Space adaptation syndrome (more commonly called space sickness) is a condition experienced by individuals during space travel.
Ezri Dax experienced space sickness occasionally during space travel, after she was joined with the Dax symbiont. Ezri thought she could actually feel the rotation of Deep Space 9, a movement that made her ill. (DS9 episodes: "Shadows and Symbols", "Afterimage", "Prodigal Daughter", "Penumbra")
