Space medicine is a field of medicine that focuses on the health and well-being of astronauts during space travel. It addresses the unique challenges posed by microgravity, radiation exposure, and the isolation of space environments. Researchers study how these factors affect the human body and develop strategies to prevent and treat potential health issues. To ensure astronauts can perform their missions safely, space medicine includes monitoring physical and mental health, providing medical training, and creating emergency response plans. This discipline also contributes to our understanding of human biology, which can benefit healthcare on Earth as well.
