I read that you can get pleurisy if you wear a face mask for too long. Is that correct?


No – you will not get pleurisy, an inflammation of the tissue around the lung, by wearing a face mask for too long. There have been several other myths like this in circulation around masks and carbon dioxide and oxygen levels too. The WHO says that while the prolonged use of medical masks may be uncomfortable, it does not lead to breathing in too much of your own carbon dioxide, nor cause oxygen deficiency. However, you should not re-use disposable masks, and make sure you change it if it becomes damp.
