Unless the mask is fairly airtight - and most of the fabric ones aren’t - then you’ll take in just as much air each time you breathe whether wearing a mask or not. The masks do not in any way reduce the amount of air entering your lungs.

It’s been debunked by several people that wearing a loose fitting fabric mask makes no difference whatsoever to the levels of oxygen you breathe in (which is what matters when inhaling).

Masks can be a bit stuffy and can make you sweat more - your basically going to have warm air around your face all day. They are a bit uncomfortable. But it won’t affect your breathing.
