Health Question

I know I am asking a ton of questions here but I just have a question about health and shaping. I have been wearing a mask that covers eyes/mouth for the whole shpaing process but I took it off and shaped the nose wityhout 1 for about an hour because my mask was gettting fogghed up. My throat kinda feels weird, should I be really concerned?

when cutting foam

a dust mask will be semi adaquate

resperator is the best

i think youll live
