QUESTION ADDRESSED In contrast with pain, dyspnoea is not visible to the general public who lack the corresponding experiential baggage. We tested the hypotheses that the generalised use of face masks to fight SARS-CoV2 dissemination could change this and sensitise people to respiratory health. METHODS General population polling (1012-person panel demographically representative of the adult French population -quota sampling method-; 517 women, 51%). 860 (85%) answered "no" to "treated for a chronic respiratory disease" ("respiratory healthy", RH) and 152 "yes" ("respiratory disease", RD). 14% of RH respondents reported having a close family member treated for a chronic respiratory disease (RH-family+ and RH-family-). Respondents described mask-related attitudes, beliefs, inconveniencies, dyspnoea, and changes in their respiratory health vision . RESULTS: Compliance with masks was high (94.7%). Dyspnoea ranked first among mask inconveniencies (RD 79.3%, RH 67.3%, p=0.013). "Air hunger" was the main sensory dyspnoea descriptor. Mask-related dyspnoea was independently associated with belonging to RH-family+ (Odds Ratio [OR] [95% confidence interval (CI)]: 1.85 [1.16-2.98]) and removing masks to improve breathing (OR 5.21 [3.73-7.28]). It was negatively associated with considering masks effective to protect others (OR]: 0.42 [0.25-0.75]). Half the respondents were more concerned with their respiratory health since wearing masks; 41% reported better understanding patients' experiences. ANSWER TO THE QUESTION Wearing protective face masks leads to the mass discovery of breathing discomfort. It raises the public's awareness of what respiratory diseases involve and sensitises to the importance of breathing. These data should be used as the fulcrum of respiratory-health-oriented communication actions.
