When did you last feel awe? This is Science Today. Psychologist Dacher Keltner of the University of California, Berkeley, directs the Berkeley Social Interaction Laboratory, which focuses on emotion, morality, power and culture. Keltner is now looking into how feelings of awe affect us.

"When we ask people, they’ll say, “when I first saw Notre Dame” or “when I went to Yosemite” – just all these experiences, it’s just this incredibly fertile area of human experience and people say that these experiences changes their lives."

And now Keltner’s lab is finding that feelings of awe actually reduce the body’s inflammation response.

"It’s because of how it changes your immune profile, so we are in conversation with programs that take stressed-out kids to the woods and now we can have a sense of the benefits that will arise out of that. So it’s really exciting."
