Mobilization of the Body. What Our Body is Capable of in Extreme Conditions

How does the body react to months spent in weightlessness, to the Arctic winter, to high-altitude air with low oxygen content, to intense heat or lack of fluids? What happens from prolonged work underground or in microgravity conditions, and why do body temperature, blood pressure, and pulse rate change comparatively minimally in such conditions? Specialist in space medicine and physiology Hanns-Christian Gunga explains what happens to the human body under extreme physical and psychological loads. In his authoritative opinion, to better understand the 'unknown essence' of a person, a holistic approach is needed that encompasses many fields of knowledge, from physiology and psychology to geology, astronomy, paleontology, and that always places the human body at the center of attention.
