The mobilization of the body. What is our body in extreme conditions

How does the body react to the months spent in zero gravity, to the Arctic winter, to high air with a low oxygen content, to severe heat or lack of fluid? What comes from prolonged work underground or in conditions of microgravity and why do body temperature, blood pressure and pulse frequency change in such conditions relatively minimally? Specialist in space medicine and physiology Hanns Cristian Gung tells what happens to the human body with extreme physical and psychological stress. According to his authoritative opinion, in order to better understand the "unknown essence" of a person, a holistic approach is needed, which covers many areas of knowledge, from physiology and psychology to geology, astronomy, paleontology, and which at the same time always puts the human body in the center of attention.
"In this book I will talk about such studies that are carried out truly in adventure circumstances. We will get acquainted with the amazing adaptive capabilities of humans and animals, as well as with their physiological foundations that I will try to describe as an affordable and understandable language as possible, as far as they were still known at all. ” (Hanns Cristian Gung)
