[Blood system reactions in flight operators with high and low levels of anxiousness during geomagnetic disturbances]

Under the same flight conditions hemoglobin content as well as amounts of red and white blood cells have been shown to be less while reticulocyte count and coagulation rate higher in operators with elevated levels of anxiety than in their counterparts. During geomagnetic disturbances hemoglobin content and red and white blood cell counts in these subjects have been reduced to even greater extent. Microcirculatory homeostasis was activated, coagulation time reduced and reticulocyte count grew larger. Geomagnetic disturbances did not cause any alterations in blood pictures of the flight operators with low levels of anxiety while (under standard flight conditions) their hemoglobin, red and white blood cell counts were higher than in operators with elevated anxiety implicating greater compensatory potentialities of the homeostatic systems.
