more bold on what I've been saying

According to the reported clinical observation study by Samannan et al.,101 the wearing of facemasks neither significantly restricted the gas exchange (oxygen circulation) nor contributed to carbon dioxide buildup, even in persons with severe lung impairment.
Nevertheless, prolonged use of facemasks has some side effects on human respiratory health, such as thermal stress, drowsiness, breathing problems because of restricted fresh airflow, and unusual heart rate.102,103 The discomfort felt with surgical mask use has also been ascribed to neurological reactions or associated psychological phenomena such as anxiety, claustrophobia, or affective responses to the perceived difficulty in breathing.101 In addition, if a facemask is donned for a longer period, the filter gets wet because of facial sweat, and vapor is formed inside the facemasks due to the breathing, resulting in clogging of particulates. In addition, wearers get a false sense of security, encouraging them to spend more time in public places.104 Other potential side effects of facemasks’ wearing include skin irritation, uncomfortable feeling due to the arrival of exhaled air into the eye, comprised quality, and the volume of the speech during the conversations.19,105,106

That last bit I hadn't really thought too far on. That when talking with a surgical mask on you have to almost shout thru the mask.
