To what extent does flying work affect health?

Flight activities are carried out under the conditions of high altitude, high speed, heavy load and fast pace. If some measures are not taken, it will have a great impact on people's health. Modern aircraft are equipped with many devices that can eliminate and reduce the adverse effects and reactions on pilots, so the working environment of pilots is greatly improved. If the air at high altitude is thin and the oxygen is reduced, people will have difficulty breathing, headache, dizziness, palpitation, nausea, and will seriously lose consciousness when lacking oxygen. The problem of high altitude hypoxia is solved by installing oxygen equipment on the plane and wearing oxygen masks for pilots over 4000 meters. For another example, the drop in air pressure at high altitude will cause problems such as decompression sickness and flatulence at high altitude. The method of cabin sealing and cabin pressurization is adopted to reduce the air pressure at high altitude, thus eliminating or reducing the impact on human body. The acceleration and load of fighter will make people bear great centrifugal force, and head ischemia will cause gray vision or black vision. Pilots wearing anti-load suits and adopting scientific and effective physiological countermeasures can greatly enhance their anti-load ability and reduce or eliminate cerebral ischemia. In a word, the various effects of flight on human body have been basically solved in modern aircraft, so flight has no effect on human health and life. As for flying activities, fast-paced training is easy to cause energy consumption and fatigue, which varies from person to person. As long as you keep exercising, combine work and rest, and recover quickly, you can solve it by taking a rest after flying. According to the physiological indexes such as oxygen consumption, heartbeat and breathing times, flying activities are only equivalent to moderate intensity activities.
