The constellation of effects of space travel on human physiology, especially motion sickness; prolonged space flight is associated with osteoporosis, disuse muscle atrophy, growth of 5+ cm in space, related to low gravity, and may be punctuated by inconvenience—e.g., failure of waste management systems

Space sickness The constellation of effects of space travel on human physiology, especially, motion sickness Clinical Vertigo, N&V, GI dysmotility, malaise, diaphoresis, sialorrhea, yawning, anorexia, hyperventilation–resulting in hypocapnia with vasodilation of lower extremities and pooling of blood, causing postural hypotension and syncope; prolonged space flight is associated with osteoporosis, disuse muscle atrophy, growth of 5+ cm in space, related to low gravity, and may be punctuated by inconvenience–eg, waste management systems fail on most space flights.
