A surprising, liberating and scientifically informed guide to overcoming the anxiety that permeates modern life. How many cups of coffee should I drink? Are work meetings really worth the time? Do I really have to floss? Award-winning public-health expert Timothy Caulfield tackles our daily dilemmas—from the moment we wake up to when we go to sleep—and the innumerable cultural, social and psychological forces shaping the decisions we make. Too often these decisions are dictated by concerns or beliefs about our world that simply aren't true. Caulfield shows that these misperceptions unnecessarily stress us out and cause us to waste time and money. Relax reveals a science-informed way out of this mess, helping to put your mind at ease.
