Space Travel Slows Cognitive Speed Without Lasting Effects
A NASA study published in Frontiers in Physiology reveals that astronauts experience slower cognitive performance in processing speed, working memory, and attention while in space, though accuracy remains unaffected. These changes do not persist after returning to Earth, suggesting no significant brain damage. However, the findings highlight potential challenges for long-duration space missions, such as those planned for the Moon and Mars, due to space's extreme stressors like radiation and microgravity. The study underscores the need for further research and strategies to mitigate space travel's cognitive impacts.
