I have been having severe headaches after flying lately.  Being masked on an airplane and duty day that are now on average 10-15 hours a day.  I had a deadhead recently and wore an oxygen sensor from start to finish.  My oxygen in the hotel was 99/98 on the pulse oximeter.  During the flight from ZZZ to ZZZ1 I wore it the whole time.  My oxygen was between 89 and 94 the whole way until landing.  It then was back up to 98; 20 minutes after landing.  It is a fact that extra oxygen is pumped into hospital rooms during long surgeries because the doctors are masked.  I feel this shows that lack of oxygen; just on 1 flight is proving how I'm getting my headaches; let alone being masked as well.  I have never felt more unsafe flying than I have since having to wear masks.
Flight Attendant reported the requirement to wear a mask during flights is resulting in having low blood oxygen levels and associated headaches.
