Abstract in brief

The study investigates how sleep quality and pressure are affected in astronauts during their 6-month space missions, revealing increased sleep pressure indicated by specific brain activity markers such as theta oscillations and global sleep-like events.
Results show that astronauts experience more sleep pressure in space compared to Earth, which correlates with slower reaction times and impaired performance during tasks like spacecraft docking.
These findings highlight the importance of monitoring sleep quality in space to ensure astronauts maintain alertness and cognitive skills, as increased sleep pressure could negatively impact visuomotor performance during missions.
