Mice Anxiety Levels Reset After Wild Exposure

Scientists from Cornell University did a study where they let 44 lab mice run free in a big outdoor space.

After just one week, the mice's anxiety levels went back to normal.

The scientists think this happened because the mice had more different experiences in the wild.

They used a special maze to test the mice's anxiety.

Normally, mice are scared of open spaces in the maze, but the mice that were in the wild explored both open and closed spaces equally.

The scientists think this shows that having lots of different experiences can help reduce anxiety.

They also think that the environment might be more important than biology in causing anxiety.

This study could help us understand anxiety in humans too.
