UVM study suggests a walk in the park to lift your mood

BURLINGTON, Vt. (WCAX) If you're in a cranky mood, you should try a walk in the park.

Scientists at the University of Vermont found people who visit urban parks use happier words on Twitter than before their visit.

The study says the mood lift can last for up to four hours.

Researchers found that the increase of happiness from a visit outside is equivalent to the mood spike on Christmas.
