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.
