There's evidence that masks don't work to prevent COVID spread at all:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7680614/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7680614/
"A meta-analysis among health care workers found that compared to no masks, surgical mask and N95 respirators were not effective against transmission of viral infections or influenza-like illness based on six RCTs.
"Using separate analysis of 23 observational studies, this meta-analysis found no protective effect of medical mask or N95 respirators against SARS virus."
"A recent systematic review of 39 studies including 33,867 participants in community settings (self-report illness), found no difference between N95 respirators versus surgical masks and surgical mask versus no masks in the risk for developing influenza or influenza-like illness, suggesting their ineffectiveness of blocking viral transmissions in community settings."
Masks also make breathing more exhausting:
"Wearing facemask mechanically restricts breathing by increasing the resistance of air movement during both inhalation and exhalation process"
"trapped air remaining between the mouth, nose and the facemask is rebreathed repeatedly in and out of the body, containing low O2 and high CO2 concentrations, causing hypoxemia and hypercapnia"
Being forced to wear something which is ineffective and physically exhausting could absolutely cause burnout.

- ArkanExplorer 5y agoOk, you're right, at least based on this article: http://rc.rcjournal.com/content/55/5/569.short http://rc.rcjournal.com/content/55/5/569.short Which showed no difference in O2 or CO2. However, there is still the physical and psychological element of wearing PPE/respirators everyday which is burdensome.
- bitexploder 5y agoThe risk of catching a deadly infectious disease is the burden... masks mitigate the risk. Is it comfortable no? It’s a constant reminder of your workplace hazards. What are you even trying to argue?
- ArkanExplorer 5y agoThe average age of a nurse (in the UK) is about 45. Taking the average weight and height of an average woman (in the UK), and assuming the person is otherwise healthy, the risk of COVID hospitalization is 1 in 3000, and risk of death 1 in 66,000 This is from the UK's own data: https://www.qcovid.org/Calculation https://www.qcovid.org/Calculation There are 670,000 nurses in the UK, so if all of them got COVID, 223 of them would need hospitalisation, and 10 would die. Admittedly this is a simple extrapolation and doesn't account for the risk to older nurses. By contrast with a general population of 670,000 women in their 40-50s, about 1600 will die each year from any cause: http://www.bandolier.org.uk/booth/Risk/dyingage.html http://www.bandolier.org.uk/booth/Risk/dyingage.html
