Physiological Responses in Air Traffic Control Personnel: Houston Intercontinental Tower,
CIVIL AEROMEDICAL INST OKLAHOMA CITY OKLA
Pagination or Media Count:
Biochemical and physiological indices of stress showed that the level of stress of 16 air traffic controllers at the Houston Intercontinental Airport Tower was indistinguishable from that of control populations. While the level of stress was lower than that among OHare Tower controllers, both groups showed about the same degree of adaptation. Day work heavy traffic load at Houston was characterized by elevated levels of all stress indicators as compared with the mid-shift light traffic epinephrine excretion increased significantly during the last half of the mid-shift as compared with the first half. Urinary stress indicators 17-ketogenic steroids, epinephrine, norepinephrine were all significantly elevated during day sleep as compared with night sleep, indicating less effective rest during day sleep.
