Did your mother ever say you'll feel better after a good cry? It turns out Mom is right as usual-crying really is healthy. What's more, letting yourself feel blue and accepting those feelings will help you feel better in the long run, according to a new research.

In three separate studies both online and in a lab, researchers at UC Berkeley evaluated the responses from 1,300 adults regarding their psychological(心理的)health and emotional well-being(幸福感).In one study,1,000 participants filled out a survey evaluating how they felt about the statement, "I tell myself I shouldn't be feeling the way that I'm feeling." Those who agreed with the statement scored lower on tests of well-being. In other words, letting yourself feel bad is better for your mind and mood than trying to control negative thoughts.

"We found that people who habitually accept their negative emotions experience fewer negative emotions, which adds to better psychological health," said study senior author Iris Mauss, PhD, an associate professor of psychology at UC Berkeley in an article on the university's website.

In a society where the importance to be happy is emphasized daily on the other social media platforms, letting yourself be down in the dumps can be tough. Just remember that true happiness isn't always what people say it is.

"It turns out that how we approach our own negative emotional reactions is really important for our well-being," said study lead author Brett Ford, PhD, an assistant professor of psychology at the University of Toronto. "People who accept these emotions without judging or trying to change them are able to deal with their stress more successfully."

So next time someone tells you to "turn that frown upside down", ignore them. Embrace your inner feelings for a while.
