(Cover) – EN Fitness & Wellbeing – Sweating over the small stuff can lead to chronic diseases in later life, new research has found.

It’s easy to get wound up day-to-day, whether you rage over a parking ticket, or brood over an argument with a friend or family member.

But a new study has discovered that people who dwell on mundane stressors for over 24 hours have much weaker immune systems and more heart problems 10 years down the line.

Researchers from the University of California, Irvine analysed 1,155 people across America who took part in the Midlife in the United States Survey, where they were asked about the daily stressors they had experienced across eight consecutive days, and the effect they had on them. Participants were then quizzed again a decade later.

The team found that fretting over a flat tyre, bad grade or argument for more than a day has a negative impact on someone’s health.

“Our research shows that negative emotions that linger after even minor, daily stressors have important implications for our long-term physical health,” author Kate Leger commented. “When most people think of the types of stressors that impact health, they think of the big things, major life events that severely impact their lives, such as the death of a loved one or getting divorced.

“But accumulating findings suggest that it’s not just the big events, but minor, everyday stressors that can impact our health as well.”

The study has been published in the journal Psychological Science.
