OK I've got a bone to pick. I've read this below from some medical article and in my opinion there' just NO WAY this can be true. Opinions welcome!
MYTH: Wearing a mask causes you to inhale too much carbon dioxide, which can make you sick.
FACT: Wearing a cloth mask will not cause dizziness, lightheadedness, and headaches (also known as hypercapnia or carbon dioxide toxicity). Carbon dioxide passes through the mask, it does not build up inside the mask. If you feel dizzy or get a headache, you may be dehydrated since wearing a mask doesn’t make it as easy to drink water. We recommend keeping yourself very hydrated.
Debunking common face mask misconceptions
Now look. The only time I wear a mask is entering a store. Whatever amount of liquids I've ever drank HAS NOT changed because of covid. If this were true that the only reason I feel dizzy or lightheaded is because I haven't drank much water or am dehydrated wouldn't I have experienced that all other times? Surely I would have!
But usually about 6 minutes in a store I experience a dizzy lightheaded feeling and this medical piece wants to suggest it's not because I'm wearing a mask? If I could borrow a term by Joe Biden,
"Come on MAN!" My wife has the same thing happen to her as well. Talked to others....THE SAME! So what is it with this thing that they're trying to talk people out of things they down right KNOW are facts?!
Look I know what water dehydration dizziness is like. I worked years ago in buildings which didn't have any air conditioning in heat waves and I know what that can be like. This is nothing like that when wearing a mask. So it has to be oxygen depletion or something like that taking place by wearing the mask.
