We tend to think that big, stressful events (death in the family, divorce) are the ones most detrimental to our health. But the everyday ones matter just as much.
Researchers at the University of California, Irvine surveyed more than 1,000 people, asking them to document their daily stress caused by things like an argument, a work issue, or something bad happening to a friend, as well their physical activities, for about a week.
Ten years later, they followed up to find out whether participants had chronic illnesses, heart disease, or cancer.
They found that those who habitually let go of negative emotions have better overall health later in life. It’s possible that holding on to negative emotions is tied with traits such as neuroticism, rumination, and depression, which can manifest as health issues.
