The fluid shift hypothesis suggests that space motion sickness results from the headward shifting of body fluids induced by the loss of hydrostatic pressure in the lower part of the body when entering microgravity. Motion sickness most likley occurs when the stimuli applied to these receptors appear to be in conflict. This means that these symptoms are not caused by weightlessness as such, but more generally by adaptation to a different gravitational force. Dizziness, nausea, vomiting, pale or sweaty face can be seen in children. The former occurs when one perceives visually that one’s surroundings are relatively immobile while the vestibular system reports that one’s body is in motion relative to its surroundings . Space sickness was mostly unknown during the first spaceflights because astronauts were in extremely cramped conditions.
