Smile for your smartphone: Snapping selfies can help boost your mood, a new study from the University of California at Irvine found.
Researchers divided participants into three groups and instructed them to take one photo each day for three weeks.
The first group snapped smiling selfies, the second captured images that made them happy, and the third took photos that they thought would make someone else happy, which they then sent to that person.
The people in each group experienced boosts in their mood overall, but other specific benefits depended on what they were snapping.
