My immediate question would be;
What about the millions of health experts that have to wear them all day in hot and human conditions?
Why didn't/don't they get health warnings like this?

#FactFriday - Non-medical masks or cloth face coverings can make breathing difficult in high heat & humidity.

Did you read the bit that says 'non medical masks'?

I still have this stupid virus and it’s been more than two weeks and it is no fun.
I live outside Las Vegas and on Monday I go in for the phase 3 trial of a vaccine.

Did they give a reason why they were giving you a vaccine if you've already had it for two weeks? That doesn't seem like a viable way to do a clinical trial of a vaccine.

Although the protective mechanisms of respirators (masks) are largely physical and sometimes chemical, wearing respirators come with a host of physiological and psychological burdens.
Methods: A surgical mask was worn over an N95 filtering facepiece respirator by 10 healthcare workers for 1 h at each of two work rates. Heart rate, respiratory rate, tidal volume, minute volume, oxygen saturation, transcutaneous carbon dioxide levels and respirator dead space gases were monitored and compared with controls (N95 filtering facepiece respirator without a surgical mask). Subjective perceptions of exertion and comfort were assessed by numerical rating scales.
Results: There were no significant differences in physiological variables between those who used surgical masks and controls. Surgical masks decreased dead space oxygen concentrations of the filtering facepiece respirators at the lesser work rate (P = 0.03) and for filtering facepiece respirators with an exhalation valve at the higher work rate (P = 0.003). Respirator dead space oxygen and carbon dioxide levels were not harmonious with Occupational Safety and Health Administration workplace ambient atmosphere standards. Exertion and comfort scores were not significantly impacted by the surgical mask.
Conclusions: Use of a surgical mask as an outer barrier over N95 filtering facepiece respirators does not significantly impact the physiological burden or perceptions of comfort and exertion by the wearer over that experienced without use of a surgical mask.
