Motion sickness: Can it be controlled

Abstract

NASA is one of the few research centers concerned with motion sickness. Since the physiology of man has been developed in the one-gravity field Earth, the changes experienced by man in space are unique, and often result in symptoms that resemble motion sickness on Earth. NASA is concerned with motion sickness because it is very uncomfortable for the astronauts. Another concern of NASA is the possibility of a motion sickness astronaut regurgitating while he or she is sealed in an airtight space suit. This could be fatal. Motivated by these reasons, NASA spent thousands of dollars in research and development for a drug or technique for combating motion sickness. Several different treatments were developed for this disorder. Three of the most effective ways of combatting motion sickness are discussed
