Stress enhances performance: The Upside of Stress by Kelly McGonigal

In Kelly McGonagall’s book “The Upside of Stress,” she posits that stress, contrary to traditional belief, can be beneficial when perceived positively. For many years, the prevailing view held by psychologists and scientists, including Kelly herself, was that stress was detrimental to health. However, recent research suggests that changing one’s perspective on stress can alter its physical effects. For instance, those who see stress as enhancing produce a chemical called DHEA, which helps the brain grow stronger from stressful experiences and counteracts some harmful effects of other stress hormones. Additionally, stress can lead to the release of oxytocin, often referred to as the “cuddle hormone”, which promotes connection with others and strengthens vital organs like the heart.
