Space adaptation syndrome
Space adaptation syndrome (pronunciation: /speɪs ædæptəˈteɪʃən ˈsɪndroʊm/) is a condition experienced by astronauts during the adaptation to microgravity in space. It is characterized by symptoms similar to motion sickness on Earth, including nausea, vomiting, pallor, sweating, malaise, and loss of appetite.
Etymology
The term "space adaptation syndrome" was coined by NASA in the early 1970s. The word "space" refers to the outer space environment, "adaptation" refers to the process of adjusting or acclimating, and "syndrome" refers to a group of symptoms that consistently occur together.
Symptoms
The symptoms of space adaptation syndrome can vary in severity from mild to severe and can last for up to 72 hours. They include:
Causes
Space adaptation syndrome is caused by the changes in gravity that occur when moving from the Earth's gravitational pull to the microgravity environment of space. This change affects the vestibular system, which is responsible for maintaining balance and spatial orientation.
Treatment
Treatment for space adaptation syndrome primarily involves symptom management. Medications such as promethazine and scopolamine may be used to control nausea and vomiting. In addition, astronauts are encouraged to move slowly and avoid sudden head movements to help reduce symptoms.
