"Astronauts' Headaches: A Major Challenge in Space Travel"

A new study has found that astronauts are more likely to experience headaches in space than previously known, with 22 out of 24 astronauts reporting headaches during their time aboard the International Space Station. The headaches, some resembling migraines and others tension headaches, occurred not only during the initial adaptation to microgravity but also later in the mission. The study suggests that different mechanisms may be involved in early and later headache episodes, with potential causes including space adaptation syndrome and increased intracranial pressure due to fluid accumulation in the upper body and head.
