When people get up and move, even a little, they tend to be happier than when they are still, according to a new study that used cellphone data to track activities and moods. In the study, which was published in PLoS One, researchers at the University of Cambridge in England developed an app that randomly sent requests to people throughout the day, asking them to enter an estimation of their current mood. At the same time, the app gathered data from the activity monitor that is built into almost every smartphone today. In general, the researchers found, people who move are more content than people who sit.
