Astronauts more likely to experience headaches in space than previously known, study finds

A newly published study in the field of space medicine has revealed that astronauts are more prone to headaches during space missions than previously known.

This was a larger proportion than the researchers had expected based on prior anecdotal evidence. The headaches - some resembling migraines and others resembling tension headaches - occurred not only during the first couple of weeks in space as the body goes through the process of adapting to microgravity, but also later.
