Space Travel Alters Astronauts' Brain Position

Space Travel Alters Astronauts' Brain Position

Scientists found that astronauts' brains shift upward and backward inside their skulls when they go to space.

This happens because of the lack of gravity.

The changes can make astronauts feel dizzy and unbalanced.

Most of the changes go back to normal after about six months on Earth, but some changes last longer.

The study also found that the longer astronauts stay in space, the more their brains shift.

Scientists think this is important for future space missions to the Moon and Mars.

They need to understand these changes to keep astronauts safe and healthy.

The study used brain scans from astronauts and people who stayed in bed for a long time to simulate space conditions.

The researchers say more studies are needed to fully understand how space affects our brains.
