A recent study published in the scientific journal Frontiers in Physiology revealed that astronauts experience temporary slowing of cognitive performance during their missions in space. The research team studied 25 astronauts who spent an average of six months on the International Space Station (ISS) and found that processing speed, working memory, and attention were slowed down during their time in orbit. Despite the slowing in response times, the astronauts maintained the same level of accuracy throughout the mission. These cognitive changes did not persist after the astronauts returned to Earth, although processing speed took longer to return to normal.
