With greater physical exertion comes the experience of more positive emotion
One researcher surveyed the emotions of two ultra-runners. They ran for a 10-week period and covered 3641 kilometers (2262 miles) across Europe. The route included a variety of terrain including flats and mountain ranges such as the Pyrenees.
Researchers found the following:
-the more physical exertion they expended, the more their mood intensified
-four key factors: mental stamina, motivation to test one’s limits, friendliness with their partner, and self-awareness
The results of the test showed: when people do amazing things, they feel more energetic in other areas of their lives.
