.8 +/- 2.7/min, p < 0.001), and increased the occurrence of chest discomfort (3 to 11 patients, p = 0.014) and respiratory distress (1 to 17 patients, p < 0.001). Baseline PaO2 level was the only significant predictor of the magnitude of PaO2 reduction (p < 0.001).

Conclusion: Wearing an N95 mask for 4 hours during HD significantly reduced PaO2 and increased respiratory adverse effects in ESRD patients.

Sure, nothing I would want to call completely conclusive, but it is valid and does support the authors contention. Why are you (and politifact) so quick to throw that out? Do you only believe the science that supports your preconceived notions then?
