Feeling anxious? Try going for a jog or working out. Scientists have found that the human brain can be remodeled by exercise to reduce anxiety.

FOX News Radio's Steve Knight reports:

Researchers at Princeton found that exercise creates what they call 'excitable' brain cells, which are very good at helping us think and remember things. But, those same cells also create anxiety. The two seem incompatible and researchers were puzzled. So, the scientists started testing mice using running wheels to make them fit and ice water baths to make them anxious. They found that the running mice's new brain cells also released a chemical that calms emotions.
