“We found that people who are on average more physically active are also on average happier,” says study co-author Gillian Sandstrom, Ph.D., lecturer at the University of Essex. “And when people are more physically active than usual, they also report being happier than usual.”
These results were true both when the activity was self-reported and when it was sensed from the accelerometer on users’ phones. Activity was broadly defined as walking, running, and cycling.
