Studies suggest “micro awe” experiences (like gazing at a reflection on the water or visiting a nostalgic playground) improve wellbeing and mental health. Dacher Keltner, a professor of psychology at the University of California, leads a team of researchers who study the effects of awe on the human body. In one study, a group of 60 participants, were asked to go on 15-minute “awe walks” each week and take pictures. The study found relative to a control group, the awe-oriented participants “reported greater joy and prosocial positive emotions.” They also tended to smile more over time.
