ABSTRACT
In relation to the aircrew's professional activity, it is commonly known that this activity is undertaken inside an artificial environment, where the individual is supposed to be adapted to the machine. In spite of being fully prepared to act in this quite unusual environment where they spend most of their time "in the air, inside flying machines", the aircrews suffer the influences of physical agents. The complaints about the humor, irritability, depression and other disturbances like stomach-ache, headache, lack of appetite, and muscular pain, among others are reported by them as symptoms caused by the constant adaptations that their body must make. According to Seligman-Silva, the symptoms caused by these constant adaptations may vary a lot, depending on the individual's resistance to fatigue. However, when it becomes chronic and starts to be part of the aircrew's life, it will interfere in his personal relationships and cause serious conflicts.
