SAS usually goes away after a week or two because the body needs time to acclimatise to the microgravity environment.

In microgravity, the inner ear's vestibular system, which regulates balance, is momentarily compromised, resulting in motion sickness-like symptoms as giddiness and vomiting.

Using antiemetic drugs such as scopolamine and promethazine, resting, minimising abrupt head movements, and drinking plenty of water are all part of managing SAS.

To assist their bodies and minds adjust to the changes they would encounter in space, astronauts train in simulators that replicate microgravity before to travel.

SAS can be lessened and a speedier recovery can be achieved by using relaxing techniques, exercising patience, and taking preventative steps like keeping drugs on hand.
