While the days leading up to most presidential elections carry a certain frenzied, exhausted energy fueled by attack ads and nonstop robocalls, this election cycle has felt abnormally anxiety-inducing for many Americans. “We’re certainly in the middle of a perfect storm,” said Dr. Esther Sternberg, research director at the Andrew Weil Center for Integrative Medicine at the University of Arizona.
