Using data from two national surveys, the researchers found that participants' negative emotional responses to stress could be used to predict psychological distress and self-reported anxiety ten years later.
"How we manage daily emotions matters to our overall mental health," Professor Charles said.
"We're so focused on long-term goals that we don't see the importance of regulating our emotions.
"Changing how you respond to stress and how you think about stressful situations is as important as maintaining a healthy diet and exercise routine."
The results were based on data from 711 men and women between the ages of 25 and 74.
According to Professor Charles and her colleagues, the findings showed that mental health outcomes are not affected by just major life events - they are also influenced by the impact of seemingly minor emotional experiences.
"It's important not to let everyday problems ruin your moments," Professor Charles said.
"After all, moments add up to days, and days add up to years.
"Unfortunately, people don't see mental health problems as such until they become so severe that they require professional attention."
