Like on Earth, humans are not immune to motion sickness, even in space. This is why some astronauts may experience the 'Space Adaptation Syndrome (SAS)' in outer space. "It is a condition experienced by various astronauts when they enter space. The sudden transition from Earth’s gravity to space poses several physical and physiological effects on an individual’s body. This can include a range of symptoms that can cause discomfort, including nausea, dizziness, headache, and feeling extremely tired," said Dr Anup Khatri, senior consultant, orthopedics, Gleneagles Hospital, Parel, Mumbai. The main reason that can contribute to this syndrome is the fact that the body may need some time to "get adjusted to the microgravity environment in space." "However, you and your body may get used to all the differences in space within a week or two. But the first few days can be stressful and overwhelming," elucidated Dr Khatri. Dr Swapnil M Khadake, HOD, and consultant critical care, Fortis Hiranandani Hospital Vashi called it "space sickness that happens to astronauts due to the effects of reduced or zero gravity, leading to temporary impairment of the body's vestibular orientation and balance functions". "The vestibular system, located in the inner ear, detects gravity and helps orient the body for balance. Thus, SAS symptoms are similar to motion sickness like vomiting, nausea, headache, giddiness, weakness, etc," explained Dr Khadake. To effectively manage SAS and its symptoms, simple antiemetics medicines like promethazine and scopolamine, which help treat nausea, can be used, said Dr Khadake. "One should also rest properly, avoid sudden jerks in head movements, and drink sufficient fluids to avoid dehydration," he added. Dr Khatri elaborated that astronauts about to go into space are given gradual exposure by training them in simulators that mimic the microgravity environment in space. "This can help them prepare their mind and bodies to get used to this sudden change. Practicing the breathing-relaxing technique can help keep you calm and composed. Astronauts need to remember that the adaption time may vary from person to person. Some may feel better with a few days, whereas some may need a week or more to adjust. It becomes crucial to stay patient," said Dr Khatri. SAS typically resolves within a few days. "Taking precautionary measures, such as keeping medications on hand and monitoring daily activities, can be beneficial," said Dr Khadake.
