Does cabin pressurization make you feel sleepier? Fact or myth? Let’s break it down! 🛫 It’s a fact! While the oxygen level in the air remains constant, cabin pressurization is set to simulate an altitude of 6,000–8,000 feet. At this altitude, the air density is lower, meaning your body absorbs oxygen less efficiently. This slight decrease in oxygen absorption can make you feel drowsy, especially on longer flights. #aviationfacts #flight #aviationdaily | Flywithcaptainjoe
