"Astronauts' Headaches: A Major Issue for Long Haul Space Missions"

A study involving 24 astronauts from various space agencies has revealed that headaches are more common in space travel than previously known, with 22 of the 24 astronauts experiencing headaches during their time aboard the International Space Station. The headaches varied in type and timing, with some resembling migraines and others tension headaches. The study suggests that the lack of gravity during space travel may lead to an increase in intracranial pressure, causing the headaches. This adds to the growing body of research on the effects of space travel on the human body, raising concerns for long-duration space missions.
