“…This repetitive and extended physiological responding is proposed to cause wear-andtear on the body that over time leads to disease (Brosschot, Gerin, & Thayer, 2006;Smyth et al, 2013). Such an explanation helps to account for why rumination has been found to be associated with a range of poor psychological health outcomes, including depression (Hong, 2007;Thomsen, Mehlsen, Christensen, & Zachariae, 2003;Zawadzki et al, 2013), poor sleep quality (Thomsen et al, 2003;Zawadzki et al, 2013) and anxiety (Nolen-Hoeksema, 2000).
