Is it time to stop worrying about stress?

Assuming that negative emotions are inherently unhealthy can have terrible consequences. We currently live in a global "Don't Worry" club, where we're frequently told about the dangers of stress and what we should be doing to overcome it. However, a growing body of research now suggests that it's not negative emotion that has dangerous effects on our health but our feelings about it. Award-winning science writer David Robson discusses how our attitudes change how we perceive our environment and even change our physiological responses to stressful situations influencing our health.
