Effect of spaceflight on the human body Effect of spaceflight on the human body Venturing into the environment of space can have negative effects on the human body. Significant adverse effects of long-term weightlessness include muscle atrophy and deterioration of the skeleton (spaceflight osteopenia). Other significant effects include a slowing of cardiovascular system functions, decreased production of red blood cells, balance disorders, eyesight disorders and a weakening of the immune system. Additional symptoms include fluid redistribution (causing the "moon-face" appearance typical in pictures of astronauts experiencing weightlessness), loss of body mass, nasal congestion, sleep disturbance, and excess flatulence.

European Society for the study of Human Evolution Max Planck Institute for Evolutionary Anthropology. The main goals of the society are to stimulate and facilitate communication and scientific collaboration between researchers and scientists involved in the study of human evolution, primarily through the organization of conferences, which are held annually in the second half of September. ESHE is dedicated to supporting activities which encourage new and innovative research in the field of human evolution, and is in particular supports the research of young scientists. Each year, ESHE hosts an annual meeting to showcase interdisciplinary research on human evolution from around the world. These meetings are held in the
