Scientists in Japan have been studying the effects of running on mood and brain function. Their results show that a short run can help improve both.
The increased blood flow to the brain helps boost the prefrontal cortex, which plays an important role in both mood and executive functions that are controlled in this portion of the brain.
Results of the tests indicated that after running, participants showed an increase in pleasure and arousal and they answered questions faster with increased brain signals.
There were only a small number of participants, so further testing is needed to verify the findings.
