Recent research suggests that experiencing not-so-happy feelings actually promotes psychological wellbeing. A study published in the journal Emotion in 2016 took 365 German participants aged 14 to 88… The team found that the link between negative mental states and poor emotional and physical health was weaker in individuals who considered negative moods as useful. Indeed, negative moods correlated with low life satisfaction only in people who did not perceive adverse feelings as helpful or pleasant.
