A study of stress in flying during tropical summer, some physiological and biochemical changes in Indian pilots

Abstract

During this investigation attempts have been made to approach the general problem of flying fatigue in summer from both physiological and psychological aspects. This paper presents the result of physiological and biochemical changes. Changes in body weight, rectal temperature, haemotocrit value, blood glucose, and eosinophil count have been studied. Loss of body weight, increase in rectal temperature and haematocrit value did not give sufficient indication of hoemo concentration. The change in the level of blood glucose was also not very significant. Fall of eosinophil count was of the order of only 16-17 percent.
