Imagine discovering that one of your core beliefs about health might actually be killing you. This was Kelly McGonigal's shocking realization when she encountered research showing that believing stress is harmful was associated with a 43% increased risk of death - making this belief more deadly than skin cancer. As a health psychologist who had spent years warning about stress's dangers, this revelation transformed her perspective. What if our relationship with stress, not stress itself, determines whether it harms or helps us? The science reveals something remarkable: stress isn't inherently good or bad - it's a natural response that can either enhance our lives or diminish them, depending largely on how we perceive it. Your thoughts about stress literally change your body's response to it. In a groundbreaking experiment, Stanford psychologist Alia Crum divided participants facing a stressful job interview into two groups. One group watched a video portraying stress as enhancing, while the other saw stress depicted as harmful. Though both groups experienced increased cortisol, those who viewed stress positively released more DHEA - a neurosteroid that helps the brain grow stronger from stress. This "growth index" predicts resilience and recovery from trauma. This isn't just a fleeting effect. When employees at UBS bank during the 2008 financial crisis received training on stress's positive aspects, they reported less anxiety, fewer health problems, and greater productivity - despite experiencing the same high-stress environment as colleagues. Your mindset creates cascades of thoughts, emotions, and behaviors that become self-fulfilling prophecies. Those with positive stress mindsets tend to face challenges directly, seek support, and find growth opportunities, while negative mindsets lead to avoidance, substance use, and withdrawal - approaches that ultimately create more problems than they solve.
