The article discusses the physiologic changes that happens among the astronauts during their short- and long-duration space flight. It examines the relationship between space physiology and medicine that has contributed to the human space flight in the first half century. It explores the medical problems associated with short-duration space flight, its countermeasures, and the delivery of medical care. It discusses the use of the term acclimation and acclimatization with regards to the psychological and physiologic responses to short and long term exposure in the space-flight environment. Moreover, it defines microgravity and its effect on human physiology.

Potentially, this technique could inhibit bone loss during long-duration spaceflight and be an effective treatment for...

    Orthostatic intolerance is common after space flight and head-down tilt (HDT) bed rest. We hypothesized that HDT-induced impairments of arterial blood pressure (AP) control would be more marked during exercise and that recovery of baroreflex function after very long-term HDT would be delayed....

    Purpose: In space, astronauts are subject to microgravity, which reduces skeletal loading and osteoblast function and can cause bone resorption and a decrease in bone density. No known research to date has studied the effect of microgravity on dental implants. This study evaluated peri-implant...

    Dry immersion, which is a ground-based model of prolonged conditions of microgravity, is widely used in Russia but is less well known elsewhere. Dry immersion involves immersing the subject in thermoneutral water covered with an elastic waterproof fabric. As a result, the immersed subject, who...
