During cruise; we ended up circling for over 30 minutes due to a thunderstorm on the field in ZZZ. The airport was closed and we were holding. During this time; my C Flight Attendant and I started feeling dizzy. We both attributed this to the burden of wearing a mask the entire flight. Fortunately in descent; we both started to feel normal; but it was unsettling to think about what could have happened if 2 out of 3 of us became ill during the flight. On a side note; when working C it is impossible to properly brief the exit row passengers without taking a mask partially off one's face. The customers cannot hear us; understand us; and as I previously reported; I had to remove a passenger from the exit row because it was impossible to tell how old he was with his face covered up.Masks cannot be feasibly worn for 7-10 hour duty days. Masks only need to be worn during boarding; deplaning and walk throughs. This is becoming a huge safety issue.
Flight Attendant reported feeling dizzy along with another Flight Attendant and attributed it to having to wear a protective mask.
