A team of Californian researchers, led by Susan Charles, recently published a study linking daily hassles to depression (Charles et al., 2013). A group of just over 700 participants were studied for eight consecutive days. On each day they reported daily hassles and also how negative they were feeling. Ten years later the same participants were re-assessed. The researchers found that those participants who experienced negative emotions on days with high levels of daily hassles were more likely to be depressed. This suggests that people who are stressed by their daily hassles are more likely to suffer from mental health issues later in life.
