Abstract

Human movements in extremely hostile environment like humid costal areas, frigid high altitude lead to detrimental physiological effects. It is unavoidable due to military, sports, piligrimages and tourism activities. High altitude is one of the most extreme environments creating challenges to human survival and performances. Travel to high altitude exposes the human body to a variety of stresses, the most prominent being reduced oxygen level with increase in altitude due to reduced partial pressure of oxygen. The physiological changes like hypoxic ventilatery response, diueresis, increased cardiac output, improved oxygen carrying capacity and cerebral blood flow etc. occurs during high altitude exposure. This article reveals basic framework mentioned above.
