Why? To put it bluntly, beauty is health.
That's right. Traditional beauty—the outer kind—serves as a proxy of how healthy you are. It's the message you send to others about your health. Simply, beauty is an instant message to others that transmits youth, fertility, and health. That's why beauty is an extremely important evolutionary cue. Not convinced? Look at traditional images of ugly things—pus, blood, gore. They almost always correlate with something unhealthy.
Now, that's just talking about outer beauty. Inner beauty—the idea of feeling good and being happy—also has tremendous health implications in every aspect of your life.
