How much free time do you need to be happier？Feeling overwhelmed by your to-do list can certainly make you unhappy, but new research suggests that more free time might not be the magic elixir（灵丹妙药） like many of us have dreamed.

Researchers found that people with more free time generally had higher levels of subjective well-being（幸福） -but only up to a point. People who had up to two hours of free time a day generally reported they felt better than those who had less time. But people who had five or more hours of free time a day generally said they felt worse. “While too little time is bad, having more time is not always better,” said Marissa Sharif, an assistant professor of marketing at The Wharton School. For example, some adults struggle with the “retirement blues”, which can be due to a lack of stimulation and structure, among other things. They conducted several smaller online experiments. In one they asked participants to imagine having 3.5 to 7 free hours per day. They were asked to imagine spending that time doing “productive” things（like exercising） or to imagine doing “unproductive” activities (like watching TV).

Study participants believed their well-being would suffer if they had a lot of free time during the day-but only if they used it unproductively. “In other words, how people use their free time matters,” Sharif said. “Of course, what feels ‘productive’ is up to you. Free-time activities like knitting, reading, cooking or gaming are also known to put people in a state of flow. In cases when people do find themselves with excessive（过多的）amounts of spare time, such as retirement or having left a job,” Sharif said, “our results suggest these individuals would benefit from spending their newfound time with purpose.”
