According to Gallup’s annual Global Emotions report, people all over the world are more stressed than ever before. Nearly 40 percent of adults from 146 countries reported having experienced worry or stress. And it isn’t just adults experiencing these high stress levels; experts have also observed a rise in the number of children and youth. According to another study published in EurekAlert, one in five students are so stressed that they’ve considered self-harm or suicide. The immense stress they face has been proven to be harmful to their health.

It’s no news that stress can trigger anxiety, depression and self-harming behaviors, and cause sleep problems, social withdrawal, angry outbursts and obsessive-compulsive behaviors. We are moving towards a society where an increasing number of us face mental health problems that stem from high stress levels. If stress increases rapidly, how can we fight it?

It might sound easier said than done but studies have shown that the best way to deal with stress is to change your perception(认识) of it.

The University of Wisconsin conducted a study of 30,000 Americans. Researchers asked them how much stress they’d experienced in the past year and whether they believed stress was harming their health. The researchers concluded that people in the study who were exposed to large amounts of stress and viewed stress as harmful had 43 percent higher risk of dying than people who viewed stress as a helpful response.

More interestingly, those with more positive perceptions of stress had the lowest risk of death out of all involved in the study, even lower than those experiencing very little stress.

A separate study conducted by researchers from King’s College London and the University of Marburg showed students with more negative beliefs about stress experienced more physical symptoms, such as headaches, tension and tiredness during a stressful end-of-semester exam period, compared with students who had more positive beliefs about stress.

These two studies have proven that stress itself is not actually bad. It is the belief that stress is bad that is bad.
