Does wearing a mask in high humidity make it harder to breathe, and if so, how to prevent passing out?

Mask: Wearing a mask can be a little uncomfortable. You may find yourself sweating more under the mask. You can experiment with wearing a face cover (like a scarf) or if your mask is overly-tight on your face, get one which isn't squeezing you so much. I have been making them by hand and modifying designs for people with special needs. Different masks will have different comfort levels.
