Greater Good online magazine has an intriguing piece that investigates the downside of being "too happy." Reviewing recent research, the author determines that our nonstop drive to find the holy grail of happiness comes at a cost. From the piece:
Happiness, it turns out, has a cost when experienced too intensely.
For instance, we often are told that happiness can open up our minds to foster more creative thinking and help us tackle problems or puzzles. This is the case when we experience moderate levels of happiness. But according to Mark Alan Davis’s 2008 meta-analysis of the relationship between mood and creativity, when people experience intense and perhaps overwhelming amounts of happiness, they no longer experience the same creativity boost. And in extreme cases like mania, people lose the ability to tap into and channel their inner creative resources. What’s more, psychologist Barbara Fredrickson has found that too much positive emotion—and too little negative emotion—makes people inflexible in the face of new challenges.
Not only does excessive happiness sometimes wipe out its benefits for us—it may actually lead to psychological harm. Why? The answer may lie in the purpose and function of happiness. When we experience happiness, our attention turns toward exciting and positive things in our lives to help sustain the good feeling. When feeling happy, we also tend to feel less inhibited and more likely to explore new possibilities and take risks.
