Flight Physiology

Flight physiology refers to how the human body responds to the physical challenges of flying, particularly at high altitudes. As altitude increases, air pressure decreases, leading to less oxygen availability, which can cause hypoxia (lack of oxygen). This affects our ability to think clearly and can induce fatigue. Additionally, the lower pressure can cause gases in our bodies to expand, leading to discomfort. Pilots and frequent flyers may experience changes in circulation and fluid balance, necessitating measures like staying hydrated and gradually acclimatizing to altitude. Understanding these effects helps ensure safety and comfort during flight.
